Abbreviation of former designations of several wine-growing countries for " quality wine of specified regions with controlled origin". They were replaced by PDO with the EU wine market regulation valid from August 2009. However, the old, traditional designations are still permitted in some countries. See also under quality system.
The glossary is a monumental achievement and one of the most important contributions to wine knowledge. Of all the encyclopaedias I use on the subject of wine, it is by far the most important. That was the case ten years ago and it hasn't changed since.
