The most prestigious wine region in the U.S. just announced its first new American Viticulture Area (AVA) in 13 years. Napa Valley, already home to 17 distinct AVAs, officially added Crystal Springs to its list on Wednesday.
The Alcohol and Tobacco Tax and Trade Bureau (TTB) took over four years to approve the AVA proposal, which its author, Steve Burgess, has supposedly been working on since 2005. The last sub-region approved in Napa Valley was Coombsville in 2011.
