150 vineyard acres (out of 16,000 in the AVA!)
Became an AVA in 2002
Spreading west of Lake Sonoma to the Mendocino County border, Rockpile is known for intensely-flavored red grape varietals with great concentration and balance. At elevations up to 1,900 feet, Rockpile is too far upland for the penetrating fogs that influence other Sonoma appellations. This exposes grapes to more California warmth and sunshine, boosting their ripeness and richness. The appellation is designated by altitude and geography. More Info.
