Diamond Mountain District
Location: California, United States
Legal name: Diamond Mountain District
Region: Napa Valley

Diamond Mountain District sits in the northern Mayacamas above the Napa Valley floor near Calistoga. Cabernet Sauvignon dominates the AVA's identity, with wines that often feel powerful, dark-fruited, and mineral, supported by pronounced tannins. It is a useful label cue for drinkers who want Napa Cabernet from a small mountain district rather than a warmer valley-floor site.
