Natural Ingredients Made with natural quinine from the Loja province in Ecuador. Why from Loja? In 1639, the Countess of Chinchona was cured of a fever thanks to an infusion made from the bark of the cinchona tree from the region of Loja, and as such this remedy became popular for the treatment of fever and malaria among the people of this humble town. It was so effective that it was even used to heal various kings of Europe, such as Louis XIV of France and Charles II of England. Lemongrass. Le Tribute tonic water contains a distillation of lemongrass in water, which provides its unique flavour. The purest water. The water is sourced from a natural spring belonging to the distillery, and is filtered via a reverse osmosis process until it becomes demineralised and flavourless. Production Process Fizz. With the aim of achieving a strong and long-lasting fizz, the latest technology is used to chill the liquid to 2ºC, in order to produce a Gin & Tonic with the perfect level of fizziness and freshness from beginning to end. The bottle. It is the first square-shaped bottle on the market for a carbonated beverage: the latest industrial design techniques allowed Le Tribute to bottle the tonic water into square-shaped bottles. A unique bottle that is able to bear high pressure.
