Our 2015 Armstrong Ranch 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. Armstrong Ranch sits high atop Diamond Mountain, just west of Calistoga.

Varietal Composition: 100% Cabernet Sauvignon
Aging: 20 months, 100% French Oak (82% New)
Production: 270 cases
Terroir nuances of forest floor, cocoa powder, as well as dried herbs like mountain sage, rosemary and cigar tobacco layer the dark blackberry, dark plum, blueberry, black raspberry, cola and bittersweet chocolate aromas. Supported by sweet baking spice notes from the oak barrel integration, you’ll find cedar, cinnamon, allspice, vanilla bean, clove and charred toast notes coming from new French oak barrels. From the layered and nuanced entry on the palate to the persistent, dark-fruit and espresso-like lengthy finish, the wine is complex and well-structured while being framed with minerality. Mouth filling well integrated tannins support the texture and structure. Consider decanting this wine if you choose to enjoy it in its youth. Only 270 cases were produced and they are available exclusively at our winery.
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.
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 in 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.
