Fever-Tree Premium Lemonade is made using natural lemon juice. The drink is sweetened using only natural cane sugar. Importantly, no preservatives or artificial ingredients are ever used in any of Fever-Tree's products. If three quarters of your drink is the mixer, then you should be using the best mixers. 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.
