RESEARCH
Kerry Ringer’s research focuses on the impacts of winemaking techniques and viticulture techniques on the volatile compounds and volatile precursors found in grapes and wine, particularly the fruity and floral terpenes. With water and climate change becoming important issues in Washington State, she is currently analyzing the impact of extreme deficit irrigation treatments on the aroma composition of Cabernet Sauvignon grapes and wine, one of top selling varietals in Washington. Her work also focuses on the genes and enzymes involved in terpene biosynthesis.
Kerry continues to expand the methodology of the antioxidant activity method that she co-developed and is interested in the sustainable utilization of fruit and vegetable waste streams, focusing now on berries including blueberry and strawberry through dehydration, as potential sources for nutritional supplements and food powders for dry mixes.
EXTENSION
As one of Washington State’s Extension Enologists, Kerry is responsible for providing programming for the Washington Wine Industry, which now includes over 500 wineries. Her emphasis is on the education of winemakers and winery employees to maintain and improve the quality of Washington wines and the reputation of Washington as a premier producer of wine.
EXPERIENCE
Kerry Ringer has worked in the food processing, biotechnology and winemaking industries for over 10 years. She received her Ph.D. and held a Postdoctoral Research Associate position in Molecular Plant Sciences at Washington State University’s Institute of Biological Chemistry where she studied the biosynthesis of terpenes, plant compounds important for humans as aroma compounds and pharmaceuticals. Her career began after graduating from Western Washington University. She has worked for two major biotechnological companies, before she became interested in wine and food processing. In the mid-90’s, Kerry worked at Covey Run Winery when there were only a fraction of the wineries now present in the state. She has been involved in the development of a patented dehydration technology, Radiant Zone Drying, and a novel method and equipment to quickly and accurately measure total antioxidant activity. With a focused goal of specializing in the production of quality wine and food products, she has held several positions in quality control/assurance, and is currently working to define methods and analysis for measuring food quality.
