The Carneros Wine Alliance is a non-profit association of wineries and grape-growers in the Carneros American Viticultural Area (AVA).  Carneros is the only appellation located at the crossroads of two major wine regions, the Napa and Sonoma Valleys.  Influenced by the maritime breezes and fog from its southern border with the San Pablo Bay, Carneros produces the region’s finest Chardonnay, Pinot Noir, and sparkling wines. The Carneros Wine Alliance is committed to promoting the distinction, diversity and above all, quality, of the grapes and wines from Carneros.
