Although not yet declared an AVA, the wine region boasts of many excellent Napa Valley Wineries like Farella Vineyards.The Yountville AVA has grown phenomenally in the past two decades. The climate in this region is still relatively cool by Napa Valley standards.

The region enjoys remarkably good weather, full of famous wineries, and draws a large number of tourists. Grapes grown here have distinct flavor and aroma.

Chiles Valley is indisputably one of the states's premium Zinfandel producing regions and it contains some historic vineyards that have survived the ravages of time.
