Abbreviation for "Prostatevomenis Onomasías Proelefsis" (protected designation of origin), the highest wine quality level in Greece since 2009. It corresponds to quality wine and replaced the alternatively possible levels OPE and OPAP. The second highest level is PGE (country wine). See also in detail under Quality System.
Serious sources on the internet are rare - and Wine lexicon from wein.plus is one such source. When researching for my articles, I regularly consult the wein.plus encyclopaedia. There I get reliable and detailed information.
