 It is entirely contained within the larger Southern Oregon AVA and includes the drainage basin of the Rogue River and several tributaries, including the Illinois River, the Applegate River, and Bear Creek.Most wineries in the region are found in the valleys formed by one of these three tributaries, rather than along the Rogue River itself.The region is wide by long (most of the land within the AVA capable of producing high quality wine is not currently used for grape cultivation); there are fewer than 20 wineries with only planted.
