CONSTANT Diamond Mountain Vineyard® may just be the highest (2121’), oldest (1895) vineyard, and smallest winery in the Napa Valley. Our location here at the top of the Diamond Mountain District appellation is, perhaps, one of the best places in the world to grow Bordeaux varietals and is unequivocally, the most beautiful and romantic.CONSTANT produces a limited supply of Cabernet Sauvignon, Cabernet Franc, Claret and Syrah from its mountain estate exclusively for mailing list members.
