For young children, do not make fizzy tonic the after-school drink: NHS guidance says fizzy drinks should not be given to babies and young children, while University Hospitals Sussex NHS Foundation Trust identifies water or plain milk as the safest between-meal drinks for children at raised risk of tooth decay. If the cans are for adults in the household, choose between zero-sugar, reduced-calorie and standard tonic by checking the exact product’s sugar and sweetener information as well as its pack size.
Who is this choice for?
Parents choosing an after-school drink
If the drink is for a young child, keep tonic cans out of the routine snack choice. NHS guidance advises against fizzy drinks for babies and young children; University Hospitals Sussex NHS Foundation Trust identifies water or plain milk as the safest drinks between meals for children at raised risk of tooth decay.
Adults sharing the snack cupboard
A multipack of 150ml tonic cans can be kept for adult serves without opening a larger bottle. Keep it separate from drinks chosen for children, and compare the pack count, flavour and label of the exact tonic.
Adults comparing sugar and sweeteners
Joybuy lists 0g sugars per 100ml for Schweppes Slimline, which contains aspartame and a source of phenylalanine. Its listed Fever-Tree Refreshingly Light variants contain sugars, so their names should not be read as meaning sugar-free.
What should you check before buying?
Decide who will drink the cans before comparing adult tonic labels; a smaller can does not turn a mixer into a routine child-snack drink.

What to check |
Your needs |
| Intended drinker |
For young children, follow NHS advice not to give fizzy drinks. For children at raised risk of tooth decay, University Hospitals Sussex NHS Foundation Trust identifies water or plain milk as the safest between-meal drinks. |
I’m choosing a drink to go with a child’s snack, rather than stocking an adult mixer. |
| Sugar level |
Read sugars per 100ml on the exact pack. Joybuy lists 0g for Schweppes Slimline, 3.8g and 4.2g for the two named Fever-Tree Refreshingly Light tonics, and 8.0g for Fever-Tree Indian Tonic Water. |
For an adult serve, I want to distinguish zero sugar from a lighter-labelled tonic that still contains sugar. |
| Pack format |
Check the number of cans and their volume: 12 × 150ml is 1.8 litres in total; 15 × 150ml is 2.25 litres. Check storage instructions for the exact product. |
We use tonic occasionally, so individually sized cans may suit us better than opening a large bottle. |
| Ingredients and flavour |
Check the tonic style and ingredient list. Joybuy’s Schweppes Slimline listing states that it contains aspartame and a source of phenylalanine; Fever-Tree’s light variants have different listed sugar values. |
I’d like an adult mixer with a flavour and ingredient list that suits the person drinking it. |
Mistakes to avoid
-
Treating a tonic can as a child’s snack drink
Being sold as a soft drink does not make fizzy tonic the routine choice for a young child. NHS guidance advises against fizzy drinks for babies and young children.
Keep adult mixer cans separate from children’s drinks. For children at raised risk of tooth decay, University Hospitals Sussex NHS Foundation Trust identifies water or plain milk as the safest between-meal options.
-
Reading “light” as sugar-free
Joybuy lists 3.8g sugars per 100ml for Fever-Tree Refreshingly Light Premium Indian and 4.2g for its Refreshingly Light Mediterranean tonic; Schweppes Slimline lists 0g.
Compare the per-100ml nutrition panels on the exact packs rather than choosing by the front-of-pack name alone.
-
Overlooking the sweetener label
Joybuy’s Schweppes Slimline listing names aspartame and states that the drink contains a source of phenylalanine.
If either ingredient matters to the intended adult drinker, check the current product label before choosing the multipack.
-
Comparing can counts without checking volume
Pack count alone does not show how much tonic you are buying: 12 × 150ml totals 1.8 litres, while 15 × 150ml totals 2.25 litres.
Compare total volume alongside the sugar information, ingredients and number of individual serves your household expects to use.
Relevant mixer brands and alternatives
These brand references cover different tonic formats and product lines; they are not all confirmed canned-multipack choices.
Fever-Tree
Its named Joybuy tonic packs include standard Indian and Refreshingly Light varieties in 150ml servings.
- The listed Refreshingly Light Premium Indian and Mediterranean products contain 3.8g and 4.2g sugars per 100ml respectively.
- Neither is sugar-free. Fever-Tree says its mixers contain no artificial sweeteners or flavourings; check the exact pack when that distinction matters.
Schweppes
The named Slimline and standard Indian Tonic Water products are listed as 12 × 150ml packs on Joybuy.
- Joybuy lists 0g sugars per 100ml for the Slimline product.
- Slimline contains aspartame and a source of phenylalanine. Do not apply its nutrition values to the standard Indian tonic.
Fentimans
Fentimans lists Premium Indian and Naturally Light tonic varieties, including a 4 × 200ml Naturally Light format.
- Fentimans lists 4.4g sugars per 100ml for its Premium Indian Tonic Water.
- Check the container type on a current listing if a multipack of cans is essential; the stated 4 × 200ml format alone does not establish it.
Tesco
Tesco Groceries lists own-label regular and low-calorie Indian tonic in 1-litre bottles.
- The bottle formats provide an option to consider if individual cans are not needed.
- Check the format of any Tesco product before treating it as a canned-multipack alternative.
Britvic
Britvic describes itself through a portfolio of soft-drink brands rather than a single Britvic-labelled tonic range.
- Its portfolio is relevant when identifying the company behind a listed drink brand.
- Check the actual drink brand, container and pack details instead of assuming a Britvic-labelled tonic multipack.

Frequently asked questions
Are tonic cans suitable as an after-school drink for young children?
Do not make them the routine choice for young children. NHS guidance says fizzy drinks should not be given to babies and young children; University Hospitals Sussex NHS Foundation Trust identifies water or plain milk as the safest between-meal drinks for children at raised risk of tooth decay. The named tonic products are better considered separately as adult mixers.
Is Schweppes Slimline Tonic Water sugar-free?
Joybuy lists 0g sugars per 100ml for its Schweppes Slimline Tonic Water 12 × 150ml pack. Its ingredient information also names aspartame and states that it contains a source of phenylalanine, so read the exact label if those ingredients matter to the intended drinker.
Does Fever-Tree Refreshingly Light tonic contain sugar?
Yes, the named Joybuy products do: Refreshingly Light Premium Indian lists 3.8g sugars per 100ml, and Refreshingly Light Mediterranean lists 4.2g per 100ml. Neither should be treated as a zero-sugar tonic.
How do 12-can and 15-can tonic packs compare?
At 150ml per can, a 12-can pack totals 1.8 litres and a 15-can pack totals 2.25 litres. Choose the count that fits expected adult use, then compare the exact products’ nutrition, ingredients and flavour rather than treating can count as the only difference.
