South Australia is a massive state in the South Central portion of the Australian continent. It accounts for fully one-half of all Australian production, and produces everything from vast volumes of supermarket wines from the arid interior of the Riverlands to most of Australia's most-coveted reds in the famous regions surrounding Adelaide and the Barossa Valley.

Wines labeled simply South Australia are often high volume blends from throughout the region, though exceptions exist, none more prominently than the penchant for Penfolds of labeling some of their most iconic reds with a simple South Australia designation. Don't be fooled. For in depth information on specific South Australian appellations consult the other regions. (Wine/Appellations)
