Lower-sugar tonic drinkers
If you want tonic’s bitter flavour, the distinction between no-sugar slimline tonic and light tonic with sugar matters more than the wording on the front of the pack.
Who is choosing a takeaway mixer?
Shoppers avoiding sweeteners
If you want to avoid both sugar and sweeteners, consider plain soda water rather than assuming a diet tonic meets both requirements.
Takeaway hosts planning different serves
If drinks may be served with or without spirits, decide on the mixer and any alcohol separately. Check the amount poured when comparing the mixer’s nutrition information.
What matters when choosing a mixer?
Start with the flavour you want, then compare nutrition information on the same per-100ml basis. The NHS explains that food labels give nutrition information per 100ml and sometimes per portion.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars and energy | Compare sugars, carbohydrate and energy per 100ml on the exact pack. Fentimans lists 0g sugar and 0 kcal per 100ml for its Soda Water, but 3.4g sugars and 18 kcal per 100ml for its Naturally Light Tonic. | I want to know whether I am choosing a no-sugar mixer or a light tonic that still contains sugar. |
| Flavour and sweetener | Choose between plain soda water and tonic’s quinine-led flavour, then read the ingredients and warnings. Sainsbury’s lists aspartame and a phenylalanine warning for Schweppes Slimline; the NHS says aspartame is unsuitable for people with PKU. | Tonic bitterness matters to me, but I also need to know which sweetener is in the drink. |
| Amount poured | Use the per-100ml figures to work out the sugars and energy in the amount you plan to pour. Check whether a pack also gives figures per portion. | When sharing drinks over a takeaway, I want the comparison to reflect what goes into each glass. |
| Alcohol in the serve | Decide whether to add a spirit and how much. A mixer’s sugar information does not describe alcohol intake; the UK Chief Medical Officers’ guidance addresses alcohol-related risk. | I may serve the mixer on its own, or with a spirit, and do not want to confuse a lower-sugar mixer with an alcohol-free drink. |
Which mixer-label mistakes should you avoid?
-
Treating “light” and “no sugar” as the same thing
The labels describe different choices. Fentimans lists 0g sugar per 100ml for Soda Water and 3.4g sugars per 100ml for Naturally Light Tonic.
Compare sugars and energy per 100ml on the exact pack, then account for the amount you will pour.
-
Choosing slimline tonic without reading its ingredients
Sainsbury’s lists aspartame and a source-of-phenylalanine warning for Schweppes Slimline. The NHS says aspartame is unsuitable for people with PKU.
Check the ingredients and warning on the tonic you intend to buy. If you require a mixer without sweeteners, consider plain soda water.
-
Letting the mixer label stand in for an alcohol decision
A no-sugar mixer does not change how much alcohol is added to a spirit-and-mixer drink.
Decide whether the serve will contain alcohol. If it will, consider the amount of spirit separately; the UK Chief Medical Officers’ guidance addresses alcohol-related risk.
What do the brand ranges offer?
These product lines illustrate why it is worth checking the exact variety, rather than relying on a brand name or a “light” description.
Schweppes
Slimline Tonic Water is a no-sugar tonic option for shoppers who still want tonic flavour.
- Sainsbury’s lists under 0.1g sugars and 2 kcal per 100ml for Schweppes Slimline Tonic Water.
- It contains aspartame and carries a phenylalanine warning. The NHS says aspartame is unsuitable for people with PKU.
Fever-Tree
Refreshingly Light Indian Tonic is a reduced-calorie tonic, not a substitute for checking whether a drink contains sugar.
- Fever-Tree says this tonic has 50% fewer calories than its Premium Indian Tonic.
- Its ingredients include fructose. Check the sugars figure on the pack if a no-sugar mixer is your requirement.
Fentimans
Its Soda Water, Naturally Light Tonic and Premium Indian Tonic give shoppers distinct choices to compare.
- Fentimans lists 0g sugar and 0 kcal per 100ml for Soda Water.
- Its Naturally Light Tonic lists 3.4g sugars and 18 kcal per 100ml; Premium Indian Tonic lists 4.4g sugars and 20 kcal per 100ml. Neither tonic is a no-sugar choice.

Questions about diet and light mixers
Is light tonic the same as no-sugar tonic?
No. Fentimans lists 3.4g sugars per 100ml for Naturally Light Tonic, while Fever-Tree lists fructose in its Refreshingly Light Indian Tonic. Compare the sugars figure per 100ml on the exact pack rather than using “light” as a no-sugar claim.
What can I choose if I want neither sugar nor sweetener?
Plain soda water is an option if you do not need tonic bitterness. Fentimans lists 0g sugar and 0 kcal per 100ml for its Soda Water; check the ingredients of whichever soda water you choose.
Can I choose slimline tonic if I avoid aspartame?
Not without checking the particular tonic’s ingredients. Sainsbury’s lists aspartame and a phenylalanine warning for Schweppes Slimline. The NHS says aspartame is unsuitable for people with PKU.
Does a lower-sugar mixer change the risk from alcohol?
No. The mixer’s sugar content does not determine the amount of alcohol in a drink. Decide whether to add a spirit and how much separately; the UK Chief Medical Officers’ guidance addresses alcohol-related risk.
