The Southern Oregon AVA, is an American Viticultural Area which lies in Southern Oregon, United States. The Southern Oregon AVA was established in 2004, and was created to include the land of two smaller AVAs, the Rogue Valley AVA and the Umpqua Valley AVA. Southern Oregon AVA was established to allow the two principal winegrowing regions in the southern part of the state to market themselves jointly. This creation of a "super-AVA" is a departure from the trend in the Willamette Valley AVA or northern Oregon of establishing smaller AVAs specific to a particular locale's climate or soil conditions.
