Langour

From Memory Alpha, the free Star Trek reference

Langour was a type of valued pink alien beverage.

While preparing to conduct an illegal purchase from the Miradorn twins Ah-Kel and Ro-Kel in 2369, Quark had his brother Rom bring a flask of his special langour for the occasion. (DS9: "Vortex")

A cut line specified langour to be of Cardassian origin.
