Keep a Cork in it: Stabilizing Sweet Wines for Bottling

If wine is not properly stabilized prior to bottling, microbes can grow and flocculate, as shown in this photo.

Residual sugar (RS) is an essential part of many wine styles, and in the northern varieties it can be especially useful. Depending on the titratable acidity and other characteristics, even “dry” wines may require a little RS to achieve a balanced mouthfeel. Sugar is food for people and microscopic organisms alike and in wine, unless steps are taken to ensure that the product is microbially stable, problems ranging from off-aromas to self-ejecting corks may appear.

Chris Gerling, extension associate in Cornell University’s extension enology lab, gave the Northern Grapes Project Webinar “Keep a Cork in it: Stabilizing Sweet Wines for Bottling,” in May of 2012, and discussed principles of filtration and other chemical & microbiological means of inhibiting or killing spoilage organisms, as well as the various costs and benefits.

Dec. 16 Northern Grapes Project Webinar

The Northern Grapes Project Webinar Series

“Stuck on You – Sulfur Spray Residues in the Vineyard and Winery”

Chris Gerling                     Gavin Sacks                      Jillian Jastrzembski

Tuesday, December 16th, 2014

12:00 Noon Eastern (11:00 am Central)

7:00 pm Eastern (6:00 pm Central)

Chris Gerling, Gavin Sacks, and Jillian Jastrzembski of Cornell University are teaming up to bring you this webinar on sulfur residues. In addition to must nutritional deficiencies, yeast metabolism of elemental sulfur (S) residues represents a well-understood pathway for formation of hydrogen sulfide (H2S, “rotten egg” aroma) during fermentation. Although S sprays are widely used for controlling powdery mildew, wine grape growers are often encouraged to avoid S-sprays near harvest as a point of caution to decrease the potential risk of excess H2S formation. This webinar will review i) recommendations for maximum S residues pre-fermentation, ii) winery-appropriate methods for S-residue measurement, and ii) the effects of spray formulation/rate, spray cessation date, and post-harvest decisions (e.g. skin contact, clarification) on S-residues. Recent data indicating a correlation between S-spray residues and formation of H2S post-bottling will also be discussed.

November 20th Northern Grapes Project Webinar registration is open

The Northern Grapes Project Webinar Series

“Trellis Design and Construction and Pruning Fundamentals Prior to Your First Cut”

Steve Lerch Mike White

November 20th, 2014

12:00 Noon Eastern (11:00 am Central)

7:00 pm Eastern (6:00 pm Central)

Steve Lerch of Cornell University and Mike White of Iowa State University will present a two-part webinar on trellis design/construction and pruning basics. Steve’s portion of the webinar will cover the materials, equipment, and methods used to build a sound trellis that will stand the test of time. Mike’s portion of the webinar will cover the pruning fundamentals you need to know, prior to making the first cut, that will dramatically increase the chances of reaching that ideal vine balance (aka: nirvana in the vineyard) that we all read about but seldom achieve.

Registration is NOT required if you received this email directly from Chrislyn Particka, as it means that you are a member of the Northern Grapes Webinar mailing list.

All members of the Northern Grapes Webinar mailing list will receive an email the Monday before the webinar containing the web address (URL) for both webinar sessions as well as connection instructions.

Willsboro & Keeseville, NY

You’re invited on a tour of on-going research projects and a meeting to advise the future of the cold-hardy wine grape industry in the North Country.
Cornell Cooperative Extension needs your input for determining the future of the grape industry in northern New York and Vermont! We invite you to participate in a tour of our grape variety trial at the Cornell Willsboro Research Farm followed by an advisory meeting. This meeting is open to wineries and current or prospective grape growers, interested in growing cold-hardy grape varieties.
Your input will be used to guide the future of the wine grape variety trial at the Willsboro Research Farm and Cornell Cooperative Extension’s involvement in the industry.

We are trying to capture everyone from licensed wineries and amateur and potential growers/winemakers. Participants should complete page #2 of the attached registration form and return it with their $10 registration fee to the address listed.

UVM ‘Cider apple’ research earns USDA grant

UVM Food Systems Faculty awarded USDA Federal State Market Improvement Program grant to study apple production systems to support hard cider industry.

Hard cider is big business in Vermont and across the U.S., with average annual growth of over 50% nationwide for the past five years. However, little research has been conducted in the U.S. on costs of production for apples grown for hard cider production, opportunities to reduce inputs and change management practices in cider apple orchards, or economic impact of cider apple production systems. University of Vermont faculty Terence Bradshaw, Tree Fruit and Viticulture Specialist, and David Conner, Agricultural Economist, were awarded a multi-year, $75,000 USDA grant (“Orchard Economic Assessment to Support Vermont Hard Cider Production”) to conduct that research through collaborations with commercial apple growers and cideries in Vermont. Supporting partners providing matching funds include Vermont Hard Cider Company and Vermont Tree Fruit Growers Association. Specific objectives of the project include: an evaluation of production costs to grow apples specifically for processing into hard cider; quantification of per-acre yield and fruit quality of cider-grown fruit in diverse orchard systems; identification of orchard management practices that may be modified to enhance profitability of cider apple production systems, and; calculation of economic impact on the cidery industry using different scenarios based on the results of the above objectives. The project builds on work presently being conducted by the investigators through a complementary project, “Apple Market Optimization and Expansion through Value-Added Hard Cider Production”, funded by the Vermont Working Lands Enterprise Initiative. More information on the recent USDA awards can be found here and a list of FSMIP project awards is available here.

Wine Deacidification

The effectiveness of seed crystals to reduce acidity is being evaluated in La Crescent, Frontenac, and Frontenac gris in a study at Cornell University.

photo: Chris Gerling

One of the challenges in making wine from cold-hardy cultivars is the high acid levels in the grapes.  Therefore, one of the objectives for the Northern Grapes Project Enology Team is to optimize deacidification methods for these cultivars, which has been a focal point in their research projects and outreach activities.

As harvest is either underway or complete in most of the cold-climate states, now is a good time to review deacidification strategies.  Two Northern Grapes Project webinars (Managing Acidity in the Wineryand Malolactic Fermentation) and two newsletter articles (Necessary Evil: Chemical Deacidification for High Acid Wineand Using Selected Yeast Strains to Reduce Wine Total Acidity) have focused on this topic.
