Coonawarra wine region
The Coonawarra wine region is a wine region centred on the town of Coonawarra in the Limestone Coast zone of South Australia. It is known for the Cabernet Sauvignon wines produced on its "terra rossa" soil. The name has been said to have originated in Bindjali, an Aboriginal language, meaning "wild honeysuckle". It is about south-east of Adelaide, close to the border with Victoria.
History
The Aboriginal Australians living in the area when Europeans arrived were the Bindjali people, The word coonawarra is reported to have been their word for honeysuckle, although this meaning has also been ascribed to Penola by the same source.The first vines were planted by John Riddoch at Yallum, South Australia in 1890. Only the Redman family of Rouge Homme continued to produce table wine during this period, during which Shiraz was the main grape variety grown.
Fortunes changed when Samuel Wynn recognised the potential of the strip of terra rossa soil, and bought the original Riddoch cellars in 1951. Led by Wynns and Penfolds, Coonawarra was to play a leading role in the transformation of the Australian wine industry as it changed from making fortified wines to conventional table wines.
Geology
Coonawarra's terra rossa soil is one of the notable terroirs of the New World, covering an area of just 15 km x 2 km north of Penola. It lies on a shallow limestone ridge, raising it above the swampy land either side – it is no coincidence that the Riddoch Highway follows this ridge as carters sought the firmest ground in times past. This special bright red soil is clearly visible on an .To the west of the ridge lies black rendzina soil which is poorly drained, and so is much less favourable for vines. There is also a 'transitional', or brown rendzina, soil which grows vines quite successfully. This geological complexity led to many disputes during an eight-year period before Coonawarra was entered on the Register of Protected Names. At least one vineyard has the boundary pass through the middle.
