Idaho, with its Snake River Appellation, is on the verge of joining Oregon and Washington as a premier northwestern grape growing state. Although vineyards were first planted in Idaho in the late 1800s, post-prohibition winemaking did not return to Idaho until the 1970s. The vast majority of Idaho’s wineries and vineyards are located in the Snake River Valley near Nampa and Boise at altitudes between 2000 and 3400 feet. Scroll down to find Idaho’s best wineries.
