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, gin and tonic is marketed pre-mixed in single-serving cans. In the United States, most bars will substitute soda water (from a soda gun) for the tonic; to get a real gin and tonic, mixologist Dale DeGroff recommends specifying bottled tonic. Alternatively, one can add tonic syrup to soda water.
It is commonly referred to as a "G and T" in the UK, USA, Canada and Ireland. Some brands will replace the word "gin" with their own brand or initial in recipes. For instance, "Sapphire and Tonic" for Bombay Sapphire, "Hendrick's and Tonic" for Hendrick's Gin (garnished with cucumber to further distinguish it), or "T&T" for Tanqueray.
In some parts of the world (e.g., German countries, France, Korea, Italy, Japan, Greece, Spain, Turkey, Belgium), it is called "Gin Tonic".
A "compressed" version of the gin and tonic uses a shaken mixture of gin, tonic syrup and lime which is served in a Martini glass is known as a "GT Turbo," originally created in 2010 by Purl Bar in London. 
Gin and tonic is traditionally garnished with a slice or wedge of lime, often slightly squeezed into the drink before being placed in the glass. In most parts of the world lime remains the only usual garnish; however, in the United Kingdom it has become common to use lemon as an alternative fruit, use of both fruit together is known as an "Evans". Although the origins of the use of lemons are unknown, their use dates back at least as far as the late 1930s. In addition lemons are often more readily available, and cheaper to purchase, than limes. The use of lemon or lime is a hotly debated issue  and while many brands, such as Gordon's, Tanqueray and Bombay Sapphire recommend the use of lime other industry experts such as the Master Distiller of Beefeater and the founder of Fevertree Tonic Water prefer lemon.
In India and other tropical regions, malaria was a persistent problem. In the 1700s it was discovered that quinine could be used to prevent and treat the disease, although the bitter taste was unpleasant. British officers in India in the early 19th century took to adding a mixture of water, sugar, lime and gin to the quinine in order to make the drink more palatable. Soldiers in India were already given a gin ration, and the sweet concoction inevitably made sense. Since it is no longer used as an antimalarial, tonic water today contains much less quinine, is usually sweetened, and is consequently much less bitter.
Gin and tonic is a popular cocktail during the warmer months.
In Spain, a variation on the drink called Gin Tónica has become popular. This differs from a traditional gin and tonic as it is served in balloon glass  or coupe glass with plenty of ice and a garnish tailored to the flavours of the gin. The drink could be fruit-based but the use of herbs and vegetables, reflecting the gins botanicals, are increasingly popular. The balloon glass is used because the aromas of the drink can gather at its opening for the drinker to more easily appreciate.
The popularity of this variation of the gin and tonic has led to the establishment of Gin Tónica bars, in which customers can choose their preferred gin, tonic, and garnish from a menu.
In popular culture
It is a curious fact, and one to which no one knows quite how much importance to attach, that something like 85% of all known worlds in the Galaxy, be they primitive or highly advanced, have invented a drink called jynnan tonnyx, or gee-N'N-T'N-ix, or jinond-o-nicks, or any one of a thousand or more variations on the same phonetic theme. The drinks themselves are not the same, and vary between the Sivolvian "chinanto/mnigs" which is ordinary water served at slightly above room temperature, and the Gagrakackan "tzjin-anthony-ks" which kills cows at a hundred paces; and in fact the one common factor between all of them, beyond the fact that the names sound the same, is that they were all invented and named before the worlds concerned made contact with any other worlds.
In the movie The Year of Living Dangerously, Colonel Henderson, when he first meets Guy Hamilton, complains when his gin and tonic is served with ice, explaining that only Americans drink it like that.
Oasis also mention the cocktail in their song "Supersonic": "I'm feeling supersonic, give me gin and tonic".
On the popular sitcom How I Met Your Mother, character Barney Stinson played by Neil Patrick Harris is often heard ordering a gin and tonic. On one occasion where he serves as a bartender, the audience learns that he does not know what the drink consists of.
Gin and Tonic is also the drink of choice for female hero, Cat, in Jeaniene Frost's Night Huntress Series.
