Quinine. 11/15/2015

 I am shooting for 30mg, as a  daily dose to help control spasticity  in Multiple Sclerosis, as recommend by my Neurologist.


What is going on here is an acidic extraction. Quinine is an alkaloid, which is an alkaline compound derived from a plant. This reacts with an acid, in our case citric acid. A salt is formed, quinine citrate, which dissolves easily in water

The recipie below should get me close

Content Comparison by Cinchona species

Species Total Alkaloids (%) Quinine Content (%)
C. calisaya 3 - 7    0 - 4
C. pubescens 4.5 - 8.5.   1 - 3
  Used this.  C. officinalis 5 - 8    2 - 7.5
C. ledgeriana 5 -14    3 - 13
C. succirubra 6 - 16    4 - 14
So ask which varietal you are getting. The above is just a guide. Hope it is useful.

So knowing which varietal you are getting helps in knowing which are stronger etc.

The Most Popular Tonic Water Syrup Recipe Has Too Much Quinine

Let's take one of the most popular tonic syrup recipes, published by Jeffrey Morgenthaler: Basically, it's 6 cups of liquid to 1/4 cup of powdered cinchona bark, which is about 35 grams of cinchona. Extrapolate from that and we're talking about 35 grams of cinchona per 1.4 liters of end syrup, which is 25 grams per liter, and if it extracts fully, contributes 1.25 grams of quinine per liter, which equates to 1251 parts per million. That's 15 times the CFR standard.

If you use 3/4 of an ounce of that syrup in a Gin and Tonic, you're adding in 27.5 mg of quinine - more than double the amount of quinine in a commercial gin and tonic


Used 4 cup water, 10 allspice berries.   Made 3/4 liter bottle.
Simmered just over 20 minutes. 3/4 oz serving took. Brown murkey color. Left unfiltered.


  • 4 cups water
  • 1 cup chopped lemongrass (roughly one large stalk)
  • ¼ cup powdered cinchona bark
  • zest and juice of 1 orange
  • zest and juice of 1 lemon
  • zest and juice of 1 lime
  • 1 tsp whole allspice berries
  • ¼ cup citric acid
  • ¼ tsp Kosher salt
  1. Combine ingredients in a medium saucepan and bring to a boil over high heat.
  2. Once mixture starts to boil, reduce heat to low, cover and simmer for 20 minutes.
  3. Remove from heat and strain out solids using a strainer or chinois.
  4. You'll need to fine-strain the mixture, as it still contains quite a bit of the cinchona bark.
  5. You can use a coffee filter and wait for an hour or more, or do as I do and run the whole mixture through a French coffee press.
  6. Once you're satisfied with the clarity of your mix, heat it back up on the stovetop or microwave, and then add ¾ cup of agave syrup to each cup of your hot mix.
  7. Stir until combined, and store in the attractive bottle of your choice.
  8. You now have a syrup that you can carbonate with seltzer water; I use my iSi soda siphon for some nicely-textured bubbles.
  9. To assemble a gin and tonic, use ¾ ounce of syrup, 1½ ounces of gin and 2 ounces of soda water over ice.

There's a federal standard for the use of quinine in carbonated beverages, specifically that it cannot exceed 83 parts per million in the final tonic water (21 CFR 172.575). Now, if you're working with commercial quinine sulphate or quinine hydrochloride, it's easy to calculate. Basically, that ends up being 2.48 mg of commercial quinine per ounce of tonic water.

So, let's expand this out: a typical gin and tonic is 1.5 oz of gin and 4.5 oz of tonic, 6 ounces total. That means we can expect 11.16mg of quinine in that beverage.

However, most producers of tonic syrups don't use quinine hydrochloride/quinine sulphate... and there's the rub.

Cinchona bark is approximately 5% quinine.

Let's take one of the most popular tonic syrup recipes, published by Jeffrey Morgenthaler: Basically, it's 6 cups of liquid to 1/4 cup of powdered cinchona bark, which is about 35 grams of cinchona. Extrapolate from that and we're talking about 35 grams of cinchona per 1.4 liters of end syrup, which is 25 grams per liter, and if it extracts fully, contributes 1.25 grams of quinine per liter, which equates to 1251 parts per million. That's 15 times the CFR standard.

If you use 3/4 of an ounce of that syrup in a Gin and Tonic, you're adding in 27.5 mg of quinine - more than double the amount of quinine in a commercial gin and tonic. 

Note: Does a syrup extract quinine fully from the cinchona? No - but it extracts faster from powdered cinchona versus cinchona chips or quills.

Note: Does a syrup that is sieved through a french press or a coffee filter have a high percentage of solids still in suspension? Yes - and any of the solids you swallow contribute the full amount of the quinine as your body digests the powder.
