Chech'tluth

From Memory Alpha, the free Star Trek reference.

Chech'tluth is an extremely potent Klingon alcoholic beverage that looks to be smoking. Worf served a cup of chech'tluth to the Bringloidi leader Danilo Odell in 2365, after O'Dell 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." (TNG: "Up The Long Ladder")

Worf tells the replicator "joq tlutlh" when he requested the drink, which literally means "bold drink", as defined by the thlIngan Hol translation from Marc Okrand's "The Klingon Dictionary".
