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