What is the typical garnish for a gin and tonic?

The typical garnish for a gin and tonic is a lime wedge. This choice enhances the drink both visually and flavor-wise. The acidity of the lime complements the botanicals in the gin, making the drink refreshing and well-balanced. The lime's bright, zesty character also adds an aromatic element that enhances the overall tasting experience, helping to bring out the nuanced flavors of both the gin and tonic water.

While other garnishes can be used with cocktails, they do not align with the traditional presentation of a gin and tonic. A lemon twist may add some citrus notes, but it is less common and does not provide the same complementary effect as lime. A cherry is typically associated with sweeter cocktails, while an olive is usually found in drinks like martinis. Therefore, the lime wedge stands out as the most appropriate and classic garnish for a gin and tonic.
