Duckhorn Vineyards has established itself over a number of decades as one of Napa Valley's most prestigious wineries. Unlike most Napa wineries, it is most famous for its Merlot, which founders Dan and Margaret Duckhorn saw as more than just a blending variety. Duckhorn makes a wide range of wines, from varietal and blended wines focusing on Merlot to wines made from other classic California varieties like Cabernet Sauvignon, Pinot Noir and Sauvignon Blanc.
