Coombsville AVA is one of Napa Valley’s newer appellations, having received its official designation only in 2011. Tucked just to the northeast of Los Carneros and a few minutes’ drive east of downtown Napa, the Coombsville appellation is relatively large at a total of 11,000 acres. The elevation varies from 100 to 1,000 feet, and the climate is moderated by marine breezes from the San Pablo Bay. The main grape varieties here are Cabernet Sauvignon, Merlot, Chardonnay, Syrah and Pinot Noir.
