What is a common garnish for a Gin and Tonic?

A lime wedge is a classic garnish for a Gin and Tonic. The lime not only adds a burst of fresh citrus flavor that complements the botanicals in the gin, but it also enhances the overall drinking experience by providing a visual appeal and a hint of acidity that balances the drink's sweetness and bitterness. The aromatics released from the lime can elevate the refreshing quality of a Gin and Tonic, making it more enjoyable.

While other garnishes like a lemon slice or cucumber slice might occasionally be used in variations of gin cocktails, the lime wedge is traditionally associated with this particular drink and is generally considered the standard garnish. An olive, on the other hand, is typically reserved for drinks like martinis and does not pair as well with the flavor profile of gin and tonic.
