This week: What is the Barossa Old Vine Charter? Is there any other systems like it in the world of wine?
The Barossa Old Vine Charter was originally developed by Yalumba in an effort to classify and celebrate the old vines that were unaffected by phylloxera and survived 1980's vine pull schemes. In the Australian podcast, I found it interesting that many of the growers noted that despite surviving phylloxera and the vine pull scheme, the vine itself wouldn't be around unless it produced great fruit. The old vine charter is self regulated and contains 4 levels:
Old Vine - 35 years
Survivor Vine - 70 Years
Centurion Vine - 100 Years
Ancestor Vine - 125 Years
As for other schemes in the world:
