Crème de Menthe is a mint-flavored liqueur that is commonly used in various cocktails and desserts. It comes in two varieties: green and white (or clear). The green version is typically colored with mint leaves or artificial coloring, while the clear version lacks any additional coloring, making it more versatile for certain recipes where color might be a concern.

In the context of cocktails, Crème de Menthe adds a refreshing minty flavor and a bit of sweetness. It's a key ingredient in classic cocktails such as the Grasshopper, which combines green Crème de Menthe with white Crème de Cacao and cream, and the Stinger, which blends white Crème de Menthe with brandy. The liqueur's distinctive mint taste can enhance a variety of drinks, making it a popular choice for both professional bartenders and home mixologists.
