Diamond Mountain is located at the northwestern side of Napa Valley, near Calistoga. Earth-friendly practices are used to prevent rain erosion on the terraced hillsides. Partial barrel fermentations, in-barrel malolactic fermentation and new French oak all contribute to this wine’s complexity. The bold, ripe flavors complement full-bodied entrées, especially grilled steak with small red potatoes drizzled with sage butter.

Our 2015 Diamond Mountain Cabernet Sauvignon expresses the bold, mountain-grown fruit of its provenance—a vineyard on Diamond Mountain, which is part of the Mayacamas Range that flanks Napa Valley on the west side. Terroir nuances of forest loam, slate, graphite, as well as dried herbs like mountain sage, anise seed, and wild violet layer the intense macerated blackberry, dark plum, blueberry, black cherry and mocha aromas. Supported by sweet baking spice notes from the oak barrel integration, you’ll find allspice, vanilla bean, cardamom and charred toast notes coming from new French oak barrels. From the full, rich and silky entry on the palate to the persistent, dark-fruit lengthy finish, the wine is beautifully balanced and well structured. Muscular, yet fine-grained tannins support the wine and promise cellar worthiness. Consider decanting this wine if you choose to enjoy it in its youth.
The beautiful, forested Diamond Mountain District, designated an American Viticultural Area in 2001, rises 2,200 feet above northern Napa Valley. We select the grapes for our Diamond Mountain Cabernet Sauvignon from vines in blocks 3C and 6A of our estate vineyard, which is known as Peterson Vineyard. Block 3C is budded to Cabernet Sauvignon clone 169, while Block 6A is clone 4. The vineyard site’s deep, well-draining Aiken loam soils—iron-rich and acidic—are formed from weathered basic volcanic rock. Cool breezes coming through the Sonoma Gap give the grapes their excellent sugar-to-acid balance and long hang time.
