Tonic Syrup: for Gin, Vodka or Rum and Tonics

Making tonic water at home and in bars became a widespread fashion in the early 2000’s. An internet search for ‘DIY tonic water’ will result in a number of recipes. Jeffrey Morgenthaler posted a recipe in 2008, (found here), which became one of the most popular. Since then, he has published a newer version in his book, The Bar Book: Elements of Cocktail Technique. I like his new version, which can be found on line here, because he separates the aromatics from the quinine. This lends itself to easy modification. My recipe for tonic syrup for use with gin differs only slightly from his.

What has become apparent over the last decade is that

Making tonic water at home is dangerous!

Tonic water is primarily carbonated water and quinine. Quinine is most famous for treating the symptoms of malaria. Mixing gin and quinine dates to the British in various malaria prone climes where soldiers used gin to make the bitter quinine more palatable. In those days, quinine was extracted from cinchona bark in a process not unlike making tea. Since World War II, quinine has been manufactured as a white powder formed into pills. You can purchase quinine pills over the internet and dissolve them to use in tonic water. This is a bad idea. It would be very easy to poison yourself and guests with too much quinine. The recipes noted above and the ones you will find on the internet will use cinchona bark as the British did.  The problem is that you can’t know how much quinine is extracted from the cinchona bark.  Many people have developed cinchonism, the symptoms of quinine poisoning, from drinking DIY tonic water.  These symptoms include flushed and sweaty skin, ringing in the ears, abdominal pain, nausea, vomiting, diarrhea, headaches, rash, high pitched hearing loss and dizziness.  Larger doses can result in deafness, blindness, somnolence, shock, cardiac arrhythmias and death.  All of these symptoms will go away when the quinine is metabolized.  Well, except the death part.

These DIY tonic waters can be delicious. The problem is the quinine.  So why not leave out the cinchona bark and, thus, the quinine.  Make the syrup but, instead of adding carbonated water, add commercial tonic water!

Tonic Syrup and TinctureI had an opportunity to discuss Gin and Tonics with Jason Kosmas, Co-founder of The 86 Company, (Ford’s Gin among others), Co-founder of Employees Only and Co-author of Speak Easy. His take on tonic syrups is to include citrus, coriander and herbs – even herbal tea. Keep in mind that the base spirit you choose will lend itself to various flavors. As Jason pointed out – read the back label for flavor ideas. For syrup used in Rum and Tonics, he would add lime, pineapple, cinnamon and vanilla. (The rest of the interview centered on Gin Tonics and will be included in a future post)

Fever TreeqtonicThese days, you are not limited to buying tonic water in 1 liter bottles. There are a number of premium tonic waters available such as Fever Tree and Q Tonic. The primary idea of making your own tonic syrup is to customize it for various drinks. These recipes will take about 15 minutes of active and 45 minutes of inactive time.

The only equipment you will need that is slightly out of the ordinary is a digital food or postage scale. Only the precise weight of ingredients ensures that your syrup will be consistent from one batch to the next.
