Pine Mountain-Cloverdale Peak is an American Viticultural Area (AVA) straddling the borders of Mendocino and Sonoma County, California.
It was established on October 27, 2011 by the Alcohol and Tobacco Tax and Trade Bureau (TTB), Treasury after reviewing the petition submitted by Sara Schorske of Compliance Service of America on her and on behalf of local wine industry members proposing the 4,570 acres (7 sq mi) northern California viticultural area known as "Pine Mountain-Mayacmas."
The area lies approximately 90 miles (145 km) north of San Francisco and five miles (8 km) north-northeast of Cloverdale, surrounding much of Pine Mountain, which rises to the east of Hwy 101 and the Russian River, to the north of that river's Big Sulphur Creek tributary, and to the immediate west of the Mayacmas Mountains.
It is located at the top of Pine Mountain, at the Northern end of the Mayacamas Range, which separates the Napa and Sonoma growing regions.
This unique microclimate creates an altered growing season for Pine Mountain growers, with bud break occurring two to three weeks after vineyards on the valley floor.
