This is a guide to Australia's new Geographical Indications System, which has defined all of Australia's prominent wine areas, dividing the country into wine zones, regions and sub-regions, all of which are mapped. It stresses the regionality of Australia'a wines - expected to become more and more important in upmarket domestic and export sales - and deals with basic concepts of climate and topography and the suitability of grape varieties for various regions. There are also ratings and notes for all the wineries and vineyards within each zone, region and sub-region.
