Romulan ale
From STNE Wiki
Romulan ale was a highly intoxicating alcoholic beverage of Romulan origin with a characteristic blue color (this could range from a pale sky blue to a dark midnight blue, depending on the "vintage"). It took a while to ferment and was also used for medicinal purposes.
Although it was illegal in the Federation from at least the early 2280s to the late 2370s, in actual practice many Starfleet officers had sampled it at one point or another. A rare exception was Admiral William Ross.
Admiral James T. Kirk received a bottle of Romulan ale, dated 2283, as a birthday gift from Doctor Leonard McCoy in 2285.
Captain James T. Kirk was able to procure some for his crew, and served it at a state dinner with Gorkon in 2293. When pressed by one of the Klingons on its illegality, he wryly noted it was, "one of the advantages of being a thousand light years from Starfleet Headquarters." However, the ensuing hangover convinced him to order that the drink no longer be served at diplomatic functions.
In 2362, Fallit Kot hijacked a shipment of Romulan ale. He was sentenced to eight years in a Romulan labor camp.
In 2366, the replicators aboard the USS Enterprise were not capable of replicating Romulan ale; it would have required programming the devices with the molecular structure of the beverage. The recipe was not readily available due to the lack of communication and information between the Federation and the Romulan Empire.
Romulan ale was even a challenge for species as stout as the Klingons, who were usually quite resistant to the effects of alcohol. After drinking a sizable amount of Romulan ale in celebration of William T. Riker and Deanna Troi's wedding in 2379, Worf, obviously suffering its effects, stated that "Romulan ale should be illegal", to which Geordi La Forge replied, "It is."
Romulan ale briefly became legal in the Federation during the Dominion War when the embargo was lifted due to the alliance between the Federation and the Romulans. However, by 2379, Romulan ale was prohibited again.
