Which ingredient is used for garnish in a Manhattan cocktail?

The garnish traditionally used in a Manhattan cocktail is a cherry. This choice stems from the overall flavor profile of the Manhattan, which is a whiskey-based drink typically mixed with sweet vermouth and bitters. The sweetness of the cherry complements the rich, robust characters of the whiskey and vermouth, adding a visually appealing touch as well as a slight burst of sweetness when consumed alongside the drink.

While garnishes like olives, mint, and a lemon twist are popular in other cocktails, they do not align with the Manhattan’s classic presentation or flavor combination. In contrast, the cherry has become synonymous with the Manhattan, making it an integral part of the cocktail.
