What does PDO mean on Greek wine labels?

ΠΟΠ (Protected Designation of Origin) means Protected Designation of Origin. On Greek wine labels, it indicates that the wine comes from a specific recognized region and adheres to specific regulations, such as production area, permitted grape varieties, and winemaking methods. For example, a wine labeled ΠΟΠ Santorini is linked to Santorini and its regional specifications — it's not just a wine using the island's name for marketing. This is why ΠΟΠ is important: it protects the identity of the place and helps the consumer better understand what they are buying.
