Important Plant Health Issues to Take into Consideration

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

As many of you already know, I am a plant pathologist consultant specializing in the detection and control of grapevine diseases. The diseases work with are those that are graft transmitted but are also can spread in the vineyard.  Once the vines are planted, these diseases cannot be cured using chemical or other means.  It has happened too many times that I am called to determine what is wrong at a vineyard.  The story goes sometimes like this, “we purchased the vineyard in the winter, so we were unable to see any tell-tale signs of disease”, “we consulted with our county officer and s/he said things looked OK”; We really were not thinking about disease, we fell in love with the beautiful setting and the house”; “We did not know that red foliage is an indicator of virus infection”; the scenery in the fall season is an explosion of colors, so beautiful, so romantic”.  I can go on and on with more quotes buttthink that you understand the problem.  I wish these people would have called me before they purchased the vineyard.  Now it is a bit late.

  In this article, I will highlight issues that can become a problem after a vineyard purchase.  It is my hope to educate the reader and encourage them to contact me prior to signing the purchase contract to allow a thorough evaluation of the vineyard health status.

The Best Time to Inspect a Vineyard for Disease Presence

  As mentioned earlier I will only focus on graft transmitted diseases that cannot be cured once established in a vineyard.  Diseased grapevine plants may display different symptoms of infection  at different times of the year or seasons.  Early in the spring  and summer months it is easy to spot diseases caused by declining bacteria (i.e., Pierce’s disease, crown gall), fungi (Eutypa and Bot canker, black foot, etc.), and viruses (fanleaf and other nematode transmitted virus species).  In late summer or fall, viral diseases that cause leaf reddening and a variety of color schemes (leafroll, red blotch, Vitiviruses) can be observed.  To complicate matters, these diseases or their disease-causing agents can be found in all sorts of combinations.  Further, some of these diseases show almost exactly the same symptoms, in all cases a knowledgeable plant pathologist will be required to help identify the issue or recommend testing, especially when no symptoms are present due to seasonality.

  Below I describe some of the most important diseases likely present in vineyards:

Bacterial, Fungal and Viral Pathogens Best Detected in the Spring

Petri Disease, Young Vine Decline, Esca:  The disease in young vines, known as young vine decline, is caused by Cadophora, Phaeoacremonium, and Phaeomoniella species.  In older vines, the same fungal pathogens are associated with Esca disease.  The disease is chronic when vines express a gradual decline of symptoms over time, or acute when the vines decline and die within a few days.  These acute symptoms are known as the apoplectic stage of the disease. It is not uncommon during the apoplectic stage of the disease to see dead vines carrying mummified grape bunches.

Canker Diseases:  Various pathogens can cause canker symptoms, large discolored areas in trunk and canes, in the vineyard. Bot-canker or dead arm disease is caused by different species in the Botryosphaeriaceae family. Eutypa dieback is caused by different species in the Diatrypaceae family.  In my lab we characterized Seimatosporium species as a fungal pathogen that causes decline and cankers in grapevines, but within the same fungal group others have reported Pestalotoipsis and Truncatella to cause disease in grapevines. The canker symptoms observed in the sections of affected cordons or trunks in grapevines may appear to be similar but caused by unrelated fungal species.

Black Foot Disease:  Species of Campylocarpon, Cylindrocladiella, Dactylonectria, and Ilyonectria (previously known as Cylindrocarpon spp.) are the causal agents of this complex disease.   These fungi are soil-born and most active on compact soils with poor drainage.  Symptoms above ground can be indistinguishable from young vine/ Esca disease described above.  Additionally, the decline symptoms can be confused with Pierce’s disease (to be described below).

Grapevine Fanleaf and Other Nepoviruses

  Arabis mosaic (ArMV), Grapevine fanleaf (GFLV), Tobacco (TRSV) and Tomato ringspot (ToRSV) are viruses that cause decline in grapevine.  These are specifically transmitted in the vineyard by different nematodes in the Xiphinema species.  The symptoms caused by these viruses are very similar and include foliar deformation, vein banding, and most importantly uneven maturation and sparce production of berries.  Since this is a soilborne disease, it manifests in patches in the vineyard where the nematode vector is located.  The transmission, of course can happen through infected material, but not commonly as it is an easy virus to detect using various laboratory techniques.

Pathogens Best Detected in the Late Summer and Fall

Pierce’s and Crown Gall Disease:  Pierce’s disease is caused by Xylella fastidiosa, a bacteria transmitted by sharpshooter sucking insects.  The control of the disease is complicated as the bacteria infects many different plant species (i.e., has a broad host range).  The symptoms observed in early spring are vine decline and poor bud break, in the fall it is possible to observe typical “green islands” on the canes as well as the “match stick” symptoms.  Green islands are areas of the canes that do not mature evenly (uneven lignification), while match stick symptoms is a phenomenon in which the petioles remain attached to the canes while the leaf blade has fallen off.  Crown gall is caused by another bacteria: Agrobacterium vitis. The typical symptoms of crown gall disease are galling at the crown of the vine (hence its name), however galls can occur at the graft union or other areas of the vine. I have recently written about crown gall disease in grapevine and will not elaborate on this article. 

Fungal Pathogens and Mixed Infections:   The fungal pathogens and the crown gall bacteria mentioned above can be detected all year round and often occur in mixed infections with viruses and/or bacteria.  Some years ago, Central Valley growers in California reported a syndrome in which their vines collapse and die within a short period of time.  While working at STA (the laboratory I developed that specialized in grapevine diagnostics) we tested vines with similar symptoms, not just from California’s Central Valley but also from California’s Central Coast vineyards.  We detected a combination of fungal pathogens (not always the same usual suspects) and viruses, such as Grapevine leafroll associated -3 (GLRaV-3) and the Vitiviruses Grapevine virus A and F.

Grapevine Leafroll and Red Blotch:  Although the symptoms observed in vines infected with Grapevine leafroll and red blotch viruses are similar, these diseases are caused by different viral species.  The symptoms are observed in the late summer and fall and appear as a display of a palette of different colors.  Some species of leafroll are transmitted non-specifically by mealybugs while red blotch virus was reported to be transmitted by plant hoppers in the Membracidae family, In the next Grapevine Magazine issue I plan to write an article with more details on epidemiology and management of these diseases. Stay tuned!  

Conclusions

  The purchase of a vineyard is a huge investment and because of this It is important to take into consideration its plant health prior to purchase.  Because symptoms of disease vary along the different seasons, I recommend planning to test a representative sample for important diseases during the due diligence period. Be aware that certain viruses/pathogens are detected more readily in different seasons.  This is why it is so important to hire a knowledgeable professional that can walk you through the process. 

  My philosophy is always prevention, so my recommendation to buyers as well as sellers is to be aware of the infection status of planting material, this will avoid the presence of detrimental pathogens in the vineyard in the first place.

A Short and Quick Guide to Wine Importation Regulatory Process

Cyndi

By: Brad Berkman and Louis Terminello

Importing wine into the United State may initially seem like a daunting task. Licensing requirements and related matters appear to be complex with requirements at both the federal and state levels. With proper planning and guidance, the insurmountable becomes a manageable process. This article will act as a short guide to the initial licensing and regulatory concerns encountered by new importers.

Licensure At the Federal Level

  Importation of wine into the stream of commerce of the United States is regulated by the Alcohol and Tobacco Tax and Trade Bureau (TTB). Prior to importation, the potential importer must qualify to hold a TTB Basic Permit as an Importer. TTB examines the qualifications of the owners and officers through a personal questionnaire process that is executed under the penalty of perjury to ensure that the individual applicant is not impaired from holding the permit. Qualifications of applicants can be found in the Code of Federal Regulations. Printed below are the code sections showing the requirement for licensure and the required qualifications for licensure.

§ 1.20 Importers.

  No person, except pursuant to a basic permit issued under the Act, shall:

(a) Engage in the business of importing into the United States distilled spirits, wine, or malt beverages; or

(b) While so engaged, sell, offer or deliver for sale, contract to sell, or ship, in interstate or foreign commerce, directly or indirectly or through an affiliate, distilled spirits, wine, or malt beverages so imported.

§ 1.24 Qualifications of applicants.

  The application of any person shall be granted, and the permit issued by the appropriate TTB officer if the applicant proves to the satisfaction of the appropriate TTB officer that:

(a) Such person (or in case of a corporation, any of its officers, directors, or principal stockholders) has not, within 5 years prior to the date of application, been convicted of a felony under Federal or State law, and has not, within 3 years prior to date of application, been convicted of a misdemeanor under any Federal law relating to liquor, including the taxation thereof; and

(b) Such person, by reason of the person’s business experience, financial standing or trade connections, is likely to commence operations as a distiller, warehouseman and bottler, rectifier, wine producer, wine blender, importer, or wholesaler, as the case may be, within a reasonable period and to maintain such operations in conformity with Federal law; and

(c) The operations proposed to be conducted by such person are not in violation of the law of the State in which they are to be conducted.

  In conjunction with the personal questionnaire process, the applicant entity is disclosed including ownership structure. Among other things, certain signing authorization forms are prepared, and parties are assigned signing authority on TTB documents.

  In addition to the Importers Basic Permit, it is wise for the applicant to apply for a federal wholesaler’s permit. This permit will allow the licensee to ship alcoholic beverages in interstate commerce. The process for applying for this license is quite similar to the federal importers permit. For consistency purposes, below is a reprint of the code section establishing the requirement for this license.

§ 1.22 Wholesalers.

  No person, except pursuant to a basic permit issued under the Act, shall:

(a) Engage in the business of purchasing for resale at wholesale, distilled spirits, wine, or malt beverages; or,

(b) While so engaged, receive, sell, offer or deliver for sale, contract to sell, or ship in interstate or foreign commerce, directly or indirectly or through an affiliate, distilled spirits, wine, or malt beverages so purchased.

  Both federal permits, if the application process is managed properly and barring any unforeseen issues, should be issued within 45-60 days.

  It’s important to note that basic permits do not expire. They remain in effect until revoked, suspended, voluntarily surrendered or automatically terminated. Automatic termination can occur by operation of law when there is an unreported change in the licensed entity. In particular, change in ownership or stock transfers, among other things, must be reported to TTB on the appropriate forms within 30 days of the occurrence. If they are not reported, the basic permit will terminate by operation of law. It is essential that any contemplated change to the business be analyzed for its effect on the license and reported appropriately if required.

  As an additional note, the foreign winery/production facility must be registered with the FDA as a food facility. A registration number is assigned and must be available at the time of importation or the wine will not clear customs.

Product Approval

  Prior to importation, certain wines may be required to go through a formula approval process conducted by the TTB laboratory, though most do not. Generally, if there are added ingredients including flavorings, formula approval process is required. However, most wines produced and containing only grapes should not require formula approval. Other alcoholic beverages such as spirits and malt must be analyzed separately, as those products tend to have a more stringent formula approval process.

Certificates of Label Approval (COLA’s)

  All imported wine labels must be submitted to the TTB prior to importation and approved. Approval results in the issuance of a Certificate of Label Approval, more commonly called a COLA, which is required to be presented to US Customs at the port of entry, along with other documents.  TTB will examine the label to ensure that all mandatory labeling requirements are met. The wine label approval process can be complex, particularly for a first-time submitter. Certain pieces of information need to be affixed and positioned according to the regulations or the label will be rejected by TTB until brought into compliance. It would be beneficial, especially for the first-time submitter, to consult an expert when commencing the COLA process.

State Licensing

  As noted, TTB regulates the importation of beverage alcohol in foreign and interstate commerce. Prior to brand introduction in any state, it is incumbent on the importer to determine which state licenses are required prior to selling the wine within the borders of that state. As a general rule, some sort of non-resident permit is required, and often times brand registration as well. This is not a one-size-fits-all model, and these writers stress that each state’s requirements be examined carefully, and the appropriate licenses must be obtained.

Getting Covered: How Cover Crops Can Work to Protect Vineyards

Cyndi

By: Cheryl Gray

Knowing how to protect a vineyard from the havoc wreaked by unknown threats is an important part of any grape grower’s toolkit.

  One of those tools is a cover crop. Many experts agree that cover crops play a vital role in guarding vineyards because they have a major impact on vine health and the ecosystem that surrounds vineyards.

  According to researchers at Texas A&M University, growing a cover crop can help reduce the use of chemicals that can adversely affect the environment. Cover crops can also reduce the physical toll on a vineyard that comes with frequent use of heavy equipment on the precious vineyard soil upon which grape plants depend. 

  Scientists at Oregon State University cite three main goals of what cover crops should accomplish when it comes to managing vineyard floors between the vines, in the headlands, around vineyard blocks and in the vine rows. Those goals are weed control, soil conservation and managing soil water. Vineyard design, age of the vines, soil type and grape-growing region all contribute to the process.

  By definition, cover crops are any plants grown in vineyard middles and sometimes under vines. They are non-cash crops and are not harvested. Generally, cover crops are planted each year in the fall and spring. They are maintained on a perennial basis. Scientists advise that using cover crops requires a thoughtful approach to reap the benefits of this organic tool.

  According to the United States Department of Agriculture, many types of cover crops are recommended specifically for vineyards. These recommendations come on the heels of field studies compiled by the USDA and its research partners.

  The list includes grasses and cereals, such as barley, annual rye grass, winter cereal rye and winter wheat. The choices for cover crops also include legumes, such as fava beans, garbanzo beans, crimson clover, hairy vetch and Austrian winter pea. There are also brassicas and cruciferous vegetables that include mustard, rape, forage radish and oilseed radish.

  Annual plants are the most frequent pick for vineyards. A major reason annual plants are chosen over perennials is to allow the cover crops an opportunity to grow and to provide seasonal soil conservation during winter. In the summer, the cover crop is tilled over, another benefit to the vineyard soil.

  Cover crops are rated according to their ability to provide either slow or fast carbon. How they produce nitrogen is also key. Cover crops that are rich in substances such as cellulose and lignin are defined as so-called slow carbon sources. Fast carbon options include grasses and brassicas that contain easily biodegradable sugars. Legumes are cover crops that provide a good source of nitrogen.

  Agriculture experts recommend using a cover crop strategy that creates a balanced mix of slow and fast carbon-producing plants and those that generate nitrogen. In this way, microorganisms can successfully degrade organic matter without choking off vital nitrogen that vineyard soil needs. The so-called “combo” meal of legume and grass provides the ideal blend because the two complement each other, providing fibrous and tsp root systems while also kicking in nitrogen for the vines.   However, in cases where a single plant species has a proven track record, experts say go with it, but keep in mind that single species plantings need to be rotated in order to fight potential buildup of insects, bacteria, viruses, fungi and other pathogens that can harm vineyard plants.

  There are other benefits to using cover crops. In addition to improving soil structure, they also help with water infiltration with their roots. Some of those roots can loosen soil up to five feet, reducing soil compaction and improving the penetration of water and air. Cover crops improve mineral fertility by helping the soil to better retain important minerals that vineyard plants need, including acting as a guard against minerals leaching. Cover crops can store vital minerals during winter months. They also provide aesthetic value to vineyards and traction for equipment and workers.

  Another benefit that cover crops provide is that as they grow, they work to improve the biological activity and organic matter in vineyard soil. Once their leaves and other plant materials begin to decompose, they kick-start the benefits of this organic process by boosting organic matter within the vineyard soil. 

  Erosion and runoff are enemies of vineyards. Cover crops combat these problems by preventing the damage that rain can cause when it dislodges soil. They help block the growth of weeds by preventing them from germinating in the first place. They also provide a welcome habitat for vineyard-friendly insects and predators. 

  Nematodes are also harmful to vineyards. Among the worst of these parasites are root-knot nematodes that stay in one place on the plant and lesion nematodes that travel around. Cover crops can help curb some of this threat.

  Cover crops also influence the growth of grapevines by forcing them to compete for water and nutrients in the soil. The additional nitrogen provided by cover crops also promotes the growth process.

  Managing cover crops is a process that begins with making sure that the soil is properly cultivated for good germination. Many growers opt for using a shallow tiller to get the job done. Moistening and leveling the soil follows. Then comes the seeding, which is done according to the climate of each grape-growing region. Experts say that a no-till drilling method for seeding cover crops helps conserve the texture of the soil, provides uniformity in placing seeds and helps better establish the cover crop in the vineyard. After seeding, the seed bed soil should be lightly packed with proper irrigation setup to promote germination and establish the cover crop.

  Cover crops need to be fertilized. Grasses and brassicas might need additional nitrogen for optimal growth. However, experts warn that this is where caution should be exercised because legume and grass mixtures promote increased nitrogen, which could result in too much nitrogen, resulting in too much of a good thing. Soil tests will likely be required to check the impact of any cover crops in play.

  While the benefits are many, there are drawbacks to using cover crops. Their presence may increase water use, create a frost hazard and may result in competition with the vineyard plants for soil moisture and vital nutrients. Pest problems can also result when a cover crop isn’t kept at a reasonable height. Finally, there is the chance that the use of cover crops might result increased management and cost.

  To combat the frost issue, many growers opt to mow down their cover crops in early spring, essentially using what is left for frost protection. Those cover crops are then allowed to pick up growth again before finally going to seed. Once the seed matures, the cover crop is mowed and either left on the surface or mixed into the soil with a shallow tiller.

  There is a wide range of research available documenting the results of cover crop use throughout the grape-growing regions of the United States and beyond. In addition to the USDA, many colleges and universities with curriculums that focus on viticulture have useful resources for grape growers in their regional areas. Much of the research is performed in the field through partnerships with vineyards that not only want information but are willing to share it for the benefit of other grape growers who want to know more about the pros and cons of cover crops.

Will Crop Insurance Cover Losses to My Vines?

Cyndi

By: Trevor Troyer, 
Vice-President of Operations 
for Agricultural Risk Management

Does crop insurance cover losses to my vines? What can I do about vine loss or damage?  Half of my vineyard got burned due to wildfires.  I have major freeze damage on half my vineyard.  What can you do?  Crop insurance only covers losses to your grape crop not your vines.  Is there any vine coverage or assistance for that?

  Yes there is! I get a lot of questions on this so thought to address it in this article.

  Grapevine crop insurance coverage is available for the 2025 crop year. The sign-up deadline is November 1st in all states where it is available.

  The states where you can obtain this coverage are: California, Idaho, Michigan, New York, Ohio, Oregon, Pennsylvania, Texas and Washington.  It is not available in all counties though.  The counties that are listed in the actuarial documents are not the same as the Grape crop insurance program.  This  program is available for grafted grapevines only.

  What is covered with this insurance product?  The Causes of Loss that are listed in the Grapevine Crop Provisions are below:

11. Causes of Loss

(a) In accordance with the provisions of section 12 of the Basic Provisions, insurance is provided only against the following causes of loss that occur within the insurance period:

(1) Freeze;

(2) Hail;

(3) Flood;

(4) Fire, unless weeds and other forms of undergrowth have not been controlled or pruning debris has not been removed from the vineyard;

(5) Insects, diseases, and other pathogens if allowed in the Special Provisions; and

(6) Failure of the irrigation water supply if caused by an unavoidable, naturally occurring event that occurs during the insurance period.

(b) In addition to the causes of loss excluded in section 12 of the Basic Provisions, we will not insure against damage other than actual damage to the vine from an insurable cause specified in this section

  The vine needs to be completely destroyed, or is damaged to the extent that it will not recover in the 12-month insurance period from November 30th.

  Any damage other than damage to the grapevine from an insured cause is not covered.  For example, chemical drift, terrorism etc. are not covered.  Failure to follow good farming practices or the breakdown of irrigation equipment are also not covered.

  For the grapevines to be insurable they must be adapted to the area they are being grown in.  They must be being grown and sold for fruit, wine or juice for human consumption.  The vines must be grafted to be insurable as well.  The Crop Year begins December 1 and extends through to November 30 of the following year. You must have a minimum of 600 vines per acre to be insurable also.

  Vines are classified into 3 stages of growth for the policy.  Here are the exact definitions:

(a) Stage I, from when the vines are set out through 12 months after set out;

(b) Stage II, vines that are 13 through 48 months old after set out; and

(c) Stage III, vines that are more than 48 months old after set out.

  Values are determined by the Stage (age) of the vine and the county they are located in.  Obviously Stage III vines are worth more than Stage I vines.  These prices are set by the USDA Risk Management Agency.

  You can choose coverage levels for your Grapevine insurance from CAT (Catastrophic) to 75%.  CAT insurance is 50% coverage but you only get 55% of that 50% value per vine. Coverage increments are 5%, so you have 50%, 55%, 60%, 65%, 70% and 75%.   There is a sort of a double deductible with Grapevine insurance.  You have a damage deductible and a value/price deductible.  For example, if you choose 75% coverage you would have a 25% damage deductible.  That means that the first 25% of damage is not payable.  So, if you had 30% of your vines killed because of a freeze you would have a payable claim of 5% (30% minus 25% deductible).  There is also a value deductible as well. Again, if you have 75% coverage you would have a grapevine value deductible of 25%. For example, if the grapevine is Stage III in California in Napa County it would be worth $39.  At the 75% coverage level the dollar amount for that vine would be $29.25.

  There is an optional endorsement that changes the damage deductible.  This endorsement does cost a little more but is worth it, in my opinion.  This is called the Occurrence Loss Option or OLO for short.  It changes the damage deductible to a 5% damage trigger.  If your loss is 5% or more of the total value of the vines in a unit you would have a payable loss.  Plus, you are paid on the full value percentage of the loss.  So, if you had a 30% loss, you would get paid on the full 30%.  This does not change the value percentage of the coverage level, if you choose 50% you get that amount.  You cannot exceed the total insured value, Liability, of the vines in any case. 

  Once you sign up and complete all the forms with your agent, they are then submitted to the underwriter.  The underwriter will open an inspection and an adjuster will come and take a look at your vineyard.  The adjuster will determine if the grapevines in your vineyard are insurable.  The vines could be uninsurable for any of the following reasons.  The vines are unsound, diseased or in someway unhealthy.  They could have been grafted within a 12-month period before the beginning of the insurance period. Or they could have been damaged prior to the beginning of the insurance period.  Once the adjuster has completed the inspection, it is sent to the underwriter and then on to the USDA Risk Management Agency for final approval. 

  If you have damage from an insured Cause of Loss, you should contact your agent to get a claim opened.  It is always best to get a claim opened up sooner rather than later.  48 – 72 hours after discovering damage is best.  I know that a lot of growers want to wait and see how much damage there is before they do anything.  It is always better to get a claim opened up rather than wait and see.  If there is not enough damage, then you just let the adjuster know.  After you open up a claim an adjuster should be out within 10 days to inspect the vineyard.  Do not remove any damaged vines until it has been inspected!   In my opinion this is a good program, and it will provide protection to vineyards.  It will help to mitigate losses from Freeze, Hail, Flood, Fire et

The Growth of Baco Noir Grapes in Oregon’s Umpqua Valley

Cyndi
clusters of Baco Noir grapes

By: Becky Garrison

The origins of Baco Noir grapes can be traced back to the 1890s when phylloxera decimated Europe’s vineyards by eating away at the roots of the vines. As these native grapes (Vitis vinifera) possessed no inborn resistance to this microscopic louse, they began dying.

  Conversely, grapevines planted in North America proved to be resistant to phylloxera. So, researchers began to experiment with cross-pollinating American grape varieties with European Vitis vinifera to see if they could produce phylloxera-resistant vines that would grow in Europe.

  These experiments bore fruit in 1902 when botanist François Baco (1865-1947) released a hybrid grapevine called Baco 1 (also called Baco Noir) that he produced by crossing a Folle Blanche, a French white grape used for brandies from the districts Armagnac and Cognac, with a Vitis riparia species indigenous to North America. The result was an early budding grape with small- to medium-size bunches producing high yields that were low in tannin and high in acid. This early budding made the grapes susceptible to spring frosts and resistant to powdery and downy mildews. Also, these grapes did not have the foxy characteristics that many other 50 percent of vinifera hybrids express.

  In The Wine Bible, Karen McNeil notes how this grape was cultivated in Burgundy and the Loire Valley until France officially barred all hybrids from being grown in French vineyards. Since this grape was not included in the French register of authorized varieties, its area diminished to just 28 acres, as reported in 2008 by Jancis Robinson. However, this French-American hybrid was transported to North America in the 1950s, when it became popular in cooler climates where traditional vinifera varieties tend not to thrive. Among the more popular regions where one Baco Noir is grown include Upstate New York, Michigan, Oregon, Colorado, Ontario, Canada New York State, Canada, the Midwest and more recently, Oregon, with a particular focus on the state’s Umpqua Valley.

The Birth of Baco Noir in the Umpqua Valley

  According to winemaker Marc Girardet, in 1969, his parents, Philippe and Bonnie Girardet, took off in their VW bus from Northern California, heading northward in search of a place where they could live off the land and raise a family. Upon discovering Oregon’s Umpqua Valley, they purchased 54 acres of old sheep pasture and built a cabin.

  Over a bottle of wine in 1971, this Swissman-turned-Oregonian and his wife decided it would be fun to plant a vineyard. As there wasn’t much vineyard rootstock available in Oregon, they decided to search far and wide. Somehow, they made connections on the East Coast and discovered the Geneva, New York experimental hybrid grapes, along with the French-developed hybrid grapes such as Baco Noir and Marechal Foch.

  Philippe quickly seized onto these hybrid grapes because they could be grown naturally without the need for mildew or mold sprays. After a few road trips back east, they returned with a plethora of hybrid grapes, which would quickly become the largest collection of their kind on the West Coast. Throughout the 1970s and 1980s, they grew these grapes in the family vineyard, along with some wild varieties like Landot Noir, DeChaunac and Chancellor.

  Initially, these varieties were mostly blended until 1990 when Philippe noticed Baco Noir grapes had more of a spicy, juicy, yet smooth flavor that stood out above the other hybrid grapes. So, he bottled this grape on its own. Marc recalls helping him sell the first bottles at several wine festivals in the mid-1990s. As he recounts, “The sales pitch was half  ‘Hey, look at this cool wine we made with grapes that aren’t sprayed with any chemicals’ and half ‘try this great wine, and see how amazing it tastes!'”

Baco Noir Grapes Pioneering Natural Wine Movement

  In Marc’s estimation, his father was quite a bit ahead of the curve with the natural wine angle because it didn’t really seem like anyone was aware or cared about natural wine back then. “This wine became a sensation based more on its smooth flavor profile than anything else,” he reflects.

  From the beginning, they chose to farm naturally without any pesticides and using locally sourced horse manure compost. They also chose to practice dry farming, as that practice maintains a small berry size while developing a deep root system. Post-harvest, the grapes are hand-sorted and then de-stemmed into open-topped vats. Next, Girardet hand-punches the grapes to produce a wine that is lightly pressed and racked to barrel for aging.

  The fruits of their labor can be seen in their 2007 Girardet Baco Noir, a vintage recognized by Matt Kramer in The Oregonian as one of Oregon’s best wines (May 31, 2009). He described Girardet Baco Noir ‘Southern Oregon’ 2007 as “a superb red wine: supple, smooth-textured, and with an uncommon refinement that makes it ideal for all sorts of red meats, salami or even just a good liverwurst sandwich.” Following this review, Girdet’s Baco Noirs continue to sell out.

  In Marc’s estimation, “There may be increased interest in Baco Noir (and some other hybrid grapes) because there is more awareness of the dangers of pesticides that traditional vinifera grapes are usually sprayed with. So maybe current knowledge has finally caught up with where Dad was in the 1990s.”

Growth of Baco Noir in Umpqua Valley

  Tyler Bradley, winemaker at Bradley Vineyards in Elkton, credits Philippe for the growing interest in Baco Noir in the Umpqua Valley. Phillip convinced Bradley’s father to plant these grapevines, citing this region’s cold climate as an ideal location to produce these bold reds. So, his father planted one acre, proving Philippe’s prediction was on target. Also, this grape proved very easy to grow once the vines were established, as it requires very little to thrive aside from some basic nutrients.

  Typically, Baco Noir grapes do not express the distinctive foxy aromas and flavors of other Vitis riparia varieties. Instead, they possess rich fruit tones, such as blueberry and plum. That said, Marc opines that even Baco Noir tends to be a little foxy. “This comes from the Vitis riparia in the genetics but is also the reason it is naturally mildew resistant. The foxiness can be appropriately minimized if the vines are grown on sunny, dry site that controls the vigor and if the wine is aged on some good oak for long enough.”

  Baco Noir tends to be constantly a few brix higher than Pinot Noir, a difference Bradley views as crucial to achieving the jamminess his customers prefer. As wine’s acidity remains very high until about 26-27 brix, this wine needs yeast with high alcohol tolerance to ferment to dry.

  Following Girardet and Bradley’s success with Baco Noir, Mike Landt of River’s Edge Winery in Elkton released a 2013 River’s Edge Baco Noir. The grapes for this wine came from the block of River’s Edge Baco Noir, which used to be a horse pasture and contained soil rich in nitrogen. This resulted in more vigorous vines that produced wines with more meaty and savory qualities.

  During this time, Melrose Vineyards (Roseburg, Oregon) began producing Baco Noir and was the first to explore making a fortified wine using the Baco Noir grape. Select winemakers also produce a Baco Noir rosé and use it in creating full-bodied red blends.

  Also, Stephen Williams, owner of Trella Vineyards (Roseburg, Oregon), paired Giradet’s Baco Noir with pizza for many years before he made Trella’s 2022 Pugilist Baco Noir using fruit sourced from two vineyards located in Elkton: Anindor and Elk Valley. He chose the term “pugilist” as it is a dated word for a fighter in a boxing match, which speaks to how Baco Noir is a “punchy” red wine. In addition to pizza, Baco Noir pairs very well with barbecued meats and other hearty fare.

By: Shana Orczyk Sissel – Founder, President & Chief Executive Officer of Banríon Capital Management

In a time period marked by the unpredictable swings of traditional markets, many investors are turning their attention to more tangible assets that provide not only financial returns but also offer a personal and luxurious experience. Among these alternatives, fine wine is becoming increasingly appealing. As a long-time observer and participant in the alternative investment space, I have seen a significant uptick in wine investment interest, particularly among investors aiming to diversify their portfolios while adding a uniquely personal touch.

Why Wine?

  The appeal of investing in wine is layered and robust. Historically, fine wine has shown remarkable resilience in the face of economic downturns, often outperforming traditional stocks and bonds during inflation and market instability. This resilience is largely due to wine’s status as a luxury item, with its value driven by limited supply and increasing global demand. The finite production of certain vintage wines means that as bottles are consumed, the remaining ones become rarer and potentially more valuable. This positions wine not just as a hedge against inflation but as a compelling means for capital preservation.

Wine Fundamentals for Investors

  For those new to wine investing, understanding the fundamentals is crucial. Key factors to consider include the reputation of the vineyard, the quality and rarity of the vintage, and proper storage conditions to preserve the wine’s value. Investing in wine requires a strategy for buying, storing, and eventually selling:

●     Selection: Focus on well-known regions like Bordeaux, Burgundy, and Napa Valley, which historically produce wines that appreciate in value.

●     Storage: Proper storage is critical and should be in a climate-controlled environment to protect the wine’s quality and longevity.

●     Insurance: Like any valuable asset, wine collections should be insured, especially as their market value increases.

●     Exit Strategy: Knowing when and how to sell is as important as knowing what to buy. Most fine wines reach a peak market value at a certain point of maturity.

Personalization at Its Best

  Investing in wine is a deeply personal experience. Each bottle has its own story, tied to its origin, vintage, and the subtleties of its taste. This personal dimension allows financial advisors to engage with their clients on a deeper level. Offering wine as dividends, for instance, instead of traditional cash payouts, forges a more meaningful connection between investors and their investments. Imagine the moment of pride an investor feels when uncorking a bottle from “their” vineyard’s wine while entertaining at home.

Strengthening Relationships

  For advisors, the wine industry offers a distinctive way to deepen client relationships. Discussing wines, sharing tastings, and exploring vineyards can be powerful relationship-building experiences. These interactions allow advisors to connect with clients in settings that extend beyond conventional business environments, fostering a sense of camaraderie and shared interest.

  In the same vein, effectively marketing a vineyard or winery to financial advisors can enhance these relationships further. Invite advisors to your property for tours, tastings, and in-depth discussions about your production process and business philosophy. When advisors are familiar with a vineyard’s story, its commitment to quality, and its unique offerings, they are better positioned to recommend these investments confidently to their clients.

Diversification Through Wine

  Wine offers substantial diversification benefits. Its low correlation with conventional financial assets like stocks and bonds means it can help smooth out portfolio volatility, providing steadier returns over time. Incorporating wine into an investment portfolio can act as a buffer against market swings, appealing to those seeking more stability in their investment journey.

Avenues for Investing in Wine

  There are several options when it comes to investing in wine, each offering unique benefits and risks. Direct ownership of bottles or cases is the most traditional method, providing control over selection and requiring knowledge of wine regions and proper storage. Alternatively, wine funds offer ease through professional management, though they lack liquidity and involve fees. Those preferring a more traditional market approach might consider wine stocks, which involve investing in publicly traded companies related to the wine industry. Wine futures, or “en primeur,” allow investors to buy wine before it is bottled, potentially at lower prices, but this comes with its own set of risks related to market and production quality.

  Emerging trends like wine exchange platforms and crowdfunding are modernizing wine investment. Exchange platforms provide transparency and liquidity, enabling the trading of wine much like stocks. Crowdfunding platforms let investors buy shares in vineyards or wine projects, reducing the barrier to entry and allowing participation in potential profits from wine production without substantial upfront investment. We work closely with advisors to help them tailor and better understand the investment options that work best for individual clients.

Seizing Opportunities in the Regulatory Landscape

  Recent shifts in regulatory frameworks have opened new avenues for winemakers and investors. With the ability to raise capital from the public more freely than before, vineyards and wineries can now explore new ways of funding their operations and expansions. However, despite the high demand, there are surprisingly few wine funds available, offering a niche yet potentially lucrative investment opportunity. A thorough understanding of the market and regulatory environment will ensure investors can identify and capitalize on the best offerings.

Targeting a Broader Investor Base

  The demographic of wine investors is expanding, with women in particular drawn to the combination of cultural appreciation, luxury, and investment potential that fine wine offers. Wineries have a significant opportunity to cater to this demographic, especially at tastings, which predominantly attract couples and women. Additionally, social media has introduced new marketing channels that are not only more cost-effective compared to traditional advertising channels like television, but also resonate strongly with the female market. Influencers can provide a personal touch and create authentic connections with products, while “mom memes” underscore wine’s cultural integration.

Global Market Trends

  The global wine market is experiencing significant shifts, influenced by changing consumer behaviors and economic conditions. According to Spherical Insights, the global wine market size is projected to reach $583 billion by 2032 with a compound annual growth rate of 5.7%. Emerging markets, especially in Asia and parts of Africa, are developing a robust appetite for luxury wines driven by increasing wealth and a growing middle class. As a result, demand is likely to keep rising, potentially pushing prices higher in well-established and emerging wine markets alike.

  In Europe and North America, consumption patterns are stabilizing, but the interest in high-quality, sustainable, and boutique wines is growing. This shift towards premium products supports higher price points and can enhance investment returns.

The Future of Wine Investing

  The future looks promising for the wine sector. As awareness of its benefits grows, more investors are likely to explore how wine can complement their portfolios. For newcomers, starting with a reputable wine fund can provide a secure and enlightening entry into the market, combining financial benefits with the pleasure of ownership.

The Last Sip

  Wine investing extends beyond simple asset acquisition; it’s about embracing a lifestyle and crafting a portfolio that mirrors personal tastes and passions. For those eager to incorporate sophistication and personalization into their investment strategy, wine offers an enticing path. Whether you’re a seasoned collector or new to the world of wine, the right investment strategy can transform every sip into not just a taste of exquisite craftsmanship but also a toast to financial prosperity.

  For a long time, wineries have used technology to produce excellent wine. These technologies include tank sensors that offer real-time data on oxygen levels, temperature and sugar content. As wine regions face challenges like labor shortages, increasing temperatures, wildfires and drought, some winemakers are looking towards smarter technology to secure their future.

  Modern vineyard owners are increasingly turning to agriculture technology (AgTech) solutions to help keep up with the pace of global wine demand. A wide variety of factors have made the grape growing job more complex and challenging, along with climate change and labor shortages, rising costs and a decreased interest in viticulture as a career. Digital tools for monitoring soil health, weather patterns and grapevine vitality are a necessity for modern vineyard operators.

  Advancements in AgTech are responsible for smarter harvesting, the electrification of equipment and better data collection in order to make more informed decisions. Plus, advances in global connectivity have improved data communication speeds, even in extremely rural or hillside locations where vineyards are often located.

  One of the AgTech solutions that is picking up a great deal of steam is precision agriculture, which relies heavily on technology to more accurately and efficiently complete winery tasks. To better understand vineyards through data, wineries are installing weather stations, soil moisture and temperature sensors and flying drones with infrared technology to gauge the health of their vines.

Improved sensor technology ultimately leads to better, more precise results for growers, including better equipment positioning and monitoring.

  Viticulture requires a great deal of energy and resources, and precision agriculture aims to use that energy and those resources more effectively and efficiently for the betterment of all. Modern wineries rely on technology to elevate the art of grape growing with automated and sustainable solutions.

Technology Enables Evolution

  The transition from traditional practices to a more modern approach has become more than necessary for vineyard operators. With the global wine market projected to reach over 450 billion by 2028, staying competitive in this industry requires an equal blend of tradition and technological innovation. While most grape growers and vineyard staff do the cultivation work like pruning or leafing by hand, the data and new technologies help them know which plants need special attention.

  Over the following decades, connectivity solutions have continued to improve, enabling faster data transfer for both cloud and edge computing globally. Additionally, the capabilities of autonomous solutions have accelerated in recent years, such as improvements in optics processing, the growth of artificial intelligence and the introduction of solid-state LiDAR—all of which add up to advancements for precision agriculture.

  In order to realize its full potential, precision agriculture requires a robust foundation, which often means a deep well of data points. That data is collected and measured by a wide variety of hardware and software solutions.

  Today, sensors are one of the most heavily used hardware solutions in agriculture – they are essential to gathering data to inform decision-making. These sensors are incredibly rugged and able to withstand many environmental factors such as high and low temperatures, extreme weather, chemical exposure, dirt, vibration, animals and much more.

  Also, the sensors used in most agriculture equipment are not only designed for wear and tear but in terms of equipment design, they are typically well-protected and hidden in hard-to-disturb places.

  Improved sensor technology ultimately leads to better, more precise results for vineyard owners, such as better equipment positioning and monitoring, better moisture and sunlight detection and much more.

Reaping the Benefits

  The search for vineyard efficiency has produced a wide range of systems and techniques in recent years. Sensor technology can help wineries function effectively and efficiently by providing real-time data on vineyard conditions.

sensor at use in vineyard

  Sensors are among the most heavily used hardware solutions in ag settings – they are essential to gathering data to inform decision-making.

Some of the most commonly used applications of sensor technology in vineyards include:

•   Soil moisture: Measures water levels to prevent overwatering/underwatering.

•   Temperature and humidity: Providing climate information to optimize growing conditions.

•   Sunlight exposure: Measuring sunlight vines receive to optimize grape maturation.

•   Spectral imaging: Captures and analyzes reflected light from plants to provide information about their health.

•   Early warning systems: Monitor wind speed, leaf wetness and rainfall to sense and communicate disease risk.

  As technology continues to scale and evolve toward precision and adaptability, vineyard owners will reap the rewards, which range from increased land productivity to less reliance on manual labor and staffing, as well as positive environmental impacts from using fewer inputs.

The Future of AgTech

  The modern viticulture industry is tasked with creating more wine while reducing environmental impacts and navigating labor shortages. Advanced technology solutions can help vineyard owners and staff automate the critical processes crucial to reaching the scalability needed to satisfy demand.

  Of course, implementing new technology can come with its own set of challenges. To enable mass adoption of precision agriculture, technology providers must be prepared to scale solutions easily and cost-effectively across the globe, and connectivity solutions must continue to improve in order to enable real-time processing and analysis. 

  Many different precision agriculture and viticulture technologies have applications in the vineyard, such as global positioning systems (GPS), robotics, airborne remote sensing, geographic information systems (GIS), digital elevation models (DEM), high-resolution soil surveys, wireless sensor networks and more.

  In an industry already facing financial pressures for an inconsistent and costly labor supply, the good news is many entry-level sensors and networking equipment costs are relatively low compared to what was available only a few years ago. The financial barrier to entry is also helped by eliminating or reducing costs in many areas, such as purchasing fewer chemicals and avoiding waste, hiring less human labor and identifying specific plants or sections that need the most attention, saving time and effort.

  As more viticulture operations embrace technology and automation, companies like DigiKey are making solutions more accessible to engineers who are building the next generation of AgTech.

From generation to generation, technology will continue to evolve rapidly and adapt to current and future needs, improving the adoption rate of precision agriculture. Vineyard owners and grape growers alike need to adopt technology to remain competitive, especially when the technology can help solve and streamline a myriad of elements of the process.

  By focusing on farming insights and automation at the plant level, the world can not only farm better, but farm different.

The Importance of Detecting Disease Before Planting

Cyndi

The summer and fall are the seasons for vineyard managers and winemakers to start to plan for new vineyard development.  Since late summer to fall is the busiest with harvest, why not get a head start?  Furthermore, the best time to scout the vineyard and observe symptoms associated with diseases is in the summer and fall seasons.

  My philosophy is if you wish to develop a healthy vineyard you need to plan ahead.  When planting a new vineyard, unless you are willing to take whatever is left at the nursery (not recommended), you will need to place your order with a nursery at least one year ahead of the planting season.    With so many different diseases that are not regulated by certification programs, I recommend you hire a knowledgeable plant pathologist (consult with me!) to help you determine the best time to perform vineyard block and vine inspections as well and how and when to collect plant and soil samples for pathogen detection.

Diseases Originate in the Vineyard

  Growers must be aware that many grapevine diseases can generate in the vineyard.  If a grower is replacing a vineyard, leaving the land fallow (with no vines) for a long period (2-3 years) may have advantages.  If the vines removed were infected with leafroll (GLRaVs) or red blotch (GRBV), it will be important to take some precautions. Some species of leafroll associated viruses (GLRaVs) are transmitted by mealybugs and GRBV is transmitted by the three-cornered alfalfa hopper. It is important to be careful when removing vines, as portions of infected roots can remain in the ground and be a source of reinfection.  When mealybugs are present in the vineyard block, these will be able to transmit the viruses to the new vineyard.   In this situation, it would be impossible to determine if the symptoms in the vineyard are due to a newly vineyard planted with infected material or if it became infected by mealybugs that remained in the vineyard unless there is a priori testing data.   I am always asked to “play detective” but without prior knowledge (i.e., testing prior block or the incoming plantings), it is a difficult proposal.

  Agrobacterium vitis (the crown gall causal agent) and some fungi are soil borne pathogens and can be propagated in nursery material as well as field selections or be present in the soil prior to planting.   Agrobacterium vitis and a diverse group of fungal pathogens are present and sometimes latent (no symptoms are visible) in vineyards.  For example, the crown gall disease agent can be present in certified planting material without showing symptoms until a stress factor (physical or freeze  damage) occurs. The stress caused by the grafting process is enough to induce typical galling if pathogenic strains of Agrobacterium vitis  are harboring withing the sourced vines.  Grafted vines commonly display excess callus formation, enlarged graft unions, and galls.  Some symptoms are typical of crown gall disease while others could be difficult to diagnose visually.   To be safe this type of planting material should be analyzed at a laboratory as it may not be easy to distinguish between bacterial galling and callusing during the grafting process (the nursery will probably claim that what you are seeing is callus but this is not always the case). 

Traditional Diagnostic Methods May Fail to Detect Certain Pathogens

  Testing the vines and soil before planting will give an indication of the type of fungal and bacterial organisms present.  Depending on the method used for testing, information of beneficial microorganisms and nematodes present in the vineyard soil can be obtained.

  Traditional methods such as microbiological culture for the detection of Agrobacterium and fungal pathogens may fail to detect these pathogens in the laboratory.   While microbiological culture in plates with identification using microscope and/or further biochemical and molecular characterization are still being used, there are some important drawbacks to these methods. The plating of microbes is prone to competition between different fungal and bacterial species.   Generally, the microorganism that grows faster will be identified but may not necessarily be the cause of symptoms of disease.  Even when a more specific method is used for identification (i.e., polymerase chain reaction), the method may not be specific enough to characterize the fungi and bacteria.  For example, there are many Agrobacterium vitis stains that are non-pathogenic and do not cause crown gall disease. 

Next Generation Sequencing as a Virus Discovery Tool

  The next generation sequencing (NGS) technique also known as high throughput sequencing (HTS) or deep sequencing is able to determine the complete sequence of the genetic material present in a vine.  The data obtained is analyzed with software that is able to compare sequences available in a database and provides a list of the bacteria, fungi, or viruses present in a given sample.  The method can provide relative quantitative data (copy number) of the presence of each organism found.

  Initially, the NGS method was used as a tool to discover new plant viruses.  In 2011, NGS lead to the discovery of the first DNA virus to infect grapevines, Grapevine vein clearing virus a Badnavirus associated with severe vein-clearing and vine decline syndrome in Missouri.  Subsequently, NGS has allowed the discovery of other DNA viruses: such as GRBV, Grapevine Geminivirus A, Wild Vitis virus 1, and many grapevine RNA inhabiting viruses (e.g., Grapevine virus E, F,G, H, I, J, K, L, M, N, etc.).  The application of NGS will continue to allow for the discovery of new viruses.  Clearly, the biological capabilities of the newly discovered viruses must be studied to determine if they pose a threat to vineyard health.

Next Generation Sequencing as a Diagnostic Tool

  Recently at the 20th ICVG (International Council for the Study of Grapevine Viruses and Virus-Like Diseases) held last year in Thessaloniki, experts discussed the application of NGS (aka HTS) technology for diagnostic purposes.  Comparative studies have allowed replacing the woody index technique with NGS in quarantine programs.  For example, the NGS technology is already being applied for the verification of clean planting stock as well as exclusion of infected material in new variety introductions quarantine and certification programs in Italy and USA. 

  Commercial laboratories offer the testing of soil and plant tissue using NGS technology to detect bacterial and fungal pathogens in soil,  planting stock material and established vineyards. 

  The NGS technology has become a powerful diagnostic tool but requires technical knowledge and expertise to interpret the results. Because of the complexity of the results, expertise is needed to determine which of the microorganisms present in the tested material might be damaging to the vineyard health.  I have experienced receiving loads of data (enormous lists of fungi and bacteria) to sort out and determine the relevance of the findings.  The information has allowed me to help clients make informed propagation, planting, and managing decisions.

  Future research will allow us to answer what is a pathogen copy number required to initiate infection and cause disease.  In my opinion, grapevine growers and winemakers will benefit when the NGS technology is widely applied to grapevine testing.  The application of new technologies will increase the health of planting material and subsequently decrease of presence of harmful pathogens in planted vineyards and ultimately increase wine quality.  I envision that in the near future the NGS technology will allow certification programs world-wide to exclude pathogenic bacterial, fungal, and viral species from their foundation blocks.

In Season Nutrient Management

Cyndi

By: Kirk Williams, Lecturer-Texas Tech University

Nutrient management is a critical practice to have a healthy and productive vineyard.  Nutrition management in grapevines is a long-term process where nutrients can be added over time and the effects of these additions monitored over time as well.   Grapevines do not require large amounts of nutrients and the nutrients can be added in response to needs identified by soil and tissue samples

  While soil samples can give us great insight into the soil at a vineyard site they do have limitations in established vineyards.  Grapevines have a deep and extensive root system that can exist at deeper depths than common soil testing equipment can collect from.  Also, soil tests indicate relative availability and this level is not always reflected in nutrient status of the grapevine.  Soil testing in vineyards should still be done in established vineyards but a sample every three to five years is adequate to understand what is happening in your vineyard soil. 

  In season nutrient management begins with assessing the nutritional status of the grapevine.  The most common way of evaluating the current nutritional status of grapevines is through tissue analysis.  Tissue samples can be taken at bloom time or at veraision.  Sampling could also occur at both bloom time and veraision which can help you assess your in season nutrient management program.   Areas where observable problems exist should be sampled separately from areas where growth is normal.

  Tissue samples have historically been petioles but recently whole leaf samples have been utilized.   Collecting a good representative sample is critical to getting accurate results.  If you are collecting petioles, you will need 50 to 100 petioles from each block. If you are collecting leaves you will need 25 leaves per acre up to a maximum of 300 leaves per block.  Many laboratories will wash tissue samples but that will require quick shipping. 

  So, it may make sense to wash your own samples.  A few drops of phosphate free liquid detergent can be added to a basin with distilled water.  Samples should then be rinsed with distilled water for no more than 10 seconds.  Rinsing longer than 10 seconds may wash out some of the nutrients.   Samples can be dried and then shipped to the lab for processing and testing. 

  Oftentimes soil and tissue tests are deemed precise because they are actual numbers determined by a lab.   While they were determined by a lab, there are many factors that go into a fertility program for a vineyard.  There are not many black or white, right or wrong answers in vineyard fertility management. There is only a continuum of possibilities all of which are impacted by the environmental conditions of the year, the soil, the microbial population in the soil, fertilizers applied, cover crop interactions as well rootstock and scion responses to all of the above.   

  For example, in an extremely dry year, even with adequate boron in the soil and foliar applied boron, your plant tissue samples may show you are short on boron.  Low soil water status reduces boron release from organic matter and boron uptake through reduced boron transport that occurs by diffusion and mass flow to absorbing root surfaces.  The next year, under normal soil moisture conditions, your tissue samples may show adequate boron even though you did not fertilize with boron.   

  Use the soil tests and tissue tests as guides over time for your fertility program but don’t focus too much on the actual numbers, focus on the trends.  Also, don’t forget to use your eyes to see the impact of your fertility program.  

  Generally, nutrients needed in large quantities, such as Nitrogen and Potassium, are applied to the soil.  Nutrients needed in small quantities such as zinc and boron can be effectively applied to the foliage of grapevines.  We will focus on foliar fertilization for the rest of this article.  Boron and zinc can impact fruit set if they are low and are recommended to applied prior to bloom.  This timing is usually critical for prevention of many fungal diseases and these nutrients, if needed, can easily be added to a pre-bloom fungicide spray. 

  Each individual nutrient capabilities for mobility within the plant can impact how effective a foliar nutrient application is.    Mobile nutrients such as nitrogen, magnesium, phosphorus and potassium are moved in the phloem from the older leaves towards the growing tip.   Deficiency symptoms will therefore occur on the older leaves.  Immobile nutrients, such as boron, calcium and iron, are not moved around in the phloem.  Deficiency symptoms will occur in younger leaves near the shoot tip. 

  In addition to nutrient mobility within the plant, nutrients can differ in their absorption through the leaves.  Rapidly absorbed nutrients include the urea form of nitrogen, potassium and zinc.  Moderately absorbed nutrients include calcium, the sulfate form of sulfur, phosphorus, manganese and boron.  Slowly absorbed nutrients include magnesium, copper, iron and molybdenum. 

  Zinc is a nutrient that is partially mobile and is rapidly absorbed through the leaves so it is a good candidate for foliar fertilization.  In contrast, iron is immobile in the plant and is slowly absorbed through the leaves so Iron is a not a good candidate for foliar fertilization. 

  Best practices for foliar fertilization include application during the cooler parts of the day, including a high-quality surfactant, good coverage of the grapevine especially the undersides of leaves and applications to young actively growing tissue. 

  Nutrient management in grapevines is an important management tool in having a productive vineyard that produces high quality fruit.  Regular tissue sampling is required year after year to get feedback on your nutrient management program to fine tune nutrient applications to each vineyard site.  Foliar nutrient applications can be an effective management tool especially for micronutrients.

Blu Dot Farm & Vineyard

Small Batch Wines With Big Personalities

Blu Dot Farm & Vineyard's patio with chairs, umbrellas, a small travel trailer and their rows of vineyards

By: Gerald Dlubala

Blu Dot Farm & Vineyard is a boutique farm, winery and vineyard with a notable history and a bright future. Nestled between the shores of Lake Charlevoix’s and Lake Michigan with terroir directly influenced by the Great Lakes and historical glacial drift, it happens to also be the ideal place to grow great grape varietals. The estate vineyard stretches over approximately eight acres and is owned by Jennie and Paul Silva. Its 5,000 vines are personally attended to by the Silvas and General Manager Samantha (Sam) Smiertka. Blu Dot’s balanced, hand-crafted collection of wines features primarily dry selections and provides an excellent showcase for northern cold-hearty varietals.

  Blu Dot Farm’s history and main barn structure go back to the late 1800s. Originally an asparagus farm, it’s not uncommon for visitors to still see asparagus growing alongside a nearby bike path. Legend states that the farm is named after the original farmer’s son, whose first word was blue. The mid-1960s brought horses into the mix when the farm was used, and very well known for, breeding and training horses for harness racing. As a result, a primary residence, stables, barns, and half-mile racetrack were added to the property.

A Trip to Napa Sets Off a Chain of Events

  Jennie and Paul Silva fell in love with the idea of growing grapes after a trip to Napa in 2006. After returning home and researching vineyards and grape growing, they found that the Northern Michigan terroir was ideal for grape growing. If they needed another sign that they should start a vineyard, the property across from their cottage, already named Blu Dot Farms, became available. It was an unused horse farm in some disrepair but possessing a great history. The Silvas were interested not only because it was a great place to grow a few grapes but also because it was a great property on its own, a place where people once gathered, entertained, and made lifelong memories. It longed for attention and someone to bring it back to life and preserve it in a way to be once again enjoyed and appreciated by others.

  “We decided to initially plant just a few vines, see what happens, and maybe sell some grapes,” said Jennie. “After meeting with other area vineyards, we found that there was actually a shortage of Michigan grapes, so our plan was to make about 10 cases of wine for our own personal use and sell the rest of the grapes. It would be a great family hobby.”

  Work began, with holes being dug for the trellises. When the hole auger broke due to all of the limestone underground, the Silvas felt like they were sitting on a small goldmine. The rocky, loam soil would provide many nutrients for their vines and impart a subtle and welcome mineral presence on the palate. The initial intentions of grape growing and winemaking as a family hobby blossomed into perhaps making the vineyard into a business. Jennie was inspired by a California vineyard that used an airstream on their property for guests and as a tasting room, thinking it would also be perfect for their vineyard.

  “We didn’t want to overinvest,” said Jennie. We just thought that we’d see if this thing gets legs, and if it does, then maybe we can keep going with it.”

  Blu Dot Farm & Vineyard was born. That’s when Smiertka answered an ad and entered the picture.

  “Sam has really met and exceeded all expectations regarding what we were hoping for and wanting in a GM,” said Silva. “She got us to where we are today and has put us in a great position for future growth and success.”

Party Girls Partnership Leads To Success

  Blu Dot Farm & Vineyard’s General Manager, Samantha (Sam) Smiertka, is originally from Delaware. She left a career in graphic design to follow her love and passion for grape growing and winemaking. While on an apprenticeship with a local winemaker and vineyard owner/manager, Smiertka ran their tasting room and handled their marketing functions. After this apprenticeship, she made her way across the United States, building experience and skills in the industry.

  “After that initial experience, I made my way out west and accepted a contract position in Oregon as a winemaker,” said Smiertka. “When I wanted to further explore new wines and styles, I found an employment listing for a startup wine brand and applied. That startup wine brand was Blu Dot, and here we are.”

  Saying that was the start of something big would undersell the relationship. Each individual vine gets specialized care throughout its growing cycle. The vineyard is regularly walked to ensure the vines are healthy and happy. Jennie also spends quality time talking to her vines, which the vines reportedly love.

  Now, Smiertka and Silva are affectionately known as the Blu Dot Farm’s Party Girls, always ready and willing to meet, raise a glass with, and educate their guests on the awesomeness of Northern Michigan grapes and wines.

 These Small Batch, Northern Michigan Wines May Surprise You

  Blu Dot’s wines tend to be more acid-forward, floral, citrus, white wines, and then cooler season, full-bodied reds.

  “We have two sparkling wines and 5-6 dry-style, still wines,” said Smiertka. “The sparkling wines are our fun, party-girl wines, and we offer a Brut Rosé, Rosé, Marquette, Auxerrois, and Itasca, which is new to the area.”

  “Our climate and terroir parallels many of the great winemaking regions in Europe,” said Smiertka. “There are a lot of hybrids and cold hearty varietals that can grow and excel here, including Riesling and Pinot Blanc. We currently have Marquette, Itasca, Traminette, Frontenac Gris, Sauvignon Rytos, and Auxerrois planted.”

   “We’re in our fourth growing year, and currently, our annual production is almost 3 ½ tons on under three acres this past harvest,” said Silva. “We are still young, so any purchases we make are from our valued regional partners within Michigan, and we only purchase the varietals we are actively growing on the farm. We want our guests to get used to our varietals and know what to expect from us when we do start our own production.”

  Silva says that first time visitors may be surprised at the types of wines they will experience at Blu Dot Farm & Vineyard.

  “It really is fun to see the expression on people’s faces when they taste our wines,” said Silva. “It’s not the sweet style of wine that they may be expecting. And our Itasca is a wonderful, new hybrid that came out of the University of Minnesota in 2017. We’re one of the first to plant Itasca here in Northern Michigan. It’s such an amazing wine with an almost clear color. It actually looks like water in the glass, but it is so good and popular that we sell out regularly.”

  Silva tells The Grapevine Magazine that Blu Dot Farm & Vineyard is easily accessible by bike from downtown Charlevoix or Bay Harbor. They offer music, wine by the tasting, glass or bottle, and snacks to accompany their wines. A pizza oven is also being installed and should be ready to go for those wanting a specialty pizza to complement and extend their winery experience.

You’ve Found Your Peaceful, Relaxing, Happy Place

  Blu Dot Farm & Vineyard want you to be happy and relaxed in their peaceful, farm-style atmosphere. On your way into the property, you’ll weave your way through vineyards on both sides of the road until you reach the iconic vintage airstream.

  “We didn’t want to take ourselves too seriously in this whole process,” said Silva. “That’s the vibe our guests have come to know, love, and look for when they visit. The airstream serves as our main tasting room from May through October and reflects our lightheartedness and desire for a fun and memorable time. It’s specifically customized to serve and function as a bar area and tasting room, complete with popup windows, unique spaces, and interior seating for a fun and memorable experience. If guests prefer to sit outside, they’ll find comfort around our firepits with picnic tables, umbrellas, and Adirondack chairs. It’s a very welcoming and fun space to be. For colder months, a small indoor tasting room is also available.”

A Future of Self-Sufficiency

  “Well, it’s safe to say that our little hobby trip to Napa 15 years ago has become very expensive,” said Silva, laughing. “And now, our vision for Blu Dot Farm & Vineyards is all about self-sufficiency. We want to bring everything in-house and be as self-sufficient as we can. We do not do any production on-premise for now, although that is definitely part of our future plans. We also plan to expand our indoor tasting room, and within a few years, we’ll hire an in-house winemaker.”

  “And thanks to a Sunday afternoon combination of a couple of glasses of wine and picking way too many apples here on the property, we played around, experimented, and produced our first cider,” said Smiertka.

  “We made one batch that came out awesome,” said Silva. “These apple trees have been here long before us, and since cider is an increasing in popularity in our region, we hope to move forward with cider production as well.”

  “We are looking forward to a fun future,” said Silva and Smiertka. “The property is amazing, and we have the opportunity to preserve and highlight its history while adding to it. We have someone who still keeps horses here, reminding everyone of the significance of this place in Standardbred Harness-Racing. At one point, this property was home to over 300 horses. It was very well known in the equestrian world. We’d love to expand on that and add additional livestock and different animals in the future to enhance the farm experience.”

  “We continue to learn as we go,” said Silva. “Our local vineyards are very collaborative-minded. It’s amazing and rewarding that our neighboring vineyards are willing to share so much information to help us. I enjoy that type of collaborative mindset because we all want everyone to be successful and help Michigan rise to the top as a wine destination. When visitors come to our region, I see the surprise on their faces regarding the quality of wines we can put out. That quality also helps attract top talent to our area.”

  Blu Dot Farm & Vineyard offers a relaxed setting to enjoy premium Northern Michigan wine with surrounding farm and vineyard views. The vintage customized airstream can comfortably accommodate up to 12 guests and is available to reserve. Outdoor seating is always available on a first-come basis, and leashed dogs are welcome.
