Wormwine was an alcoholic beverage popular in Ferengi culture. Drinking large quantities of wormwine often led the following day to a condition called being "worm-headed," presumably a state akin to being hung over.
Duwain, the daughter of Sleekback racing beetle breeder Nix, would often drink gallons of wormwine during parties with her father's beetlejockeys. (DS9 reference: Legends of the Ferengi)
