What is tonic water?

Tonic water is a carbonated soft drink with a distinctly bitter flavour that is usually used as a mixer. Natural quinine is sometimes added to give the bitter taste, while some brands add sugar for sweetness.


How the best tonic water taste test worked

Four members of the olive team conducted a blind taste test to find the best original tonic water, awarding gold and silver to the ones we were most impressed with.
