The Umpqua Valley AVA contains the drainage basin of the Umpqua River, excluding mountainous regions. The Umpqua Valley has a warmer climate than the Willamette Valley, but is cooler than the Rogue Valley to the south. It is the oldest post-prohibition wine region in Oregon. Grapes grown here include Tempranillo, Baco noir, Pinot noir, Pinot gris, Cabernet Sauvignon, Chardonnay, and Riesling, Grüner Veltliner, and a host of lesser known Vitis vinifera. The region includes two sub-AVAs, the Red Hill Douglas County, Oregon AVA, a single vineyard AVA, as well as the Elkton Oregon AVA, which was established in early 2013.
