Founded by legendary vintners Dan and Margaret Duckhorn in 1976, Duckhorn Vineyards is an iconic Napa Valley winery. Crafted using grapes from Napa Valley’s finest Merlot vineyards, including our own estate properties, this benchmark wine combines both mountain and valley-floor fruit to create an impeccably balanced Merlot with signature flavors of black cherry, plum and spice.
