Did you know that Napa Valley has over 400 vineyards? And did you know that those more than 400 vineyards produce about 4% of the state's wine? The focus here is quality not quantity.
In the town of Napa there are 18 tasting rooms within walking distance of one another. A $20 Taste Napa Downtown card gets your a pour at 13 of them. Officially the winery tasting rooms are supposed to charge you 10 cents for a taste, but most do not. Check out www.napadowntown.com for more info.
