South Australia

South Australia is an Australian Geographical Indication (AGI - similar to the European Designation of Origin system) of wine production that covers the entire state of South Australia, Australia.

The indication covers eight wine zones broken down into 19 wine regions, with all but the Far North Wine Zone concentrated in the south east of the state:

Adelaide Super Wine Zone.
Barossa Wine Zone - including the Barossa Valley and Eden Valley Wine Regions.
Far North Wine Zone - including the Southern Flinders Ranges Wine Region.
Fleurieu Wine Zone - including the Currency Creek, Kangaroo Island, Langhorne Creek, McLaren Vale and Southern Fleurieu Wine Regions.
Limestone Coast Wine Zone - including the Coonawarra, Mount Benson, Mount Gambier, Padthaway, Robe and Wrattonbully Wine Regions.
Lower Murray Wine Zone - including the Riverland Wine Region.
Mount Lofty Ranges Wine Zone - including the Adelaide Hills, Adelaide Plains and Clare Valley Wine Regions.
Peninsulas Wine Zone - including the Southern Eyre Peninsula Wine Region.

Within the zones and even within the regions, there is variation in varieties and wine styles, dependent on latitude, orientation, soil, rainfall (or irrigation), and other site-specific aspects. Many of South Australia's wine regions vie for international attention as quality sources of a particular variety; but equally, some of Australia's most famous and highly awarded wines are multi-regional blends.
