Diamond Mountain District

The Diamond Mountain District received its AVA designation in 2001. The region sits on 5,000 acres and is a sub-appellation of the Napa Valley AVA. Located in the Mayacamas Mountains, Diamond Mountain's unique feature is its higher elevation than most of the growing regions in Napa Valley. The higher elevation allows the vines to sit above the fog line and receive a few extended hours of direct sunlight daily. The soil is volcanic, porous, and well draining which forces the vines to struggle and put all of their efforts into the fruit. Given the warm sunny days and cool nightly breezes, the area has a significant diurnal temperature variation. The region is known for Cabernet Sauvignon, Merlot, Malbec, Cabernet Franc, Petit Verdot, and Sauvignon Blanc.
