Some of the best Napa Valley winetasting experiences are to be had in the tasting rooms of the smaller wineries along the Silverado Trail. Envy Wines, just north of Calistoga (the northernmost part of Napa Valley), is a great pick if you want a more intimate wine tasting experience. Envy Wines is a boutique winery, meaning that it produces small amounts of its wines (just 1500-1700 cases) that are only available at the winery. It's also an estate winery, which means that all its wines are made from grapes grown on their 11 acres of land. Tasting fees are reasonable at just $15 and are waived with a $30 bottle purchase.
