O'Shaughnessy Estate Winery

1150 Friesen Drive
Angwin, CA 94508



Many of our estate vines now exhibit fourteen years of age. They have established deep roots on our 100 acre hillside property. Between 1997 and 2002, we planted 29 acres of Cabernet Sauvignon. We also cultivate 6 acres of blending varietal: Cabernet Franc, Petit Verdot, Merlot, Malbec, Carmenere and St. Macaire. In pursuit of maximizing our options for flavor, we utilized several different root stocks and clones for our Cabernet plantings. The vines span two distinct vineyards which we have the privilege of farming. Amphitheater derives its name from its shape across the hillside. Rancho del Oso, nearest the winery, boasts a resident black bear who visits from time to time. He has no part in either viticulture or winemaking.
