A lot of good answers already on here. I'd like to throw out another option. If you are looking for a small, noncorporate, still family-owned, traditional winery, check out Tulocay.
Founded in 1975, Tulocay is one of the oldest Napa Valley wineries. It's also one of the smallest, and one of the most authentic. Visit the tasting room, and you won't find any gimmicks or overpriced gift shops.
Rather you'll be in for a "down home" style of tour. You'll meet the family. Tulocay wines are crafted by traditional methods. Tulocay specializes in Cabernets, Syrahs and Zinfandels, and also svelte, subtle, Burgundy-style Pinot Noirs and very classy Napa-style Chardonnays.
The tasting room is located in theAVA, just east of downtown Napa. Relative to the rest of upper Napa Valley, this area is known for its cool grape growing climate.
Check out the website,. Check out their wines. If you have any questions, just give them them call. Chances are the guy who answers the phone is the boss himself. Or his daughter. Or the dog, Buddy.
Tastings are $20 per person, but the tasting fee is applied toward any purchase. So that if you buy $20 worth of vino, no fee! The only other requirement is to give them a call in advance.
