Limestone Coast Zone (Regions: Coonawarra, Mount Benson, Padthaway, Robe, Wrattonbully)
1. Coonawarra
- Most southerly wine district in South Australia
- Only 60 kilometres (37 miles) inland, and a predominantly maritime climate prevails with the dry and moderately cool summers
- Coonawarra climate can resemble that of Bordeaux
- It is the extensive cloud cover that moderates the most important ripening period temperatures and which sets the region apart from other wine regions.
- Known for the world renowned Cabernet Sauvignon grown in its terra rossa soil (Australia’s most famous vividly red colored soil)
- The other soil type: black rendzina soil, lying to the west of the limestone ridge, but because of its poor drainage this soil does not favor the production of quality red wine fruit
- Other varieties: Chardonnay, Malbec, Merlot, Petit Verdot, Pinot noir, Riesling, Sauvignon blanc, Semillon and Shiraz
2. Mount Benson
- Merlot, Shiraz, Cabernet Sauvignon, Pinot Gris and Sauvignon Blanc
- Located on the Western edge of the Limestone Coast of South Australia’s South Eastern strip
- Varieties: Merlot, Shiraz, Cabernet Sauvignon, Viognier, Pinot Gris and Sauvignon Blanc
- Climate is cool and maritime
- Water-holding mineral base under rich red terra rossa soils, perfect for viticulture
- Wines made here tend to be fruitier and less tannic than Coonawarra
3. Padthaway
- Originally known as Keppoch
- Slightly warmer than Coonawarra
- No significant mountains, generally a maritime climate
- Most of the vineyards are on flat ground except on the region’s eastern boundary where vines grow on the gently undulating wooded slopes of the West Naracoorte Ridge

- Other varieties: Riesling, Sauvignon Blanc and Verdelho and their reds Shiraz, Cabernet Sauvignon and Malbec.
4. Robe
- Located near Mount Benson in the southeast part of the state
- The region extends east along the Limestone Coast from Robe to Beachport in the east
- Newest official wine region, having been declared in 2006
- The climate, like Mt Benson’s, is cool and strongly maritime, being influenced by the Southern Ocean to the west and lakes to the east

- Climate is slightly warmer than Coonawarra and cooler than Padthaway
- Cabernet Sauvignon is the main variety grown with just under half the total area
