Sterling Vineyards Platinum Cabernet Sauvignon is the winery's premium expression of Napa Valley craftsmanship, sourced from select sites across the valley floor and mountainside vineyards. This Costco offering is a 6-bottle case of 750ML bottles, making it an excellent value for a reserve-tier Napa Cabernet.

The wine is a full-bodied Cabernet Sauvignon blended with small portions of complementary varietals including Malbec and Petit Verdot. It is aged approximately 20 months in a combination of French, Hungarian, and American oak barrels, imparting layers of complexity and a polished, integrated structure. Alcohol content is approximately 14.9%.

Expect aromas and flavors of Bing cherry, cassis, and mocha, complemented by vanilla and caramel toffee notes from oak aging. The palate shows rich texture with polished tannins and a lingering finish accented by white pepper spice. The wine's structure and concentration give it excellent aging potential, though it is approachable upon release.
