Outreach Seminar – Balancing Vines and Wines from Coast to Desert

Grapes and wines are grown and made in the Pacific Northwest in extremely diverse environments.  Vine balance in Dundee, OR is not necessarily the same as in Prosser, WA, and achieving balance in wines using different varieties grown in warm and cool regions requires different viticulture and winemaking strategies. In addition, cold winter temperatures with the threat of winter injury make even greater demands on wine growers.  The goal of this seminar is to compare and contrast grapevine physiology, viticulture, enology, and winemaking practices for a cool-moist region like the Willamette Valley with the warm-dry conditions found in Eastern Washington and Oregon, and the Okanagan Valley of British Columbia.  Given that all of these regions have relatively short growing seasons, how is a shared concept like vine balance different in these diverse wine regions?
