During Venetian rule, the islands of the Aegean and the Ionian sea, Crete and Peloponnese for a while, were occupied by the Venetians. For centuries Europeans had great appreciation for Greek wines, due to their quality and durability during long sea voyages. That was the reason why the ships of the Franks and Venetians began to carry more and more wines from Crete, the Cyclades and Monemvasia. The most requested wine of the era was the Malvasia wine (nowadays PDO Monemvasia-Malvasia), the trading of which, was one of the biggest wine transport activities in global history of wine. The export boom of Greek wines during Venetian rule came to a definite end with the absolute domination by the Turks of the mainland and islands of Greece.
