If you're looking for a great rose, try Unte. They don't have a formal tasting room, but if you call ahead of time and they're around, the winemaker will do a tasting with you right in their barrel/blending room. I've always been more of a red drinker than a white drinker, but we stock up on cases of their rose every summer because it's so delicious.

I also second the recommendation for Willi's Raw Bar in Healdsburg proper (but I confess to a bias--my sister was their executive chef de cuisine for about 5 years).

I finally got off my duff and started a cheese blog--now, I'm looking for recommendations on where to go for the best selection of dairy delights to try and buy. Whole Foods and Rainbow Grocery in SF have both been better-than-expected resources, but is there a west-coast version of NYC's Murray's cheese shop that I don't know about?
