What are the best brands of tonic water soda?

Quick answer

There is no single best tonic water, because taste is personal. Well-known brands include Schweppes, Fever-Tree and Q Mixers. What to check is the sweetener (sugar, corn syrup or agave), how dry or bitter it tastes, the quinine and whether you want a light or zero-sugar version. US tonic water may contain no more than 83 ppm quinine.

How do you choose a tonic water?

Tonic water is carbonated water with quinine, which gives it a bitter taste, plus sweetener and flavorings. It is mostly used as a mixer for gin and other spirits, but it also works alone over ice with citrus. Brands differ in sweetness, bitterness and carbonation, so there is no honest single best. Here is what to compare.

What is quinine and is there a limit?

Quinine is the bitter compound in tonic water. In the US, federal regulation (21 CFR 172.575) allows quinine as a flavor in carbonated beverages at no more than 83 parts per million, and the label must say it contains quinine, for example by including the word in the product name. If you have a medical condition, take certain medicines or are pregnant, ask a doctor whether quinine is suitable.

Well-known brands

Brands widely sold include:

  • Schweppes: a mainstream brand; US versions list ingredients such as high fructose corn syrup.
  • Fever-Tree: a premium brand, sweetened with sugar; the brand says its quinine comes from the Democratic Republic of Congo.
  • Q Mixers: listed by retailers as sweetened with organic agave.

This is not a ranking, and no verified quinine measurements per brand were found. Many tasting lists are opinion pieces.

What should you look at on the label?

Check Why
Sweetener Sugar, corn syrup, agave or sweetener affects taste and calories
Light or diet Fewer calories, different mouthfeel
Bottle size Small bottles keep the fizz in a single drink
Flavors Citrus, elderflower or botanical versions change cocktails

Tips

  • Chill it and pour gently to keep the bubbles.
  • Match the style: a dry tonic for a juniper-heavy gin, a sweeter one for mild spirits.
  • Do a side-by-side taste test with two brands.
  • Finish opened bottles within a few days.

What is the difference between regular and light tonic?

Light versions use less sugar or other sweeteners and have fewer calories. Taste and mouthfeel differ.

Which tonic water is best for gin?

It is a matter of taste. Try a dry tonic with strong gins and compare brands side by side.
