The red grape Petrokoritho Mavro comes from Greece from the island of Corfu. She is almost extinct there. From the white-berry mutation Petrokoritho Lefko (also Petrocoritho or Pietro Corinto), however, still has small stocks. The late-ripening vine is relatively resistant to disease. It produces acidic white wines with moderate alcohol content. The variety is in small stocks Corfu (Kérkyra), as well as on Peloponnese and in Central Greece grown on Euboea. In 2010, however, no stocks were reported (Statistics Kym Anderson ).
