The South Australian wine industry is responsible for more than half the production of all Australian wine. South Australia has a vast diversity in geography and climate which allows the state to be able to produce a range of grape varieties–from the cool climate Riesling variety in the Clare Valley wine region to the big, full bodied Shiraz wines of the Barossa Valley.
Some of Australia's best-known wines like Penfolds Grange, Jacob's Creek, Yalumba and Henschke Hill of Grace are produced there, as well as many of Australia's mass-produced box wines.[1]
As with most agriculture in Australia, irrigation is vital to the success of the South Australian wine industry.
