The Duncan Family of Silver Oak established Twomey in 1999 to pursue the discovery of varietals in California beyond Cabernet Sauvignon. Twomey uses the same philosophy that has guided Silver Oak since its founding in 1972: make exceptional, food-friendly wines that are deliciously drinkable upon release. At Twomey, they apply their 40 years of winemaking experience combined with a spirit of innovation to create their Single Vineyard Napa Valley Merlot, four Appellation and Single Vineyard Pinot Noirs and Estate Sauvignon Blanc. With a focus on excellence and sustainability, Twomey sources fruit from some of the best appellations and vineyard sites in California. At their wineries in Calistoga and Healdsburg, they work small to create unique, approachable wines that you will enjoy with friends and family.
