Sinegal Estate Reserve Cabernet Sauvignon is a premium red wine from Napa Valley's prestigious St. Helena appellation, produced by the 30-acre estate founded by Jim and David Sinegal — co-founders of Costco — in 2013. The estate features vines over 20 years old and focuses on crafting benchmark Napa Valley Cabernet Sauvignon from both estate-grown fruit and select vineyard sources throughout the valley.

The Reserve designation represents the estate's most opulent expression, aged in premium French oak barrels to deliver a wine of exceptional depth and complexity. Aromas of blue and black fruit — blackcurrant, blackberry, and dark cherry — are complemented by notes of dark chocolate, cedar, smoke, leather, and baking spice. On the palate, the wine opens with a velvety texture before revealing layers of flavor, firm but polished tannins, and a beautifully balanced finish. Vinous has awarded the Reserve 94 points, and Wine Advocate has scored it 94–96, praising its "terrific intensity and richness."

This 750ml bottle is sold individually and is ideally suited for cellaring or special occasions, representing outstanding Napa Valley Cabernet Sauvignon value at the Costco price point.
