Abbreviation for the Greek wine quality level "Onomasía Proelefséos Anotéras Piótitos" (designation of origin of higher quality), valid until 2009. This corresponds to a quality wine. OPAP wines are marked with a red banderole running across the cork. Another quality level is OPE (Onomasía Proelefséos Eleghoméni = controlled designation of origin). The production regulations are identical to OPAP, but in addition there are higher requirements regarding sugar content. Sweet wines from the historical areas of Kefallonia, Limnos, Patras, Rhodes and Samos are thus declared. The OPE wines are marked with a blue banderole running across the cork.
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.Andreas Essl
