Diamond Mountain District
Napa Valley
A small mountain AVA on the western Mayacamas range, known for Cabernet Sauvignon of intensity and structure. The thin volcanic soils and steep terrain force vines to struggle, yielding concentrated wines with a distinctive mineral character.
The wines of Diamond Mountain District are made primarily from Chardonnay, Cabernet Sauvignon, Merlot and other Napa Valley varieties.

Climate
The high elevation and western Mayacamas position creates a cooler, more moderate climate than the valley floor, with significant diurnal temperature variation and protection from afternoon valley heat. Morning fog lingers longer at elevation while afternoon mountain breezes provide natural cooling.
Terroir
The Diamond Mountain District sits on ancient volcanic bedrock from the Mayacamas range, primarily composed of Sonoma Volcanics formation with basaltic and andesitic rocks. The thin, well-draining volcanic soils overlay fractured bedrock that forces vine roots deep into crevices, while the rocky substrate and iron-rich red clay provide excellent drainage and stress the vines through limited water retention.
