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.
The Merlot grape is such a deep blue that it is named for the blackbird. It’s an early ripening grape and one of the primary varietals used In Bordeaux. Merlot is also grown in the "International style," which is harvested later to bring out more tannins and body.
