The Barossa Grounds Project was established in 2008 to evaluate the variations in wine style across the Barossa Zone. This collaborative undertaking, led by the Barossa Grape & Wine Association and including the participation of South Australia’s leading soil scientists and viticulturists, wine critics, PIRSA and many of the Barossa’s most experienced winemakers, involved the collection of climatic data, analysis of soil profiles across the Barossa and Eden Valleys, controlled winemaking studies and annual tasting reviews.
The Australian Geographical Indications defines the official boundaries of the Barossa Zone, its Regions Barossa Valley and Eden Valley, and the Sub-region of High Eden.
The Barossa Grounds Project identified three distinctive Grounds within the Barossa Valley Region – Northern Grounds, Central Grounds and Southern Grounds. Two smaller grounds, Eastern Edge and Western Ridge, are also acknowledged.
