Aristeon Olive Press
A charming tour is run here by the most famous olive oil brand on Zakynthos, Aristeon. Many of the island's famed dopia olive trees are thought to be more than 2,000 years old, and this deep dive into local oil production in Zakynthos follows the process from branch to bottle.
If you want to see an ancient dopia in real life, head to the village of Exo Chora, on the northwest coast. At its center grows what's known locally as the "elephant tree," a gnarled wonder thought to be some 2,000 years old.
