The Ins & Outs of Barrel Care, Inspection, and Tracking

By: Gerald Dlubala

A lot of love, time, and work goes into a winemaker’s final product. But there’s also a lot of money and equity tied up in the barrels that hold, age, and nurture that wine. Barrel inspections help protect your product and livelihood by revealing potential leakage areas in the barrel along with any cracks, gaps, or over-toasting, which can directly or indirectly contribute to spoilage, foul aromas, or an undesirable taste in your wine. The stave and head joints should be narrow and tight, with solidly fastened hoops and a tapered bunghole. Bung holes are a common source of spoilage and contamination, and those with cracks emanating from them can be an unwanted source of excessive oxidation.

Storage and Use:

NEW BARRELS

  New, empty barrels can be stored indefinitely when regularly maintained and kept in cool, humid conditions to lessen the possibility of shrinkage, preferably in the 55°F (13°C) range with 65-75% humidity. Prepping for storage includes a thorough, clean water rinse and complete drainage before performing a Sulfur purge and bung insertion. In addition, routine checks on Sulfur levels must occur to make sure the levels remain consistent.

  Before filling with wine, the stored barrels must be swelled to seal any minor cracks that could cause leaks leading to oxidation and potential mold growth. If Sulfur purging was used in the storage process, release the gas and give the barrel an additional warm water rinse before swelling. Fill the barrel within 20% of its total volume using clean, hot water. Insert the bung and flip and rotate the barrel looking for signs of leakage or agitate the barrel for accelerated swelling until there are no more signs of any leakage. Thoroughly drain the barrel and let it dry and cool down before use. But if leaks are still evident, an overnight swell may be needed, which entails filling the barrel and soaking it overnight. Any leaks should swell shut and stop leaking after a few hours or at the most after a couple of days. Never let a long soak go more than 36 hours without changing the water inside due to the potential for mold growth. When the leaking stops, drain water with the bung side down, and after complete drainage, it is ready for use. If an overnight swelling process doesn’t work, the barrel is likely unfit for use.

Used Barrels Need Different Care

  Increasingly, used barrels are only water rinsed before being used for wine storage because the previous contents can be a desired addition to the flavor profile of the wine. Used barrels can also be rinsed several times and stored empty after being purged with Sulfur. Sulfur levels must be checked monthly on the stored barrels and replenished as needed. The stored barrels will shrink over time and need to be swelled again before filling. An alternative to the traditional swelling practices includes filing the barrels with a Sulfur-citric holding solution that promotes sterility and helps promote swelling and shrinkage control. The downside to using a Sulfur citric solution is that it strips the natural wood extract flavor and the desirable oak flavor properties. So it is not recommended for use on new barrels or those less than a year old. The Sulfur citric solution strips natural wood extract flavor. The use of holding solutions requires thorough rinsing procedures before a winemaker can reuse the barrel.

Spoiler Alert

  When wood comes in contact with liquids, especially wine, it becomes a natural breeding ground for bacteria and spoilage mechanisms. If your wines have pH levels above 3.7pH combined with low sulfite levels or residual sugar, lactic acid bacteria can cause spoilage and produce a sour milk taste.

  Acetobacter (Acetic Acid Bacteria) causes the alcohol in your wine to convert to acetic acid. When combined with the deposits left due to poor rinsing of barrels or lack of or improper Sulfur purging, Acetic acid forms ethyl acetate, the ingredient used in nail polish remover. It frequently happens with wines that oxidize and have headspace, producing the familiar vinegar aroma.

  Brettanomyces Yeasts in your barrels mean spoilage. They metabolize very low sugar levels in wine or the cellulose sugars in the wood due to insufficient Sulfur purging of stored barrels or the inadequate presence of sulfites in the barrel. Brettanomyces Yeasts produce an aroma reminiscent of a well-stocked medicine cabinet.

  Penicillium mold is one of the most common concerns for winemakers, usually originating through stave or head joints or around the bunghole. Hard to eradicate once it gains a foothold, penicillium mold causes foul aromas when in contact with the wine.

Keep Track and Maintain Consistent Barrel Information

  When maintaining and storing your barrels, a system for keeping track and maintenance schedules can be quite helpful, and a winemaker should choose a system based on their specific needs and budget limitations. Limited budgets can make practical use of barcode-based barrel tracking systems that provide inventory and location data for their in-house barrels. If you need more information, like maintenance schedules, barrel history, or tracking information, you may need the benefits of Quick Response (QR) or Radio Frequency Identification (RFID) code technology. Economic factors can lead you to use QR codes for increased data storage with easy read capabilities. However, RFID is a great choice when considering pure efficiency, with passive RFID providing more data storage, faster scanning, and additional location and temperature tracking capabilities over their QR counterparts. With the additional cost of active RFIDs, you can have real-time location data, temperature readings and humidity levels.

  Barcode tracking systems are an option that is associated with most if not all things around us. The familiar series of one-dimensional lines constructed of variable thicknesses encode numbers and characters that provide the object’s unique identification number that links back to a database providing all pertinent inventory, maintenance, and barrel information needed for your winery. Barcode labels are economical and easy to read with handheld devices or available smartphone apps. However, the location of the barcode label is critical to correct readability because the barcode label must be within the sight and allowable parameters of the reader.

  Quick Response (QR) Codes are the pixelated squares scanned from a smartphone camera to send you to another location or web link. They can be combined with GPS functionality for barrel tracking and store up to a hundred times more information than the basic barcode. If needed, once a barrel is assigned to the database, the winemaker can add more specific barrel information. Unfortunately, paper-printed QR codes are susceptible to humid conditions and durability issues. More durable options increase cost, and if Wi-Fi is needed, that can be an issue in wine cellars.

  InnoVint Inc, founded in 2013, is a bud break-to-bottle wine production software company made up of winemakers. Their wine production software optimizes QR codes for wine barrels that are easily scanned on a phone or tablet and allow details on contents, activity, barrel history, and more to be entered. Their QR codes scan well in dirty, wet, or humid conditions and stay with the same vessel for its lifespan while in your cellar, making historical information accessible and easy to retrieve. This information can include things like fill dates or Brix readings for your fermentation tanks. Using InnoVint’s software, the QR codes can be printed or reprinted on demand.

  Radio Frequency Identification (RFID) uses radio waves to track objects and their unique data. You won’t need a direct line of sight for this type of tracking, and it scans faster than pointing at a barcode or label. Using Active RFID brings the ability to read from up to 100 feet away with more memory. The RFID tags transmit a continuous signal with real-time statistics. More size and memory bring additional tracking and information functionality, including temperature, humidity levels, and real-time location statistics. But, because they are battery-powered, they are bulky and more costly.

  Passive RFID codes, on the other hand, are smaller, more compact, and not reliant on an enclosed battery, making them more economical and longer-lasting than active RFID tags. Passive RFID tags can be inlaid into sticker form or attached like tags, making them more durable and a good fit for wine cellars or barrel storage areas. They are stable under diverse conditions while having the ability to record both interior and exterior temperatures. Passive RFID has more limited data storage capacity but is compatible with real-time location systems for immediate tracking capability. Additionally, available location and temperature data allow variation tracking in temperature versus barrel volume fluctuations and free SO2.

BarrelWise: Enhanced Technology For Wine Production And Analysis

  Barrel management is time-consuming and manually labor-intensive, especially for craft wineries. BarrelWise is a project initially conceived and targeted for another industry by a group of University of British Columbia (UBC) students, including Jason Sparrow, now CEO, and Artem Bocharovaz, Director of Sales. By listening to and addressing winemakers’ concerns, they’ve taken their idea and created a system for winemakers that incorporates specialized bungs and a unique hose cart for each wine barrel that allows winemakers to take measurements and top off the barrel with a straightforward action. After successful trials with several wineries fully outfitted with BarrelWise bungs, BarrelWise is building and adding sensing operations to their units.

  Smaller wineries can more easily test all of their barrels for free SO2 levels, but Sparrow said that higher producing wineries test as few as five to ten percent simply due to time constraints. In addition, wine barrels routinely have an evaporative loss that may require topping off. With the BarrelWise system, the barrels can stay in place and provide data through their head sensors, allowing winemakers to top off, test, and correct and SO2 levels simultaneously, saving labor and time. By testing every barrel, a winemaker reduces the inherent risk in producing larger batches of wine. Critical decisions are made based on accurate data from each barrel, giving the winemaker more control, confidence, and efficiency in their decision-making. Individual barrels can produce significant variations, and BarrelWise helps the winemaker get each barrel right through easy measurements, accurate data and consistent tracking

Software for Wineries: High-Tech Launches Wineries to New Heights in Productivity

By: Cheryl Gray

Wineries worldwide use technology to their advantage when it comes to saving one of their most important assets––time. The right software applications simplify collecting, sorting and maximizing data. The type of software to use often comes down to the winery’s size, its specific needs and finding the best return on investment.

VinNOW

  Wineries with small budgets but big plans can turn to VinNow of Mesa, Arizona. The company was founded in 1999 by software engineer Ted Starr. VinNOW is designed to operate in either a single, stand-alone computer environment or a network of multi-POS operations and multiple locations.

  “VinNOW runs securely on your computer, not in the cloud. This ensures that if you lose your internet, you still have access to all your data and can still make sales. Having the program and your data on your local network also allows for better data security and gives you the peace of mind that you can do your business no matter what,” said Starr. 

“VinNOW is one program, using one database, that stays in your local system’s control. This is the advantage of having been created by winery owners: Knowing the winery environment and challenges.”

  With 40 years of industry experience, Starr and his team have poured their expertise into developing a versatile software program to suit wineries of any size. Starr added that customer support comes from a team knowledgeable in both software engineering and what wineries need to maximize production. 

  “VinNOW is comprised of professionals with many years of experience in both computer technology and the wine industry. Our expert team is intimately familiar with a winery’s needs and has the technical knowledge to offer and support our specialized integrated system for winery management. VinNOW was created by winery owners who are also software developers and have decades of hands-on winery experience. VinNOW offers a personalized and specialized approach that is dedicated to, and in touch with, the business needs of a winery,” Starr told The Grapevine Magazine.

  “VinNOW is dedicated to providing a quality, comprehensive software application specifically engineered to meet the needs of the wine industry. We provide personalized live customer service and support and pride ourselves in remaining a hands-on, efficient company. This means that when you contact us, you will be dealing with someone who understands your needs and can directly and personally handle any question.

  “With VinNOW, you don’t just receive a software package. You enter a relationship with a software company that has been in the wine business for over 22 years and is directly interested in the health and prosperity of wineries. Should you need us, our support team is available seven days a week to assist you with VinNOW. Our VinNOW support team is always eager to answer your questions and assist you with what you want to accomplish.”

  VinNOW, Starr said, is a fully integrated software system that is ideal for managing inventory, customer data, purchase records, tasting room and internet sales. The software program also manages email marketing and wine clubs with automatic credit card processing. For shipping needs, VinNOW generates UPS, FedEx and GLS shipping labels. VinNOW also allows wineries to track those shipments. It integrates with other software programs such as QuickBooks, Vertical Response, Constant Contact, VinoShipper and ShipCompliant. It also can export information to other email systems.   

  Another innovation from VinNow is VinTracker, a bulk wine tracking module. Starr says that VinTracker allows wineries to track products, everything from what wine is in which containers to what work has been performed on-site.

  Starr said that VinNow allows its winery clients to provide customers with targeted messaging rather than generic correspondence, which is vital to keeping and expanding a winery’s client roster. COVID-19 made this function a critically important tool. 

  “One of the challenges wineries have in a COVID-19 environment is keeping in touch with their customers in order to maintain and keep interest in that business relationship. VinNOW excels at data reporting and allowing a winery to target market instead of having to send the same generic message to everyone,” said Starr. “With VinNOW, wineries can create lists for an almost unlimited set of data points. For instance, you have the ability to create a list of people who have purchased above a certain dollar level, a specific varietal, has purchased futures in the past or are just on an interest list or in a specific range of zip codes. 

  “You can then refine your search to target market customers such as those associated or never associated with a wine club, or even inactive wine club members. Any data element that VinNOW captures can be used to create a specific marketing list to meet your needs.”

Dimensional Insight

  Helping wineries keep in touch with their customers is also a focus of Dimensional Insight, in business since 1989. Headquartered in Burlington, Massachusetts, Dimensional Insight is an analytics and data management firm specializing in integrating data from different sources and displaying the information wineries need in whatever way they need to see it. The company’s trademark Diver Gateway product allows access to data on any device. Its applications are specific to the wine industry for both wineries and distributors. Nancy Berkowitz serves as Industry Vice President.

  “Users of our software have the flexibility to do self-service reporting and analytics while ‘diving to the lowest detail’ from dynamic dashboards and scorecards. As a result, they are able to get unprecedented insight into the state of their business, and can make better, more informed decisions that help drive increased sales, bottom lines and customer satisfaction,” said Berkowitz.

  With COVID-19 mandates changing the wine industry, not to mention overall industry-driven shifts, wineries have to focus and pivot quickly. Berkowitz told The Grapevine Magazine that Dimensional Insight can help them do just that for data management and analysis.

  “In this economic climate, where there are fundamental shifts in how people are buying products and what they’re buying, it’s most important for wineries to look at not only the bottom line but also any associated numbers. What is changing? Are these short-term changes or long-term changes? To best assess this, wineries need to look at their outlier data to see what the causes for these changes are and determine how to handle them,” Berkowitz said.

  “It can be hard to pinpoint some of this data when you have huge data sets that pull together many diverse sources. That’s why we have an assisted analytics tool that uses AI to proactively look for these outliers or different data points and helps bring these issues forward for analysts. Wineries should make sure they look at not only sales and pricing data but also all data affecting the changes––operations, marketing, finance, economics and more. Then they can focus on short-term and long-term bottom-line goals based on what they discover.”

  Dimensional Insights also offers its winery and distributor clients other unique options and partnerships to expand their businesses.  

  “We also collect daily invoice level data from distributors for wineries through our BeverageLink division. Dimensional Insight has partnerships with the NielsenIQ as part of the Nielsen Connected Partners program and the National Alcohol Beverage Control Association for data relating to sales, pricing and more.” 

  Berkowitz said that Dimensional Insight looks to the future of winery software to increase its use of artificial intelligence and cloud services because of the large amount of data to be handled. 

  “Artificial intelligence is a focus for software and technology. This must be taken for what it is and must truly be understood by the wineries. Not just the results, but why those are the results of the AI software. Otherwise, the results can’t be trusted. Wineries are moving to the cloud for better service and lower costs. We offer the Dimensional Insight cloud for this purpose. All in all, we see technology continuing to move toward better data integration so wineries can capitalize on the data available such as eCommerce and more.” 

Innovint

  Napa Valley’s InnoVint, founded by Ashley Leonard in 2013, combines the expertise of winemakers and Silicon Valley software engineers with a focus on providing winery clients with mobile, flexible and intuitive winery management software designed to save time and streamline the production process. InnoVint is 100% cloud-based, which means that wineries can access the software wherever they are on any device. The company touts ease of use, saying that small wineries can use the applications in less than an hour. InnoVint offers training and an online support center.

  Experts agree that winery software will continue to be a critical tool for successfully expanding a winery business by keeping a connection with the most crucial element of that success—customers.

Why Everyone is Talking About Organic Wine

By: Hanifa Sekandi

2 red wine glasses

Is organic wine a hangover cure? Could this be the answer you have been looking for to quell your day after Reisling’s woes? If it is possible to imbibe and wake up early without the thunderous plus of a headache to remind you of the night before, then surely everyone wants in on this vino du jour. Eating organic greens, grass-fed meat, and poultry and reading the labels of packaged or premade foods to see if they contain preservatives has become ever more pressing. Understanding the connection between what goes into our body and how this impacts one’s overall well-being is at the forefront of consumer goods. It is not just the food industry but also the beverage, wine, and spirits sectors. The scientific revolution ushered in a lot of excitement where increasing the shelf life of food with the use of additives seemed like a promising endeavor.

  Sometimes novel ideas have a downside. In the case of preservative-laden consumer goods, things are not always as they seem. The zealous approach to preserve anything and everything did not take into account the impact such ingredients may have on individuals on a long-term basis. Yes, one could argue that not all additives are bad for you and are necessary. Particularly when one thinks of vintage wines that would indeed spoil without the use of sulfur dioxide (SO2). You are certainly not going to find an organic aged Bordeaux or Pinot Noir that is organic. Alas, most wine enthusiasts understand this and know when purchasing organic wines that the lifespan is short therefore, these wines are meant to be enjoyed upon purchase. The distinction of what constitutes an organic wine is not universal and differs from country to country. The United States has taken on a more stringent approach than Europe and Canada.

What is Organic Wine?

  Since the designation of organic wine varies around the world, it is a case of it depends on where you live. This requires consumers to do their due diligence and research to understand that not all organic wines, although placed in the organic wine section, are made the same. Some organic wines may contain sulfites. If an allergy or sensitivity is a concern, then knowing how to read wine labels is essential. You might be wondering, what exactly are sulfites? Sulfites are preservatives used to maintain freshness and prevent bacteria growth, and in the case of wine, to reduce oxidation.

  Sulfites also influence the taste and appearance of wine and increase shelf life. So that well-aged full-body vintage wine contains this preservative. For some people, sulfites are a sensitivity or allergen that may result in side effects. This ranges from a headache to a rash, hives, stomach pain, swelling, and in severe cases anaphylaxis. Wine free of added sulfites is favorable for individuals with this concern. Keep in mind that even organic wine contains a small amount of naturally occurring sulfites.

  In the US, wines that are labeled organic must be made with organically grown grapes. Winemakers adhere to the rules and regulations of organic farming therefore, the use of fungicides, pesticides, chemical fertilizers, and herbicides is not allowed. The same standard used to evaluate organic foods by the United States Agriculture department is used to assess organic wines. There is no acceptance for simply using organic grapes. It also extends to how the wine is harvested and the yeast utilized for fermentation. Also, how the wine is stored must follow organic processing standards to receive a USDA organic certification. Before storage potassium metabisulfite is used to sterilize and sanitize non-organic wine barrels which would, in turn, impact an organic wine and hence is not permitted. Another rule is that additional sulfites cannot be added to organic wine and if so, it will not be deemed organic by the National Organic Program.

  A wine bottle labeled as “Made with Organic Grapes” signifies that this vintner used organic grapes for their wine but there are added sulfites. Winemakers who choose to produce wines with preservatives are permitted to use non-native yeasts (yeast that is not organic) during fermentation. They may also use up to 100 parts per million additional sulfites. In Canada and Europe, sulfites are allowed and this distinction is made on wine labels. If you see a wine labeled “100% Organic” in Canada, this means that it is made with certified organic grapes and does not contain added sulfites. A regulation distinction that falls in line with the regulations found in the US. A wine with this certification would be permitted for sale in the US since it meets the strict requirements. 

Not All Wines Are Made Equal

  The European Union has allowed the terminology “organic wine” on wines made with organic grapes but contain sulfites. Whereas organic wine in the US must contain less than 20 parts per million of total sulfites to get an organic seal of approval. This departure in regulation has limited European wineries who consider their wine as organic to enter the US market and be designated as such. Vintners in France and Canada, for example, countries that both allow for some leniencies. Argue that additives permit stabilization and longevity of wines. No preservatives mean these wines have a short lifespan — only a few years after bottling. 

  The solution would be to pivot the same way the food industry has and look for organic preservatives to maintain the integrity of the wine. It is hard to change a processing practice that has proven fruitful and effective. Further, this niche wine selection is still in its infancy. Perhaps the growth in organic wine consumption in places like France, where the drinking of organic wine has seen a dramatic increase in the last few years and continues to grow. May usher in an innovative way to preserve wines. Germany is the leading organic wine-growing country.  Vintners in Germany could take the helm and steer this aim in the right direction. If it can be done in the food industry, it is only a matter of time before an expert winemaker finds the solution or middle ground.  So there can be a fair import and export of organic wine trade with European, Canadian, or other organic winemakers worldwide who have a strong desire to enter the robust organic wine market in the United States.

  As more vineyards in France convert to organic they may take the lead as premier organic wine producers and surpass Germany who has the most amount of organic vineyards. With an increase of organic wine producers in France, which houses approximately ninety percent of the global organic wine-growing regions. France has a surplus of wine reserves more than the percentage of organic wine drinkers in its country could possibly drink. Hence, getting access to more consumers in this niche is essential. The US, with its strict regulations, has a high demand for this niche market. But, it lags considerably behind other organic wine-producing regions in production.

An Organic Viniful Future

  By 2023 an estimated 1 billion bottles of organic wine will be consumed. Germany takes the lead with the consumption of the most organic wine consumed. But this might be due to availability more so than popularity; proximity and ease matter. And setting a high standard for quality and wine cultivation has been the norm for German vineyards for decades. 

  Whether or not wine-producing countries will agree on what makes a wine organic. The reality is there is a demand for wine producers to not only take on sustainable cultivation methods but also consider what goes into each barrel of wine they make. As trendy as hangover-free wine may be, it is more than just about staving off a headache it is about the food and beverage industry’s responsibility to their consumer. Understanding that there need to be options. There is a fine balance that can be met.

  Further, organic wine enthusiasts are not necessarily bidding adieu to classically-made wines; they simply desire choice. If organic wines could be the answer to hangovers or possible side effects for some, it is worth exploring for those looking for an alternative. Of course, there is no direct evidence to support the notion that organic wine is the answer wine drinkers have been looking for to solve a dreaded hangover.

  It cannot be argued that people are finding that organic wine does not have the same side effects as its older sibling wines that contain additional sulfites. This is why it has gained a lot of popularity among health-conscious consumers who tout this day-after pleasant effect.  Another step that organic winemakers are moving towards is producing wine with lower sugar content. This coupled with no additional sulfites could be a winning strategy since high sugar content in alcohol is also responsible for the horrible day after feeling that many feel after one too many.

  As the organic wine industry grows and consumers demand cleaner options. The old school way of making wine and the new school approach will need to find a happy medium. So, wine drinkers can continue to experience the rich history of a slowly-aged oak barrel wine while welcoming a fresh organic wine that compliments a modern lifestyle.

Notable Organic Wines

Dry Farm Wines: This vineyard goes a step further and calls its wines pure Natural Wines. They take on a purist approach when it comes to farming and harvest pure natural wines that are not only lower in sulfites but are sugar-free, vegan, biodynamic/organic, free of toxins, contain lower alcohol and keto, and paleo-friendly. Sounds like wine magic, right?! This winery offers a great selection of reds, whites, rose, and sparkling wine. They offer you an opportunity to try a box of different wines and if you would like monthly subscriptions.

Frey Vineyards: As the first US winemakers to be certified organic and biodynamic, Jonathan and Katrina Frey have been crafting organic wines for over forty years. A standout quality of the vineyards where their wines are made is that they use a biodynamic farming method which means that the natural habitat where their vines grow is cared for with consideration of the animals and plants that inhabit the land. The 2018 Biodynamic Chardonnay with a smooth vanilla creamy finish is a delightful organic selection.

How’s Your Mouth Feel?

By: Tod Stewart

couple drinking wine

The latest vintage of Domaine de la Bon Bouche sets the lips tingling as if tickled by the eyelashes of an angel as it flits on gossamer caresses, coming to alight gently on the tongue. Resting its silky wings, it envelopes the palate in a cocoon of velvety, glycerol-induced unctuousness. Wrapped in a creamy, viscous robe, it perches supplely on the papillae, mustering the steely resolve required to resume an ultimately suicidal (though heart-arrestingly warm and generous) slink down…down…down. Without gritty tannin, without harsh heat, without even a suggestion of chalkiness, it bids, adieu mon amour to my spent taste muscle and departs in a gush of crisp, crunchy yet at once satiny tactile replay.”

Sick of this yet?

Me, too. So let’s get on with it.

  Obviously Domaine de la Bon Bouche is not a real wine, winery, or marketing gimmick (okay, hold that last possibility). Nor is the “review” the product of a real “wine writer” (though considering some of the reviews I actually have had the displeasure of reading, it’s not much of a stretch to think it could be).

  However, if you study that exercise in vinopomposity you’ll notice something interesting. Not once…once…were aromas and flavours ever mentioned. Coincidence? I think not (mostly because I wrote it that way on purpose).

  The point, insofar as there is one, is that there’s a dimension to wine (and spirits and beer and all the other goodies that slide over your palate) that goes beyond smell and taste. It is the middle ground between light and shadow, between science and superstition, and it lies between the pit of man’s fears and the summit of his knowledge. This is the dimension of imagination. It is an area which….(Sorry, but I’ve been dying to shove the “Twilight Zone” intro into one of my bits.) Actually, it’s the dimension of the tactile and it is the zone where those elements that give wine textures roam. The things that make them “silky” or “furry.” “Gritty” or “velvety.” “Round” or “sharp.”

  A highly extracted Alsace Gewurztraminer can come off as almost oily or “creamy” on the palate. A brisk, unoaked Chablis can be steely. A raw young Cabernet will be puckeringly astringent. These non-flavour components are responsible for what the cork dorks generally call “mouthfeel.” When a wine has a particularly noteworthy mouthfeel you tend to resist the urge to swallow it right away. Instead, you hold it in your mouth, roll it around, maybe even chew on it a bit before sending it on its way.

  Some of you, perhaps a very few of you, might care to know where these textural elements originate. Given that I fall into the latter group, and I’m writing this, I’ll give it a brief once over then let the truly curious Google the night away.

  Rumour has it (or maybe it’s actually the truth, who knows, but I’ve got a deadline pending and can’t waste too much time researching), that two French dudes named Semichon (which, translated, means “half chon” and shouldn’t be confused with Semicornichon, which, translated, means “half little pickle”) and Flanzy (whatever) suggested (to whom nobody is sure) that substances called pectins produced tactile sensations in the mouth. (Actually, a fellow named von Follenberg discovered these things in 1914, but it’s harder to riff on his name.)

  Pectins fall into the larger phylum of polysaccharides, and within this party of “Ps” reside a few interesting members including Arabinogalactan proteins (AGP’s – originating in a galaxy far, far away populated – secretly – by those of Arabian descent), Type II Rhamnogalacturonas (RG-IIs; sung, albeit with difficulty, to the tune of The Knack’s My Sharona) and Mannoprotiens (MP’s; typically found dozing in Canadian parliament but also, apparently, found in wine – or into wine, as the case may be.) By the by, I’m not making this stuff up, at least not the names; the descriptors are, however, proudly my own.

  I’ve never really been a “leg man” when it comes to wine (and let’s just call them “tears” instead of legs), but the thickness of those somewhat syrupy-looking trails that slither down the inside of the glass point to the presence of glycerol (and alcohol). The more glycerol the “oilier” or more viscous the wine will feel on the palate.

  Anyway, numerous tests concluded that these fine thingamajigs do, in fact, combine to alter the textural nuances of a wine. And efforts have been made, usually by the pointy-heads, to analyze, categorize and compartmentalize tactile variants. The results, for good or for ill, being “texture wheels” (similar to the oft-cited UC Davis “aroma wheel”).

  So now we know what creates texture in wine. But what causes textures to differ? The answer is found in both nature and nurture. 

  “But how is this going to impress my dinner guests/date/boss/Arabinogalactan-in-waiting?” you whine annoyingly. To which I answer, “All good things in time, grasshopper.” But seeing as there’s no time like the present, here we go.

  If you think about it, texture factors largely in how a wine will tango with a particular morsel of food.

  The zesty, electric acidity and mild sweetness of a kabinett level German Riesling offers the perfect foil for a creamy/salty dish, while the cleansing sparkle of a fine glass of fizz drums down the oily character of smoked salmon. The drying astringency of an austere young Bordeaux can be quelled by the proteins in a rare steak. And like the flavours and aromas of a wine, its texture can change with age.

  Some feel that the texture of a wine is the most important aspect of the whole experience. David Ramey of Sonoma’s Ramey Wine Cellars is one of those types. How important is texture to him? “From my perspective, it’s huge. I don’t care if a wine smells like apples, peaches or whatever, but I really care that it feels good in my mouth. Focusing excessively on a wine’s aroma is like focusing on cologne while making love – it’s not the main event.” I’ll take his word for it.

  Here’s something you can try at home (where else these days?) with minimal cash, fuss and planning that will show you how wine and food can both complement and contrast, and how important the textural aspect can be in making food and wine matches work.

  Get yourself a brisk, zesty Sauvignon Blanc (Loire Valley, Niagara, California, New Zealand, etc.). Hit up the cheese monger for a creamy/crumbly young goat cheese, and the fish monger for a few fresh East Coast oysters. Don’t mess with the purity of the oyster by adding gloopy condiments; knock it back au naturel on the half-shell and follow it with a gulp of the wine. The bracing acidity of the wine marries nicely with the briny bivalve creating a sensation of textural lightness. Now try the same routine with the cheese instead of the oyster. The tang of the young cheese matches the zippy grapefruit zing of the wine, but its palate coating creaminess welcomes the wine’s cleansing quality. A great textual match, but on an entirely different level.

  I recently (finally) got out of the house to celebrate the reopening of Chef Daniel Boulud’s Café Boulud in the swanky Four Seasons Hotel Toronto. Not only was I treated to a rather spectacular lunch (with some to-die-for duck), I also had the extreme pleasure of matching the various dishes with wines from one of my favourite Champagne houses: Ruinart. I asked the hotel’s Wine Director and Sommelier, Julie Garton, what her views were on the importance of textural elements in wines.

  “Texture in wine can be very important for pairing,” she informed me, “especially with red wine as it tends to have higher tannin levels. Many factors contribute to the texture/tannin level of wine, including the thickness of the grape skins, ripeness of the grapes, length of maceration and the vessels used to age the wine. Together, these factors can create different textures which can be described as silky, firm, plush, or grippy. As a result of the texture, the wine can pair better with different foods and cooking methods. White wines aren’t without textures either. Certain wines are known for having a creamier or oily texture despite having tannins.”

  She also mentioned that texture helps to balance the respective weights of both the wine and the food matches. Champagne, she assured, made for a fantastic food-pairing partner, notably due to its textural elements. I nodded in agreement (as it is rather bad manners to talk with your mouth stuffed).

  “The bubbles can certainly help to add a creaminess to the texture of the wine. However, often the production method, for example, barrel fermented and aged, along with the dosage level and the type of grapes used tend to have the largest impact on the weight and texture of a Champagne. An Extra Brut Blanc de Blancs will often feel leaner on the palate than a Blanc de Noirs, or a Vintage Champagne, which with age will show more richness.”

  Favourite matches? “A pairing I’ve always loved is Champagne with fried chicken,” she admits. “Champagne is great with fried foods because of its high acidity. The acidity and the bubbles help to cleanse the palate and cut through the fattiness and oiliness of the dish.” Which also confirmed another wine and food rule: simple wine with complex food; complex wine with simple food.

  In the end, writing about wine textures can be a bit difficult, mostly because it’s writing about something we feel. And what we feel, as we all know, often goes beyond words. 

Vineyard vs. Vineyard: Water Is The Great Unequalizer

grapes submerged in water

By: Orest Protch

The Impact of Water Irrigation is more then turning on your Sprinkler or Drop Irrigation. Although the water you see may look, well, boring, when you delve deeper into its secrets, you are entering the realm of rocket science, with a dash of magic and a pinch of voodoo.

  Vineyard water chemistry is more than just pH and a few other high school level chemistry tests. It can possibly explain why some vineyard wines can be award winning some years and other years be best forgotten.

  Vineyards take their raw water from lakes, rivers, water wells and in some cases use treated potable municipal waters. No two waters carry the same chemical and nutrient loading. And this loading taken from the same source can even vary daily, monthly and yearly.

  One side of a lake may have different water chemistries than the other due to the way water flows through it. It can have numerous streams and rivers feeding it, each draining a different watershed. These may be draining mineral outcroppings, storm sewers, municipal wastewater plant discharges, mines, farms and even burnt forests. Each of these will add differing kinds and amounts of chemical elements and compounds to waters. Even a few hundred meters apart, water samples will show varying amounts of TDS, total dissolved solids and TSS, total suspended solids. One stream may discharge its nutrient load farther into a lake than another.

  As an exercise, If your vineyard is on a lake or river, download a satellite image and mark its location in relation to all of the above. You may be shocked at what you see.

  At one point in my career as a research chemist in a pulp mill first owned by Proctor & Gamble and then by Weyerhaeuser, I believed that the seasonally changing chemistry of incoming river water for the mill was impacting the final pulp fiber morphologies in different ways throughout the year. The mill pumped in 6.3 million litres per hour, 24 hours a day.

  I proved that individual elements such as iron, calcium and sodium in the river water, in parts per million (ppm) and parts per billion (ppb), were impacting the final processed fiber properties by interfering at the chemical bonding sites of the fibres at the molecular (atomic) level. 15 pulp mills in both corporations changed the way they ran their processes.

The author in 1997 using an AA, atomic absorption spectrometer with graphite furnace, to do accurate and precise river water analysis. His stereoscopic microscope photography work was later verified by using scanning electron microscopes by corporate chemistry PhD’s.

  I then carried this type of testing later in my final career as a senior lab technologist for an oil company using an ICP-OES, (Inductively coupled plasma optical emission spectrometer). The flame of this instrument burns at a temperature 2,000°F hotter than the surface of the sun. I measured elements down to the very low ppb level and high ppt levels in daily/weekly process and environmental samples from lake water, river water, fresh water wells and brackish water wells. Even in the harsh industrial environment of oil production, as in the pulp mill, the changing water chemistries manifested their effects.

The author in 2018, as the senior lab technologist for an oil company, using an ICP-OES (Inductively coupled plasma optical emission spectrometer) to do elemental analysis of various types of water samples down to the very low ppb, high ppt level. The plasma flame burns at a temperature 2000°F hotter than the surface of the sun.

  Plant roots absorb the waters and simple elements such as iron and cobalt and along with plant enzymes and biological catalysts, create the complex chemicals in grapes. Throughout the complicated grape’s biological chemical processes, water chemistry changes can inadvertently modify chemical reactions and the final reaction product can change.

  What happens in a vine is the equivalent to the most complicated industrial chemical processes known.

 A vine takes simple elements from the water and soil and creates extremely complex molecular chains that would take the largest industrial facilities to duplicate.

During all chemical reactions, elements and chemical compounds look for reaction bonding sites and at the molecular level zero in on specific locations of individual molecules of plant cells. Plant cells absorb these and start creating sugars, acids, phenolics, ethonals, enzymes, montoterpenes and a host of other products that give the mature grape its final properties. But as in all complex chemical reactions, simplicity does not exist. Different atoms, due to their concentrations, may battle it out for molecular bonding sites.

  Elemental bonding sites are the drivers of all reactions. Some chemical bonds prefer other elements if they are available and so the final molecule may not be the one a vineyard wants in a grape. It all comes down to concentrations and availability of needed as well as competing atoms.

Chemical reactions do not occur with the grace and choreography of synchronized swimmers forming their final complex shapes. Instead they are more like the chaos found on the rugby field where each element tries to be the alpha and fights and blocks for supremacy and forming what can either be a desired or undesired molecule. One misallocated atom can change the properties of a molecule and a grape.

  Figure 1 is part of an actual 2019 Government lake water analysis report for the local vineyard industry. If this report had been generated by a third party commercial laboratory for me at my previous work position, I would have rejected it. Look at the number of decimal places and zeros of elements such as cobalt and iron. Research papers show all the elements in the figure are important for grape development. This analysis was obviously done on a very basic ICP, Inductively Coupled Plasma Spectrometer, found in all commercial labs.

table showing 2019 Government lake water analysis report for the vineyard industry

Figure 1: Part of a 2019 Government lake water analysis report for the vineyard industry. Most industrial chemists would reject it outright. The number of decimal places to the last number indicate the lower detection limit of the instrument used and the ‘<’ sign is like a flashing hazard light to question the analysis precision and its worth to you.

  Figure 2 is the type of analysis that an instrument like the ICP-OES that I used can give. It can reach detection levels by a factor of 100 to 1,000 lower than a basic ICP. In this case the difference between the detection limit of 5 decimal places in cadmium and chromium with 6 decimal places was the quality of the standards used to calibrate the instrument on a daily basis. Analytical standards can vary batch to batch.

Analysis from an ICP-OES
Figure 2: Analysis from an ICP-OES adds more decimal places making it more accurate and useful for better understanding of actual water chemistry.

  Why is it important for vineyards to have the most accurate and precise analysis of their waters? Just like in metallurgy and metal standards, trace amounts of elements can have large impacts on chemical and physical characteristics.

  The analysis report in Figure 1 lists iron composition at <0.010 mg/L. This is completely useless information for a vineyard and a waste of test analysis money.

  What if the mg/L of iron required to make a grape that creates that reproducible excellent wine that you are striving for is between 0.0012 mg/L and 0.0079 mg/L and anything out of that range changes your grape’s characteristics? This kind of tight elemental tolerance is the most critical aspect of a metal’s metallurgical grade. Why would the extremely complicated chemical composition of a grape be any different?

lab scientist analyzing sample

  The best instrument for extreme lower detection limits is an ICP-MS, Inductively Coupled Plasma Mass Spectrometer. It can not only easily go to the very low ppb, but to the very low parts per trillion range. A basic ICP will cost about $75,000, (all these costs in CDN$) an ICP-OES $140,000, an ICP-DRC (Inductively Coupled Plasma Dynamic Reaction Cell) $200,000 and an ICP-MS upwards of $500,000. All contract labs will have an ICP, some will have an ICP-OES and perhaps a few an ICP-DRC and only a very few will have an ICP-MS. For any given sample, the analysis cost reflects the cost of the instrument and the professional level of the analyst. For example, an ICP water analysis may cost $100, an ICP-OES analysis $150, ICP-DRC $200 and using and ICP-MS $300.

  These are all just examples and the actual costs will be determined by working with your contract lab’s client account manager. If asking for XRD analysis for leaf and soil analyis, there is only one lab that I know of in Canada where the analysts are all PhD’s. I only used that lab. You get what you pay for.

  Remember, this is a long term endeavor, much like your goals to create great award winning wines year to year.

  Your winery, land and associated equipment are worth many millions. The quality of your wines and your reputation is priceless. Do all that you can to win awards every year. In the next article we can discuss the rocket science of soil chemistry. Cheers!

Determining Which Vegetative Index is Best for Your Vineyard

a vast vineyard

By: Michelle Podolec, Extension Suport Specialist, Cornell AgriTech

The Takeaway

•   Canopy sensors are optical devices that use reflectance at different wavelengths to differentiate between healthy, vigorous plants and unhealthy, stressed plants. The information gathered using the sensors can help vineyard managers identify and address vineyard issues.

•   Optical sensors used in canopy sensing have improved a lot over the 45+ years since the introduction of normalized difference vegetation index (NDVI). NDVI was one of the first vegetative indexes (VI), and uses satellite-based optical sensors. It is still the most commonly used vegetative index in viticulture.

•   Other vegetative indexes use combinations of different wavelengths to measure canopy attributes. This may not only indicate leaf area “quantity” but may also identify information about leaf healthy or quality, and may add additional information to the vine size prediction.

•   More recently, affordable tractor-mounted sensors have provided close-range metrics of canopy density and health.

•   In this study of different VI, there was no clear overall winner. Researchers suggested the development of a multi-VI application that would allow vineyard owners to customize to their unique vineyard traits may offer a future potential for innovation.

vineyard apparatus in determining the vegetable index

Background

  Canopy sensors are used to differentiate between healthy, vigorous plants and unhealthy, stressed plants. The sensors used in canopy sensing have improved over the 45+ years since the introduction of normalized difference vegetation index (NDVI). NDVI was one of the first vegetative indices (VI), and uses satellite-based optical sensors. Currently, vineyards use proximal reflectance sensors (e.g. CropCircle) to collect spatial information on grapevine canopy NDVI. The information gathered can help vineyard managers identify and address vineyard issues. Most previous studies use NDVI, but there are many new modes available.

  When used, sensors are aimed at the actively growing region of the canopy throughout the season to determine leaf area “quantity” (i.e. are there a lot of leaves in the region of interest or not?) Could researchers identify the most effective VI currently available?

Methods

  In this study, researchers used the Taylor et al. (2017) protocol of sensing surveys to review a variety of commonly utilized vegetative indices and see if the most effective combination or approach to vineyard analysis could be identified. Using this method, the researchers showed that strong vines will have a high NDVI signal and weak vines will have a low NDVI signal and this correlates with vine size (measured as vine pruning weight in dormancy1). Therefore, we can use NDVI sensors to spatially map vineyard vine size and use it in our spatial crop load (Y:PW ) calculation2. Each VI was ranked, and the paper contains a useful table of rankings. The researchers found there was no overall winner VI, each performed well in at least one area.

vineyard apparatus with light

Conclusions & Practical Considerations

  No individual VI was found to be ‘best’ at predicting pruning weight. Ideally, operators would have access to a fully automated modeling software that would allow them to select the best fit for their vineyard from single or multi-VI applications.

  Further studies would be needed to adapt an automated modeling software to a wider variety of vineyards, trellis systems, soils and other vineyard traits. The authors add that there are several active projects that are looking to identify reflectance wavebands and/or Vis to identify other leaf “quality” attributes like nutrient or pest status.

Contact Seeding for Cold Stabilization

cold tanks in a facility

By: Tom Payette, Winemaking Consultant

Potassium Bitartrate Stabilization

  During the winemaking process and before bottling, there may be instability with a juice or wine termed Tartrate Stability or Tartrate Instability.  Unknowing customers often view these crystals as a fault and are therefore unsure of whether or not to consume the wine.  Once a customer is turned off by sediment, such as a tartrate precipitate, it may be difficult to get them to return to your label.  An in depth discussion below is to help winemakers achieve desired results in their cellars not undesired results in their bottled wine!  Winemakers are encouraged to make sure wines are bottled that will be sediment free.

Mechanism

  Tartrates are, very simply, a chemical salt made when potassium and tartaric acid combine making cream of tarter.  This cream of tarter [Potassium Bitatrtate] is harmless and is used, in the refined form, to cook meringues.  When most grapes arrive on the crush pad there is often a significant quantity of tartaric acid and potassium available in the grapes to result in instability.  Furthering the complication is the fact that the crystals are encouraged out of solution, forming further precipitation, in the presence of alcohol.  The fact that the winemakers have completed a successful fermentation will only force more of the crystals to precipitate. The processes to remove these crystals are largely a time temperature relationship.  Over time, and at low temperatures, most to all of the tartrates will form and fall out of solution.

3.65 pH Bifurcation *

  A very interesting phenomenon does exist with tartrate stabilization in wine made from grapes that all winemakers should understand.  (This may not apply to fruit wines) For a wine above a pH of 3.65, one should expect the pH to rise as tartrates form and fall out of solution.  For a wine below a pH of 3.65, the pH will drop to a lower pH value.  The shift, of the pH, is usually about 0.06 pH units but it can go as high as 0.19 pH units.  This knowledge can be used, factored into and forecasted by the winemakers’ ultimate plans for a certain wine’s final pH.

Tartaric acid and pH relationship

  Noting the example above, one must understand another relationship.  In both examples, whether the pH rises or lowers during tartrate stabilization, the tartaric acid level will decrease in the wine as it has formed in a salt and precipitated.  The tartaric acid has formed with potassium and become insoluble at that temperature during that time.  If the wine were to warm, however, the salt could re-soluablize negating the above statement.

Temperature and Potassium Bitartrate Formation

  As noted previously, the precipitation is largely influenced by a time temperature relationship.  Wine allowed to store over long periods of time will most likely achieve stability and it can be bottled.  With the advancement of sophisticated chilling systems in the wine industry, another process can be used.  Wines were often chilled for two to three weeks at 27 degrees F and allowed to drop their tartrates during this time.  This process was often successful but it did have its failures due to complexing agents that prevented the tartrates from forming.

Contact Seeding

  Perhaps contact seeding is more widely used today especially with wines that are blended late in the winemaking process or for getting younger wines ready for bottling sooner.  This process rarely fails and it does allow acid additions to be made even hours prior to using this process.  Some winemakers claim this action can be intrusive and beyond gentle processing; yet, others would have it no other way.

Procedure

  For those interesting in contact seeding, a procedure follows.  One must have an adequate chilling system, mixer, tanks that have little temperature stratification and a filtration system that can filter reasonably rapidly.  A properly sized plate and frame filter is sufficient for most winemakers while using a pore size pad of roughly 7 microns.  It is assumed the wine is clean enough to go through the filter pads without clogging and at a rate that will not allow the wine to warm too much potentially redisolving the tartrates previously formed during the filtration process. It is best to always check a wine first to make sure the wine is unstable before proceeding with this process.  One may be able to eliminate this process if the wine is already stable.

1.Chill the wine in need of stabilization to approximately 27 degrees F or potentially lower if the alcohol level is high enough and if greater stability is desired.  The wine will be stable at the seeding temperature of the wine at seeding so this temperature reduction step is critical.  (In the unusual case that the wine is below 8% alcohol, one would not want to chill the wine this cold.)

2.Start to mix the wine with a Guth or Keisel style tank mixer after the desired temperature has been reached.  Wait until the wine is thoroughly mixed and then double check that the desired wine temperature has been achieved and holding.  (Mixing may be done in a non-splashing pump over fashion with a pump, or two, that does not bleed any air into the system)

3.Weigh 3.0 (three) grams of Potassium bitartrate for every liter of wine in the tank.  Example:  for a 5000 liter batch of wine we would weight out 15000 grams of potassium bitartrate or 33.0 pounds.

4.Mix this amount of cream of tartar in water or wine before adding it to the tank.  (This step may be avoided but make sure no clumps exist in the cream of tarter and understand a larger quantity of oxygen may go into the wine if the substance is added dry)

5.Add the cream of tartar mixture to the chilled wine while mixing and mix for 3.0 hours or longer.  Make sure all the cream of tartar stays in solution and settling does not occur.  Make sure the temperature has remained at the desired level, as well, during this process.

6.After the 3.0 hours, mixing may stop but the chilling must remain on and continue to hold the desired temperature.

7.Allow the wine to settle overnight, or longer, if keeping the wine cold is not a concern.  [Recent research has shown an additional three days at 27.0 degrees F will improve the final conductivity results favorably on the wines.]  The wine could remain in contact with the seed for months as long as the temperature of the wine is not allowed to rise. After the overnight settling period and when filtration is desired. 

8.Vent the tank and start from the racking valve filtering on coarse filter pads making sure the filtration will go rapidly.  (One may want to remove any sediment “plug” first out of the racking valve by purging into a bucket before starting filtration.)

9.Continue to filter very cold into a clean, tartrate free, receiving tank.

10.Filter down under the manway door to the bottom of the tank as any filtration would be performed making sure to get all of the wine possible out of the tank.  Leave the solids behind.

11.If using water to push the wine through the filtration system keep in mind these crystals are water-soluble.  Make certain to use cold water and very limited amounts to not redissolve the cream of tartar making the wine unstable once again.  Do not dilute the wine with the water.  Perhaps consider using CO2 or nitrogen as well.

12.It is recommended to purge or sparge the receiving wine tank with Carbon Dioxide and the tank headspace of the wine tank being filtered during this process to eliminate or reduce the potential for oxygen uptake.  Other gases may be used such as nitrogen or argon.  (Keep in mind the principal that gases are more easily dissolved into a cold liquid solution during this step.)

13.Once the filtration is finished one may allow the tank of wine to warm and a representative sample of the tank’s contents may be taken to test that the cold stabilization action was successful and completed as desired.

14.Always double check the stability of the wine just prior to bottling and remember if more tartaric acid were added – the wine may become unstable once again.

Time / Energy / Quality

  The above process works very well to achieve cold stability.  The cream of tartar needed does have a cost factor yet the payback may be in the limited cooling cost for shorter periods of time during this process.  Others argue this process is damaging to the wine and it is over production on wine to support chilling a tank for 14 days or more.  This process will often work, yet the longer a winemaker stores a wine at cold temperatures – the more chance that the same wine will take in more dissolved gases.  This greatly increases the chance for oxygen uptake and potential oxidative reactions with that wine causes further damage.  Much of the above is determined by how each winemaker handles his or her wine and each factor should be considered.

Calcium Tartrate Stability Unaffected

  The reader should keep in mind that the process of cold stabilization in this manner does not necessarily affect calcium tartrate stability and many of the lab tests to check stability will not measure this form of instability either.

Miscellaneous Pointers:

  The winemaker must keep in mind that wines blended after cold stabilization must be reestablished or at least checked to determine their stability.  Two cold stable wines blended together will not always result in a cold stable wine and most often will reveal an unstable wine due to the chemistries of each wine and their resulting blend.  This may even be true with same blends cold stabilized separately.

  Make sure when purchasing the seed that it comes from a company that is aware of your use.  The cream of tartar seed size needs to be small enough to make sure the crystals have the proper surface for the seeding to be effective.  The seed particle size is best at 35 micrometers.  This will give the fastest rate of precipitation and growth.  A mix between 30 and 140 micrometers will do fine for this operation and is most likely the size mixture found commercially.

  One may re-use the seed from tank to tank using on whites first and then on reds.  If the seed is used in conjunction with bentonite, after cold stabilization has been achieved, then the seed must be retired.  This re-use of the seed may greatly drive down the cost of the seed per gallon as one moves it from tank to tank.  [The author has used one set of seed for over 40,000 gallons (8 – 5000 gallon tanks) of wine with success and has not experienced a failure of the process]  Cross-contamination is less of an issue at this time because the wines are generally moving toward filtration and bottling in stainless steel tanks or equivalent for sanitation purposes.

  Ion exchange and cross-flow filtration are rapidly approaching our industry.  These processes can be used to obtain cold stability should your winery have the technology and equipment to do so.

  In step three above the author has had success reducing this amount to 2 grams per liter as long as the wine is clean, chilled properly and at a desired cold temperature.

  Common sense tells us that if we can do this process in the winery, during colder winter temperatures, our chilling systems will be more effective and the cellar temperature will be more conducive to the complete process.  This applies to the filtration and making sure the wine does not warm too much during filtration.

  Be careful when rinsing the tank after filtration.  Ice may fall!

Summary

  This is just one method of achieving cold stability for a winemaker working with grape based wines.  Other ways are successful and may achieve the same results just as well.  Each winemaker is encouraged to try the process that works best for them and their particular cellars.  This process does have the quality of shorter chilling time and reduced utility bills plus faster turn around time for a specific wine – should those goals be desired.  Recall non grape fruit based wines may perform differently.

*  The 3.65 Bifurcation term was not located in any research literature by the author and it is a term the author has used to describe this phenomenon in his cellar work.

Holiday Email Best Practices

woman towards the mail icon

By: Susan DeMatei, President of WineGlass Marketing

If you’re like most, you have a holiday calendar crammed full of events, sales, shipments, and recipes ready to communicate to your mailing list. Email marketing is a staple among wineries trying to communicate to wine clubs, provide holiday offers and reach new customers. Follow some of these tips below to make sure your holiday sales are bright.

There are three major influences on the success of an email campaign. From most important to least, they are List, Offer, and Creative.

List: Take some time each year in September and October to perform some basic data hygiene. An intern or consultant can help you here with a well-organized couple-week project.

• Clean up duplicates and merge duplicate records from the tasting room, wine club, website, MailChimp, or other (sales_email_marketing) databases. When doing so, carefully identify the correct master record and fold all the visit history, source, and transactional data under that master customer record.

• Append data with addresses, emails, and phone numbers.  There are several resources to do this simply through excel for pennies a record.

• Remove bounces and anyone who has opted out of any communications over the course of the year.

• Add in any stray lists – like that tasting you did at the event in Vegas in July or the Winemaker’s alma matter list that wants to hear about his wines. And make sure you notate a source on all lists so you can refer back to see what programs procured good, qualified leads.

• Once you have a clean list, then take some time and segment and the time your communications thoughtfully – don’t just send every offer and update to everyone. Perhaps the October Wine Club should not get the Thanksgiving sales to email so close to their Club Shipment email alerts, but instead a printed insert in their club shipment.  If you have the transactional data, you’ll want to target email-marketing messages based on behaviors such as past purchases, tasting note downloads, visits to the winery, links clicked, or other captured actions.

Offer: Only after you’re happy with your lists should you focus on the offer.  Based on your steps above, now consider what sales message will incite the best response to your segmented list?

• What did they respond to in the past? Did you have any past learnings to guide you on what resonated, or failed, previously? If not, perhaps your database is big enough to split and test. For instance, if you suspect that shipping offers will be popular this season, should you give a % off shipping, shipping included, or shipping for $1? And at what volume: 6 bottles? A case? These are things you can test with an email and then do a follow-up email to the entire database of the winner

• What are your goals? What wines do you need to move, and what costs or discounts are appropriate for your other channels? Make sure the wine you just sent to the Wine Club at 20% off isn’t in a holiday sale email a week earlier for 25% off. (A calendar is beneficial this time of year to keep the tasting room, website team, social media, and emails all in synch.)

• Use tracking tools and analytics to determine which emails and corresponding landing pages are the most successful in generating sales.

• Know (or set) Click-Through and Open Rate goals. According to the 2020 WGM Wine Industry Email Benchmark Study (which you can download on our website), email Open Rates for wineries average 24.66%, and Click-Through Rates for wineries average 5.08%.

Creative: The design of your email is essential. There are two reasons email design should follow specific layout rules. First, as of August 2021, mobile phones account for 41.6% of email opens (Litmus). Second, most email service providers, such as Outlook and Gmail, now block images by default. If your graphics contain text including important information, such as the offer or wine details, make sure you repeat the information in the text.

•  Email marketing is just another branding opportunity. Place your logo in the upper left-hand corner or centered as a header of the email.

•  Include navigation like on your website. You don’t have to have every page from your site, but the significant sections help customers engage with you online and create familiarity with your website.

•  Make sure your email is no more than 500-650 pixels wide. Any more than that means your reader will be scrolling horizontally.

•  Keep text to less than 250 words and have frequent links to deeper levels of content or more information on your website.

•  Keep it clutter-free. The less clutter you have in your email, the better. Don’t use more than two typefaces.

•  Keep your main message and call to action (CTA) at the top of the email. It’s ok to scroll in an email and have it laid out vertically but keep your primary message upfront.

•  Create an engaging, concise subject line. A relevant offer that creates a sense of urgency will be your best bet. Your subject line needs to have an incentive for your audience to open the email.

•  While your site may have a lot going on, your email message should be singular in focus. Make sure the message and the requested action are clear. Instead of splitting up readers’ attention, focus on driving home a single-minded message.

•  The landing pages that prospects reach after clicking through are just as important as the initial email. Your landing page should match the email in terms of headline, copy, and content. Use similar colors, fonts, and overall design to keep your customer on the right track and avoid confusion.

•  Make sure your CTA from the email has a connection to the CTA on your landing page. Again, keep the call to action above the fold and relevant to your marketing message.

  Having an effective email marketing campaign is about being intelligent and concise. Focus on the list first, differentiate yourself with targeted segmentation, and then deliver a tested sales message with clean creativity, and your Q4 emails are destined to be a blast!

Tips for Helping Increase Bookings in Off-Peak Wedding Season

wedding couple standing in a vineyard

The months of January, February and March are typically considered “off-peak season” in the wedding industry and tend to be slower months. Getting more bookings in these months require a different strategy than peak season as well as thoughtful planning. Let’s look at some strategies to consider to help increase your business in the off season.

5 Tips to Booking in the Off-season

1.   Offer Off-Season Rates: There is a market for off-season weddings, you may just need to work smarter to reach it. Find budget-conscious couples through online target marketing (Social Media ads) and offer discounts for your slower months. Create a list of keywords that couples may use to search online for and include the words in your ad strategy. Some keywords may include affordable weddings, wedding discounts, wedding deals, wedding offers, wedding venue discounts, off-season wedding deals, off-peak wedding season discounts, etc.

2.   Promote Early: As you know, it takes time to plan a wedding. It makes sense to, start advertising your off-peak season discounts at least a year in advance. This gives couples looking for affordable alternatives a chance to decide if having a wedding in the off season is right for them.  An affordable way to advertise is through your blog and a special section on your website.

3.   Target Last-Minute Weddings: Most couples plan their weddings, at the very least, 6-months in advance. However, there are still couples who plan a wedding in less time. This can work to your advantage in the off-peak season. You may not have to offer the deepest discount to win this business because these couples are motivated to tie the knot. Again, the best way to find these couples is through targeted ads. Keywords that may appeal to these couples are last-minute wedding deals, last-minute wedding offers, booking wedding venues last minute, wedding planning in a short time, etc.

4.   Partner with Vendors to Offer Exclusive      Deals: The broader your network with local wedding industry professionals and vendors, the better positioned you may be for the off-season months. You may not be a couple’s first stop in their wedding planning – think bridal shops and jewelers. Consider exchanging voucher coupons with these vendors to promote each other’s businesses. In addition, if you partner with other local wedding vendors, you may be able to come up with an attractive package to offer budget-conscious couples and couples who are planning their weddings in a short amount of time.

5.   Highlight the Advantages of an Off-Season Wedding: Engaged couples have a variety of concerns about booking in the off-season. Concerns they likely wouldn’t have to face in the peak season, mainly weather related. By highlighting the advantages of an off-season wedding to the couple, they may decide the risk is worth it. Here are some points to highlight:

•    Saving money with discounts.

•    Creativity with the theme and photos. Winter-themed weddings are unique and memorable because most weddings take place in the summer months. Their photos will be stunning with the natural beauty of the season and choice of winter fashion for outdoor photos (beautiful coats and capes for the wedding party).

•    Winter-themed décor and food choices that wouldn’t be offered in the summer months. For example:

      a. crystal icicles, shimmery linens and silver and gold accents lend a magical aura

      b. warm desserts such as death-by-chocolate, mini rum cakes, warm cobbler and crumbles

      c. hearty comfort food with creamy soup, whipped potatoes and roasted vegetables

      d. seasonal drinks like hot chocolate, hot apple cider, coffee, cappuccino, hot buttered rum, spiced wine, and eggnog

•    Increased attendance. People are busy in the warmer months and are more likely to decline invitations for other commitments. In addition, out-of-town guests, can experience lower airfare in the off-season.

•    Highlight the ways you prepare your venue for colder months, including your assurance of a comfortable, warm atmosphere (like a fireplace), cleared parking lot and walkways of snow and ice, a large, accommodating coat room, hand-warming towels in the restrooms, a backup generator, and many other ways you take care special care in the off-season to provide the best service possible.

  We hope these tips will help you attract more clients to your venue during the off season who should also think about event insurance.

Don’t “Blow Off” Cybersecurity

Martin Luther, the famous German theologian and religious reformer, is credited with saying “Beer is made by men, wine by God.” Had he lived another 475 years, he likely would have added that “Cybercrime is made by the Devil.”  And, he wouldn’t have been too far off.

  Cybercrime is insidious: It knows no borders and as we’ve seen, knows no bounds. In fact, a report from Cybersecurity Ventures predicted that the global cost of cybercrime will reach $6 trillion USD this year. According to the 2019 Cost of Cybercrime study by Accenture and the Ponemon Institute, the average cost of cybercrime to a U.S. organization was $13 million — a significant sum. And, a report from my own company eSentire found that cybercriminals netted more than $45 million in the first four months of 2021 alone. But before you start thinking that means cybercriminals only go after the big guys, consider the fact that it’s small and medium-sized businesses (SMB) that are the primary targets for data breaches (Data Breach Investigation Report, Verizon 2020).

  To be sure, there are threat actors that are out to make trouble, whether it’s disrupting critical fuel pipelines or, like the modern-day equivalent of sleeper agents, quietly accessing classified systems to gather top-secret information or cripple it at a later date. However, what most companies encounter comes as the result of unadulterated greed from a run-of-the-mill cyber crook. Just like your average street criminal, these people attack businesses because that’s where the money is. And like it or not, SMBs, such as family-run wineries and vineyards, make for low-hanging fruit. Cyber attacks on the wine, spirits and beer industry have ramped up in the past year including hits on Brown-Forman, E & J Gallo Winery, Molson Coors, and the Campari Group.

The Earth Is Mine. (What About Your Network?)

  On the one hand, it’s a brave new world for the farming and production aspects of winemaking, thanks to automation advances. But on the other hand, a great deal of manual labor is involved, and despite advances, the wine industry is still considered very much old-school, lagging behind other industries when it comes to the use of technology.

  When you consider the production process from grape to glass, some of the greatest risk of cyber exposure lies on the farming side. Growing the perfect grape comes with a lot of moving parts, and like other production businesses, enterprise resource planning (ERP) systems are in place to track a variety of processes, from what pesticide was applied on which date,  to the costs involved, etc. Whereas how these things are tracked will vary from vineyard to vineyard, the common denominator is that in most cases the people interacting with these systems are predominantly field workers who might not be the most tech-savvy. Add to this the fact that many front-line remote systems are loosely managed and run on personal field laptops or mobile devices, and you have an ideal attack vector.

  Regardless of whether you are operating a small, family-run vineyard or have a large-scale wine operation, you face an even greater risk each time you sit down at your desk. The vast majority of cyberattacks begin with malware, typically embedded in an attachment sent with a seemingly innocuous email. Maybe it’s an invoice from a distributor you work with, maybe it’s your bookkeeper asking you to review a document, or maybe it’s a complete stranger, hoping you’ll slip up, open his attachment, and launch a malware script that will encrypt your data until you give in to his demands.

  While unsecured computer systems and mobile devices are common attack vectors, it’s safe to assume that as your operation grows, so too does your attack surface. Now wine operations have barcoded, inventory-tracking devices that are used on a remote workflow in the field. That information is fed into a central ERP system that’s tied to another automation system, and so on throughout the production process, as tank temperatures and acidity levels are monitored. Then, too, consider the controls that regulate humidity levels inside a facility or the transfer of wine from tank to tank. Any and all of these systems can be tampered with and if they are, it can negatively affect the end product and your business.

Data, Decanted

  Outside the confines of your vineyard or winery lie even further risks. Supply chains are attractive targets not just for the information they hold but the damage they can inflict if disrupted. Distributors, especially smaller ones, often track depletions manually and share updates via email. Consider the example of a small warehouse in Kansas City that might have 20 pallets of your wine and little to no security solutions in place and then consider how quickly a threat vector could spread via a spreadsheet attachment.

  On the retail side of wine operations, both on- and off-premise operations, offer up other strike zones. Each of these channels has its own supply and inventory management systems that track activity all the way out to individual shops, bars, and restaurants, which again, may or may not have the strongest security posture.

  Nor can you overlook the direct-to-consumer aspect. Customer relationship management(CRM) systems that are used to manage your wine club or market tasting events hold a wealth of personal information, not to mention credit card numbers. They’re gold mines for those looking to sell that information on the Dark Web for a tidy profit and scarily enough, you might never know you’ve been compromised.

Just Enough Rain to Stress the Vine: A walk in the cloud(s)

  In the face of myriad risk and attack vectors, it’s tempting to take the path of least resistance, and send up a prayer that you’ll be among the lucky ones to not suffer a cyber breach. But in today’s climate, that’s risking a lot more than bottle shock. Companies today, regardless of their size or industry, need to assume that it’s not a matter of if they will be targeted by cyber crime, but when. Depending on your size and budget, running a full-scale Security Operations Center might not be in the cards, but there are steps you should be taking to protect your business today and in the future:

●    Suspicious emails should trigger the same reaction as a wine that’s corked. Avoid it at all costs. Phishing emails are a popular attack vector, and unless you know what to look for (and how), you are putting yourself and your company at risk each and every day. Educate your staff on what to look for and make sure that whatever training they receive is specific to the vineyard/wine industry. People like to think they won’t fall for the “Congratulations! You’re a winner” emails, but are they prepared to investigate those emails from your attorney or best vendor? Additionally, you should ensure that your department systems are segmented, preferably using the principles of Zero Trust. That way, if one person accidentally opens a malicious email, they won’t be granting a hacker access to the whole system.

●    Maintain Security Hygiene: Network systems need to be maintained and cared for just as you would oak barrels. Security  hygiene is a critical component of cybersecurity and at the very least should include:

1.   Regularly patch and update your software You’d be surprised at the number of breaches that could have been avoided simply by keeping software systems patched and up-to-date. It’s estimated that a third of all data breaches come as a result of unpatched vulnerabilities when patches were available. (Looking at you, Equifax).

2.   Two-Factor Authentication Is a MUST . Make sure to implement two-factor authentication around all of your company’s key software applications and systems, providing an additional layer of security. Never, ever reuse passwords across accounts or devices, and if your budget allows, implement solutions that employ a Software Defined Perimeter (SDP) approach. Be aware, however, that while these solutions offer advanced security, because they are more complex they are costlier; plus, there are the added costs associated with hiring staff who have the proper expertise to manage them.

3.   Operate on a need-to-know-basis. In general, it’s a good idea to limit the amount of network access your employees have — compromised accounts can be used to create shadow employee accounts which in turn can be used to move around a network. It’s especially important that top-level executives and owners aren’t given the full set of keys to the kingdom just because they’re the boss. Senior-level employees and owners are prime targets for cybercriminals looking for ways to infiltrate a system and move around with impunity. Someone might ask why your front-desk staff is nosing around a payroll system, but no one will question the boss.

4.   Virtual private networks (VPN) are more than a good idea. They provide secure and encrypted connections between systems (files shares, email servers, etc.) and ensure that your communications can’t be intercepted.

5.   Lock down your operational technology (OT) systems and ensure that they are not left internet-facing.

●   Automation technology is complicated and protecting it, even more so. You can’t assume that everyone further down the supply chain is taking a serious approach to cybersecurity or even knows where to start. It’s incumbent on you to protect your business, so talk to the experts. Be sure to talk with your insurance providers, legal team and other key vendors to ensure you have a plan in place for when the inevitable happens.

Something to Think About

  Too often, companies fail to adequately protect themselves against cybercrime, because they are laboring under a trifecta of misconceptions:

●   “We’re not a bank or even a household brand name so we aren’t a target.” This is a prime example of absolutist thinking and the harm it can cause. To the thief, even the poorest person has something worth stealing.

●   “We could never defend ourselves against massive ransomware gangs and state-sponsored actors so why even try?” When it comes to the average cybercriminal, Thomas Crowne they are not. That said, there’s no reason to stand up when the bullets are flying. By carrying out basic cyber protections you can reduce your risk by up to 80 percent.

●   “We never saw it coming.” In the world of cybersecurity, by the time you see the red flag, it’s too late. Heed the little signs. They won’t all pan out to be cyber attacks, but when things go bump in the cybernight, it usually means there’s a monster there. It just hasn’t struck yet.

  The wine industry has a long and storied history and holds an important place in culture and daily life. From small vineyards to wine conglomerates, there are financial gains to be made for the hacker looking to grow his ill-gotten gains. By following some basic steps, you can ensure that cyber criminals are the only ones claiming sour grapes.
