Geographic Indications – Australia's Appellation (AOC) system

Geographic Indication (GI) is the term for the officially recognised super zones, zones, regions and subregions of Australia which have been entered in the Register of Protected Names pursuant to the Australian Wine and Brandy Corporation Act 1980 (Cth). At its most general, registration is based on state boundaries or an aggregation of states or parts thereof. The broadest is South Eastern Australia, which takes in the whole of New South Wales, Victoria and Tasmania and those sectors of Queensland and South Australia in which grapes are (or may conceivably be in the future) grown. Next come individual states, designations which need no explanation. Each state is then divided into zones; securing agreement on the names and boundaries of the zones was completed in 1996. The regulations provide that a zone is simply an area of land, without any particular qualifying attributes. The one super zone is Adelaide, which includes the Mount Lofty Ranges, Fleurieu and Barossa zones.

Each zone can then be subdivided into regions (the vast majority are), and eachregion into subregions (of which there are only a few). A region must be a single parcel (or piece) of land, comprising at least five independently owned wine grape vineyards of at least 5ha each, and usually producing a total of at least 500 tonnes of wine grapes a year. A region is required to be measurably different from adjoining regions, and have measurable homogeneity in grapegrowing attributes over its area. A subregion must also be a single parcel of land, comprising at least five independently owned wine grape vineyards of at least 5ha each, and usually producing at least 500 tonnes of wine grapes annually. However, a subregion is required to be substantially different from other parts of the region, and have substantial homogeneity in grapegrowing attributes over the area. As is obvious, the legislation is vague, and the difference between a region and a subregion is extremely subtle.
