Fever-Tree is a producer of premium drink mixers, founded by Charles Rolls and Tim Warrillow in 2004.
The company’s name comes from its initial product which was a high quality tonic water. Their tonic was flavored with natural quinine, a chemical traditionally extracted from he bark of the South American chinchona tree. When introduced to India as a pharmaceutical to aid in reducing the fever associated with malaria , quinine was blended with soda and sugar to make it more palatable, producing the earliest tonic water. The chincona tree was referred to in India as fever tree.
Based in west London, Fever-Tree makes a variety of products, including tonic water, ginger beer and lemonade. As of March 2015, their products were exported to 50 countries.
