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 between 1:1 and 1:3.
A bijou is a mixed alcoholic drink composed of gin, vermouth, and chartreuse.
 Bijou means "jewel" in French.
 It is said to have been invented by Harry Johnson.
 This cocktail is called Bijou because it combines the colors of three jewels: gin for diamond, vermouth for ruby, and chartreuse for emerald.
 An original-style Bijou is made stirred with ice as Harry Johnson's 1900 "New and Improved Bartender Manual" states "mix well with a spoon and serve."
 This recipe is also one of the oldest in the manual dating back to 1890s.
A fruit cup, also known as a summer cup, is traditionally an English speciality drink designed to be made into a long drink with addition of a soft drink such as lemonade or ginger ale.
 Most commonly, these are gin-based, although there are some varieties based on other spirits such as vodka.
 The base gin is flavoured with various herbs, spices, fruits, and botanicals as well as its strength reduced.
 Fruit cups are typically marketed for the summer months, served with fruit as a cocktail garnish to the drink and to improve the flavour; recommendations include apple, orange, strawberry, lemon, lime, cucumber, mint, and borage leaves.
The Chicago Cocktail is a brandy-based mixed drink probably named for the city of Chicago, Illinois.
 It has been documented in numerous cocktail manuals dating back to the 19th century.
 Chicago restaurant critic John Drury included it in his 1931 guide "Dining in Chicago", noting that it had been served at the American Bar in Nice and the Embassy Club in London.
 Whether it originated in Chicago is unknown.
Tonic water (or Indian tonic water) is a carbonated soft drink in which quinine is dissolved.
 Originally used as a prophylactic against malaria, tonic water usually now has a significantly lower quinine content and is consumed for its distinctive bitter flavour.
 It is often used in mixed drinks, particularly in gin and tonic.
The Clover Club Cocktail is a cocktail consisting of Gin, Lemon Juice, Raspberry Syrup, and an egg white.
 The egg white is not added for the purpose of giving the drink flavor, but rather acts as an emulsifier.
 Thus when the drink is shaken a characteristic foamy head is formed.
The gimlet (pronounced with a hard 'g') is a cocktail made of gin and lime juice.
 A 1928 description of the drink was: "gin, a spot of lime, and soda".
 The description in the 1953 Raymond Chandler novel "The Long Goodbye" stated that "a real gimlet is half gin and half Rose's lime juice and nothing else".
 This is in line with the proportions suggested by "The Savoy Cocktail Book" (1930) which specifies one half Plymouth Gin and one half Rose's Lime Juice Cordial.
 However, modern tastes are less sweet, and generally provide for at least two parts gin to one part of the lime and other non alcoholic elements (see recipes below).
A Sweet Melissa is a gin-based cocktail that was named by its creator, Daniel Bouie, after his wife Melissa Chabran Bouie.
 Sweet Melissa is made with gin, tonic water and a splash of Jack Daniel's in a short glass of ice.
 Care must be taken not to add too much whiskey to this gin & tonic beverage.
Piscola or Combinado Nacional (national mix) is a highball cocktail, made of pisco and most commonly a cola drink, that is popular in Chile.
 A piscola may be "black" or "white" depending if it is mixed with a cola or ginger ale, Tonic, Sprite or a similar soft drink.
 The drink is prepared by filling a highball glass with ice and then adding pisco followed by the soft drink in a proportion ranging from 1:1 to 1:3.
 Sometimes slices of lemon or key lime may be added.
 In Chile, February 8 has been celebrated as the "day of the piscola" since 2003.
A cocktail is a mixed drink typically made with a distilled beverage (such as, gin, brandy, vodka, whiskey, tequila, cachaça or rum) that is mixed with other ingredients.
 If beer is one of the ingredients, the drink is called a beer cocktail.
