Located about 70 kilometres northeast of Adelaide in the state of South Australia, the GI is one of the most important and famous wine growing areas in Australia. The surrounding Barossa Ranges are part of the South Australian Mount Lofty Ranges. The name Barossa is of Spanish origin. Together with the Eden Valley area, Barossa Valley forms the Barossa Zone. The first settlers were of English descent. The basis for viticulture, however, was created a little later by German settlers, mainly from Silesia, as well as Poznan and Prussia between 1840 and 1880, who brought the Riesling. The frequent German street names are a reminder of this. In 1847, Johann Gramp (1819-1903), an immigrant from Bavaria, planted the first vines on the flat valley floor; today this is the Orlando winery. In 1845, the English doctor Dr. Christopher Penfold (1811-1870) founded his winery here, which still exists under Penfolds today. The famous viticulture pioneer Max Schubert (1915-1994) later worked in this business. Joseph Ernest Seppelt (1813-1868), who came from Silesia, founded one of the largest wineries on the continent in 1851
Soon wine became one of the most important products and around 1890 it was already exported to England. Due to the hot and dry climate, a large amount of artificial irrigation is necessary. The vineyards are mainly on flat land at an altitude of between 240 and 300 metres above sea level. The area supplies a large part of the Australian production, but grapes from other areas are also processed. The vineyards cover about 10,000 hectares, the most important grape varieties are Riesling, Shiraz(Syrah) and Cabernet Sauvignon. Well-known producers are Glaetzer, Henschke, Krondorf, Charles Melton, Mitolo, Orlando, Penfolds, Peter Lehmann, Richmond Grove, Rockford, Saltram, Seppelt, St. Hallett, Veritas, Wolf Blass(Treasury Wine Estates) and Yalumba.
