This is the "mothership" appellation of Washington wine country, with eight of the state’s eleven appellations tucked into the expansive borders of the Columbia Valley AVA. The Columbia Valley begins at the Oregon border and stretches in a loose triangular shape to the Idaho border, before moving north towards Lake Chelan. The celebrity grapes of the Columbia Valley are Merlot, Syrah and Cabernet Sauvignon for reds and Riesling and Chardonnay for the white wines.
