Citrus garnishes — including twists, wheels, wedges, and zest — serve both a visual and a sensory purpose in cocktails, adding a burst of aromatic citrus oil and a pop of vibrant color. A well-expressed lemon or orange twist releases volatile oils onto the surface of a drink, subtly shifting its aroma and flavor profile before the first sip. They are among the most versatile and universally used garnishes in mixology, complementing everything from delicate spritzes to bold, spirit-forward stirred cocktails.
