Hells Canyon vineyards were planted in 1981 on the sunny slope above the banks of the Snake River, overlooking the Owyhee Mountains. It is the oldest wine grape vineyard in Idaho, and is made up of Chardonnay, Cabernet Sauvignon, Merlot, Cabernet Franc and Syrah varietals. The elevation at the site is 2,700 feet. The protected Treasure Valley is also influenced by marine air flowing from the Pacific along the Columbia and Snake rivers which moderates the mountain climate enough for grapes. Ancient volcanic soils contribute to good drainage and trace elements also allow for deep root penetration. The big Idaho sky is full of sun which means ripe fruity flavors. Natural acid balance is achieved during the cool ripening month of September when temperature differences between daytime and nighttime elevate sugar levels while maintaining the natural acids.
