Located on the western slope of the Mayacamas Mountains, the Moon Mountain District is as rugged as its name suggests. Located on land 400-2000 feet above sea level, all of the vineyards are on hillsides and they border some of Napa Valley's highest elevation mountain vineyards on Moon Mountain's eastern border. This 100% Cabernet Sauvignon from small-production estate Gail Wines was fermented using only native yeast and saw 18 months sur lie aging in neutral oak barrels. Only 600 bottles were made.
