I will be going for a quick 2 day trip to Napa at the end of August with my girlfriend. We are having some trouble trying to determine which wineries to visit. We are looking to book a few tours in advance (specifically one with a cave and one with just a good tour) as well as nice views and of course great wine. We are mainly interested in big Cab's and to a less extent burgundy varietals as well as one sparkling thrown in the mix. I haven't narrowed down the list (probably looking to select 4 wineries) but based on what I have read on CH:
Jarvis (Caves Tour)
Silverado (Full Tour)
Frank family Vineyeards
Stags leap family Cellars
Am I missing anything? which wineries have the best tours? Thanks in advance for everyone's help.
