Many of the great wine regions of the world are designated UNESCO World Heritage Sites. I put together a list of them.
UNESCO World Heritage Sites – Wine Regions:
Loire Valley, France
Middle Rhine River/Mosel, Germany
Douro Valley, Portugal
Georgia wine region
This may not a complete list because there is no “quick” way to get a list from UNESCO and requires digging around a bit more. I will add to it if I find more regions.
