I will be visiting San Fran the week of Aug 8th-12th. I have decided to rent a car and drive up Hwy 29 to Calistoga, then back down to Napa on the Silverado Trail to visit a few wineries and then to Sonoma and hang out around the square, shop, etc and be back in San Fran to go out that night.
I have never been to San Fran as well as Napa/Sonoma. I am not a big wine drinker, but I would say that I drink more rieslings and zins more than anything. Does anyone have any suggestions as to what wineries to visit for a first time? Also, about how long to spend at each winery? Maybe a suggestion for an itinerary for the day?????
