I go to this tasting every year (always held in August – SF, or February, Pasadena), at the Festival Pavilion in Fort Mason in San Francisco. This is the premiere tasting for small family owned California producers. This is always a popular event and I recommend showing up early. The original tasting in 1991 featured 46 wineries; the 2010 tasting will have over 325 wineries!
Sunday August 22nd, 3-6pm
Festival Pavilion, Fort Mason – San Francisco
Early bird ticket prices are available through August 1
