Data confidence level:
This FACT indicates the number of wine producing regions within each state and territory. Wine-producing regions, or growing regions, are areas where vineyards are planted. Wine grapes mostly grow between the 30th and the 50th degree of latitude, in both the Northern and Southern hemispheres. Grapes will sometimes grow beyond this range and minor amounts of wine are made in some very unexpected places. The state with the highest number is South Australia, at 17 wine regions. The state/territory with the lowest is the Australian Capital Territory, at just 1.
