A cocktail garnish is a decorative element added to a drink to enhance its appearance and flavor. Common garnishes include citrus slices, herbs, and cherries, which can complement the drink's ingredients. They not only make the cocktail visually appealing but can also provide aromatic qualities that enhance the drinking experience. Garnishes can vary widely depending on the type of cocktail. For example, a Mojito might be garnished with fresh mint leaves, while a Martini often features an olive or a twist of lemon peel. The choice of garnish can reflect the cocktail's style and the bartender's creativity.
