Cappuccino, a popular coffee-based beverage, is not traditionally an ingredient in cocktails, but its components—espresso, steamed milk, and milk foam—can be creatively used to craft unique alcoholic drinks. The rich, bold flavor of espresso pairs well with various spirits, while the creamy texture of steamed milk and foam adds a luxurious mouthfeel.

When used in cocktails, the key ingredient is often espresso (a strong coffee), which provides a robust coffee flavor. This can be combined with liqueurs like Kahlúa or Baileys for a creamy, sweet profile or with vodka for a more intense, bold taste. The milk foam can be used as a garnish to add a frothy, visually appealing top layer to the cocktail.
