Northern Sonoma

The Northern Sonoma AVA is an American Viticultural Area in Sonoma County, California, USA. The appellation covers most of the county with the notable exceptions of the Los Carneros AVA and Sonoma Valley AVA wine regions, which are located in the southern portion of the county. The creation of this AVA was largely based on the petitioning of the E & J Gallo Winery as part of their expansion of their Gallo of Sonoma brand.
