Summary: 

Do you prefer Rieslings that are floral or fruity? Or do you appreciate an Old World style of Riesling with a petrol character?
Regardless of your preference, the characteristics of the wines you enjoy come from the vineyard. Climate, site, and vineyard management practices directly impact the production of specific flavors and aromas in wine grapes.

In this session you will learn how the unique Riesling qualities you value are produced in the vineyard and how climatic variation impacts those traits.

Presenter: Justine Vanden Heuvel

Justine Vanden Heuvel is an Associate Professor in Cornell Universitys School of Integrative Plant Science. She is actively involved in both research and teaching. She co-teaches the popular Wines & Vines class at Cornell, as well as more advanced courses including Principles and Practices of Growing Grapes and Making Wines.

Dr. Vanden Heuvels research focuses on optimizing flavors and aromas in wine grapes, and improving both the environmental and economic sustainability of wine grape production systems in cool climates. In response to the broad needs of the grape and wine industry, her program has established a strong focus on multi-disciplinary and collaborative approaches.

Dr. Vanden Heuvel is widely published in the field, with some of her most recent work appearing in the American Journal of Enology and Viticulture, Journal of Agricultural and Food Chemistry, HortTechnology and the Australian Journal of Grape and Wine Research. She is currently writing a textbook intended for college-level introductory courses in Viticulture and Enology.
