About Napa Basin

The Napa Basin Vineyard is located within the Napa Valley AVA and within proximity to the eastern boundary of Langtry Farms. The vineyard is 180 acres and planted to cabernet sauvignon, petite sirah, petit verdot, merlot, malbec, and cabernet franc. The Napa Basin Vineyard produces exceptionally high quality fruit as a result of its well-drained red volcanic soils and its cool nights and warm days. Diurnal temperature ranges can reach 50 degrees in a twenty four hour period. The Napa Basin Vineyard rests at an elevation of 650 feet on a prominent bend in Putah Creek.
