Yridian ale was an alcoholic beverage created by the Yridians.

In 2374 when it was believed that Morn had died, Quark sold Yridian ale to the attendants of his funeral, telling them it was "Morn's favorite", as it was Lurian tradition to give food and drinks to the deceased to sustain them in the afterlife. (DS9: "Who Mourns for Morn?")
