I've been to Napa many times. The best wineries I've been to are Hess (They have a fab art collection too!), Schramsburg and Girgich Hills. They have a wonderful '95 Chard.

Hi Melanie, <BR> <BR>From S.F. you are only about 45 min to an hour away from the wine country. <BR>You could have a real nice time and see a lot on a day trip. But do your research ahead of time and have some idea where you want to go and what you want to see. <BR>I think Sonoma and St. Helena are a must. <BR>
