Cointreau is a French orange liqueur (triple sec) crafted from a proprietary blend of sweet and bitter orange peels, prized for its crisp, balanced citrus flavor and transparent spirit profile. Launched in 1875 and recognized by its signature square bottle, Cointreau is a benchmark in cocktails—favored in classics like the Margarita and Cosmopolitan—for its versatility and artisanal distillation heritage.
