PICTURE BREATHTAKING RIVER VALLEYS and rolling hillsides rich with ancient but fertile volcanic soil, the type of soil that results in wines of remarkable character and exceptional quality. There’s only a few places in the U.S. with soil like that, and one of them is Idaho.

Understandably, wine grapes probably aren’t your first thought when thinking about a state known for growing potatoes. However, in addition to lush, volcanic sediment that’s chock-full of minerals, Idaho enjoys temperate weather, abundant sunshine and plentiful water―all things perfect for vinifera. These high-desert vineyards off the beaten wine path are ideally situated, with cold winter dormancy and a long, warm growing season. The extreme diurnal temperatures (meaning warm days and cool nights) result in balanced wines that taste of the fruit they’re made from, while still retaining structure, sugars and acid. And maybe due in part to a Wild West attitude (cue tumbleweeds and the theme song to Clint Eastwood’s The Good, the Bad, and the Ugly), Idaho winemakers are still relatively unrestrained by convention, which allows them the freedom to experiment and define the unique styles of the region’s wines as expressions of the terroir.

Though the first Pacific Northwest vineyards were planted in the Clearwater Valley of Northern Idaho in 1864—when it was still the Old West and well before Prohibition took root— the state’s wine industry was slow to return after Prohibition. Oregon and Washington finally welcomed Idaho to the Northwest wine party in 2007, when the Snake River Valley became Idaho’s first American Viticultural Area (AVA). Now poised for significant growth, the state has more than 50 wineries and more than 8,000 acres planted with vinifera in three distinct AVAs (Snake River Valley, Eagle Foothills and Lewis Clark).

Since Idaho is considered something of a Johnny-come-lately on the wine scene, it can be compared to California 40 to 50 years ago, Oregon 30 to 40 years ago, and Washington 20 to 30 years ago. The beauty of being a relatively undiscovered wine destination means it’s still affordable and far less traveled than other more established territories. There’s no better time to experience wines that taste of the mystique and exquisite beauty that stem from the snowcapped mountains and crisp, clean rivers of the Idaho countryside.
