Limestone Coast G.I.

Coonawarra and Wrattonbully are part of the greater Limestone Coast Region Geographical Indication (GI).

This is an area of unique characteristics which are a result of the entire region being submerged under the sea for over 25 million years, during which time marine crustaceans and shells on the sea floor formed limestone reefs. Approximately one million years ago the region began rising out of the sea and during periods of glaciation over time the sea receded. In its wake, it left fourteen stranded coastlines or ranges between the Naracoorte range and the current coastline. Wind-blown organic material accumulated on top of these limestone reefs and formed the famous terra rossa soils found particularly in the Coonawarra and Wrattonbully wine regions.
