Inscriptions discovered on the northern Aegean island of Thassos contained legislative texts which decreed that the wine produced be transported in sealed amphorae. The inscriptions also reveal that local laws forbade Thassos ships transporting wine from foreign places to approach the island. That was how the lawmakers of Thassos monitored, protected, and promoted the island’s wine. In that sense, they were the first to create the world’s first PDO wine(around 475 BC). The practice of sealing the amphorae at the handles was applied by other famous winemaking areas as well which, thus, established the first way of marking and authenticating wines. However, that did not stop certain other areas from selling wines in amphorae whose handles carried fake seals bearing the names of well-known Greek wines.
