What Is Tonic Water? 

Tonic water is a carbonated water that has quinine in it, which creates a sharp bittersweet flavor. You may recognize brand names like Canada Dry or Schweppes, though there are many more tonic water distributors out there.

Most of the traditional tonic waters on the market have been sweetened so that the bitterness from the quinine has a more balanced flavor.

Tonic water was actually originally created as a kind of medicine for British soldiers in India. In order to mask the bitter flavor of the quinine, officers would mix it with soda and sugar, and thus, tonic water was born!

There are a lot of tonic waters out there that are loaded with sugars. While you wouldn’t expect sugar to be a high part of something that has “water” in the title, you should beware that many of them have a lot of sugar.
