Some of those "protected wines" didn't even exist before the agreement and no one cares if they are protected, or not.
This is basically a "in exchange of a few thousand names [1] that you can never use even if you produce an identical product, we will protect some names many of which not even you care about, or weren't even ever used before this agreement".
2. That "protected spirit"? That's the new invented name for cognac.
As wikipedia puts it [2], emphasis mine:
=== start quote ===
Divin - represents the name, patented in the Republic of Moldova, of the country's brandy, produced in conformity with the classic technology of cognac production.
=== end quote ===
So, it's produced like cognac, looks like cognac, has the same ingredients as cognac, smells like cognac, tastes like cognac, but don't you dare call it cognac, invent a new non-sensical name to call it something else but cognac.
The same goes for dozens of other names. And we're talking only about wine and spirits. Imagine if no country could call whisky, well, whisky, and each country had to invent their own name for it.
