The state in the northwest of the USA with the capital Boise was settled by white people relatively late around 1860 and became the 43rd member of the federation in 1890. In the west, the two important wine-growing states of Washington and Oregon border on it. This cannot be said of Idaho, the first vineyards in the mountainous country (also a ski area) were not planted until the 1970s. They are mainly located east of the capital Boise (City of Trees) in the Sunny Slope area. The climate is characterized by hot days and cool nights, the winters by hard frosts. In 2007, the Snake River Valley was classified as the first and so far only AVA area. Of the approximately 20 producers, Sainte-Chapelle Vineyards dominates the Snake River Valley, where wines and sparkling wines from the Chardonnay, Riesling and Cabernet Sauvignon varieties are produced.
