Region Napa Valley
Winemaker Trevor Durling

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.

Appellation: Diamond Mountain

Tasting Notes

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.

Vineyard Notes

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.

Vintage Notes

Although in 2015 we received three-quarters of our normal rainfall, the cumulative effect of four years of drought in Napa Valley resulted in a light crop. Fortunately, the vintage made up for the small quantity by yielding outstanding grape quality. The small clusters and dry, warm conditions promoted an early, condensed harvest that kept us hopping. At Provenance, we began the harvest picking Sauvignon Blanc on August 8 and wrapped up the vintage with Cabernet Sauvignon by October 12. The wines of 2015 are known for their highly concentrated, complex flavors.

Winemaking Notes

We hand sorted the grapes first in the vineyard, as we picked them at dawn, and then again at the winery for optimum quality. We cold soaked the must for gentle extraction and fermented it in a combination of 60-gallon oak barrels (to seamlessly integrate tannins) and stainless steel tanks. Following extended maceration and pressing, the wine completed malolactic fermentation in barrels to round the acidity and enrich the mouthfeel. Gentle rackings naturally clarified the wine, while barrel aging melded complex oak nuances with the ripe, dark-fruit expression.
