"It is... it is... It is green"

Aldebaran whiskey is a green-colored alcoholic beverage. A whiskey from Aldebaran III, the beverage appears to be an "acquired taste" to some, and also appears to be a very potent beverage. (DS9 short story: "... Loved I Not Honor More")

Captain Jean-Luc Picard once obtained a bottle of Aldebaran whiskey that had been produced around stardate 36455. The whiskey produced on the northern continent that year was considered to be a very good beverage, as there had not been too much rain that year. Captain Picard eventually gave that bottle to Guinan, who brought in on board the USS Enterprise-D and kept it in Ten-Forward for a special occasion. Lieutenant Commander Data served that bottle to Montgomery Scott shortly after Scott had been rescued from the USS Jenolen. By the time Data served the bottle to Scott the label had faded, so he was unable to identify the beverage beyond the fact that it was green. Scott took the bottle to the holodeck, and shared it with Captain Picard, who filled Scott in on the origins of the bottle. (TNG novelization: Relics)
