About Wine Institute

Wine Institute (WI), established in 1934, is the leading advocate for the California wine industry. Founded shortly after the repeal of Prohibition with just 42 members, WI is now an association of over 1,000 California wineries and wine-related businesses that initiate and advocate public policy. 

Notable recent successes include: opening up most states for direct-to-consumer wine shipments, creating the California Sustainable Winegrowing Alliance and growing California wine exports. Underlying all WI activities is the need to educate both the trade and the public at large. This website and companion certification program are part of that long-standing educational mission.
