Duckhorn Vineyards was founded in 1976 in St. Helena, in the Napa Valley. It was started by Dan and Margaret Duckhorn after Dan, a California native, toured the Bordeaux region of France in the 1970s. In 2007 a private equity firm took a significant ownership interest in Duckhorn, though Dan Duckhorn remains in charge of the estate. The winemaker is Renee Ary. The 229-acre estate is known for its big Cabernet Sauvignons and Merlots. Duckhorn was one of the first California producers to champion Merlot, and its Merlots are still highly regarded although today the estate also makes Sauvignon Blanc, Cabernet France and Semillon. About 75,000 cases are produced annually. Robert M. Parker has written that Duckhorn has “a very positive style that represents a hypothetical blend of the ripeness of Napa allied with the elegance of a top Bordeaux.”
