In 1982, Sir Peter and Lady Michael purchased 630 acres of volcanic ridges on the western face of Mount St. Helena in the Knights Valley AVA of Sonoma County. Drawing inspiration from the great wineries of Burgundy and Bordeaux, the family hired like-minded viticulturists and winemakers to help them create terroir-driven, estate Sauvignon Blanc, Chardonnay, Pinot Noir, and Cabernet Sauvignon blends that would stand the test of time. Today, second-generation Paul Michael and his wife Emily, oversee the winery adhering to the founding principles of mountain vineyards, classical winemaking, and limited production. With a commitment to sustainability, each estate carries the Fish Friendly Farming, Sonoma Certified Sustainable, and California Sustainable Winery & Vineyards certifications.
