This variety of raisin has been produced since the 13th century in the ancient city of Aigio in the northern Peloponnese, on the hills overlooking the Gulf of Corinth. The Corinthian raisin is made from small, sweet, seedless grapes of the black Vostizza variety that have been dried naturally in the open air.
These raisins are sorted manually and cleaned several times before final packaging, and they are sometimes glossed with vegetable oil to make them shinier. Corinthian raisins are very small and have an intense flavor, with an almost 75% sugar content.
