My SO and other are contemplating a visit to the north-of-San Fran area, with a desire to visit and tour some of the local breweries. We enjoy wine and have done some winery tours, but we are primarily beer drinkers (only quality micro-brews) and wanted to see the best for the area. In googling, I see lots of places in Sonoma/Napa, some have regular tours, some by appointment and some not at all. But what is worth seeing? A place with good food is a nice bonus. So any suggestions would be greatly appreciated. Thanks!
