Approved in April 2007, the Snake River Valley was Idaho's first designated American Viticultural Area (AVA). The AVA is located in Southwestern Idaho and features the largest density of vineyards and wineries in the state. The area encompasses more than 8,000 square miles at latitudes comparable to many famous wine regions around the world (43°- 46°). Formed more than four million years ago, the Snake River Valley overlays the ancient Lake Idaho bed, which creates its natural boundaries. The result is a distinctive grape growing region whose ancient volcanic sediment have bestowed fertile, well-draining soils that give growers better control throughout the grape-growing process. More importantly, this soil contributes to a unique terroir that— in the hands of talented winemakers—consistently delivers premium wines that are as memorable as they are delicious.
