Sterling Vineyards

Our Diamond Mountain Ranch lies west of the town of Calistoga, near the top of the Diamond Mountain American Viticultural Area (AVA). The ranch’s 120 acres, planted with Cabernet Sauvignon, Malbec, Petit Verdot, and Cabernet Franc, range in elevation from 1,700 to 2,000 feet, climbing the steep northern face of the Mayacamas Mountains. Nearly vertical slopes, austere soils, and dry farming stress the vines planted here, and low-vigor volcanic soils provide minimal nutrition. This results in small, intensely concentrated fruit clusters that make deeply pigmented, assertive wines with full body and rich tannins.
