It is summer, the perfect time to enjoy a GT. Thanks to the British army, Gin & Tonic are two inseparable ingredients. Tonic water is not a complex product, it is essentially quinine, carbonated water, and sugar. Just like with gin, adding botanicals makes for a lot of interesting tastes.
The history of tonic water
Tonic water was first made by British soldiers in East India in the early 19th century as a way to consume quinine which was used against malaria. Quinine has an extremely bitter flavor. The Brits mixed it with soda and water in order to reduce the bitterness. The mix was still too bitter to be enjoyed. Being British, they solved this by adding gin. Without knowing it, the British army had created what may be the world’s most famous, and easy to make, cocktail.
The first commercial production was done in 1858 by Erasmus Bond. 20 years later, Jacob Schweppe started to produce what we today know as Schweppes Indian Tonic.

Lately, as gin has become more and more popular, we have seen a flurry of new tonics arrive on the scene. A few examples are listed below:
- Fever-Tree, US brand launched in 2005.
- Q Tonic, US brand founded in Brooklyn in 2006.
- Thomas Henry, German brand launched in 2010.

Quinine
Quinine is a medication used to prevent and treat malaria. Today this treatment is no longer recommended due to the many side effects. Quinine was first extracted from Peruvian cinchona bark around 1630. It was then used to treat fever. This is the source of the brand name Fever-Tree. Today tonic water has a quinine content of less than 83 mg per liter. The daily medical dose is between 500 and 1000 mg per liter.
Quinine prove to be an essential ingredient in the pacific during world war II. The last American plane to fly out of the Philippines before it was taken over by the Japanese carried some 4 million quinine seeds.

Fun facts
