From 1400 on, two were the main, commercial sea routes of wine: Via the first route wines from Crete, Rhodes, the Peloponnese, western Asia Minor and Cyprus would head for western Europe. The second route would take wines from Crete, the Peloponnese, Macedonia and Thrace to Constantinople and the Black Sea. Predominant among the Greek wines traded, Malvasias reigned supreme, with Genoa and Venice setting their sights on it for its lucrative revenues.
