The Willamette Valley AVA sits inside the Willamette Valley in Oregon. It spans from the Columbia River in the north to the southern tip of Eugene and from the Oregon coast on the west to the Cascade Mountains in the east. It is the largest, and most popular, of Oregon’s AVAs: it’s 5,200 square miles (150 miles long and about 60 miles wide) and contains over 200 of Oregon’s 700+ wineries. Willamette contains six sub-AVAs: Chehalem Mountains, Dundee Hills, Eola-Amity Hills, McMinnville, Ribbon Ridge and Yamhill-Carlton.
