Minotaur Seed:
The drink is basically a suicide, or barmat special: remnants of all manner of raw liquor, mixed with a milky root substance alleged to give the imbiber "stamina." It's somewhat a rite of passage for young inductees into the city militia to take shots of it as a hazing ritual. Also as a twist, if you want the drink, you must pour it yourself. The catch is, the tasty blackout inducing concoction is stored in an oak barrel. That barrel is encased in a stone statue of a fearsome minotaur and to coax the spigot to open requires manual manipulation of the phallus of the statue, which for reasons noone can remember, is wearing a festive party hat.
