Bitter Lemon is a greenish-yellow, cloudy colored lemonade. To make Bitter Lemon, lime peels, carbonation and quinine have been added. Bitter lemon is a carbonated soft drink flavoured with quinine and lemon. The signature bitter taste is produced by a combination of the quinine and the lemon pith used in manufacturing the drink. The principal difference between tonic water and bitter lemon is the addition of lemon juice and rind. Bitter lemon is drunk both by itself, and as a mixer. It is sold across the world.
The generic bitter lemon drink dates back to 1834. Schweppes introduced its brand of bitter lemon in 1957.
