From the confounding mass that is the Sonoma Coast AVA the admirably focused Fort Ross sub-AVA emerged in 2012. Vineyards are sited on rounded ridges with summits exceeding 1,800 ft, above the fog line yet within the path of Pacific winds that ensure a cool climate. Yet these summits receive longer periods of sunlight and are warmer than the land below, allowing for the maturation of Chardonnay, Pinot Noir, and Syrah grapes with high acidity and lean, angular character—a style gaining increasing acceptance. Hirsch, Flowers, Wild Hog, Fort Ross, and Peay are among the well-known producer-growers; Marcassin, Pahlmeyer, and Peter Michael have vineyards here, too.
