Chech'tluth
Chech'tluth was an extremely potent Klingon alcoholic beverage that looked to be smoking. 

Worf served a cup of chech'tluth to the Bringloidi leader Danilo Odell in 2365, after ODell found replicated whiskey to be lacking. Upon sipping the beverage he complimented it by stating, "now that's what I call a wee drop of the creature." ()
