Gemstone has been crafting estate wines from our 16-acre vineyard in Yountville for over twenty-five years. With accolades including a Critics Choice Award from Wine Spectator, Gemstone continues to optimize its vineyard’s unique and diverse soils. Today, Thomas River Brown, winemaker, a Winemaker of the Year recipient, and Amy Marks Dornbusch, Proprietor, continue to carry out Gemstone’s rich history by delivering three stylistically unique expressions of Estate Cabernet Sauvignon. Prices vary; 15% of the purchase price of the products identified on the webpage below will go to Cure Alzheimer’s Fund for research.
