The Coonawarra wine region is a wine region centred on the town of Coonawarra in the Limestone Coast zone of South Australia. If you enjoy rich, colourful wines, you’ll love the Coonawarra. Its Cabernet Sauvignon is internationally renowned and its Shiraz isn’t far behind. The region’s Terra Rossa soil (red soil containing limestone) is perfect for grape growing. Coonawarra is a small region, only 20 kilometres in length and two kilometres in diameter. Despite this, it is home to more than 24 cellar doors. They’re close together and well signposted, so you’ll find them easily.
