Aldebaran whiskey was a strong, green alcoholic beverage, favored by Guinan, who kept a bottle behind the bar in Ten Forward. It was a gift from her friend, Jean-Luc Picard. In 2369, Data served Montgomery Scott the drink of Aldebaran whiskey, although he was unsure of its characteristics beyond its green color. Scotty found this beverage quite satisfying and drank most of the bottle himself, although he shared a couple of glasses with Picard. (TNG: "Relics" ) Several barrels of Aldebaran whiskey were kept in storage in several of Deep Space 9's cargo rooms. (DS9: "Explorers", "Distant Voices")
