COLA DRINKS are one of America's great inventions.
In the late-19th century they were claimed to cure impotence and indigestion.
Virtually all colas are sugared fizzy water flavoured with cinnamon, vanilla and citrus oils.
All colas were tasted blind by two 10-year-olds and two adults. Calories given are per 100ml.
