Cointreau is a French orange liqueur, often a component of popular cocktails like margaritas and cosmopolitans. While the recipe remains a closely held family secret, the concoction is distinguished as much by its intense, sweet, bitter orange taste as it is by its bottle.

The orange liqueur brand has recently announced a redesign of its signature square bottle, the first noteworthy change in almost 140 years, according to Cointreau.
