AOP / AOC
Official mentionProtected Designation of Origin: the most tightly regulated tier.
What it guarantees
A precisely delimited geographical area, a list of authorised grape varieties, a maximum yield per hectare, regulated winemaking methods and an approval tasting before release.
What it does not guarantee
Nothing about actual taste quality or the environment. An AOP wine can be mediocre, and it imposes no organic practice whatsoever.
