The 27,500-acre Fort Ross-Seaview American viticultural area is located in the western part of Sonoma County, California contains 18 commercial vineyards on 506 acres, lies close to the Pacific Ocean and is about 65 miles north-northwest of San Francisco. It lies entirely within the Sonoma Coast viticultural area and does not overlap, or otherwise affect, any other viticultural areas.

Vineyards within this area are generally located on rounded ridges with summits extending above 1,200 feet consisting of steep, mountainous terrain made up of canyons, narrow valleys, ridges, and 800- to 1,800-foot peaks. Areas above 900 feet in elevation, the climate is influenced by longer periods of sunlight and is warmer than that in the surrounding land below.
