Europe protects origin of products using the PDO label, so Greek yoghurt can only come from Greece (and maybe Bulgaria?), Halloumi can also come from Cryprus, Parmigiano is only from Italy and so on, the list goes on forever.
But at the same time you can have Greek-style yoghurt and grilling cheese that some people would consider basically equivalent.
Do you actually care about the the PDO label?
