Hosts who need a no-added-sugar tonic
Look for the exact claim on the current bottle rather than relying on ‘light’, ‘low calorie’ or ‘slimline’. Read the ingredients too: a no-added-sugar tonic can still contain sweeteners.
Who is choosing a mixer?
Hosts serving different sweetness preferences
An explicitly labelled no-added-sugar tonic and a separate plain soda water give guests a choice between sweetened tonic flavour and an unsweetened mixer.
Shoppers comparing light and standard tonic
Fever-Tree lists fructose in its Refreshingly Light Indian Tonic Water and sugar in its regular Premium Indian Tonic Water. Compare the particular bottles rather than treating ‘light’ as a no-added-sugar claim.
What should you check before buying?
Choose the type of mixer your guests want, then check the claim, ingredients and pack format on the product you plan to serve.
No-added-sugar tonic
Choose when: The exact no-added-sugar claim matters and guests want tonic rather than plain soda water.
Bear in mind: M&S and SPAR list sweeteners in their no-added-sugar tonics, and SPAR says its product is not stocked in every store.
Plain soda water
Choose when: Guests want an unsweetened mixer; Coca-Cola Great Britain lists carbonated water and sodium bicarbonate as the ingredients in Schweppes Soda Water.
Bear in mind: Soda water does not give a drink the sweetened flavour of tonic.
Light tonic
Choose when: A lighter tonic is the preference and a no-added-sugar claim is not required.
Bear in mind: Fever-Tree lists fructose in its Refreshingly Light Indian Tonic Water, so do not substitute it for an explicitly labelled no-added-sugar tonic.
| Priority | What to check | Your needs |
|---|---|---|
| No-added-sugar claim | Look for the exact claim on the current pack. Read the ingredient list for sugar or fructose; ‘light’ and ‘low calorie’ describe different considerations. | I want a tonic explicitly labelled no added sugar, not simply one described as lighter. |
| Sweeteners | Compare the named sweeteners on each tonic. M&S lists sucralose; SPAR lists aspartame and sodium saccharin. Check any relevant aspartame wording on the pack. | Some guests prefer an unsweetened mixer, so I want plain soda water available separately from sweetened tonic. |
| Serving format | Check bottle or can size, where you can buy it and the pack’s instructions after opening. M&S advises refrigerating its opened tonic and consuming it within three days. | For a BBQ, I would rather open drinks as they are needed than leave several large bottles open. |
Common mixer-shopping mistakes
-
Treating ‘light’ and ‘no added sugar’ as the same claim
Fever-Tree lists fructose in its Refreshingly Light Indian Tonic Water. Its lighter description therefore does not meet a shopping requirement for an explicit no-added-sugar claim.
Check that the current pack says ‘No Added Sugar’, then read its ingredients and nutrition information.
-
Assuming no-added-sugar tonic is unsweetened
M&S lists sucralose in its Diet Indian Tonic Water, while SPAR lists aspartame and sodium saccharin in its Low Calorie Indian Tonic Water. Guests may have different ingredient preferences.
Read each tonic’s ingredient list and offer plain soda water as a separate unsweetened choice.
-
Opening every large bottle at the start of the BBQ
M&S advises refrigerating its tonic after opening and consuming it within three days. SPAR also says its tonic may not be stocked in every store.
Check local availability before settling on a drinks list, and open bottles as they are needed.
Opening more M&S tonic than you can serve within its stated period could leave some unused.

Schweppes Slimline Tonic Water, 12 × 150ml

Mixer questions answered
Does ‘light’ tonic mean no added sugar?
No. Fever-Tree lists fructose in its Refreshingly Light Indian Tonic Water and sugar in its regular Premium Indian Tonic Water. If no added sugar is the requirement, look for that exact claim on the tonic you buy.
Can a no-added-sugar tonic contain sweeteners?
Yes. M&S Diet Indian Tonic Water lists sucralose, while SPAR Low Calorie Indian Tonic Water lists aspartame and sodium saccharin. Check the individual ingredients if a guest has a sweetener preference.
What should I check on a tonic containing aspartame?
Check the ingredient list and pack warning. GOV.UK’s food-labelling guidance gives the wording ‘Contains a source of phenylalanine’ or ‘Contains aspartame (a source of phenylalanine)’ for products containing aspartame.
How should I handle an opened 1L tonic bottle?
Follow the instructions on the particular bottle. M&S advises refrigerating its Diet Indian Tonic Water after opening and consuming it within three days, so open bottles as the BBQ needs them rather than all at once.
