    Shiraz country

    Barossa Valley was entered in Australia's Register of Protected Names on 15 August 1997 and lies within the Barossa zone of South Australia.2 At 30 April 2024 the region had 11,930 hectares of vineyards, of which 7,729 hectares were Shiraz (Syrah).1 The next largest variety was Cabernet Sauvignon.1

    Sand and clay

    Barossa soils range from deep siliceous sands to heavy black cracking clays, with well-drained red and red-brown clays and poorly drained yellow and grey subsoil clays, and are generally of low fertility.3 The Barossa Grape & Wine Association describes alluvial sands and fertile black soils in the Southern Barossa.4

    A Wine Australia study found that the timing of vine growth followed gradients in topography and soils, with temperature differences from topography and elevation as the main drivers.5 Vineyard data suggested dividing the Barossa Valley into three zones rather than one, and Eden Valley Shiraz separated most consistently from the other subregions.5

    Old vines

    Some Barossa vineyards date back to 1843, and the region is free of phylloxera.6 The Barossa Old Vine Charter, introduced in 2009, classes vines as Old Vine at 35 years, Survivor at 70, Centenarian at 100 and Ancestor at 125.6 During the vine-pull of the 1980s, key plantings were saved, particularly Shiraz and Grenache.6
