If anyone is into wine, especially California wine, there is an excellent event happening this Sunday (24th) at the Fort Mason center in San Francisco. It's an industry trade event that's open to the public from 2PM to 6PM, with hundreds of wineries and literally thousands of wines available for tasting. Check out their website for more info
Family Winemakers of California

I went last year and it was pretty amazing, will be going again this year.
Cheers!
