One mixer per drink
If you make drinks separately during a gaming or snack session, a 150ml multipack lets you open one container without measuring from a large bottle. Tesco Groceries and Sainsbury’s list tonic multipacks in this format.
Who might prefer small mixers
Individual containers are most useful when you want to open a mixer for one drink at a time; the recipe still matters as much as the pack size.
Shoppers comparing sugar and sweeteners
Look at the exact variant rather than relying on words such as “light”. Sainsbury’s lists Schweppes Slimline as having no sugar and carrying a phenylalanine-source warning, while its Fever-Tree Refreshingly Light listing describes a different recipe that contains sugar.
Flavour-led spirit mixers
If botanical ingredients matter more to you than an individual 150ml container, Fentimans describes quinine and botanicals in its tonic range. Check the pack size of the particular product before treating it as a mini-mixer option.
What to check before choosing
Start with the amount you expect to pour per drink, then compare the nutrition and ingredient labels of the exact tonic you would buy.
| Priority | What to check | Your needs |
|---|---|---|
| Serving format | Check the volume per container and the number in the pack. UK listings include 12 × 150ml Schweppes and 15 × 150ml Fever-Tree tonics; Britvic described its 330ml can at its September 2023 launch as two serves. | I would rather open one small mixer for a drink than leave a litre bottle open between rounds. If I plan to share or pour more than one drink, a larger container may suit that use instead. |
| Sugar and sweeteners | Compare sugars using the same basis, such as per 100ml or per serving, and read the ingredients. Sainsbury’s lists no sugar for Schweppes Slimline 12 × 150ml; its Fever-Tree Refreshingly Light 15 × 150ml listing gives 3.8g sugars per 100ml. | If I want a no-sugar tonic, a “light” name alone does not settle the choice. I also want to know which sweeteners the exact variant contains. |
| Tonic flavour | Check whether you want a standard Indian tonic or a botanical-led variant. Fentimans names juniper, kaffir lime leaves and lemongrass in its Premium Indian Tonic Water; that description does not establish how it will taste with every spirit. | For a drink mixed with gin or another spirit, I may care more about the tonic’s ingredients than about getting the smallest container. |
| Pack label | Read the current ingredients and warnings on the exact pack. Sainsbury’s Schweppes Slimline listing carries a phenylalanine-source warning; check the container type too if cans and bottles are not interchangeable for your plans. | I need to check ingredients relevant to me before drinking, rather than relying only on the pack’s front label or an older retailer description. |
Common mistakes with mini mixers
-
Reading “light” as “no sugar”
Sainsbury’s lists 3.8g sugars per 100ml for Fever-Tree Refreshingly Light 15 × 150ml, so its light positioning does not answer a no-sugar requirement.
Compare the sugars line for the exact variant, using its stated per-100ml or per-serving basis.
-
Counting a 330ml can as one mini serve
Britvic described its 330ml Indian Tonic can as providing two serves when it announced the format in September 2023. It is a different portioning choice from a 150ml container.
If you want one unopened container per drink, check for a 150ml pack; consider 330ml when you expect to split or pour more than one serve.
-
Overlooking sweeteners in a no-sugar tonic
Schweppes Slimline is listed without sugar, but its Sainsbury’s listing also identifies aspartame and carries a phenylalanine-source warning.
Read the ingredients and warnings alongside the nutrition panel.
-
Using a retailer description instead of the current pack
The ingredients or labelling of the container you receive may differ from a description you read earlier.
Check the current pack before drinking, particularly when an ingredient or allergen matters to you.
Mixer brands and formats
These brand examples show different pack sizes and recipes; a brand’s inclusion here does not mean every product in its range comes in a mini format.
Schweppes
Sainsbury’s lists standard and Slimline tonic in 12 × 150ml packs.
- The 150ml containers suit one mixer pour at a time.
- The recipes differ: Sainsbury’s lists 7.4g sugars per 150ml for its standard tonic, while its Slimline listing says no sugar and carries a phenylalanine-source warning.
Fever-Tree
UK grocery listings include Fever-Tree tonic in 150ml multipacks.
- Sainsbury’s lists Refreshingly Light tonic as a 15 × 150ml pack.
- That listing gives 3.8g sugars per 100ml. Fever-Tree’s statement that it has 50% fewer calories compares it with the brand’s Premium Indian Tonic Water; it does not mean no sugar.
Fentimans
Fentimans describes tonic recipes built around quinine and botanicals.
- Its Premium Indian Tonic Water description names juniper berries, kaffir lime leaves and lemongrass.
- Check the size and container of the product you choose if an individual mini serve is essential.
Britvic
Britvic announced six-packs of 330ml Indian Tonic cans in September 2023.
- Britvic described each 330ml can as providing two serves.
- It is not the same portion size as a 150ml container; check the current product listing before planning around that pack.
Tesco
Tesco’s own-label mixer listings include soda water and low-calorie Indian tonic in 6 × 250ml packs.
- The 250ml format offers individual containers for a larger pour.
- Check whether 250ml fits your drink; it is not a 150ml mini serve.
Sainsbury’s
Sainsbury’s lists own-label Indian Tonic Water and Diet Indian Tonic Water in 1L bottles.
- A 1L bottle can serve several pours when drinks are being shared.
- It does not provide a separate unopened container for each drink.

No image available
Fever-Tree Refreshingly Light Premium Indian Tonic Water 15 × 150ml
Fifteen 150ml portions allow separate mixer pours across a session. Sainsbury’s listing for this variant gives 3.8g sugars per 100ml, so the light name should not be read as a no-sugar claim.

Fever-Tree Indian Tonic Water 8 × 150ml
This eight-pack provides 150ml portions for drinks made separately. Choose between this Indian tonic and the other named variants by checking their current ingredients and nutrition labels, rather than treating the pack size as a recipe comparison.
No image available
Schweppes Indian Tonic Water 12 × 150ml
Twelve 150ml portions suit individual mixer pours. Check the current nutrition and ingredients label if comparing it with Schweppes Slimline, and confirm whether the container is a can or bottle if that distinction matters to you.
Questions about mini mixers
What size works as an individual mini mixer?
For one separate mixer pour, start by looking at 150ml containers: UK listings include Schweppes 12 × 150ml and Fever-Tree 150ml multipacks. Britvic described its 330ml Indian Tonic can as two serves at its September 2023 launch, so that size answers a different portioning need.
Which 150ml tonic option has no sugar?
Sainsbury’s lists Schweppes Slimline Tonic Water 12 × 150ml as having no sugar. Its listing also identifies aspartame and carries a phenylalanine-source warning, so read the current pack if those ingredients matter to you.
Does “Refreshingly Light” mean sugar-free?
No. Sainsbury’s lists 3.8g sugars per 100ml for Fever-Tree Refreshingly Light tonic. Fever-Tree’s fewer-calories statement compares the product with its own Premium Indian Tonic Water, not with a no-sugar recipe.
What should I check if an ingredient or allergen matters to me?
Read the current ingredients, allergen information and warnings for the exact pack before drinking it. In particular, Sainsbury’s Schweppes Slimline listing carries a phenylalanine-source warning; do not use a no-sugar description as a substitute for checking the label.
Can I drink tonic without adding a spirit?
Yes. The Schweppes product descriptions discussed here present tonic as a drink that can be served on its own or used as a mixer. The 150ml pack-size decision still applies if you want to open one portion at a time.
