🍷 Concannon Vineyard

Concannon Vineyard is a historic winery located in Livermore Valley, California, and one of the oldest continuously operating wineries in the state. Founded in 1883 by Irish immigrant James Concannon, the winery helped pioneer the production of Bordeaux varietals in California through the direct importation of vine cuttings from renowned French estates, including Château Margaux and Château d'Yquem. Concannon is recognized as the first winery to commercially bottle Petite Sirah as a varietal wine in 1961, helping establish the grape's identity in the United States.
