oinómelo

Honey-spiced wine, also known as κρασόμελο (krasómelo) was first mentioned in Homer, as the wine offered to Odysseus by the enchantress Circe. Hippocrates, father of medicine, who first discovered its therapeutic effects, highly recommended it has a restorative, and many an ancient Greek and Roman swore by it.

It is similar to mulled wine, but is often drunk cold as well as hot. Several companies across Greece sell it ready to drink if you don't want to make your own, including the specially dedicated Oinomelos.
