Great insights from Blake Leja, Wanda Cole-Nicholson, Brandon Ford and Karl Kazaks last week on the 1er cru vineyards of Beaune AOP. Thanks for your contributions!
This week: Barossa
What are the sub regions and the major geographic features? What impacts do these have on the wines?
The GI's of Barossa are Barossa Valley and Eden Valley GI's. The Barossa Ranges is the major natural feature. This Range is the main source for the North Para River as well as well as Jacob's Creek. The Barossa Ranges are east of the Barossa Valley and are very windy and cool. Allowing for varieties such as Riesling to be planted. Higher elevation assists in keeping acid levels elevated.
In support of your statements: Eden valley, which is to the East of the Barossa Valley and of a higher elevation , riesling is indeed the number 1 planted grapes (over 35%). In the Barossa Valley where the altitude is slightly lower and average temperature warmer, Shiraz is the number planted grapes (over 55%) and riesling is not significant here.
I believe I may have awkwardly worded my response. I was not suggesting Barossa Valley grows Riesling. My statement was claiming that due to the elevation of the Barossa Ranges. Riesling is grown there because of the elevation.
