The Suisun Valley AVA is an American Viticultural Area in Solano County, California, located just east of the Napa Valley wine region in the Coast Range. It was established as a wine appellation on 27 December 1982, making it among the first AVAs of California (eighteenth overall), Napa Valley being the first.
Suisun Valley is a region in the California Coast Ranges that is bordered on the east side by the Blue Ridge of the Vaca Mountains, and on the west side by the Howell Mountains, which are also called the St. George Range. The valley is located almost entirely in Solano County with a northern terminus near the county line with Napa County, and a southern terminus at Suisun Bay in the estuary where the Sacramento River enters San Francisco Bay.
Elevations on the valley floor range from 100 to 200 feet (30 to 61 m) above sea level, rising steeply to 1,122 feet (342 m) at Okell Hill on the north side, and to 2,162 feet (659 m) on the west side at Twin Sisters, a twin summit that is the high point of the Howell Mountains, as well as a prominent landmark in the valley. Blue Ridge on the east side of the valley exceeds 2,000 feet (610 m) elevation for much of its length.
The valley is approximately 3 miles (5 km) by 8 miles (13 km), and contains about 15,000 acres (61 km2). More than 3,000 acres (12 km2) of the valley is currently planted as vineyard, with more than twenty varieties of wine grapes represented, including Barbera, Cabernet Sauvignon, Chardonnay, French Colombard, Gamay (Valdiguie), Grenache, Merlot, Mouvedre, Muscat Canelli, Petite Sirah, Petite Verdot, Pinot Gris, Pinot Noir, Primitivo, Rousanne, Sauvignon Blanc, Sangiovese, Shiraz, Syrah, Viognier, Riesling, and Zinfandel.
