Potential bunch stem necrosis in Minnesota grapevines
Annie Klodd, Matt Clark, and John Thull
We have heard multiple reports of severe cluster necrosis, particularly on Marquette grapes in 2016 and 2017 in Minnesota, including here at the U of MN Horticultural Research Center. In some vineyards, it has caused substantial or complete crop loss.
Growers report that the clusters rapidly shrivel and die during veraison, while the plants and clusters appear healthy up until this point. It does not appear to be caused by black rot, mildew or botrytis. The rachis on the clusters desiccate first, followed by the berries.
This problem is still undiagnosed, however we recognize potential causes that are consistent with these symptoms. We are currently investigating it to determine the causes and extent, in order to develop appropriate management recommendations.
Knowing the number and geographic range of vineyards affected will help us address the issue most effectively. If you have experienced cluster necrosis in Marquette or another cultivar, we welcome you to contact us at kloddann@umn.edu.

One potential cause - Bunch Stem Necrosis
While the issue is currently undiagnosed, one potential cause could be a physiological grapevine disorder called Bunch Stem Necrosis (BSN). It is not a pathogen or pest problem, but rather a disorder within the plant that is caused by environmental factors. It has been documented in many different cultivars including but not limited to Cabernet Sauvignon, Riesling, Himrod, Marquette, and some experimental hybrids.
Symptoms of bunch stem necrosis
The symptoms of BSN can occur during bloom, or during and after veraison. During bloom, pedicels darken and die, causing the flowers to fall to the ground. At veraison, BSN first appears as small, dark lesions on the rachis and pedicels (stem sections of the cluster). As the lesions expand they desiccate the pedicels and rachis, causing the berries to shrivel and die.

Causes of Bunch Stem Necrosis
There are several potential causes of BSN, and they vary between individual vineyards. There is no known pathogen or insect pest associated with BSN. Rather, it is a plant physiological disorder that appears to occur following certain environmental stresses. Below are some of the possible causes of BSN based on previous research around the world. These differed between studies, vineyards, and years:
- Magnesium (Mg) or calcium (Ca) deficiency2
- Nitrogen deficiency or toxicity1,5
- Heavy and irregular rainfall during veraison3
- Below-average temperatures before bloom3
- Standing water, and “wet feet” combined with heavy soil have also been proposed
Management
More research is needed to determine the best management practices for bunch stem necrosis in Minnesota. Management will likely depend on the root cause of the issue at the site. Some studies have found that applying Mg and Ca as a soil fertilizer or foliar spray may alleviate BSN symptoms.2,4 but these results were inconsistent across instances, with other studies finding no effect. In some cases, altering pruning intensity has been found to reduce BSN.3
To address the recent necrosis issue in Minnesota and develop regional management recommendations, we hope to confirm whether the issue is BSN or another problem; narrow down the causes; and evaluate the effectiveness of various management options.

UMN Extension Welcomes Annie Klodd
Annie Klodd joined the University of Minnesota Extension in January as the new Assistant Extension Professor for Fruit and Vegetable Production. Her extension program will center on supporting Minnesota growers and improving fruit and vegetable production practices at both the commercial and home scales. She is excited to work with Minnesota grape growers and views viticulture as an important part of her program.
Annie is originally from Indianola, Iowa where her family owns a commercial vineyard and winery. She started working in the vineyard in 1997 when her family planted their first grapes, and also loves introducing customers to Midwest wines. She continued to work in viticulture as a graduate student at Penn State University, studying how perennial cover crops can be used to manage excess vine vigor. Most recently, she worked for Penn State Extension and led a national outreach program on integrated weed management. She is delighted to be returning to the Midwest horticulture industry!
Annie is conducting a needs assessment and wants your input. Along with collaborators Matt Clark and Brigid Tuck, Annie would like to capture a snapshot of the history of the grape growing and wine industry in Minnesota to help develop effective programming and to promote the industry going into the future. Come meet Annie at the MGGA Cold Climate Conference!

Keeping It FRESH: Proper Wine Storage and Maturation
Drew Horton, Enology Specialist – University of Minnesota Grape Breeding & Enology Project
One of the most important things you can do for your new wines right now is to take the proper steps to maintain their freshness. After a long year of nurturing your vines in the vineyard, and a few weeks turning their fruit into wine, now is the time to do your best to keep those wines in as optimum condition as possible during maturation and in preparation for bottling.
Maturation or aging of your wines in bulk storage is extremely important. Without proper care and maintenance, fresh, fruit-forward and youthful wine can quickly develop into a tired, oxidized and spoiled mess. There is often a misperception among novice winemakers that once a wine is fermented and racked, that merely putting the wine into barrel or tank storage will cause the wine to magically improve over time, and often for too long of a time. Though it is true that some maturation time will help the wine’s flavors and aromas to develop and “marry”, without proper control of the maturation environment a wine can change, degrade and spoil quickly.
The best friend a winemaker has at this time of year is sulfur dioxide (SO2), in the form of KMBS or potassium metabisulfite powder. There is a lot of talk going on lately about “natural wines” and the idea that the use of no or little sulfur will produce a truer or purer wine. If you are someone who likes to take chances, then go ahead and don’t use sulfur. However, if you are attempting to conduct a sustainable business that depends on a fresh, consistent, and quality product, then the judicious and proper use of sulfur is essential.
The best thing I learned while working for the world’s largest winery company is the addition of a 60 ppm dose of sulfur immediately following the completion of fermentation. That is for white wines, once primary yeast fermentation is complete, and for reds, after completion of primary and secondary (malo-lactic) fermentation. Add a dose of 60 ppm of KMBS and mix well into your wine after final transfer or racking to a storage vessel (barrel or tank).
This prophylactic high dose of SO2 will work quickly to kill or inhibit any spoilage bacteria or yeasts that may exist in your fermented wines, much like a “shock dose” of chlorine in a swimming pool.
The next considerations for the proper maintenance of stored wines are storage temperature and the need to keep vessels full. A wine in maturation-storage should be kept at 60°F or below, 55°F is best. Do your best to keep your wines in completely full vessels with little or no head-space. It is preferable to have a wine stored in various smaller vessels that are completely full than in one large vessel with too much head-space.
If you absolutely cannot avoid headspace in a vessel, then do your best to manage that space by weekly visual inspections of the wine’s surface, the regular use of an inert gas (nitrogen, argon, or CO2) to displace air (and oxygen), and to keep a proper level of free-SO2 in the wine, based on the wine’s pH. The higher the pH, the more SO2 is needed to do its job.
The reason to visually monitor the surface of a wine in storage is to ensure that no surface yeasts or molds are forming, which can lead to spoilage or increase of volatile acidity (vinegar smell). Should you notice a surface yeast or mold forming, the best thing to do is to sterile filter the wine as soon as possible to lower or eliminate the bacterial load, and to keep a proper level of free SO2 by checking it and adding it every 10 days or so.
These film yeasts can form powdery or waxy-looking surface scum on stored wine (Figure 1), and anything that is forming or floating on the surface of a stored wine should be avoided or treated. One can use a few grams of KMBS dissolved in water and applied with a spray-bottle over the surface of the wine as a way to slow-down the bacterial spoilage activity before a re-transfer or filtration.
Certainly most wines need some maturation time, and indeed some robust reds can benefit from extended barrel-maturation for up to 2 years or more, however, a stored wine is not to be forgotten. In tank or barrel storage, the wine needs to be constantly monitored and maintained with SO2. Head spaces need to be “sparged” with inert gas on a regular schedule, and a watchful eye kept on the surface of the wine. For wine in barrels, monthly topping and SO2 maintenance, and a full rack-and-return procedure once or twice a year is highly recommended.
Now is the time to take the steps necessary to insure all your work and effort will be preserved and ready to thrill your customers with your fresh and vibrant new wines.

Fall Open House this weekend!
Join in celebrating the fall grape harvest with an open house hosted by the University of Minnesota Grape Breeding and Enology project. This event will feature informal demonstrations of trellis systems used in Minnesota, a refresher on grape pests and diseases, and sampling the diversity of grape varieties and breeding lines in development. You can learn about the different research projects being conducted. Graduate student Dominique Ebbenga will give information about spotted-wing drosophila research being conducted across the state. Enologist Drew Horton will be available to answer questions about the wine making process. The open house will be from 10 am - noon on Saturday, September 9, 2017 at the Horticultural Research Center, 600 Arboretum Blvd., Chaska, MN 55318.
2013-2016 Crush Report
Minnesota Grape Production Statistics: 2013-2016
The objective of this project was to collect harvest and pricing data for 2013 through 2016. An online survey instrument (Qualtrics) was developed to capture the current production metrics, as well as estimates of yields and pricing. Additionally, growers were asked to report on the causes and amount of crop loss experienced. Grape growers were invited through email to participate in an online survey during winter 2017. Results from the study are discussed in the following link on the Extension website.

Trophy and Medal Winners for 9th Annual International Cold Climate Wine Competition
Sips, slurps, sniffs and swirls dominated the Minnesota Landscape Arboretum yesterday as 21 wine experts gathered to determine the top cold hardy wines at the 9th Annual International Cold Climate Wine Competition.
Six trophies are awarded to the top wines and wineries in addition to the medals. The top awards include Best-of-Show from each competition category, Winery of the Year, and Minnesota Governor’s Cup. Best of Show wines are chosen amongst the gold and double gold medal winners. Winery of the Year is awarded based on a weighted medal count. The Minnesota Governor’s Cup is chosen from the gold and double gold award-winning wines from Minnesota producers.
This year’s competition included 338 wines from nine states, and Ontario, Canada. The judging panel included professional sommeliers, educators, growers and winemakers amongst others.
The ICCWC is the only competition devoted to cold-hardy grape varietals. It seeks to honor and promote wines of exceptional quality produced in these unique cold-climate regions. The competition is run through a partnership between the Minnesota Grape Growers Association and the University of Minnesota.
Cold climate or cold hardy grapes are grown in regions where the better-known grapes such as Chardonnay, Merlot or Cabernet are unable to survive through the harsh weather. So in Minnesota and other northern states and Canada you will see Marquette, Frontenac, La Crescent and many other varieties. The University of Minnesota, amongst others, is a leader in breeding grapes for the harsh weather as well as suitable characteristics for winemaking.
