Gemstone produces Cabernet Sauvignon and Bordeaux blends from Yountville, the heart of Napa Valley's most prestigious wine country. The region's gravelly soils and moderate climate favor the dark, structured wines that define the appellation. Facets Cabernet Sauvignon, the winery's flagship, demonstrates the intensity and aging potential Yountville terroir can achieve. Heritage Selection Cabernet Sauvignon and Estate Red—a blend of Petit Verdot, Cabernet Sauvignon, and Merlot—round out the core portfolio. All three wines have been assessed by Wine Advocate, Wine Spectator, Wine Enthusiast, and Decanter, the principal critics of fine wine.
