Washington State University Viticulture & Enology representatives showcased their research and won several awards at the 2016 American Society of Enology and Viticulture (ASEV) National Conference last month in Monterey, Calif.

WSU graduate student Eric Gale won Best Student Viticulture presentation for his talk on the “Cold Hardiness of Vitis Vinifera Roots” and Zachary M. Cartwright won Best Student Enology Poster for his analysis of penetration depths of the Brettanomyces bruxellensis yeast in varying types of oak barrel staves.

WSU professor Markus Keller and assistant professor Tom Collins gave presentations on water stress responses from grapes and sulfur compounds in winemaking, respectively.

Keller, Collins and associate professor Jim Harbertson serve on the board of directors for the ASEV.

Harbertson said WSU was integral in organizing the event and that he, Collins and Keller were part of the selection committee that decided which of the submitted abstracts were accepted for presentation at the conference.

According to Harbertson, 500 people attended the conference, primarily industry members but also a number of students and faculty from V&E programs around the country.

ASEV gave out $100,000 in scholarship funding this year, more than any previous year, he added.

ASEV holds the national conference every year, allowing enologists and viticulturists from around the world to come together for awards, research forums, student presentations and industry seminars.
