    • Cornell Researchers Tackle Green Flavors in Red Wines 

      Martinson, Timothy E.; Sheiner, Justin (Cornell University, 2010-02)
      Red wines sometimes carry unwanted green flavors, attributed in part to chemical compounds called methoxypyrazines (MP) that come in with the fruit. Cornell researchers have discovered that early-season canopy management ...
    • The 2009 Grape and Wine Report 

      Creasap Gee, Jodi; Gerling, Chris (Cornell University, 2010-02)
      New York growers and vintners faced cool and sometimes rainy weather that reduced fruit set and often delayed ripening and harvest in 2009.
    • Heat and UV Radiation from Sunlight Exposure Inhibit Powdery Mildew 

      Austin, Craig; Wilcox, Wayne (Cornell University, 2010-04)
      Heat and UV light on sun-exposed leaves and clusters lowered survival of powdery mildew colonies in a five-year study by Cornell researchers Craig Austin and Wayne Wilcox.
    • Resource Assimilation and Vineyard Productivity 

      Bates, Terry (Cornell University, 2010-04)
      Viticulture is about capturing sunlight and soil nutrients and converting them into organic compounds for fuel and growth.
    • Formal and Informal Wine Sensory Evaluation 

      Mansfield, Anna Katherine (Cornell University, 2010-08)
      Anna Katharine Mansfield discusses the purposes and applications of wine sensory evaluation.
    • Increasing Customer Satisfaction Improves Tasting Room Sales 

      Gómez, Miguel (Cornell University, 2010-11)
      In a study of 12 Finger Lakes wineries, horticultural marketing professor Miguel Gomez found direct links between tasting room attributes, customer satisfaction and sales.
    • Sources and Sinks: Allocation of Photosynthates during the Growing Season 

      Martinson, Timothy E. (Cornell University, 2010-11)
      Carbon produced through photosynthesis is allocated to different tissues at different times in the growing season.
    • Improving Spray Deposition with Engineering Innovation - What a Difference a Decade Makes 

      Landers, Andrew (Cornell University, 2011-02)
      Matching airflow and liquid flow to canopy characteristics is the key to improving spray deposition and reducing off-target drift.
    • How Grapevine Buds Gain and Lose Cold-hardiness 

      Martinson, Timothy E. (Cornell University, 2011-02)
      Each year buds transition from a cold-tender to cold-hardy state through a gradual process that starts around veraison and continues through the winter.
    • Variable Eastern Weather Influences Powdery Mildew Severity 

      Moyer, Michelle; Gadoury, David; Seem, Robert (Cornell University, 2011-04)
      Heat accumulation during August-September—affecting the amount of overwintering cleistothecia that mature and survive—and water pan evaporation from two weeks pre-bloom to fruit set, are key predictors of powdery mildew ...
    • Grape Berry Moth Management 

      Weigle, Tim (Cornell University, 2011-04)
      A new forecasting model and the Grape Berry Moth Risk Assessment Protocol help growers manage grape berry moth.
    • Sulphur Dioxide Content of Wines: the Role of Winemaking and Carbonyl Compounds 

      Jackowets, Nick; Li, Erhu; Mira de Orduña, Ramón (Cornell University, 2011-08)
      Winemaking practices influence production of SO2 binders such as acetaldehyde and therefore the quantity of SO2 a winemaker needs to add during the winemaking process.
    • What Yeast Do 

      Gerling, Chris (Cornell University, 2011-08)
      Fermentation is anaerobic respiration that produces a byproduct - ethanol - that kills yeast. But in the process, yeast also transform other compounds into aroma- and flavor-active molecules that taste, smell, and feel ...
    • Automating Measurements of Canopy and Fruit to Map Crop Load in Commercial Vineyards 

      Bates, Terry; Grochalsky, Ben; Nuske, Stephen (Cornell University, 2011-11)
      Crop load - the ratio of exposed leaf area to fruit - is a key measure of vine performance. A collaborative project is using tractor-mounted imaging systems to develop crop load maps capturing variability in vine size and ...
    • Conversion Factors: From Vineyard to Bottle 

      Gerling, Chris (Cornell University, 2011-12)
      How many grapes does it take to produce a glass of wine? Cases per ton? Bottles per acre? Hectoliters per hectare? Chris Gerling explores the ins and outs of conversion factors.
    • How Close are We to Crown Gall-Free Nursery Stock? 

      Martinson, Timothy E.; Burr, Tom (Cornell University, 2012-03)
      Dr. Tom Burr's laboratory is developing improved diagnostic tests for Agrobacterium vitis, causal agent of crown gall, and screening shoot-tip cultured vines for inclusion in the Foundation Plant Service's new foundation ...
    • How Grapevines Reconnect in the Spring 

      Martinson, Timothy E.; Goffinet, Martin (Cornell University, 2012-03)
      In midwinter, buds are isolated from the rest of the vine's vascular system. Signals from the buds reactivate the vine's vascular cambium, reconnecting shoots, trunks, and roots - a process starting at budswell and ending ...
    • Small but Mighty: 'Pixie' Grapevine Speeds Up the Pace of Grape Genetics Research and Breeding 

      Cousins, Peter (Cornell University, 2012-05)
      USDA Grape Genetics Research Unit scientist Peter Cousins describes a dwarf, continuously flowering and fruiting grapevine that is a new tool for speeding up grape breeding and reducing costs associated with genetic studies.
