A few major recommendations combining superb wines and unique wineries some of which require reservations:

1) Caymus - attractive small sit down tasting room

2) Round Pond - Beautiful new facility tasting includes wine and food pairing

3) Hall - Make an appointment at their Rutherford facility

4) Far Niente- If someone in your party is a member of the trade

5) Patz and Hall - especially if you like Pinot's and Chardonnays

I may have some additional recommendations if you like particular varietals
