Spanning some 37,000 acres extending into both Napa and Sonoma counties, “Los Carneros AVA” is a hot-bed for cool-climate Pinot Noir and Chardonnay wines, as well as for sparkling wines, typically produced in the traditional method. The name of the AVA means “the ram” in Spanish, and this year marks the 30th anniversary since the Carneros Wine Alliance was founded.

To celebrate, the Alliance is hosting a “Year of the Ram” birthday bash on July 25, 2015 and details are here. To help celebrate, we’re putting our educational caps on and butting heads with some hard facts about Carneros, which is a complex appellation defined by its climactic characteristics and not by political boundaries.
