For the Antarean variety, please see Antarean brandy.
Altairian brandy was a blue-colored alcoholic beverage from the Altair system.
Jean-Luc Picard brought a bottle of Altairian brandy as a gift for Lwaxana Troi in 2364, which Mr. Homn downed in one swig. (TNG: "Manhunt")
The bottle of Altairian brandy is a reuse of the bottle of Romulan ale that Dr. Leonard McCoy gave to Admiral James T. Kirk for his birthday.
