I lived in the Napa Valley for 10 years and just loved it over there. Everyone who came to visit me always wanted to go tasting. . .and, so we did. Pretty soon, the employees in the tasting rooms were saying, hey its you again, out for a free buzz? Now, most of them charge per taste. I love Sterling Vineyards - take the tram up to the tasting room. Beautiful view of the Valley. And while you are at it, head up to Calistoga for some spa treatments!
