Cognac

Cognac is a brandy of French origin.

Cognac was illegal on Terok Nor during the Occupation of Bajor, although Quark kept a bottle underneath his bar area. 

In 2372, Joseph Sisko wanted to open a bottle of cognac when Benjamin Sisko returned home. 

In 2376, Quark served Cognac at a reception for Federation, Bajoran and Cardassian delegates on Deep Space 9.
