A gin and tonic is a highball cocktail made with gin and tonic water poured over ice. It is usually garnished with a slice or wedge of lime. The amount of gin varies according to taste. Suggested ratios of gin to tonic are 1:1, 1:2, 1:3, and 2:3.
In some countries (e.g. UK), gin and tonic is also marketed pre-mixed in single-serving cans. In the United States, most bars "use soda out of a gun that in no way, shape or form resembles quinine water", according to bartender Dale DeGroff. To get a real gin and tonic, DeGroff recommends specifying bottled tonic. Alternatively, one can add tonic syrup to soda water.
