Lemon liqueur, often referred to as limoncello, is a sweet, lemon-flavored alcoholic beverage primarily made from lemon zest, alcohol, water, and sugar. Known for its vibrant, tangy flavor, it captures the essence of fresh lemons, making it a versatile ingredient in the world of mixology.

When used in cocktails, limoncello (lemon liqueur) brings a refreshing citrus note that can enhance various drinks. It pairs well with other spirits like vodka, gin, and tequila, and is often used in recipes such as the Lemon Drop Martini, Limoncello Collins, or simply enjoyed on its own as a chilled digestif. Its bright flavor and aromatic qualities make it a popular choice for adding a zesty kick to both classic and innovative cocktails.
