All Jarvis wines are produced from estate vineyards, located high above the city of Napa, in the beautifully rugged mountains between Mt. George and Milliken Canyon at the southeastern end of the Napa Valley. The vineyards are planted in gently sloping meadows one thousand feet above the valley floor. As the cool maritime air passes over the Carneros flats and begins flowing into the valley, it falls about seven degrees in temperature for the thousand feet of vertical rise. As such, our vineyards tend to be cooler by several degrees than the famous Carneros region! These cooler temperatures allow a long “hang time,” which permits a long, slow fruit maturation for maximum flavor and concentration at harvest.
