Limestone Coast Zone, moderately cool, high-quality wine area in south australia encompassing Coonawarra, Mount Benson, Mount Gambier, Padthaway, Robe, and Wrattonbully regions. The zone is much greater in extent, with the districts of Bordertown and Penola candidates for official recognition as regions. Bordertown, the furthest north, is the warmest area (robust Shiraz, Cabernet Sauvignon, etc.). Mount Gambier, to the extreme south, is the coolest, best suited to Pinot Noir and Chardonnay.
