Shoppers carrying one drink to lunch
A sealed 150ml can gives you a compact portion to take with you or keep at work. Tesco lists Fever-Tree Indian tonic in this size, while Sainsbury’s lists 150ml Schweppes tonic cans.
Who is a small tonic can for?
People comparing sugar and energy
Look at the per-100ml panel rather than treating “premium” or “light” as a nutrition figure. Tesco lists 15kcal and 3.8g sugars per 100ml for Fever-Tree Refreshingly Light Indian tonic, against 36kcal and 8.0g for its regular Indian tonic.
Shoppers choosing by flavour
If citrus and herbal ingredients influence your choice, read the product description as well as the pack size. Fentimans describes herbal infusions, Sicilian lemon oil and lemongrass in its Premium Indian Tonic Water; check the format of the product you plan to carry.
What should you check before choosing?
Start with the serving you need at lunch, then compare the label details that will affect what you drink.
| Priority | What to check | Your needs |
|---|---|---|
| Pack format | Check can volume and pack count. For a larger bottle, read its after-opening storage instructions. | I only want one portion away from home, without taking an opened bottle back with me. |
| Nutrition | Compare energy and sugars per 100ml on the same basis; then check the ingredients for sugar or named sweeteners. Tesco lists 36kcal and 8.0g sugars for regular Fever-Tree Indian tonic, and 15kcal and 3.8g for its Refreshingly Light version. | If I drink tonic on its own, I want to know what the portion contains rather than choosing by the word “light”. |
| Flavour | Read the stated citrus, herbal and flavouring ingredients. Fentimans describes Sicilian lemon oil and lemongrass in its Premium Indian tonic; decide whether you want that botanical direction or a more familiar Indian tonic. | Will I enjoy this chilled on its own at lunch, or am I keeping it to mix with another drink later? |
| Quinine | Check the ingredient list on the pack: tonic water is not plain sparkling water. If you have previously had an adverse reaction to quinine, seek appropriate clinical advice before choosing a quinine-containing drink. | I need to recognise quinine on the label, particularly if I have reacted to it before. |
What can catch you out?

Assuming premium means less sugar
Tesco’s regular and Refreshingly Light Fever-Tree Indian tonics have different declared per-100ml energy and sugar figures. The word “premium” does not tell you either value.
Compare the nutrition panels on the same per-100ml basis and read the sweetener ingredients if they matter to your choice.
-
Opening a large bottle for one lunch
A bottle may leave you with tonic to store after the meal. Sainsbury’s instructs buyers of its 1L Indian tonic to refrigerate it after opening and use it within 3 days.
For a single carried portion, check whether a sealed small can meets your needs instead.
A partly used bottle needs fridge space and prompt use under that product’s instructions.
-
Confusing tonic with plain sparkling water
The tonic products discussed here contain quinine. The Medicines and Healthcare products Regulatory Agency notes that adverse reactions can involve quinine found in tonic water and other drinks.
Read the current pack ingredients; if you have previously reacted to quinine, seek appropriate clinical advice before drinking tonic.
Which brand references are relevant?
Fever-Tree
Tesco lists regular and Refreshingly Light Indian tonic in 150ml cans, making the two formats straightforward to compare for a carried portion.
- The Tesco listings declare 36kcal and 8.0g sugars per 100ml for regular, versus 15kcal and 3.8g for Refreshingly Light.
- Both are tonics containing quinine; the lighter nutrition figures do not make an ingredient check unnecessary.
Schweppes
Sainsbury’s lists Schweppes Tonic Water in a 12 × 150ml can pack for shoppers seeking a compact, conventional tonic.
- Its listed ingredients identify quinine, sugar and sweetener.
- Check the particular variant’s ingredients rather than assuming all Schweppes tonics use the same formula.
Fentimans
Fentimans describes its Premium Indian Tonic Water using herbal infusions, Sicilian lemon oil and lemongrass extract.
- The stated ingredients give flavour-focused shoppers concrete details to consider.
- Check the pack volume before selecting it for one lunch away from home.
Britvic
Britvic’s 2023 announcement described 330ml Indian Tonic Water cans in classic and zero-sugar variants.
- The announced can size offers a format to consider if 150ml is not the portion you want.
- Check the current product label and pack details rather than treating a launch announcement as a description of every variant.
Tesco
Tesco lists own-label tonic options, including Finest Indian Tonic Water in a 500ml bottle, alongside branded formats.
- A bottle is worth considering when the drink will be shared or used on more than one occasion.
- Check whether its volume and after-opening instructions suit a single lunch away from home.
Sainsbury’s
Sainsbury’s lists own-label Indian and Diet Indian tonic in 1L bottles.
- The Diet Indian Tonic listing declares 2kcal and less than 0.5g sugars per 100ml for shoppers comparing labels.
- Its Indian Tonic Water bottle instructs users to refrigerate after opening and use within 3 days; check the label of the variant you buy.

Common questions
Is tonic water alcoholic on its own?
The Fever-Tree, Schweppes and Fentimans tonics discussed here are presented as soft drinks, not alcoholic drinks. You can drink tonic on its own; alcohol is introduced only if you mix it with an alcoholic drink.
How do I compare lighter tonics?
Compare the declared energy and sugars per 100ml, then read the ingredients for sweeteners. Tesco lists Fever-Tree Refreshingly Light Indian tonic at 15kcal and 3.8g sugars per 100ml; a different pack size or a “diet” label is not a substitute for checking that product’s panel.
Should I drink tonic water for leg cramps?
Do not use tonic water as a treatment for leg cramps. The Medicines and Healthcare products Regulatory Agency advises against routine quinine use for nocturnal leg cramps and highlights previous adverse reactions to quinine, including quinine found in tonic water. Seek medical advice about symptoms or a previous reaction.
What should I do with a larger tonic bottle after opening?
Follow that bottle’s storage label. Sainsbury’s instructs buyers of its 1L Indian Tonic Water to refrigerate it after opening and use it within 3 days; a sealed small can avoids storing a remainder when you only need one portion away from home.
