Fever-Tree Mediterranean is made by blending the essential oils from herbs gathered from around the Mediterranean shores with highest-quality quinine from the ‘fever trees’ of the Democratic Republic of the Congo, creating a delicate, floral tonic water. It’s used less quinine in the Mediterranean Tonic which, with the addition of rosemary and lemon thyme, produces a much lighter, more fragrant tonic. We start with the idea that, if ¾ of your drink is the mixer, then you should use the best. We work with only the best naturally sourced ingredients from around the world and no artificial flavourings or sweeteners to create mixers that do justice to the world’s finest spirits.
