Wine. A big subject that deserves its own app, but here are a few notes on special Greek grapes, classifications and wine words you may need. Some of the oldest signs of wine-making have been found in Greece, dating back to c. 6500 BC.
Even so, Dionysos, the god of wine (and theatre, and ecstasy before it became a drug, although he'd probably be the god of that, too!) was a johnny-come-lately to Olympus. But in many ways he was the most interesting of all the gods.
But Greek wine wasn't always interesting. For travellers in the 1960s and 70s, ordering krasí in a taverna usually meant either retsína or not retsina, which would be white or red Demestica from the Peloponnese, which elicited much merriment among British tourists who called it 'Domestos' after the bleach company (it wasn't that bad, and Achaia Clauss still sells a much improved version and exports quite a bit to Germany).
