Constant Diamond Mountain Vineyard


CONSTANT Diamond Mountain Vineyard® may just be the highest (2121’), oldest (1895) vineyard, and smallest winery in the Napa Valley. Its location 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 Estate Cabernet Sauvignon, Cabernet Franc, Claret and Syrah from its mountain estate exclusively for mailing list members.
