British control of colonial India required the ability to combat malaria, so Brits in India consumed powdered rations of quinine in the form of “Indian tonic water.” By the 1840s, British citizens and soldiers in India were using 700 tons of cinchona bark annually for their protective doses of quinine. They added gin to the liquid to cut its bitter taste and, most certainly, for its intoxicating effect. And the gin and tonic cocktail was born. It became the drink of choice for Anglo-Indians and is now of course a universal staple on bar tabs worldwide.
