Romulan ale

An infamous blue alchoholic beverage with a powerful kick, the drink has been banned in the United Federation of Planets since before 2285 and is still not a commonly known commodity.

It was unavailable even for replication aboard the Enterprise-D in 2366, to defecting Romulan Admiral Jarok's dismay.

A shipment hijacked by Fallit Kot  around 2362 landed him eight years in a Romulan labor camp after middleman Quark turned on him.
