Coonawarra

The Coonawarra is a wine region in South Australia's Limestone Coast, well-known for its red wines. The region is identified by a strip of terra rossa soil (rich red topsoil over porous limestone) approximately 15 km long, and only 2 km wide along the Riddoch Highway just north of Penola. The official region boundaries have been subject to a number of disputes between vignerons and winemakers with grapes on the terra rossa, and other vines growing nearby. At least one vineyard (belonging to Penola High School) has the boundary pass through the middle.

Wine production started in 1890 in Coonawarra as a byproduct of the Coonawarra Fruit Colony formed by John Riddoch.
