The College of Agriculture and Life Sciences at Cornell is home to one of the top viticulture and enology programs in the world and is internationally recognized for its expertise in breeding table, juice and wine grapes adapted to cool climate growing regions. From developing innovative trellis systems, to breeding new varieties, to managing pests and nutrients, to siting vineyards and maximizing ‘terroir,’ to perfecting the art and science of wine making, Cornell’s teaching, research, and extension in viticulture and enology offer unsurpassed opportunities for grape growers and wine makers, as well as undergraduate and graduate students.

  • Grape Insect and Mite Pests, 2021 Field Season 

    Loeb, Gregory (Cornell University, 2021-05-07)
    Another growing season is upon us and it’s a good time to be thinking about, and preparing for, potential arthropod pests that you might encounter this year. My goals for this review are to 1) highlight the main arthropod ...
  • 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.
  • 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 ...
  • 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.
  • 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.
  • 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 ...
  • Climate, Duration of Bloom, and the Window of Risk for Grapevine Diseases 

    Gadoury, David M.; Seem, Robert C.; Moyer, Michelle (Cornell University, 2012-08)
    Bloom and berry development is much more variable in climates with warmer winter temperatures. Extended bloom lengthens the narrow window of susceptibility of fruit to pathogens such as powdery mildew, downy mildew and black rot.
  • Fifteen Years of Vine Root Growth Studies in Concords 

    Lakso, Alan N.; Eissenstat, David M. (Cornell University, 2012-11)
    Using a miniature camera lowered into the root zone, Cornell physiologist Alan Lakso and Penn State root biologist David Eissenstat tracked seasonal growth of fine Concord roots over several growing seasons. Here is a ...
  • 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.
  • 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 ...
