Quinine is the key ingredient that creates the gentle bitterness in tonic water. Our name was chosen as it is the colloquial name for the cinchona tree, the bark of which produces quinine. After discovering early 17th century references in the British library, Charles and Tim located one of the only remaining plantations of original Cinchona Ledgeriana trees (known locally as ‘fever trees’) which produce some of the highest quality quinine in the world, located in the Democratic Republic of Congo. For Charles and Tim, there was no other option but to source Fever-Tree’s quinine from this area.

To capture the finest elderflower flavour, we source handpicked flowers from the English countryside. We ensure our elderflowers are hand-collected from the highest quality elder bushes in the UK in the late Spring when the elderflowers are in full bloom. The flowers are picked when they are at their freshest before the petals are distilled into an oil.
