Cloves are a spice derived from the flower buds of the clove tree, Syzygium aromaticum. Known for their warm, sweet, and slightly bitter flavor, cloves are a versatile ingredient in both culinary and beverage contexts. When used in the realm of cocktails, cloves can add a rich depth of flavor that complements a variety of spirits and mixers. Their distinctive taste pairs particularly well with warm spices like cinnamon and nutmeg, making them a popular choice in spiced cocktails and holiday drinks.

In the context of alcohol, whole cloves are often used in infusions and syrups to impart their aromatic qualities. For instance, they might be simmered with simple syrup to create a spiced syrup that can be added to cocktails for an extra layer of flavor. Ground cloves can also be used to garnish drinks or to rim the edge of a glass for a festive touch. Classic cocktails like the Hot Toddy and the Mulled Wine often feature cloves as a key ingredient, enhancing their warmth and complexity.
