Sulfur Residues and Post-bottling Formation of Hydrogen Sulfide
Have you ever had wine go into the bottle smelling sublime, only to emerge later on smelling strange? Graduate student Jillian Jastrzembski and Gavin Sacks, associate professor of food science, explain what can cause this, and how to reduce the risk of these off-aromas in finished wines.
Comparing Red Wine Color in V. Vinifera and Hybrid Cultivars
In V. vinifera wines, the color transition from purple-red to brick red during aging is well documented. This transition, driven by anthrocyanins, has not been documented in hybrid varieties. Claire Burtch and Anna Katharine Mansfield discuss what is known about wine color and hybrid wine composition.
Five Questions for Lance Cadle-Davidson
Lance Cadle-Davidson, Plant Pathologist for the USDA-ARS Grape Genetics Research Unit, discusses his research on grapevine fungal and oomycete pathogens and collaboration with grape breeders and pathologists throughout the U.S.
A New Crop: Viticulture & Enology MPS Alumni Successes
Graduates of the Cornell Viticulture and Enology MPS program enter the workforce with a diverse range of classroom and lab or field experience, thanks to this course-intensive, applied Master's program.
How Grapevines Respond to Water Stress
Leaf stomata open and close to regulate water vapor and CO2 exchange. When drought stress causes closure, photosynthesis and evaporative cooling stops. Prolonged deficits cause leaf senescence, ripening delays, and carryover effects.
Recap: Summer Scholars Program 2016
This summer, 29 undergraduate students from across the U.S. conducted their own research at the NYS Agricultural Experiment Station in Geneva, New York, including four diverse projects related to grapes.

IN THE NEWS
- Gil Stoewsand, who helped to save N.Y. wine trade, dies
In the 1960s, French and Germans scientists attributed hybrid wines to birth defects in animals. Gil Stoewsand, a Cornell food scientist, successfully disproved this questionable science, now considered to be one of the most important contributions of the NYS Agricultural Experiment Station to the Finger Lakes wine industry. Dr. Stoewsand passed away on July 4 in Geneva, New York.
- Vineyard cover crops save expense, environment
Research led by Justine Vanden Heuvel, associate professor in the Horticulture Section, investigates the impacts of planting different cover crops between grapevine rows as an environmentally-sustainable and cost-effective alternative to herbicide application.
- How will drought affect grape size, yield?
In this Morning Ag Clips article, Hans Walter-Peterson, viticulture extension specialist for the Finger Lakes Grape Program, discusses this summer's drought conditions in the Finger Lakes region.
