Langtry Farm Vineyards (Tephra Ridge & Napa Basin) Within our 22,000 acres, lies the world famous Guenoc Valley American Viticultural Area (AVA) and the Tephra Ridge Vineyards. The Guenoc Valley AVA has the distinction of being the first single-proprietor AVA in the country. Langtry Farms is also home to Napa Valley AVA vineyards on the eastern boundary of the property adjacent to Putah Creek known as the Napa Basin Vineyards.

Winery (Langtry Estate & Vineyards) Langtry’s history as a winery dates back to 1854 when wine grapes were first planted in the Guenoc Valley. Victorian actress Lillie Langtry, a colorful theater star in Europe and America owned the property from 1888 to 1906 and produced wine which she claimed would be the “greatest claret in the country.”
