The Imperial Cocktail

How the gin and tonic became the British Empire’s secret weapon.

The gin and tonic is having a moment. From Spain—where gin and tonics are practically the national drink—to our summer shores, the venerable G-and-T is everywhere. House-made tonic is on the menu in restaurants from coast to coast, and in many fine bars gin and tonics come in dozens of varieties, with special tonics and fruit garnishes matched to distinctive artisanal gins.

Of course, a lot of classic cocktails are enjoying a resurgence—part Mad Men, part the boom in distinctive small-batch spirits, and part the waning fad of faux speakeasies with handcrafted bitters and bartenders in arm garters chipping away at blocks of ice.

But the gin and tonic is different. For one, it requires no unusual ingredients, and it’s very simple to make. More interestingly, the gin and tonic has a storied history that places it at the heart of the largest empire the world has ever known. Indeed, it is not too much of a stretch to say that the gin and tonic was as essential a weapon for the British Empire as the Gatling gun. No less an authority on imperial power than Winston Churchill once declared, “The gin and tonic has saved more Englishmen’s lives, and minds, than all the doctors in the Empire.”

What was the source of the gin and tonic’s great power? As is sometimes said of tequila, the gin and tonic is not just a drink; it’s a drug.

The story begins with the jewel of the British Empire: India. British India comprised both more and less than modern-day India. More, in that it included large parts of what are today Pakistan and Bangladesh. Less, in that much of India under the British Raj was quasi-independent, in so-called princely states that were nominally sovereign but largely under England’s thumb. India was so important to the empire that in 1876 Queen Victoria added the moniker “Empress of India” to her title. Her successors continued that practice right up till 1948, under George VI (he of The King’s Speech fame).

Controlling India, in short, was central to the British Empire and to Britain’s sense of itself as the world’s leading power. What allowed Britain, a small island far off in the northern reaches of Europe, to rule over the vast semi-continent of India for so long is a subject of some debate. But in Jared Diamond’s famous words, Europe’s military superiority was built on a mix of “guns, germs, and steel.”

Guns and steel clearly favored powers like Britain. These innovations allowed Britain (and other European countries) to deploy weapons such as machine guns at a time when many societies around the world still used swords and spears. But germs were more equivocal. Malaria in particular was a virulent killer of colonized and colonizer alike. While malaria has a long history in Europe, it began to be eradicated in the 19th century, and even earlier it was never as deadly as it was in tropical locations. So as Europeans established colonies in the tropics, they faced a serious and often mortal threat from the mosquito-borne disease. Soldiers and civilian officials alike succumbed to it.

In the 17th century, the Spanish had discovered that indigenous peoples in what is now Peru used a kind of bark to address various “fevers.” Stripped from the cinchona tree, the bark seemed to work well for malaria. The “Jesuit’s bark,” as it was known, quickly became a favored treatment for malaria in Europe. (Before the discovery of the cinchona tree, European malaria remedies included throwing the patient head-first into a bush in the hope he would get out quickly enough to leave his fever behind.)

Eventually it became clear that cinchona bark could be used not only to treat malaria, but also to prevent it. The bark—and its active ingredient, quinine powder—was a powerful medicine. But it was also a powerful new weapon in the European quest to conquer and rule distant lands.
