Cointreau (UK: /ˈkwɒntroʊ, ˈkwɑːn-/, US: /kwɑːnˈtroʊ, kwæ̃ˈ-/,[1][2][3] French: [kwɛ̃tʁo]) is a brand of orange-flavoured triple sec liqueur produced in Saint-Barthélemy-d'Anjou, France.

[9][10] The production methods and recipe are a family secret, but public tours of the facility are offered.

[11][12] In addition to being consumed neat (or often on ice), Cointreau is used in many popular cocktails.

The official IBA recipes for the margarita, Corpse Reviver #2, and the cosmopolitan include Cointreau.

In early 2008, the burlesque entertainer Dita Von Teese became the new face of Cointreau's "Be Cointreauversial" advertising and marketing campaign,[16] a campaign created in 2003[17] by the New York advertising agency KraftWorks.
