Tanqueray is a London Dry Gin, so called because of the distillation process, not the origin of the product and is primarily produced in Scotland for export to its largest market, the US.
London Dry Gin is made through double distillation of a neutral grain spirit with botanicals added during the second distillation.
Tanqueray Gin was initially distilled in 1830 by Charles Tanqueray in the Bloomsbury district of London. When Charles died in 1868 his son Charles Waugh Tanqueray inherited the distillery, which operated until it was severely damaged in World War II. Only one of the facilities survived the Axis bombing. The remaining one, now known as "Old Tom", has since been moved to Cameron Bridge, Scotland.
Tanqueray London Dry Gin is the original variant, launched in 1830; the key botanicals are juniper, coriander and angelica root. It is variously sold at 94.6 proof (47.3% abv) (e.g., USA and Canada), 75.4 proof (43.1% abv) (e.g., in the UK and Sweden) and 80 proof (40% abv) (e.g., in Australia, Canada, and New Zealand). The top markets for sales are U.S. Canada, duty free, Spain, and Italy.
Whisky and More has imported the 43% European Tanquery
Gin and Tonic was introduced by the army of the British East India Company in India.
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, or lemon. The amount of gin varies according to taste. Suggested ratios of gin-to-tonic are 1:1, 1:2, 1:3, and 2:3
Commonly referred to as a "G and T", the Tanqueray specific version is a "T&T"
In the 18th century, tonic water which contained a large amount of quinine, was used to prevent malaria. The quinine however caused it to have a very bitter taste. Gin was added to make it more palatable. Tonic water sold today contains only a very small amount of quinine and is consequently much less bitter (and it is sometimes sweetened).
The flavor of the quinine complements the green notes of the gin (flavored with juniper), much as dry vermouth complements the gin in a classic martini.
Because of its connection with warm climates and its refreshing effects, gin and tonic is a very popular cocktail during the warmer months.
