The 38,000 acre Fountaingrove District AVA was created on February 18, 2015. The AVA is located in Sonoma County and is bordered to the north by Chalk Hill and Knights Valley, to the south by the Sonoma Valley, to the west by the Russian River Valley, and to the east by Napa’s Diamond Mountain District and Spring Mountain District. The Fountaingrove region is relatively inland compared to most Sonoma AVA’s, but maritime breezes and fog entering through the gap in the Sonoma Mountains east of Santa Rosa moderate the climate. The terrain is mainly rolling hills with Sonoma Volcanic and Franciscan Formation bedrock soils.
