Limestone Coast zone (wine)

Limestone Coast zone is a wine zone located in the south east of South Australia. It extends south of a line of latitude approximately in line with Cape Willoughby at the east end of Kangaroo Island and it is bounded by the continental coastline and the border with Victoria. It consists of the following wine regions all of which have received appellation as an Australian Geographical Indication (AGI): Coonawarra, Mount Benson, Mount Gambier, Robe, Padthaway, Wrattonbully and a small number of vineyards located outside the above regions. The zone received AGI in 1996.
Extent and appellation.
The Limestone Coast zone is located in the south-east of South Australia bounded by the continental coastline to the south, the border with the neighbouring state of Victoria to the east and the Lower Murray wine zone to the north. The wine zone is the land south of a line located at appropriately 36 degrees 50 minutes south, i.e. in line with Cape Willoughby at the east end of Kangaroo Island. The term ‘Limestone Coast’ was registered as an AGI under the "Wine Australia Corporation Act 1980" on 27 December 1996.
