Diamond Creek produces Cabernet Sauvignon from Calistoga, the northernmost appellation of Napa Valley, where volcanic soils and warm days shape wines of structure and depth. The winery's portfolio centers on single-vineyard and blended expressions: the Three Vineyard Blend Cabernet Sauvignon, Red Rock Terrace Cabernet Sauvignon 40th Anniversary, and Volcanic Hill Cabernet Sauvignon. These wines have been assessed by Wine Enthusiast, Wine Advocate, and Decanter. Calistoga's terroir—marked by mineral-rich earth and intense sun exposure—yields Cabernet with the region's characteristic power and aging potential. Diamond Creek's focus on varietal purity and site-specific character reflects the broader philosophy of Napa's premium producers.
