Constant Winery
constant_logo.jpg CONSTANT Diamond Mountain Vineyard® may 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.
