Just spent a few days in the Napa valley wine tasting. Be aware: many wineries now require appointments to taste, and they charge up to $30 dollars just to sample a few wines. Some I visited deducted the tasting fee if I bought wine, others didn't. I also found their prices have gotten ridiculous. $50 for a bottle was typical of many places, and I didn't think the wine was $50 dollars good. At one winery the price of a bottle was actually a lot more expensive than the price I checked online for a store in Chicago. I think the Sonoma area is better, friendlier, and the wineries aren't nearly as taken with themselves as they've gotten in Napa.
