Concannon Vineyard is one of California’s oldest and most historic wineries, founded in 1883 by Irish immigrant James Concannon in the Livermore Valley. As a pioneering family in the California wine industry, Concannon introduced many innovations, including being among the first to bottle Petite Sirah as a varietal and playing a key role in the development of California Cabernet Sauvignon through its renowned Concannon Clones.
The estate is known for its beautiful grounds, historic tasting room, and a legacy of four generations of family stewardship. Concannon Vineyard is celebrated for its Cabernet Sauvignon and Petite Sirah, and it continues to be a leader in sustainable winegrowing and hospitality, offering visitors a blend of tradition, innovation, and a welcoming atmosphere in the heart of Livermore wine country.
