Fever-Tree is a premium natural mixer brand that creates its drinks from only the finest natural ingredients. The founders, Tim and Charles have spent years trekking the globe seeking out unique, natural ingredients from independent farms and plantations. Their ingredient hunting led them to the Rwanda Congo border to the last quinine plantation in the Congo which produces the best quality quinine in the world. This quinine is blended with spring water and 8 botanical flavours, including rare ingredients such as marigold extracts and a bitter orange from Tanzania to produce the distinct taste of our tonic water. Fever-Tree have gone on to develop 9 more drinks from this. The award winning natural mixers taste clean, subtle and balanced, all with authentic flavours.
