The Snake River Valley in southwestern Idaho and a small eastern portion of Oregon, has the highest density of vineyards and wineries in the state, becoming Idaho’s first American Viticultural Area (AVA) in 2007. Spanning 8,000 square miles of land which was once the prehistoric bed of Lake Idaho; the Snake River Valley, containing the sub-wine region, Eagle Foothills AVA, is now home to a young and unpretentious wine tasting scene. Local vintners and newly transplanted winemakers alike are part of the up-and-coming wine region, which has earned a dazzling reputation from Boise and surrounding area wine enthusiasts.
Worth mentioning is a unique hotbed of boutique wineries, collectively known as the Sunnyslope Wine Trail. This nonprofit alliance located in and around Caldwell is made up of 15 area wineries and is definitely worth a visit. All proceeds from the Sunnyslope Wine Trail are used to fund various agricultural ventures in the Caldwell area and to help drive wine tourism to the various local wineries.
