Mint liqueur is a type of flavored alcoholic beverage that is infused with mint leaves to provide a fresh, cool, and slightly sweet taste. It is often used in the context of cocktails to add a refreshing and aromatic element. The liqueur is typically clear or green in color and has a lower alcohol content compared to spirits like vodka or gin, making it an ideal ingredient for mixing into various drinks.

When used in cocktails, mint liqueur can enhance the overall flavor profile by imparting its distinctive minty essence. It pairs well with a variety of ingredients, including citrus juices, other liqueurs, and even coffee. Classic cocktails like the Grasshopper and the Stinger often feature mint liqueur as a key component, showcasing its versatility and ability to complement both sweet and savory flavors. Mint liqueur is also sometimes used to add a touch of elegance to dessert cocktails and after-dinner drinks.
