Part III: Fort Ross-Seaview AVA Today
Fort Ross-Seaview consists of 27,500 acres contained entirely within the large Sonoma Coast AVA and does
not overlap any other viticultural area. The formal petition calling for AVA approval was presented in 2003 by
Patrick Shabram, a consulting geographer and David Hirsch of Hirsch Vineyards, but not approved until
January 2012. This was due to various opinions on boundaries, whether to include Annapolis to the North, and
what the new AVA would be called. Hirsch notes that 18 different growers were involved in penning the
The distinguishing feature of the Fort Ross-Seaview AVA is that most vineyards are located along the Pacific
coastline on ridge tops at elevations between 920 and 1,800 feet. This puts them above the natural fog line,
but close to the Pacific Ocean, creating a moderate climate of “cool sunshine.” Unlike most of California where
vineyards are planted on valley floors and some hillsides in alluvial soils, vineyards in the Fort Ross-Seaview
AVA are on hilltops flanked by gullies and narrow valleys and amongst dense redwood forests. The San
Andreas Fault runs right through the region and created the convoluted topography. There are many soil
types, but sedimentary rock, sandstone and shale prevail.
David Hirsch pointed out that the Fort Ross-Seaview area, at least where he is located, is a confluence of four
ecosystems, making the region particularly unique: the ocean, the rivers, the redwood forest and the ridge
tops. The nearby Pacific Ocean helps to keep the vineyard temperatures from rising or falling to extremes.
The rivers in the gullies play a complimentary role, helping to cool the ridge tops in the heat as well as drawing
cool air downward in the cold to negate the threat of frost. The redwood forests are essentially a rainforest,
while the ridge tops have a continental climate. When weather systems arrive from the Southeast, vineyards
above 900 feet elevation have longer periods of sunlight and more warmth than the land below with the
temperature reaching into the 90s, and even into triple digits on occasion.
Pinot Noir and Chardonnay are the most common varieties grown in the Fort Ross-Seaview AVA with small
amounts of Zinfandel, Petite Sirah, Syrah, Pinotage, Viognier, Marsanne and Roussane. There are 18
commercial vineyards on 506 acres.
