Which garnish is typically used for a martini?

The typical garnish for a martini is an olive. This choice aligns with the classic presentation of a martini, which is often served chilled and stirred or shaken, and garnished with an olive to enhance the drink's character. The olive not only adds a touch of flavor but also embodies the traditional style and sophistication associated with martinis.

While other options, like a lemon twist or a cherry, can also be used in variations of the cocktail, the olive remains the most iconic and standard garnish for a traditional martini. The presence of an olive signifies the drink's nature and is a hallmark of its classic representation in bars and restaurants.

Each of the alternatives—such as the cherry or the orange slice—can complement different cocktails or variations, but they do not convey the classic essence of a martini in the same way that an olive does.
