Wines of Argentina

Bonnie and Clyde. Jekyll and Hyde. Bread and butter. Salt and pepper. Some things are so synonymous with something else that it’s almost impossible to mention one without the other. In the oenophilic world, it’s hard to mention Argentina without mentioning (or at least thinking about) malbec.

  Personally, I can’t think of any other country whose vinous history is so inexorably linked to a single grape variety. (Okay, New Zealand and sauvignon blanc; I’ll give you that.) So important is malbec to Argentina’s wine industry that it accounts for almost 40 percent of all Argentine wine sold. And each year, April 17 is celebrated as Malbec World Day, a global initiative created by Wines Of Argentina (the organization responsible for, among other things, promoting the country’s wines) that seeks to position Argentine malbec as one of the most prominent varieties in the world. 

  First introduced in the mid-19th century, malbec vineyards in Argentina continue to expand, with close to 110,000 acres in the ground today.

When I visited Argentina a few years ago, I got a first-hand look at what progressive winemakers were doing in terms of technological improvements, vineyard site selection and viticultural and vinicultural practices. In other words, serious winemaking practices by dedicated, quality-oriented vintners. It wasn’t always like this.

“Until the late 1980s, Argentina was probably the worst wine producing country in the world,” admitted California vintner Paul Hobbs during an interview (and being careful not to mince words).” Having established a number of successful partnerships in California, Hobbs set out to prove to himself and the rest of the world that, when treated with respect, Argentine malbec could yield wines as good (and in the case of those from his Argentinian venture Viña Cabos, often better) than the best any country has to offer. The reason for the poor quality was simple: nobody really wanted to make anything better.

“Wine was strictly for consuming, not selling in bottle,” Hobbs maintained, “and for the most part it was all oxidized. There was really no concept of how to make good wine.”

  Thanks in large part to the pioneering efforts of local winemaker Nicolás Catena, whose epiphany came while in Napa Valley (and who took inspiration from Robert Mondavi’s contribution to the wine scene there), the scene began to change. Hobbs experienced a similar epiphany on a road trip from Santiago, Chile, to Mendoza, Argentina, at about the same time that Argentina’s winemakers were starting to get serious.

  “I saw what was possible,” he recounted. “There was a strong culture of wine, but a lack of practical knowledge. The vineyards were poorly farmed. The vines, especially for malbec, were over-irrigated, and in an effort to mitigate the threat of hail, trained far too low to the ground.”

  However, he saw a strong work ethic in the people and the potential in the land to support a world-class wine industry. “What I saw,” he says, “was an unpainted canvas.” Transforming this canvas into a vinous Rembrandt has been, essentially, what Hobbs has been able to do.

  While controlling yields and bringing more modern winemaking equipment and techniques to bear has certainly led to the continuing improvement in the overall quality of Argentina’s wines, perhaps the most significant factor behind the positive developments in the country’s wine industry hasn’t been so much about how to treat the fruit, but rather, where to plant the fruit. And as winemakers began to explore grape varieties beyond malbec, it has become apparent that they behave quite differently depending on where they are planted.

  “In our case [site selection] is the most important thing,” admitted Germán di Césare, winemaker at Bodega Trivento. “The vineyard selection is critical because it is where the whole process begins. Each site provides different characteristics to the wine, so we plant according to the wine we want to produce.”

  I also asked Gonzalo Bertelsen, general manager and chief winemaker at Mendoza’s Finca el Origen, who elaborated further:

  “Every vineyard suits a particular vine and wine,” he told me. “And even within the same vineyard, we see big differences in how the vines behave depending on weather, grape variety, soil, rootstock, irrigation, canopy management, hang time, and so on.” He notes that merlot wines made from fruit grown in the eastern part of Mendoza are typically very different than those sourced from the region’s western part, which is 600 meters higher.”

  In fact, elevation has turned out to be one of the most critical considerations in the critical process of vineyard location. The vines for Hobbs Viña Cobos wines are planted in numerous high-elevation vineyards throughout the Uco Valley and the department of Luján de Cuyo. The soils in these vineyards tend to be poor in organic material and blessed with deep layers of rock and mineral, as well as good drainage, resulting in fruit with concentration, structure and complexity.

  “High-altitude vineyards provide a wide temperature range,” Di Césare confirmed, going on to explain that “low temperatures at night and higher temperatures during the day make for perfect conditions for the harvesting of perfectly ripened fruit.” 

  As alluded to a few paragraphs back, malbec might be the preferred weapon in most Argentinian winemakers’ arsenal. Still, plenty of other red and white varieties are being used with generally favorable results.

  “We are sure that we can show there is much more Argentina can offer than just malbec,” Julián Iñarra Iraegui, commercial director for Proemio wines, told me. “The region we are in, Maipú, from my understanding, is the best region for growing cabernet sauvignon. We also make wines from petit verdot, syrah, grenache and cabernet franc.” Iraegui said that Proemio is looking to “deconstruct and reconstruct” classic French blends to craft wines that are both single varietal expressions and blends featuring those same grapes. He stated the winery’s style is “more French.”

  “We avoid over-extraction and the heavy use of oak,” he said. “We import our barrels from France, and we are also using some barrels that are made from tree branches rather than trunks. We are the first winery to use these in Argentina.”

  Tasting through a range of Proemio wines with Iraegui, I was impressed by the complexity, poise 

and refinement of the wines crafted by French-thinking (though of Italian descent) Marcelo Bocardo. “Marcelo loves blends,” Iraegui revealed when asked whether malbec might be better as part of a blend than as a single varietal.

  Though the winery makes a couple of 100 percent malbec wines, Iraegui said that the winery “loves cabernets.”

  Indeed, the Proemio cabernet sauvignon “Reserve” 2016, with its aromas of tobacco, black currant, mint, pepper and dark plum, more than adequately showed the potential of this grape variety. Juicy and dense, it was nonetheless perfectly balanced and elegant, with a hint of spice intermingling with the chewy cassis fruit.

  Just as Argentina isn’t solely about malbec, it’s also not strictly about vino tinto. Most of the main international white varietals (chardonnay, sauvignon blanc, viognier, semillon, chenin blanc and muscat) have taken root in the country’s soil. But the most interesting white variety is something unique to Argentina.

  A cross between the Listán Prieto and Muscat of Alexandria varieties, Torrontés (or more precisely, Torrontés Riojano (there are three variations of the grape), gives white wines with intense aromatics and lively flavors (very much like a dry muscat…not surprisingly).

  “Torrontés is a magnificent variety, with a high oenological value and [versatility] to obtain different wine types,” Susana Balbo of the Eponymous Winery explained to me. “In our case, we produce low-alcohol wines, natural sweet wines, dry wines, barrel fermented wines and late harvest wines from Torrontés grapes. Due to its great aromatic richness and its adaptability to diverse types of climate, Torrontés provides an interesting range of aromas that makes each wine unique.”

  I’m not sure if the situation is different in the United States, but in Canada, the wines of Argentina have generally been relegated to the “cheap and cheerful” category, which isn’t really fair and certainly doesn’t allow consumers to experience what the country really has to offer, wine-wise. Sure, you can get perfectly acceptable wines for under $20 (that’s CDN, so apply the current conversion factor for USD). But I highly recommend springing for something a bit more upmarket. You’ll likely find that the flavor profile will increase dramatically even though the price will still be below that of wines from more recognized countries and regions.

Improving Late Season Spray Coverage

By: Kirk Williams, Lecturer-kirk.w.williams@ttu.edu

Lots of time is spent selecting products to control late season pests but how much time do we spend fine tuning our sprayer for these applications?  Late season spray applications can be critical in delivering clean fruit and keeping a functioning canopy post-harvest especially in areas where rainfall is common during the growing season.   Effective late season spray applications can be more difficult to achieve due to a larger and denser canopy.   

  Understanding spray coverage requires that you understand how droplets are created.  Hydraulic spray nozzles create a wide range of droplet sizes.   These droplets are measured in microns with droplets from 150 to 300 microns considered the most effective at being deposited in grapevine canopies when used with air blast sprayers.   Larger droplet sizes may bounce or roll off leaves while very fine droplets are more prone to drift.  Theoretical spray coverage based on average droplet diameter is 30% for 100-micron droplets, 15% for 200-micron droplets and 10.1% for 3300-microndroplets.  A greater number of spray droplets per unit area will have a higher probability of controlling the target pest. 

  Evaluating your spray coverage at any time of the season is critical but as the canopy gets larger and denser it becomes even more critical.  One way to evaluate spray coverage that requires minimal effort is with water sensitive cards placed in critical parts of the canopy such as the fruiting zone.  When spray droplets land on the water sensitive card, the card turns blue.   Water sensitive cards should be used when the humidity is below 80% and the canopy is dry because any moisture will turn them blue.  The water sensitive cards will react to moisture in your fingers, so be sure to wear waterproof gloves when placing the cards in the canopy.

  Spray coverage standards do not exist for control of specific insects or diseases.  Recommendations from Syngenta, one of the manufacturers of water sensitive cards, recommend 20-30 droplets/cm2 for insecticides and 50–70 droplets/cm2 for fungicide applications to provide satisfactory results.  A square centimeter is about 1/6 of a square inch.  The water-sensitive cards can be visually assessed for coverage through the provided viewing cards.  Visual observation can help you understand coverage and see droplet size, but it does not give you any numerical information that can be used to improve spray coverage.

  Water sensitive cards can be scanned and analyzed by computer programs such as the USDA’s ARS DepositScan.  The program gives you percentage coverage and deposits per cm2 .  While very accurate, this is a slow process and not well suited for the quick results needed for adjusting sprayers in the field. 

  Apps are now available that will quickly and easily analyze water sensitive cards for coverage.  SnapCard is an app that is available only for Android smart devices.  SmartSpray, is available for both iOS and Android smart devices. Developed for use in field crops such as strawberries, the spray card analysis portion of the SmartSpray app is a useful tool for analyzing percent coverage as well as accounting for small and large spray droplets.

grapevine canopy was sprayed (Figure 1) and analyzed for spray coverage using the SmartSpray app (Figure 2).  The analysis from the SmartSpray app came back with 35% coverage with small droplets and 3% coverage with large droplets.  This quick analysis shows very good coverage for this application and within the range of what we would consider good coverage.   The SmartSpray app does not report droplets per cm2  so to confirm that our coverage number matched up to droplet number the same card analyzed by DepositScan. DepositScan reported 125 droplets per cm2 which is more than the target 50-70 droplets cm2 for fungicide applications.  The SmartSpray app can be a new tool to quickly analyze your spray coverage in the field when using water sensitive cards. 

Mid Season Spray Coverage Smartspray app

(Figure 2)  

If your water sensitive cards indicate that you are not getting good coverage there are several ways to adjust your sprayer to improve coverage. 

Increase Air Flow

  Lower fan speeds may have been used in the early part of the growing season to reduce drift.  In the later part of the season many sprayers can be adjusted to increase fan speed.   For increased late season spray coverage in dense canopies, increasing the air flow may be the easiest way to improve coverage.   Deflectors that focus the air flow more horizontally or on the fruiting zone may also improve coverage.  Keep in mind that excessive air flow can increase drift by pushing the spray droplets past the canopy target.   Be sure to confirm coverage using water sensitive cards after increasing airflow. 

Change Sprayer Output

  Increasing sprayer output by decreasing forward speed or by using larger nozzles can improve spray coverage but it does require that you recalibrate your sprayer due to these changes.   A higher volume can improve coverage if your droplet coverage is low based on your water card analysis.  The target is still to have many small droplets in the canopy.   Too much volume can run spray droplets together and cause spray run off of the leaves. 

  There are many action items to do in a vineyard to keep it productive and produce high quality grapes.  Taking time during the season to check your sprayer coverage and then adjust as needed is one of those critical items.  Larger and denser canopies may require that you take the time to look at your coverage later in the season as well.  New and old tools are there to assist you in evaluating and improving your spray coverage.

Top 5 Vineyard Equipment Companies & What They Offer

man riding a crop machine

By: Alyssa L. Ochs

Choosing the right equipment is one of the most important decisions a vineyard owner will ever make, especially since heavy pieces of machinery are significant investments built to last for many years. Some companies that cater to the needs of vineyards specialize in just certain, niche types of equipment, while others are one-stop shops that offer nearly everything required to grow and harvest grapes for making wine.

  To help you narrow your options, here are five top companies offering vineyard equipment and what makes them stand out as suppliers in this industry.

Gearmore, Inc.: 24 Implements to Make Your Vineyard More Productive

  Gearmore, Inc. is an employee-owned business specializing in implements for the agricultural and light construction industries. Based in Chino, California, Gearmore has been in business for approximately 60 years and provides quality implements through servicing tractor dealers.

  Robert Giersbach, the marketing manager for Gearmore, told The Grapevine Magazine, “We have always placed a priority on vineyard implements due to the large acreage on the west coast. There are about 900,000 acres of vineyards in California, which includes table, raisin and the largest being 615,000 acres of wine grapes.”

  Since growing grapes requires many types of machinery, Gearmore offers 24 unique implements for vineyards in varying widths and capacities. These include vine trimmers, leaf removers, pre-pruners and multiple pieces of spraying equipment. Gearmore also offers compost spreaders, rotary tillers, soil conditioners, weeders, cultivators and numerous other options relevant to essential vineyard work.

  “The California vineyards are planted in row spacings from four to 12 feet, with six- and eight- foot rows now being the most popular. The coastal vines are using mainly trellis with vertical shoot positions, but the hotter Central Valley requires a trellis system, such as California sprawl, double cross arms or quad.”

Kingsburg Cultivator, Inc.: Durable Products with Replacement Parts

  Kingsburg Cultivator, Inc. was established near the small, rural town of Kingsburg, California in the 1950s as an agricultural equipment manufacturing and repair company. Chuck Norris from Kingsburg Cultivator said that his company offers a wide range of equipment and solutions for all seasons.

  “We specialize in berm management solutions, which include our products made in the central valley of California,” Norris said. “We also import equipment out of Italy known as Orizzonti. Within our berm management division, we have mowers, blades, discs, sweeps, tillers, paddles and string weeders. We have single-sided and double-sided frames that we can mount in either the front or rear front or rear of the tractor based on the needs of the customer.”

  KCI’s pruning division offers various pre-pruning solutions available in both single and double-sided frames. These options include sickle bars, disc pruners and high-speed skirters with many adjusting configurations available year-round.

  “Our Orizzonti line offers different length shredders as well,” Norris said. “You can interchange flail blades or hammers in any of the shredders we offer. Our spreader division consists of vineyard models and has interchangeable attachments for different applications. We offer a KCM 58 and KCM512 with bander and spinner attachments. The spreader dimensions are five inches wide by eight inches long and five inches wide by 12 inches long. The banding configuration comes in five-, six- and eight-inch lengths. Our supersealed bander allows little to no loss in product.”

  KCI has been a manufacturer of vineyard equipment for over 65 years, starting with a belt drive skirter that operated off the crankshaft of the tractor. Since then, the company has stood out because of the quality of its products, outstanding service and replacement parts on hand.

  “Since the beginning of time, we at KCI have had a high expectation of product quality and durability, and we stand behind our products,” Norris said. “Customer and field service also is what sets us apart from other similar businesses. With our experienced office and shop staff, we can help our customers timely and efficiently. KCI makes sure to prepare and have replacement parts on the shelf ready for when our customers are in need. We understand that downtime is a very costly expense and always keep the customers’ best interests in mind. With us being a fabrication shop, in some cases, we can even build parts for equipment other than ours if our customer isn’t able to find the part needed. We also do field repairs of our equipment for our customers with service trucks and skilled technicians if we can’t diagnose and troubleshoot the problem over the phone.”

New Holland Agriculture: Grape Harvesters & Tractors Just for Vineyards

  New Holland Agriculture, a subsidiary of CNH Industrial, brings over 125 years of experience to the industry and serves vineyards with specialty tractors and grape harvesters. Tanner Cady, a viticulture marketing specialist for specialty tractors and harvesters at the company, told The Grapevine that New Holland Agriculture’s specialty tractors come in various ranges for horsepower, width, height and traction style, specifically the T4F/V, T3F and TK4 models.

  “Wine grapes range in row spacings from 3.5 feet to 11 feet,” Cady said. “We have three different tractor widths – 42 inches (T4V), 55 inches (T3F) and 63 inches (T4F) –  to fit those applications. In most scenarios, height is not a problem like it is for table grapes. And depending on the size of the operation, you can choose between 80, 90, 100 or 110 horsepower for the T4F/V and 60, 70 and 80 horsepower for the T3F.

  New Holland has a tractor built for vineyards planted on steep hillsides, too, the TK4 Crawler.

  “This tractor is available in different horsepowers, widths and heights,” Cady said. “Depending on producers’ applications, they may want one with or without a cab, one that is 46 inches wide or 70 inches wide or lastly, one with only 80 horsepower versus 100 horsepower. The T3F also has a very low center of gravity that makes it useful on hillsides, too.”

  New Holland Agriculture’s grape harvesters are available for row widths of 3.5, 4.5, 5.5 and 7.5 feet. The horsepower ranges are from 128 to 182, and three different cleaning styles are available: straight to tank, destemmer and Opti-Grape.

  “Straight to tank is our most basic way of removing mog,” Cady said. “This is made up of two to four fans. Those fans are standard with all other forms of cleaning. Destemmer is our mid-range form of cleaning. It acts as a sieve while forcing grapes to fall through a mesh belt. It then collects the leaves, wood and anything else that isn’t a grape to continue down the belt and over the back of the machine onto the ground. While destemming, it also breaks up the clusters and collects the rakis while directing the grapes to the hopper. Opti-Grape is our premium sorter. This is done with what we call an ‘Air Knife.’ It uses pressurized air to discharge everything other than grapes out the side of the machine, leaving a nearly perfect sample in the hopper that is ready for the winery and requires no additional sorting at the winery.”

  New Holland is unique in the industry because it is the only manufacturer to make grape harvesters and tractors under the same umbrella.

  “Also, both our harvesters and tractors run FPT engines,” Cady said.” “This is particularly important when it comes to harvesters. Other grape harvester manufacturers run a third-party engine that requires separate technicians from those who will service the harvester itself — one unit and two technicians for servicing. With the New Holland grape harvesters, our technicians are trained on both the engine and the harvesting mechanisms, meaning we can service both in the same visit.”

Kubota Tractor Corp.: Reliable Tractors and a Knowledgeable Dealer Network

  Kubota Tractor Corp. introduced its first tractor to the U.S. in 1969 and has expanded to offer many products today, such as utility vehicles, lawn mowers, construction equipment, agriculture tractors and hay equipment. Erik Lisitza, Kubota’s product manager for specialty tractors, told The Grapevine that his company offers various power units and implements for the vineyard market.

  “Kubota’s M Narrow Series tractors, which includes the M4N and M5N, are offered in both open station and cab models with three horsepower ranges and multiple transmission options, in addition to the M5N Power Krawler Narrow CAB half-track model,” Lisitza said. “Our implements for mowing, seeding and tillage are offered through our Land Pride brand.”

  Kubota introduced its second-generation M5 Narrow Series at the exhibitor grounds at the World Ag Expo in February 2023, which includes two new models, the M5N-112 and the M5N-092. The durable workhorse tractor users have come to rely upon remains at the core of these latest models. However, updated comfort features and visibility enhancements are now available while using them among the rows and vines.

  “Our consistent offering and being known for our simple and reliable tractors is what makes Kubota stand out as a provider of vineyard equipment,” Lisitza said. “Our knowledgeable dealer network works and lives where the vineyards are, and they know their customers and the specific needs of their industry.”

Jacto Inc.: A Sprayer Specialist with a Global Presence

  Headquartered in Tualatin, Oregon, Jacto Inc. offers high-tech products and innovative solutions for the agricultural industry and has a presence in over 100 countries. Jacto has a history that dates back over 75 years and has plants and offices in Argentina, Brazil, Thailand and Mexico.

  Walter Mosquini, Jacto’s international sales manager, told The Grapevine that the primary sprayers that his company sells to vineyards are the airblast sprayers. Jacto offers 13 different models of airblast sprayers ranging from 50 gallons to 1,000 gallons. 

  “We also offer a mini-tower kit for four different models to provide even better coverage to the crop. The other type of sprayer the vineyard market buys from Jacto is a hooded herbicide sprayer to spray weeds between the rows while protecting the crops from chemical drift.”

  Mosquini said that Jacto is unique as a vineyard equipment provider because of its global presence and long history in the industry.

  “We offer many models of sprayers, from hobby vineyard operators to extensive corporate vineyards,” he said. “Our sprayers are built to withstand the heavy use found in commercial farming. Our Arbus 200 sprayer can be operated with an 18-horsepower tractor, keeping the tractor and sprayer cost at a minimum.”

Choosing Equipment for Your Vineyard

  Each of these companies has something unique to offer vineyards, and the industry leaders who work for them can provide helpful advice for choosing new equipment to grow grapes.

  Giersbach from Gearmore said, “When asked by growers what equipment they may need, we ask about the row width, tractor model and what operation and outcome they hope to achieve. Yet established growers usually know exactly what they need and do not require our input.”

  Cady from New Holland Agriculture recommends buying equipment that does not run a Diesel Particulate Filter (DPF).

  “You will only find this with New Holland equipment; we maintain a low carbon footprint without the need for a DPF,” Cady said. “Also, consider your acreage, terrain, row spacing and yield when choosing a harvester or tractor. Those play considerable factors in the make-up of the equipment a producer will need to purchase.”

  Mosquini from Jacto shared his company’s sprayer selection guide with The Grapevine, a guide designed to help vineyards determine the model of sprayer that will work best for their needs. The guide addresses 12 essential factors to consider, starting with the type of crop, the number of acres to be sprayed, the typical galloon sprayed per acre and pump capacity. Tractor speed, row spacing, crop height, turning area and crop density are other factors to consider.

  Lisitza from Kubota advises vineyard owners looking to buy new equipment to talk with a local dealer for the best advice before making a major purchase.

  “They know our equipment, and they know your business and the vineyard market. Their knowledge can help you get into the right piece of equipment for your operation,” he said.

  Norris from KCI advises prospective customers to do their homework and ensure their fields are set up properly to run the equipment they are trying to purchase.

  “Make sure to include photos, videos, row spacings, type of field and irrigation techniques to ensure the mechanized equipment won’t damage or cause more issues than your current practices,” Norris said. “If your field is not set up correctly but you want to move to more mechanized techniques, make changes to your field before the purchase. Also, make sure the company supports your equipment with service and parts availability. The sense of assurance when your equipment malfunctions or is damaged and parts are a call away is priceless. Reliability is very important for the product you plan to buy as well. Do research into the company producing the machine of interest. This can include looking at reviews and comments on Google, asking current owners of the machine and going to see the machine run in the field for yourself.”

The Application of Tissue Culture for Grapevine Disease Elimination

By: Judit Monis, Ph.D. – Vineyard and Plant Health Consultant

My experience working with tissue culture techniques on grapevine dates from my first job (after my post-doctoral fellowship at UC Berkeley) at Agritope, Inc., a biotechnology company that was based in Oregon.  The company owned a grapevine nursery and I was hired to start a disease testing and eradication program for their elite clones and varieties. 

  More recently, I have produced tissue culture plants from heritage Cabernet Sauvignon clones that were acclimated and planted in California vineyards.   This spring (Argentina’s fall) I spent over a month working at a biotechnology company in Mar del Plata in Buenos Aires province.  The laboratory is interested primarily in the micropropagation of different plant species such as garlic, kiwi, fruit, and ornamentals crops.  Recently the lab started working with woody plants such as grapevines and invited me to spend time working and training their staff on grapevine tissue culture and diagnostic techniques.

Plant Tissue Culture

  Plant tissue culture technology (growing plants in vitro) can be used for the quick propagation of grapevines but also is a technique that is used for the elimination of plant pathogens (disease causing agents). The propagation material may start in a greenhouse using either dormant grapevine cuttings or in the lab using nodal sections (portions of a shoot with at least a bud) from an actively growing plant. 

  In the laboratory, a process called surface sterilization is used to remove external bacterial or fungal species that can affect plant growth in culture. The cleaning process involves treating the nodal portions of the vine in a detergent and bleach solution.

  After this process, the nodal sections are placed in a special media that contains nutrients and hormones that sustains plant growth.  These plants are grown in sterile (autoclaved or baked) vessels at ideal light and temperature conditions. This process is known as plant tissue culture initiation.  All the work is done under aseptic conditions in a laminar flow hood that keeps the environment clean and free of airborne microorganisms. If the purpose of initiating plants in tissue culture is the elimination of plant pathogens, the meristematic tissue from each of the plants can be isolated.

Plant Meristem Isolation

  The plant meristem is a portion of the plant with cells that has not differentiated into specialized tissues (e.g., leaves, stems, roots) and are capable of producing a new plant (the tissue is totipotent). The meristematic tissue is also responsible for keeping the plant growing. The advantage of using the apical (the uppermost meristem dome) is that the vascular tissue has not been differentiated and it is expected that viruses (or other pathogens) are not yet present in an infected plant.  By isolating the smallest possible meristematic tissue (generally the meristem dome plus a couple of leaf primordia), and growing it in tissue culture, it is expected that the new plant that is regenerated will be free of pathogens.  The meristem tissue culture technique has been used for decades to produce healthy grapevine plants as well as plants from many other species. The smaller the meristem (0.1- 0.3 mm), the higher is the chance of viral elimination.  However, these small meristems are more difficult to regenerate.  The trick is to isolate many meristems of various sizes (0.1 – 0.5 mm) and test each regenerated plant to determine if the pathogens that were present in the original plant were eliminated.  Because of the small size of the meristems, the work must be done using fine dissecting tools with the aid of a dissecting microscope under aseptic conditions.  Research in my laboratory has shown that tissue culture plants have a higher virus concentration than plants grown in greenhouse or field.  Therefore, the testing of plants to determine their virus status, can start very early in the process, collecting small amounts of tissue during the first transfer to fresh media.

Plant Growth and Propagation

  Once a clone is obtained (always best to produce more than one) that has tested free of the pathogens of interest, the plant propagation starts.  Once the regenerated plants are grown, these must be transferred to fresh media regularly (every 3-4 weeks) to replenish nutrients.  With each transfer it is possible to produce 5-6 new micro-propagated plants.  At some point the plants will be transferred to the greenhouse to be acclimated.  Because there would be a shock for the plants to be moved from the pampered conditions in test tubes, initially the plants must be grown under misting conditions.  In the growth chamber or greenhouse, the humidity must be kept very high to allow the plants to acclimate as they were “spoiled” growing in culture media.  Up to this point, the plants were grown in a clean environment to ensure that pathogens or environmental contaminants were not present. The plants will continue to grow in the greenhouse up to a certain point and brought to the nursery to further propagate and/or start the grafting process.  Because the potential of re-infection, it is important that plants are always protected.  This is accomplished by potting the plants in clean soil and growing in a greenhouse or screenhouse with a mesh that offers insect protection.

Virus Detection and Evaluation of Candidate Selections

  Many vineyards and wineries are interested in propagating their own heritage selections or clones.  In some instances, these clones were introduced hundreds of years ago by families who immigrated from Europe.  At that time, quarantine and plant introduction programs were not as reliable as they are presently.  Consequently, many of the imported grapevine plant material carried important and deleterious pathogens.  In addition, over the years of being planted in the field, even healthy vines may become infected with numerous pathogens due to the spread of pathogens from vineyard to vineyard.

plant in a test tube

  Every project starts with the testing of the plant material the grower wishes to treat.  Based on the results, the laboratory can opt to apply meristem tissue culture or other disease elimination techniques.  Thermotherapy (heat treatment) and cryotherapy (cold treatment) are other methods that have been described and can be used in combination with meristem tissue culture and micropropagation.  But by far, the meristem tissue culture is the most applied method when it comes to disease elimination for grapevines.  This is because the meristem tissue culture is a technique widely accepted by growers.  Although, thermotherapy is a very old and successful method, some growers do not accept its use as they are suspicious that deleterious mutations can occur in the plant material.  This concept has not been scientifically proven though.

  Although generally, the meristem tissue culture technique is applied for viral elimination, a bonus result is the eradication of pathogenic bacteria and fungi.  Because disease diagnostics have been covered in other articles I wrote, I only summarized here.  Basically, the same methods that are used to detect pathogens in the field are used for the detection of viruses (or other pathogens) in tissue culture.  The material being tested however, is always actively growing tissue culture plants.  It is important to test the plants as soon as there is enough plant material and is generally done during the first transfer to fresh culture media (the best conservative sample are leaves with attached petioles).  Because this type of tissue is sensitive to wilting (spoiling) it is important to coordinate testing with the laboratory to assure that the samples arrive in good conditions. The early testing will allow the laboratory to discard the clones that test positive for a pathogen of interest and only propagate those that are not infected.

Conclusions

  The use of tissue culture propagation and meristem culture for disease eradication offers an advantage: the nursery will be starting with a clean product (not only virus tested but likely free of bacterial and fungal pathogens), grown under aseptic conditions.  To preserve, this health status, it is important that plants are moved into a hermetic greenhouse (or screenhouse with small mesh) with mitigation practices to avoid the entrance of insect vectors and /or pathogens.  Finally, the plants must be moved to a screened area in the field (preferably isolated from other grapevine growing vineyards).

  There might be concerns from the industry that tissue culture plants could have juvenile traits (take too long or never produce fruit).  These are valid concerns and the issue varies from variety to variety or even among different clones of the same variety.  There are however growing techniques that can be applied at the nursery to avoid juvenility traits from happening.

  The slogan from the National Clean Plant Network is to “Start clean, stay clean”.  It is important to have nursery programs that produce the cleanest (disease tested) material.  However, if the plants are grown carelessly, likely these plants will become reinfected.  Therefore, my hope is that this article will provide guidelines to allow the planting material to remain clean after the effort and expense of subjecting the material to disease elimination treatments.

GLACIAL TILL VINEYARD & WINERY

Crafting World-Class Nebraska Wines and Ciders

3 woman chilling under sunset

By: Gerald Dlubala

Nebraska entrepreneur and Glacial Till Vineyard and Winery owner Mike Murman spent much of his free time in the 1980s making beer and wine as a hobby. However, when the demands of family life and work travel increased, he put those hobbies on the back burner: Priorities, you know.

  Years later, Murman noticed the increasing number of vineyards and wineries popping up in his home state of Nebraska, renewing his previously tabled interest in winemaking. That spark was enough of a catalyst that Murman joined the Nebraska Winery and Grape Growers Association, attending numerous seminars and workshops over the next two years.

  In 2003, Murman acquired six acres of land located southeast of Lincoln, Nebraska, in Otoe County and near the township of Palmyra, for personal and family use. Primarily purchased as a place to enjoy outdoor sporting and recreation activities, the spacious acreage was close to his family residence and presented the potential for Murman to rekindle his love affair with grape growing and winemaking. The terroir consisted of glacial till, a fertile, rocky soil left behind thousands of years ago after the glaciers that once covered North America receded. Grapevines tend to like this soil mix, so in the spring of 2003, Murman planted the first vines. He approached grape growing in an organized, systematic way, attending additional classes while studying vineyard orientation, preferred soil mixes and all things necessary for grape growing. A local professor from the University of Nebraska helped with soil testing, confirming that the soil was favorable for growing grapes. All property facets met the desired vineyard success criteria except for the slope orientation, his being northward rather than the preferred southward.

  A record harvest in 2006 prompted the Murman’s to share the great wine with others, and Glacial Till Winery was born. In 2008, Glacial Till Vineyard became a bonded winery, which opened to the public in the summer of 2009.

Ability to Adapt Along the Way is Critical

  “We were set on proving to the world that we could make and sell world-class wine in Nebraska,” said Murman. “But we quickly found that in addition to being a very competitive market, it was difficult to change consumers’ mindsets and convince them that world-class wines can come from the Midwest region, specifically the state of Nebraska. We knew then that we wouldn’t make it by solely selling wine, so we started to host events at our production vineyard.”

  “We started an event called Fermented Fridays, regularly hosting live music and food trucks on our property while featuring a local craft brewery,” said Murman. “These became very popular and successful and, for the most part, brought in more money than initially trying to get our wines on the shelves. In fact, the events became popular enough that visitors started requesting the use of our space for weddings and events. Unfortunately, we weren’t set up for that type of event, so we decided to build a venue with proper facilities to host weddings, get-togethers or any other events. It turned into another business element for us, and we continue to expand business elements when we feel it’s beneficial.”

  Murman told The Grapevine Magazine that farm wineries in Nebraska can operate up to five locations, so expansion is always a possibility. In 2010, he took a storefront in downtown Ashland, Nebraska, and transformed it into the Glacial Till Cider House and Tasting Room, offering food service and event space. With subsequent expansion into adjacent available buildings, the space is now 13,000 square feet. Murman believes that any future expansion must include Omaha as a logical location, with the Tri-City area, including Hastings, Grand Island and Kearney, also in consideration.

Early Adversity Leads to a Shift in Direction

  “In 2014, our area had a severe frost and freeze event causing us to lose pretty much all of our grape product,” said Murman. “In Nebraska, by law, our wines have to use at least 75 percent Nebraska-based product, so gaining access to grapes grown in-state for wine production was next to impossible. My youngest son, Craig, came up with the idea of producing a hard apple cider using pressed apple juice. After some thought and knowing that hard ciders were the fastest-growing liquor segment at the time, we started producing our hard cider using pressed apple juice from Kimmel Orchard and Vineyard in Nebraska City. Hard cider is just apple wine that’s carbonated, so we believed it would be a good fit for us and our business. We produced our first batch, and the distributor that sampled it said he would immediately buy all we had. Well, that was all we had, but right then and there, we told him we’d consider making more if there was interest.” 

  Glacial Till’s hard ciders proved very successful, with Murman recognized as Nebraska’s and possibly the Midwest Region’s most prominent hard cider producer. Murman said that when comparing the production and sales between his wine and cider segments, the cider business is actually outpacing the wine segment. In addition, Glacial Till’s hard cider won the Grand National Championship in the U.S. Open, the youngest cidery ever to accomplish that honor. Murman’s knowledge and winemaking history were credited with helping him win that prestigious award.

It’s Okay to Deviate from Original Plans

  With his entrepreneurial background, it was maybe more natural for Murman to adapt to changes in his original plans than it may be for others. Still, he tells The Grapevine Magazine that the ability to adapt and adjust goes a long way in being successful.

  “It really is important not to get stuck in your original plan,” said Murman. “Embracing the entrepreneurial spirit, remaining adaptable and remaining open enough to see, realize and embrace the fact that there may be a different path to success than you originally planned is critical. Here in Nebraska, we’re somewhat restricted from growing as fast as we might like because of the 75 percent rule. Our growth can be restricted based on the accessibility of the product. So it’s perfectly okay to take a different-than-expected path to success.”

  “For example, we never intended to offer a food service, but we also knew we wanted to offer charcuterie or something comparable. COVID hit right after our new building was constructed, and it was then that we decided to open a kitchen and hire a chef because, according to the rules during COVID, places like ours could only stay open if we served food. As a result of that decision, offering food service has now become a priority for us and an important part of our business model. A third of the revenue out of our Ashland tasting room location is derived solely from our food service. It’s just another example of how being open to change and new direction can work to advance your business.”

Advice for Those Getting Started

  “For any grape growers or someone looking to start a vineyard, it’s important to know what varieties do well in your terroir, as well as what varieties are in demand should you look to sell them to wineries,” said Murman. “If you’re just growing grapes for your own consumption, then by all means, grow what you want, but for business purposes, you have to know the types of grapes that are in demand and easier to sell. We researched what varieties would grow best in our area, initially planting eight to 10 varieties, some we knew to be borderline varieties. For those just starting, I think it would be beneficial to concentrate on getting more production from a smaller number of varietals already proven successful in your environment.”

  Currently, Murman grows several varieties on the estate property. Red grape varieties include Frontenac, Chambourcin, St. Vincent, Marquette and a newer offering, Petite Pearl. White grape varieties include Edelweiss, their most popular white, and La Crosse, Seyval Blanc, Vignole and Traminette.

  “In addition to quality grapevine choices, the vine placement matters,” said Murman. “Grapes don’t like wet feet, so it’s important not to plant in low-lying areas because they can be colder, frost-prone and more likely to retain water. Our glacial till terroir provides excellent well-drained soil suitable for grapevines. Grapes like to put down roots with the potential of reaching 20- to 25-foot depths. Since planting in 2003, we’ve never had to irrigate, and our vines do well. We periodically put down nutrients and then do routine maintenance, like mowing, pruning and all the normal expected chores to keep proper airflow throughout the vineyard. What we do have to deal with here in the Midwest is herbicide drift. It’s a concern because most surrounding farms contain row crops like corn and beans, and any herbicides applied have the potential to travel three to five miles under the right conditions. And then we’ve been through battles over the last couple of years with Asian beetles, turkeys, raccoons, birds and other wildlife problems. Some things we can control, and some we can’t. Our weather and climate are changing in that we don’t seem to get the long stretches of extreme winter weather anymore, but rather we have events that are shorter and at times more severe or impactful.”

The Future Is in the Capable Hands of Family

  Murman says that he now considers himself semi-retired, serving in more of a mentor role for the vineyard and assisting with strategy and long-term planning. At the same time, his three sons handle the day-to-day vineyard and winery needs. All contribute in their own way to continue Glacial Till’s quality, consistent production of great-tasting wine and cider year in and year out. Mike’s oldest son, John, studied under his father and took additional courses to assume the role of winemaker while also running the production and vineyard operations. Tim serves as the general manager, responsible for the back office, including accounting, distribution and distributor relationships, while also looking over the event and tasting room staff. Craig, the youngest, is responsible for all of the creative and technical aspects of the winery, including TTB compliance and reporting, wine labeling, web and social presence and marketing. Glacial Till Vineyard and Craft Cider House employs approximately 15 full-time and 65 seasonal or hourly employees.

Addressing Smoke-Impacted Wines

By: Becky Garrison 

In a press release dated May 5, 2023, Willamette Valley Vineyards, Brigadoon Wine Co., Samuel Robert Winery, Retraite, LLC (F/K/A Lingua Franca – LS Vineyards Holdings, LLC) and Elk Cove Vineyards Inc. announced they hired a well-known legal team to investigate filing suit against Pacific Power, a division of PacifiCorp, in the Oregon state circuit courts. The wineries issued this joint statement:

  “These fires devastated our industry, and we believe it’s time we investigate seeking compensation. We are encouraged by the recent news reports that the other fire victims in the state are finally able to settle their claims against Pacific Power (PacifiCorp). We have hired the lawyers who led the $13.5 billion recovery for the 70,000 victims in the PG&E bankruptcy in California and who recently settled their lead fire victims’ claims against PacifiCorp in the Archie Creek Fire litigation in Douglas County, Oregon.”

  As evidenced by the wildfires impacting the West Coast in subsequent years, coupled with the current wildfires raging in Canada impacting the East Coast and the Midwest, the issue of smoke damage to wine grapes remains an ongoing concern. During the Oregon Wine Symposium held on February 14-15, 2023, moderator Greg Urmini, operations lead for White Rose Estate in Dayton, Oregon, led a panel of winemakers and researchers to discuss smoke-impacted wine. Urmini pointed to the significance of this topic, noting, “It’s important to understand what winemakers are doing to help save their wine because we have to continue to make wines, and we want to be able to provide a good product.”

CASE STUDY: Barrel 42 & Quady North Winery (Jacksonville, Oregon)

  As a founding member of the West Coast Smoke Exposure Taskforce, Nichole Schulte, winemaker and partner of Barrel 42 and Quady North Winery, has experienced trial by fire literally while dealing with multiple smoke indigents over the past decade in Oregon. Overall, she stresses the need to collaborate with local winegrowers and winemakers ahead of time so there’s a strategy already in place regarding what can be done in the winery and the vineyard.

  In assessing the risk of a particular wildfire, Schulte looks at three factors. First, she observes the proximity of the smoke event to the vineyard, adding that the AQI (Air Quality Index) measurements do not provide a direct relationship between air quality and the volatile smoke-related compounds (“phenols”) floating around in the air. Also, she examines the freshness of the smoke, adding that these phenols can degrade or drop out over time.

  The grapes soak up these phenols, which bind to sugar though how much sugar is absorbed by the grapes depends on the varietal and the growing stage. Some grapes ranked from highest to lowest risk for negative effects from smoke damage include pinot noir, grenache, sangiovese, cabernet franc, primitivo, zinfandel, cabernet sauvignon, merlot and syrah.

  While the most vulnerable times for grapes coincide with wildfire season, there’s no carryover impact in the vineyards from previous wildfire events. Preliminary indications of using barrier sprays in the vineyard show to be very promising. In addition, hand harvest reduces maceration time from harvest to the fermenter. Sort out as much MOG as you can, which means not doing a full cluster ferment. Whole berry ferments tend to produce fruity aromas and esters that can, to some degree, mask the smoke characteristics in the wine. Along those lines, there’s some indication that washing ash off the fruit clusters can help reduce the presence of smoke.

  As you handle smoke-impacted grapes from fermentation to élevage, be mindful that volatile phenols will express early in fermentation. When doing trials where they separated press factions, the data showed that the compounds were still present but that the sensory profiles differed from a light to a heavy press. 

  When conducting experiments to see how certain barrels interact with smoke-impacted wines, they found that the higher the toast of the barrel, the more it interacts positively with the smoke impact of the wine. Also, untoasted oak chips can mask and bind up some phenols, while toasted oak can provide sweet, more complex tannins.

  In Schulte’s estimation, white wine is easier to deal with since you can get the juice off the skin as soon as possible. Hand-harvest the grapes and minimize skin contact and maceration time. Press gently, keeping heavy-pressed juice segregated for possible treatment later or just to keep it out of the main juice. Be sure to discard the solids, though this can be tricky as yeast will need some solids. So, consider using solids and lees from non-impacted lots. But if you can clarify before fermentation, then there’s almost no smoke at the end. For fining, they had success with bentonite, activated carbon and PVPP, as well as Clanil SMK (Enartis), which is a blend of activated carbon, chitosan and pea protein.

  Finally, wine made from smoke-impacted grapes should be bottled and consumed early. Aging these wines will not improve their quality.  

CASE STUDY: Battle Creek Cellars (Portland, Oregon)

  Winemaker Sarah Cabot focused specifically on fruit from Willamette Valley’s 2020 harvest. When presented with smoke-impacted grapes, her first question was whether or not to ferment on skins or go directly to the press. With white varietals, she went directly to the press. Conducting a berry analysis proved to be a good way to determine how much smoke is too much with regard to fermenting on skins.  

  When making white and rosé wines from smoke-impacting grapes, Cabot found that floating was an effective way to clarify the juice, though it only works if there’s a pretty significant volume. Also, the first eight to 10 gallons were discarded. She succeeded with gentle pressing and pre-fermentation, fining with carbon and bentonite with daily stirring for three days, then settling for three days. In her anecdotal sensory analysis, the pre-fining juice smelled like a campfire, though the post-fining juice smelled good. According to Cabot, spending the extra money on pre- and post-treatment before deciding to bottle is worth it in the long run.

  Next, she proceeded with fermentation as usual, adding that this worked best when they chose to go through the process quickly. She took some extra measures during fermentation, finding that there was some evidence that chitosan mitigates the effect of smoke. Also, mannoproteins/polysaccharides, untoasted oak tannins and a vigorous yeast strain with a short lag phase produced high esters. Then she suggested bottling at or above three grams per liter of residual sugar, adding that the higher the sugar, the more pleasing the experience.

  When addressing protocols for red wines, Cabot observed that the best sensory analysis results came when using a high temperature with a heavy mace ratio. The more heavily extracted, fruit-forward wines before smoke mitigation treatments yielded the most balanced and enjoyable wines after treatment.

  Going into élevage, she kept the free run and press fractions separate, adding that the press fraction required a much heavier treatment. If there are a lot of bound compounds, a winemaker can attempt enzymatic hydrolysis in the tank. By holding the wine at a temperature of approximately 64 degrees Fahrenheit for four to six weeks with regular agitation, the results were anywhere from a 15 to 75 percent reduction in glycosylated markers and a corresponding increase in free volatile phenols on all samples analyzed. While this method proved to be effective for her, she admitted it was a pretty extreme thing to do.

  Based on her experience with the 2020 vintage, Cabot concluded that it is possible to make an enjoyable, early-release wine from smoke-affected fruit at a slightly higher final production cost that people will enjoy. With red wines, especially pinot, a heavy extraction approach yielded the best post-treatment result. Also, the commonly publicized “Best Estimate Sensory Thresholds” for VPs seem accurate according to most tasters. In the event of another smoke event, Cabot would stick with the early release and early consumption wines. Also, she would repeat her decision to produce only the sub-$25 SRP pinot noirs due to insufficient data on the long-term bottle aging effects of smoke markers.

Should I Open Up a Claim?

close-up of a plant crop

By: Trevor Troyer, Agricultural Risk Management

When to open up a claim on your grape crop insurance is important.  A lot of growers say that don’t know if they have a payable loss early in the season.  With grape crop insurance you are covering an average of your production per grape variety. Depending on what coverage level you have chosen this could mean you have a large deductible or small one.  I agree it is hard to tell how much early season damage will affect tons harvested.

  Mid May this year there was a bad freeze/frost event in the Finger Lakes region of New York.  While late spring frosts are not uncommon, this one was really bad.  There was widespread damage to grape vines across the Finger Lakes.   The extent of the damage is not fully known at this time.  But there will be a reduction in the tons harvested this year for sure.

  In a situation like the above a claim should be opened immediately.  More than likely, due to the severity of the frost, an adjuster will come out and inspect the vineyard.  I always tell growers that they should take pictures of the frost damage that morning.  It is always good to document damage as close to the time it occurred as possible.

  It may be that some varieties of grapes show more damage than others.  This is to be expected as some are more resistant to cold.  And from what I have seen over the years with frost and freezes is that it doesn’t affect a vineyard or field evenly.  You might have more damage on one side of the vineyard or more damage on the lowest part of the blocks etc.  Damage varies but just because one variety or one area looks better than others doesn’t mean that you should not open a claim on that variety or block.

  I know that secondary and tertiary buds will emerge in the next few days or weeks after a freeze.  You should open up a claim now regardless.  The damage may be less than you think and you don’t end up having a payable claim.  But it is still best to get one opened up right away.  Don’t wait to see how many tons you harvest before opening a claim! 

  Here is an excerpt from the “How to File a Crop Insurance Claim” Fact Sheet from the USDA:

  Most policies state that you (the insured) should notify your agent within 72 hours of discovery of crop damage.  As a practical matter, you should always contact your agent immediately when you discover crop damage.

  That same night in May, that saw the frost/freeze in the Finger Lakes region, also saw damage to vineyards along the coast of Lake Erie.  I received calls and emails from growers stating that they had had frost as well.  Obviously, the damage was not as bad as the Finger Lakes, but frost on new buds is not something any vineyard owner wants to see.  I opened claims for all of them even though the extent of the damage was not known.

  I cannot stress enough the importance of opening up a claim early. 

  A lot of claims with grapes are relatively routine.  Once the claim is opened an adjuster will come out and document the damage.  You will continue to grow your crop and try to mitigate any damage received. Once you harvest grapes you will meet with the adjuster and give him your production records that show your tonnage per variety.  He will then adjust the claim based your guarantee (average tons per acre per variety and the price for that variety in the county.)

  In some circumstances you will need to get direction from the adjuster before doing anything.

What are your responsibilities after damage if the grapes have not matured properly and will not?  What if they have been rendered unusable (smoke-taint has been a major cause of this in California)? 

  Here is a section from the Grape Crop Provisions that goes over this:

11. Duties in the Event of Damage or Loss.

In addition to the requirements of section 14 of the Basic Provisions, the following will apply:

(a) You must notify us within 3 days of the date harvest should have started if the crop will not be harvested.

(b) If the crop has been damaged during the growing season and you previously gave notice in accordance with section 14 of the Basic Provisions, you must also provide notice at least 15 days prior to the beginning of harvest if you intend to claim an indemnity as a result of the damage previously reported. You must not destroy the damaged crop that is marketed in normal commercial channels, until after we have given you written consent to do so. If you fail to meet the requirements of this section, all such production will be considered undamaged and included as production to count.

  It is important to stay in contact with your adjuster during a claim.

  A lot of things can happen to your vines that could cause them not to produce a full crop.  The insurance period is long and it is important to report everything that may reduce your crop.

  When you sign up for crop insurance, coverage for grapes starts on February 1 in Arizona and California.  It begins on November 21 in all other states.  The end of insurance unless it is otherwise specified by the USDA RMA, is October 10th in Mississippi and Texas, November 10 in Arizona, California, Idaho, Oregon and Washington.  In all other states the end of insurance is November 20th.  Crop insurance is continuously in force, once signed up for, unless cancelled or terminated.  Your coverage for following years, will be the day after the end of the insurance period for the prior year.

Here are the Causes of Loss per the Grape crop provisions:

(1)   Adverse weather conditions;

(2)   Fire, unless weeds and other forms of undergrowth have not been controlled or pruning

       debris has not been removed from the vineyard;

(3)   Insects, except as excluded in 10(b)(1), but not damage due to insufficient or improper

       application of pest control measures;

(4)   Plant disease, but not damage due to insufficient or improper application of disease control

       measures;

(5)   Wildlife;

(6)   Earthquake;

(7)   Volcanic eruption; or

(8)   Failure of irrigation water supply, if caused by an insured peril that occurs during the

       insurance period.

  Adverse weather conditions could be anything that could cause damage to your grapes. For

example; drought, frost, freeze, excess moisture etc. Wildlife could be bird damage, deer etc.

Fire would also include smoke taint as that is a result of a fire.

  Crop insurance does not cover, the inability to sell your grapes because of a buyer’s refusal or contract breakage. It also doesn’t cover losses from boycotts or pandemics. Phylloxera is not covered, regardless of the cause. Overspray or chemical damage from a neighboring farm is not covered either.

  So, get those claims opened up early and stay in contact with your agent and adjuster.

Permit-Required Confined Spaces

Occupation Safety and Health Act

By: Steven R. Sawyer, ARM, MS, CSP

As many employers have learned over the last few years, employees are a valuable resource.  The ability to find and keep employees has become a challenge for many employers in a variety of industries, including food and beverage agriculture.  Therefore, keeping employees safe is a top priority.

  Employers in the food and beverage agriculture industry, like vineyards and wineries, may have multiple confined spaces in which employees encounter in their daily job tasks.  These include vats, tanks, storage bins, tunnels, duct work, pits, drain systems, and liquid tanks and containers.  Many industry employees are required to enter these spaces as part of their jobs.

  Occupational Safety and Health Administration (OSHA), in their Permit-Required Confined Spaces standard 29 CFR 1910.146, describes a confined space as a space that is large enough for an employee to bodily enter and perform assigned work tasks, has a limited or restricted means of entry or exit, and is not designed for continuous employee occupancy.  Additionally, OSHA defines a Permit-Required Confined Space as a confined space with one or more of the following characteristics:  the confined space contains or has the potential to contain a hazardous atmosphere; the confined space contains a material that has the potential for engulfing the entrant; the confined space has an internal configuration with inwardly converging walls or a floor that slopes downward and tapers to a smaller cross section which could trap or asphyxiate an entrant; and contains any other recognized serious safety or health hazard. (OSHA.gov)

  The first step in protecting employees from the hazards of confined spaces is to evaluate the workplace to determine if the workplace contains permit-required confined spaces.  An initial survey or workplace evaluation should be conducted to locate and identify all confined spaces.  This initial workplace evaluation should be conducted by a qualified person who is familiar with the hazards and types of confined spaces.  Although this is the initial step, workplace evaluation must be ongoing for confined spaces which may change over time with the addition of new processes, equipment, or facilities.

  Once a confined space is identified in the workplace, the confined space should be treated as a hazardous area until a qualified person can determine the specific hazards.  Additionally, the qualified person will determine if the confined space is a permit-required confined space or a non-permit confined space.  Hazards an evaluator will look for include atmospheric hazards such as oxygen deficient or toxic atmosphere, biological hazards, mechanical hazards, physical hazards, and chemical hazards.

  If the qualified person has found permit-required confined spaces at the workplace, the employer must notify the employees.  Employees must know their workplace contains permit-required confined spaces, where the spaces are located and the hazards associated with those spaces.  Then, the employer must post signage to inform the employees of the permit spaces.  This signage can read “Danger – Permit-Required Confined Space, Do Not Enter” or a similar statement.  The signs should be posted on the entrance or in close proximity to the entrance of the permit space.

  At this point, an employer has a decision to make about their Permit-Required Confined Spaces:  either allow employees to enter or do not allow employees to enter.  If the employer makes a decision to not allow employees to enter permit spaces, then the employer should take effective measures to secure the spaces.  Some examples of securing permit spaces to prevent entry are padlocks, bolts, chains, and wire cables.

  If entry is necessary for employees to service or clean permit-required confined spaces, the employer must develop and implement a written permit-required confined space program and make the program available for employee inspection.  This written program should include written entry procedures for the permit-required confined spaces along with the hazards present, and how to eliminate or control the hazards. 

  The written permit-required confined space program should include an entry permit.  The entry permit is a document to be used for all permit-required confined space entries.  The entry permit should include the date of entry and authorized duration of the entry, the location of the entry, the names of all entrants, and the work that is being conducted in the confined space.  Additionally, the permit must include the names of attendants, the name of the entry supervisor, the hazards present in the space to be entered, how the hazards will be eliminated or controlled before entry, acceptable entry conditions, results of initial and periodic tests performed along with the names of the testers and when tests were performed, rescue and emergency services to contact in the event of an emergency, communication procedures between the entrant and the attendant, equipment necessary including personal protective equipment, testing equipment, communication equipment, alarm systems, and rescue equipment, other information deemed necessary for safe entry, and any additional permits such as hot work permits.  Lastly, the permit should have a signature line for the entry supervisor to authorize the entry, including the date and time of the entry.  The entry supervisor should communicate the contents of the entry permit to the authorized entry personnel and may wish to post the entry permit in a designated location.

  OSHA requires that employers provide training for all employees who must work in permit-required confined spaces.  The training should occur before the initial work assignment, when job duties change, employee performance deficiencies occur, or when the permit-required confined space program changes or operations change.  Although it is not required to train all employees to the extent of the authorized entrants training, it is a best practice to inform all employees of the confined spaces present in the workplace and the hazards that accompany the confined spaces.  

  If entry is required in a permit-required confined space, the employer must provide an authorized entrant (the person who enters the space and conducts maintenance or cleaning operations), an attendant (a person who remains outside of the confined space), and an entry supervisor (the person who oversees the entry operations and ensures the entrants follow the permit and are safe).  These personnel have specific duties that must occur to ensure safe entry into permit spaces.  Their duties must be followed in order to comply with the OSHA Permit-Required Confined Spaces standard.

  When the entry into the permit space is complete, the entry supervisor terminates the confined space entry.  The entry supervisor can also cancel the entry of the confined space if the conditions within the space are no longer safe for the entrant.  As a best practice, when the entry is complete, a debrief should be conducted with the entry personnel to determine if any changes are needed for future entry procedures.  Employers are required to keep canceled entry permits for one year.  Any deviations or problems with the entry should be noted on the canceled permits.

  Even with a permit-required confined space program in place, emergencies can happen.  It is important that local emergency responders are aware of the specific hazards associated with confined spaces in the workplace.  Invite local emergency agencies to the workplace and evaluate their knowledge of confined space rescue, their rescue equipment, and their capabilities. 

  Having a permit-required confined space program in place will help vineyards and wineries avoid catastrophic incidents and costly OSHA citations.  To learn more about Permit-Required Confined Spaces, go to osha.gov or ansi.org.

New Grapevine Insurance Program

Grape crop insurance has been available for many years now.  You can protect an average of your historical tonnage per variety.   But there has not been an insurance program for grape vines.   There are subsidized insurance programs for apple trees, orange trees, avocado trees, mango trees etc. through the USDA Risk Management Agency.  But there has not been anything for vineyards, until now.

  AgriLogic Consulting, LLC is consulting company that develops crop insurance products for the USDA.  They do feasibility studies and evaluations of existing and potential programs.  AgriLogic Consulting, LLC has been working on a Grapevine insurance program.

  Here is what was just released on the AgriLogic website, agrilogicconsulting.com

  The Grapevine Insurance Program has been approved by the Federal Crop Insurance Corporation for implementation in the following states: California, Idaho, Michigan, New York, Ohio, Oregon, Pennsylvania, Texas, and Washington. Insurance industry representatives in key production regions requested a product to protect producers against perils that can destroy vines. The list of perils to be included are freeze, hail, flood, fire, and failure of the irrigation water supply (if caused by an unavoidable naturally occurring event during the insurance period). Claims will be limited to loss due to complete destruction or death of the vine. Losses for partial damage are not included under the program. While both programs are federally subsidized and administered by the USDA Risk Management Agency (RMA), the vine replacement program is different and separate from the existing Grape and Table Grape Crop Insurance Programs, which cover losses related to the production of the fruit itself. Producers will be able to purchase the vine insurance program through existing crop insurance agents once the program becomes available.

  I don’t have to tell you that this is a big deal.  I know vineyards that have wanted this for years and nothing has been available.  I have seen vineyards devasted by fire in California and Oregon in recent years. I have seen damage from early freezes in Pennsylvania and New York.  This program will give growers much needed protection for their vines.

  The policy documents are set to be released to the approved insurance providers by no later than August 31, 2023.  The sign-up deadline for the new Grapevine Insurance program will be November 1st, 2023.  Availability maps should be released at the end of August as well.

  At this point we do not have any information than the above.  I look forward to helping vineyards get coverage for their vines.

Could the Wine Industry Benefit from Virtual Assistants?

Digital innovations within the workplace are nothing new these days. With more and more people working from home, employees are becoming accustomed to relying on technology to help with work-related tasks that used to be completed in person.

  Today, virtual assistants (VAs) are changing the way companies interact with and engage customers, get their name out into the market, and improve overall profits. VAs are part of the digital revolution that has reinvented the landscape of modern work, and business leaders across a wide array of industries are leveraging the skills these professionals offer to help scale their businesses, manage tasks, and free up their time.

  When one thinks about viniculture and the wine industry, it may bring to mind images of vast fields of grapevines, wineries with knowledgeable sommeliers giving in-person recommendations, and an age-old, often family-based company structure. One’s mind typically will not jump to a tech-heavy culture.

  However, according to a recent article in Forbes, many wine companies have not only adapted to changes in technology, but debuted some wine industry-specific innovations. For instance, some companies have outfitted their wine labels with QR codes that give consumers greater insight into the wine’s origins. The company Sparflex has developed a wine foil that allows the consumer to access animations straight from the label, and WineCab is a robotic, AI-powered sommelier; some wineries are even using drones and satellites to collect data on their vineyards.

  Although the viniculture industry may not seem one “ripe for the picking” for help from virtual assistants, the wine industry has a history of adaptation to new technologies and innovations. This could make them the perfect industry to adopt the use of VAs. 

What Value can VAs Bring to Winemakers and Viniculture?

  Virtual assistants are remote workers who can help companies with a number of tasks, and their role has taken on new meaning as remote work has grown in popularity. Once used for mainly administrative tasks, VAs are now heading up social media campaigns, handling the entire accounting or customer service department of companies, and — in some cases — even stepping into C-suite leadership roles.

  Throughout the past several years, the wine industry has faced the same challenges that many other industries have run across, including customer service concerns, supply chain issues, and a focus on employee retention in the wake of the Great Resignation. Virtual assistants can help winemakers navigate these challenges as well as many others.

  One of the biggest benefits a VA can bring to the wine industry is their ability to take on tasks that may not be in the wheelhouse of a business owner, CEO, or other leaders. VAs can also be instrumental in helping leaders better focus on the tasks where they excel. Attempting to scale a business on one’s own is remarkably difficult, especially in an industry as inherently collaborative as viniculture, where different teams are responsible for harvesting the grapes, making, selling, and marketing the final product.

  Studies have shown that taking on a VA can improve productivity overall in one’s business, including the wine industry, where overall productivity could make or break a winery. VAs can also help lower overall operating costs by up to 78%, which could provide crucial savings for a startup in the wine industry.

  Virtual assistants can give an owner more time to focus on what they really want to do: building their businesses. Winemakers may be surprised at how adaptable and multi-faceted VAs are, and what they can do to help a winery, vineyard, or wine store scale.

  Running and managing social media accounts

It can be difficult — if not completely impossible — to run a successful business these days without using social media effectively. Many people may not know how to leverage social media for their wine business, but there are VAs who are highly skilled in areas of social media marketing and engagement that can help one uplevel their business.

  Social media is largely about visuals, and one may wonder how someone who may work halfway around the world can help with the visual marketing of a business that is in, say, Napa Valley. Yet, because so many aspects of the modern workplace have been digitized, it’s extremely easy for a VA to take images or videos from a winery’s events — or even its wine-making process itself — and use those on social media sites to further establish its brand presence.

  VAs can also handle the engagement side of social media, which can be one of the most time-consuming aspects of digital marketing. After all, customers who are interested in your product because they saw some compelling images online will want to engage with your brand by liking, following, and sharing your content on social media.

Facebook

  According to research, 70% of adults use Facebook, many of whom use their connections to brands on social media to make purchase decisions. When a brand actively engages with followers online, it increases the likelihood that the person with whom they are engaged will return to make a purchase.

  In this regard, VAs can also handle the involved job of social media advertising. Running social media ads is highly effective. In fact, that same research shows that 49% of people will be more apt to purchase an item if they see an ad for it on social media. However, running, organizing, and keeping on top of social media ads can be tricky — even for social media-savvy CEOs. Having a person whose top priority is to run and track social media ads can greatly improve a company’s reach and revenue.

Instagram

  Instagram is where social media users go for imagery, and where a winery’s brand presence could easily entice customers with beautiful pictures and engaging video content. Instagram is all about meeting wine enthusiasts where they are, as these consumers are the ones sharing their own pictures of vineyards, bottles, and glasses of their favorite wines.

  Instagram posts that tend to garner the most engagement are those that highlight the human element of the business behind the screen. A great example is Tank Winery, which has harnessed the power of Instagram with personal, informative, and entertaining stories and posts that grab attention. Virtual assistants that are well-versed in the visual-heavy Instagram approach can help uplevel a business’ presence on the platform by consistently posting engaging content.

Tiktok

  As of September 2022, TikTok is the most downloaded social media app in the US for the third year in a row. Many VAs are also TikTok experts and can help a winery or vineyard get its head around what is likely to “go viral” on the popular platform. TikTok can be a great platform for robust marketing strategies and interesting dives into wine-related content, be they virtual tastings, or informative videos about a particular wine or brand.

  Consistency is key with all social media platform posting. Some studies show that businesses should post 1-4 times a day to have a chance of reaching viral status, but most winemakers simply do not have the time to consistently post on platforms for maximum engagement. This is where hiring a VA can help their business achieve the consistency they need to best leverage social media.

Customer Service

  If there is anything that can make or break a business, it’s customer service. No matter how great a winery’s product may be or how skilled its wine experts are, its entire operation can steadily dry up if its customer service is lacking.

  Customer service needs to be top-notch with not only consumers, but suppliers and the stores that carry one’s product. Even when they are positioned halfway around the world, VAs can field phone calls, respond to emails in a timely manner, manage chatbot functionality on your website, and provide assistance with issues that may arise. If a company is looking to expand on a global scale, having a VA in a different time zone could prove to be a massive asset.

  Additionally, as online shopping has become the norm since the pandemic, it is now even more crucial that the wine industry master omnichannel marketing tactics and remain able to pivot alongside changes in consumers’ purchasing habits. Wineries, vineyards, and other businesses in the industry need their customers to be informed and taken care of during every stop in the engagement and purchasing process. VAs can help cover the omnichannel bases, assisting with social media channels, mobile communication, and customer support online.

  By utilizing VAs on the customer support end, customers will feel heard and vendors will feel secure in knowing someone is on top of their needs. Founders and CEOs cannot possibly be everywhere at once, but allowing a VA to help with some of the ongoing customer service tasks allows them to concentrate more on the crucial aspects of their wine business requiring their attention.

  Establishing and building an online presence

A skilled VA can handle a business’s entire online presence, from website design, to updates, to running its online e-commerce store. They can spearhead the time-consuming tasks such as uploading images and information for each product that you sell, writing blog posts that further engage clients and customers, or stepping in at a moment’s notice if one’s website experiences issues and goes down. VAs experienced in event management can even host online events, such as virtual tastings or wine workshops.

  The last few years have been instrumental in building online sales innovation for the wine industry. One study showed that online wine sales skyrocketed during the pandemic and held steadily above pre-pandemic levels, even as in-person tasting rooms reopened.

  Overall, wineries stepped up their online offerings during the pandemic, with 44% of them offering online tastings and other incentives to engage online shoppers; only 22% of wineries neglected their online presence during the pandemic. The online shopping capabilities of a wine business are important for attracting and retaining loyal customers, as well as maintaining their position amid heavy competition.

  Virtual assistants can help with a number of other tasks outside of those mentioned here. Other tasks that are essential to a business, but that leaders may need a VA’s support with, run the gamut from accounting to HR, to SEO and admin. As the wine industry increasingly adapts digital tools and technologies, virtual assistants will take their place as some of the industry’s most invaluable employees.

  As a leader in your wine business, no one is expecting you to be an expert in everything. But by utilizing virtual assistants, you can outsource the expertise necessary to keep your wine business thriving and growing year after year.
