Pineapple liqueur, a type of fruit liqueur, is a sweet and tropical spirit that infuses the rich, vibrant flavors of ripe pineapple with a smooth alcoholic base. Typically, it has a lower alcohol content compared to hard liquors, making it a versatile ingredient in a variety of mixed drinks and cocktails. The liqueur is often crafted by macerating fresh pineapples in a neutral spirit or rum, then sweetening and sometimes aging the mixture to enhance its depth and complexity.

In the context of cocktails, pineapple liqueur can add a burst of tropical sweetness and a hint of tartness. It pairs well with a range of other spirits including vodka, rum, and tequila, making it a popular choice for summery, refreshing drinks. Classic cocktails like the Piña Colada or the Pineapple Martini are elevated by its inclusion, while modern mixologists often experiment with pineapple liqueur to create innovative, exotic concoctions. Its bright flavor profile also complements various mixers such as coconut milk, citrus juices, and soda, allowing for endless creativity in cocktail crafting.
