What is tonic syrup?

Made to a recipe formulated in the 1820s, the sin-kō-nah tonic syrup is infused with cinchona bark – the natural source of quinine.  This is the defining ingredient of tonic water. Using the bark imparts a uniquely bitter flavour and distinctive colour to the syrup.

Other ingredients used are juniper berries, and local citrus – the zest and juice of lemons, limes and oranges for that piquant zing.


Tonic syrup was originally concocted by officers serving in British India to ease fever and ward off malaria. Mixed with soda and gin, this highball cocktail became an icon of the colonial Empire.


Quinine is a chemical that naturally occurs in cinchona bark. It is an anti-malarial, and muscle relaxant. It has been used at various times to treat stress, heartburn, upset tummies, leg cramps … and gin.

What makes sin-kō-nah tonic syrup special? IMG_6223

The tonic syrup is made with real cinchona bark (not extract, not powder), the natural source of quinine. That’s where the name sin-kō-nah comes from.

The bark is imported and infuse it into the tonic syrup, just as they did in British India back in the 1820s.

Medicinal uses

Quinine has long been used as a treatment for malaria. However, it has also been used to treat gastric disorders, flu, cramps, fever and general aches and pains. 

We love the bitterness of cinchona bark

While cinchona may indeed offer these health benefits and more, the main reasons Tonic syrup use the bark is for its authenticity and inimitable flavour profile. Quite frankly,  it makes their tonic syrup taste damn good, with or without gin! The colour it imparts also makes for a pretty drink.

Our ingredients

The cinchona bark is imported. Due to biosecurity issues, neither the seeds nor plants can be brought into Australia, but it can be imported in its milled state.

Tonic Syrup source as many of its ingredients as possible locally. The citrus used is sourced from local farmers. Handcrafting the tonic, producing it in small batches, using no additives or preservatives also make sin-kō-nah tonic syrup special.
