Hector spent seemingly hours trying to locate the Beer Academy. If they were ever in Plaka, the premises closed yonks ago. The found premises on Stournari, near Omonia, were passed on one’s way to/from Bierhof.
On two visits, I never bought a Bier. Draught Warsteiner does not excite. The bottles I asked for from their list were not available. Unsurprisingly, these premises closed.
Try Padre Craft Beer Taproom (Stournari 17a, Athina 106 83) instead if one is in this area.
Update 2024
Another incarnation has opened, well out of town at Chalandri: Karella 45, Chalandri 152 33. Here the emphasis appears to be as much on food.
Beer Academy opens daily at 13.00 until late.
