At 72,000 hectares, South Australia is the engine room of the country's wine industry, responsible for 43 percent of its vineyards and encompassing some of Australia’s most famous fine wine regions.
One of the most important areas in qualitative terms is the Barossa Valley, beginning 50km north-east of Adelaide, and famous for its full-bodied Shiraz, as well as for its Grenache and Mourvèdre. To the east, the cool Eden Valley is home to some really fine Riesling and top-class Shiraz, such as that made by Henschke. To the north of Barossa is the Clare Valley, also a source of good Riesling but home to well-structured reds as well.
South-east of Adelaide lies the delightful vineyard area of the Adelaide Hills, where fine Sauvignon, Chardonnay, Riesling and Pinot Noir are produced by wineries such as Petaluma and Llangibby Estate. Langhorne Creek to the east of Adelaide has earned a reputation for its Cabernet Sauvignon, Verdelho and Shiraz while, between Adelaide and the sea, McLaren Vale is a noted area for red wines.
The unique vineyard region of Coonawarra lies 400km south-east in an area of pure limestone topped by a loose, red topsoil. Cool enough to resemble Bordeaux, this area produces great Cabernets and Merlots and is much in demand. Slightly to the north and to the west lie the regions of Padthaway and Mount Benson respectively, which enjoy similar success as sources of great white wines, especially Chardonnay. Wrattonbully however is known for its fresh, varietally-pure Cabernet Sauvignon and Merlot.
However it’s the less-distinguished Riverland region that accounts for 50 percent of the state’s wine production.
