Warnog

Warnog is a Klingon alcoholic beverage, not quite as ceremonial or popular as bloodwine.

Warnog was available at O'Dell's bar in the Aneher II neutral zone between the Federation and Klingon encampments.

In December of 2267, after imbibing a large amount of warnog, K'Vak got into a bar brawl with other drunk Ronald Saygar. (TOS novel: "The Case of the Colonist's Corpse")
