For a strict no-added-sugars preference, start with plain soda water whose ingredients contain nothing used to sweeten it; the ingredient lists published by Fentimans and Coca-Cola Great Britain make their respective soda waters useful examples. At a second home, choose a pack size you expect to finish during a visit and follow that product’s instructions after opening. Sugar-free tonic is an alternative if you want tonic flavour, but check its ingredients separately for sweeteners and quinine.
If you may leave before finishing an opened bottle, compare individual cans or small bottles with larger packs. Check the exact product’s storage instructions before deciding how much to open during a stay.
Read the ingredients as well as the sugars figure in the nutrition panel. A light, slimline or sugar-free name does not, by itself, answer whether sugars or other foods used for sweetening were added.
Soda water and tonic are different choices. If tonic flavour matters, check the tonic’s ingredients for sugar, sweeteners and quinine rather than treating plain soda water as a like-for-like substitute.
Choose when: Avoiding added sugars matters more than having tonic flavour; Fentimans and Schweppes list unsweetened soda-water ingredients.
Trade-off: It does not provide tonic’s quinine bitterness or added flavour.
Choose when: You want tonic character without sugar in the nutrition panel and have checked the particular product’s ingredients.
Trade-off: Sugar-free tonic can contain sweeteners and quinine; the front-of-pack description alone does not settle a separate no-added-sugars preference.
Choose when: You prefer a particular light tonic and your requirement is not to avoid added sugars.
Trade-off: Fever-Tree Refreshingly Light Indian Tonic lists fructose, while Fentimans Naturally Light Tonic lists sugar.
| Priority | What to check | Your needs |
|---|---|---|
| Added sugars | Read the ingredient list for added sugars or other foods used for sweetening. Check sugars per 100ml in the nutrition panel too; a zero figure alone does not describe every ingredient. | I want a mixer that meets my no-added-sugars preference, not simply one labelled light or slimline. |
| Pack size and storage | Compare the amount you will open with the servings you expect to use. Follow the particular pack’s instructions once opened; Waitrose & Partners instructs buyers of its Sugar Free Mediterranean Tonic Water to refrigerate it and consume it within 3 days. | At an occasionally used property, I would rather open one small pack than leave a partly used bottle behind. |
| Tonic flavour | Decide whether plain soda water will do or whether you want tonic. For tonic, inspect the ingredients for sugar, sweeteners and quinine rather than relying on a light or sugar-free name. | I still want tonic in my drink, so plain soda water may not give me the flavour I am looking for. |
| Quinine | Look for quinine on the exact tonic’s ingredient list. Waitrose & Partners lists quinine hydrochloride in its Sugar Free Mediterranean Tonic Water; the published Fentimans and Schweppes soda-water ingredient lists do not include it. | If quinine matters to someone using the property, I need to check the mixer separately from its sugar content. |
Fever-Tree Refreshingly Light Indian Tonic lists fructose, Fentimans Naturally Light Tonic lists sugar, and Waitrose & Partners’ sugar-free Mediterranean tonic lists sucralose. Those descriptions answer different questions about a drink.
Read the current ingredients and nutrition panel against your actual requirement. If you also wish to avoid sweeteners, check for them separately.
An opened bottle may have a product-specific deadline for use. Waitrose & Partners instructs buyers of its Sugar Free Mediterranean Tonic Water to refrigerate it after opening and consume it within 3 days.
Estimate how many servings you will use before leaving, then compare that with the pack size and its own storage wording.
Waitrose & Partners lists quinine hydrochloride in a sugar-free tonic. Sugar content does not tell you whether a tonic contains quinine.
Check the ingredient list if quinine is a concern for anyone at the property; consider plain soda water if tonic flavour is unnecessary.
These examples illustrate different label and pack-size checks; a brand name alone does not establish the ingredients of every product in its range.
Fentimans lists its Soda Water in a 200ml format, with carbonated water, salt and sodium bicarbonate as ingredients and 0g sugar per 100ml.
Coca-Cola Great Britain lists carbonated water and sodium bicarbonate for Schweppes Soda Water, with 0g sugars per 100ml.
Fever-Tree Refreshingly Light Indian Tonic Water is a tonic option, but its manufacturer’s ingredient list includes fructose.
Britvic announced 330ml Indian Tonic Water cans in classic and zero-sugar variants in September 2023.
Tesco Groceries lists its Low Calorie Indian Tonic Water in a 6 × 250ml format alongside other mixer ranges.
These individually canned options are for households considering tonic or a soft drink as a mixer during occasional visits. Check their current labels if avoiding added sugars is the deciding requirement; neither product title establishes it.

The individual 150ml cans may suit a visit when you want to open one tonic at a time. Check the current can for sweeteners and quinine, and do not treat slimline as proof of a no-added-sugars formulation.

Consider this canned soft drink if you want an alternative to tonic as a mixer and expect to use a 24-can pack across visits. Each can is 330ml; check the current ingredients if sweeteners or a strict no-added-sugars preference matter to you.
No. The no-added-sugars claim condition published by legislation.gov.uk concerns added mono- or disaccharides and other foods used for sweetening; a sugar-free description does not answer that ingredient question on its own. For example, Waitrose & Partners lists sucralose in its Sugar Free Mediterranean Tonic Water, so check separately if you also want to avoid sweeteners.
Choose a size you expect to finish while you are there, then follow that product’s storage instructions. Waitrose & Partners tells buyers of its Sugar Free Mediterranean Tonic Water to refrigerate it after opening and consume it within 3 days; do not assume the same instruction applies to every mixer.
Not on the strength of the word light. Fever-Tree lists fructose in Refreshingly Light Indian Tonic Water, and Fentimans lists sugar in Naturally Light Tonic Water. Check the ingredients of the particular tonic before choosing it for a no-added-sugars requirement.
Yes. Waitrose & Partners lists quinine hydrochloride in its Sugar Free Mediterranean Tonic Water. If quinine matters to your household, read the exact product’s ingredients; the published ingredient lists for Fentimans and Schweppes soda water do not include it.
