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.

The results for the best tonic water taste test
Comments: This has everything you want from a tonic water – sweet yet bitter with a well-rounded flavour profile and lemon notes. Try mixing this one with a vodka.
Comments: If you like your drinks a little sweeter, try this tonic with citrus notes. With a longer finish, this is ideal for a G&T.
Comments: A more complex tonic than the others we tasted, with distinct fruity, honey undertones. The grown-up flavour means it’d be lovely to drink on its own.
Comments: One of the more bitter tonics we tasted, this lemony one had a delicate sweetness and a slight dryness at the end.
