Fever Tree Aromatic Tonic Water is made using naturally sourced quinine from the bark of the fever tree in the Congo, blended with spring water, natural cane sugar and Tanzanian bitter orange, much like their Premium Indian Tonic Water. The Aromatic Tonic adds the gentle bitterness of South American angostura bark and aromatic cardamom, pimento and ginger. This tonic is designed to enhance robust and juniper-rich gins. Importantly, no preservatives or artificial ingredients are ever used in any of Fever-Tree's products. If three quarters of your Gin & Tonic is tonic, then you should be using the best tonic. This is the attitude Fever-Tree brought to the craft of their original Indian Tonic Water and a standard they continue to apply across their range.
