Co-founded by Dan and Margaret Duckhorn in 1976, Duckhorn Vineyards has spent forty years establishing itself as one of North America’s premier producers of Napa Valley wines. From its modest inaugural vintage of 800 cases of Cabernet Sauvignon and 800 cases of Merlot in 1978, to its addition of Sauvignon Blanc in 1982, Duckhorn Vineyards has crafted a tradition of quality and excellence that continues today.
