National Crème de Menthe Day is observed worldwide on September 15, celebrating the mint-flavored liqueur known as crème de menthe, which translates from French as “mint cream.” This sweetened alcoholic beverage is flavored with Corsican mint and comes in two varieties: green and colorless (white). The traditional method of making crème de menthe involves soaking dried mint leaves in grain alcohol for several weeks, followed by filtering and adding sugar. To celebrate, people often host cocktail parties featuring drinks that include this liqueur, such as the Grasshopper and Stinger cocktails. The Grasshopper is made by shaking together crème de menthe, crème de cacao, and fresh cream, while the Stinger combines Cognac and crème de menthe, typically using the white variety.
