Country of Origin: Guatemala                             *FREE: DIY INSTRUCTIONS WITH PURCHASE

Only Bitters have ventured out to procure the best Cinchona Bark available anywhere in the world. We compared the less expensive product grown in China and India with that sourced from Central and South America and found the Central and South American product to be far superior, being both higher in alkaloids than the others, and not adulterated by being mixed in with other varietals. We then set out to find a sustainable and ethical producer (many suppliers steal bark from national forests or over-harvest), with practices that ensure the continued viability and health of their native trees. In addition, we wanted to find a producer supplying larger pieces of the bark, and not the smaller chips (so you can really see what you are getting).

Our high-quality Cinchona Succirubra (Red Cinchona) bark is grown in Guatemala. We source from a reputable sustainable farm that grows and harvests their own Cinchona trees. The bark sections from each tree are harvested once every 3 years for a term of 60 years.

Cinchona Succirubra is naturally high in Quinine Alkaloids. See table below for a difference between the cinchona varietals.

WARNING: Quinine Alkaloids could be toxic in high doses. Please do not exceed recommended dosages in parts per million when making your tonic syrup. As an example the US FDA and German authorities regulate that quinine be limited to between 83-85 parts per million (83-85 mg/L).


We have engaged a food scientist to determine conservative safe quantities for the use of this Cinchona Succirubra.

A little goes a long way!  Our recipe uses 64g of cinchona to produce approx 14 litres of tonic syrup or 70 litres of tonic water!

For orders with destinations outside of Australia, please check with your destination country regarding customs requirements for this item. Our bark is heat treated upon entering Australia.  If  in doubt, please order the powdered cinchona.  The powdered form is less likely to cause a problem as it is not whole bark, and it is packaged and vacuum sealed. 

New Zealand customers, please take particular note.  We have found that it is best to order the powdered cinchona.

Great product!

I wanted to make a tonic syrup for my friend's birthday. I did a cold extract of the bark, mixed with a slew of other aromatics and then a rich simple syrup - when I had a taste test, it was delicious! Great communication and easy pick up from the store front.

I have experimented with steeping the cinchona bark in a bottle of gin for about 3 weeks together with the zest of grapefruit. Just add soda water & ice and you have an insta G&T!


The promise of better gin and tonics

Just finished my first batch of tonic syrup and already have ideas of how to improve it.. but adjustments I will make are not bark related

Great product

It is what it says it is. Very easy to use and makes great tonic. I did get a few splinters breaking and chopping, but used gloves the second time and no issues.

Very happy
