We have 2 days in Napa Valley with a car - a Monday and a Tuesday, in February. Im trying to make a varied itinerary and keep in mind some nice scenery. I know I want to go to Schramberg for cave tour and sparkling wine, and also Jarvis. Im looking for one good "educational" tour +/- tasting place (?Mondavi?), and then maybe someplace smaller and someplace bigger. I was thinking of Chateau Montelena somewhere in this list. Personally I like most wines, but am a bit more of a fan of whites - so were open there. Ive read alot on trip advisor, but its difficult to make choices. Can you help? Thank you.
