Repeat multipack buyers
If you use mixers regularly, check the number and size of servings rather than assuming that two multipacks contain the same volume.
Who might choose each format?
Shoppers taking one drink at a time
An individual 150ml can avoids carrying a partly used bottle. If you choose a larger bottle, check how it must be stored after opening.
Shoppers checking sugar and sweeteners
Compare the nutrition and ingredient labels for the exact tonic variant. Slimline and diet products can contain different sweeteners.
What should you check before buying?
Start with how many portions you will use and where you will drink them. Then check the exact variant’s ingredients and storage instructions.
| Priority | What to check | Your needs |
|---|---|---|
| Pack quantity | Check the serving size, pack count and total volume. Twelve 150ml servings contain 1.8 litres; eight contain 1.2 litres. | I use several portions during the week and want to choose a pack size I can finish. |
| Taking a drink out | Check whether the pack contains individual cans or a larger bottle. Sainsbury’s says its 1L Diet Indian Tonic Water with Lemon must be refrigerated after opening and used within three days. | On rushed mornings, I would rather take one unopened portion than manage a partly used bottle. |
| Ingredients | Read sugars per 100ml and the ingredient list for the exact variant. Joybuy’s Schweppes Slimline listing names aspartame and carries a phenylalanine warning. | I want to know which sweetener a drink contains instead of relying on a word such as “slimline”. |
| Breakfast | Decide whether you need a drink alongside food or simply something to drink. The NHS Eatwell Guide describes a balanced diet through a range of food groups, not a fizzy drink alone. | If I need breakfast, I will plan food as well as a drink; if I only want a drink, water is another option. |
Common buying mistakes
-
Treating a mixer as breakfast
A fizzy drink does not take the place of the range of foods described in the NHS Eatwell Guide.
If you need breakfast, choose food first and treat the mixer as an optional drink alongside it.
-
Assuming “slimline” means unsweetened
Lower-sugar variants can contain sweeteners. Joybuy’s Schweppes Slimline listing names aspartame and carries a phenylalanine warning.
Read the ingredients and nutrition information for the particular flavour and pack you are buying.
-
Choosing a large bottle without a storage plan
Sainsbury’s instructs buyers of its 1L Diet Indian Tonic Water with Lemon to refrigerate it after opening and use it within three days.
If you normally take just one drink away from home, consider individual portions; choose the bottle when you can follow its storage instructions.
Brands and retailers to consider
Schweppes
Schweppes appears in the cited listings with 12 × 150ml tonic and soda-water packs.
- The small servings suit taking one drink at a time.
- Check the variant: Joybuy’s Slimline Tonic lists aspartame and a phenylalanine warning.
Fever-Tree
Fever-Tree lists tonic, soda and ginger drinks among its mixer ranges.
- Its cited Indian Tonic listing comes in an eight-pack of 150ml servings.
- The listed Indian Tonic contains sugar; do not use the brand name as a guide to a variant’s nutrition.
Fentimans
Fentimans lists Indian tonic, naturally light tonic, ginger ale and soda water in its mixer range.
- The range offers several flavours to consider if tonic is not the only mixer you want.
- Check the format and ingredients of the particular product rather than assuming every drink in the range is alike.
Britvic
Britvic’s portfolio includes mixers and The London Essence Company.
- In a May 2025 announcement, Britvic described London Essence lemonade in six 150ml cans and crafted sodas in four 250ml cans.
- Those formats contain different numbers and sizes of servings, so check which product meets your routine.
Tesco
Tesco’s tonic-and-mixers category lists standard, slimline and other options in different pack sizes.
- The category makes it possible to compare serving counts and pack volumes in one place.
- Check the exact variant and pack size; they can differ even within the same brand.
Sainsbury’s
Sainsbury’s lists a 1L own-label Diet Indian Tonic Water with Lemon as a bottle alternative to small-can packs.
- A single bottle may suit planned servings at home.
- Sainsbury’s says to refrigerate this tonic after opening and use it within three days.
Original tonic multipack comparison
This composite list compares individually portioned tonic packs on its original unit-volume basis. Its positions do not assess flavour, nutrition or whether a mixer is suitable as breakfast.
| Rank | SKU name | Main specifications | Reasons to consider | Platform |
|---|---|---|---|---|
| 1 | Schweppes Slimline Tonic Water 12 × 150ml | Twelve 150ml servings. | For portioned tonic use; Joybuy’s listing names aspartame and carries a phenylalanine warning. | Joybuy |
| 2 | Schweppes Indian Tonic Water 12 × 150ml | Twelve 150ml servings. | For shoppers considering standard Indian tonic; check the container format before choosing it for travel. | Joybuy |
| 3 | Fever-Tree Indian Tonic Water 8 × 150ml | Eight 150ml servings; 8.0g sugars per 100ml on Joybuy’s product page. | A smaller portioned pack; check its sugar information against the exact drink you want. | Joybuy |

Schweppes Slimline Tonic Water 12 × 150ml
A 12 × 150ml tonic pack for taking one portion at a time. Joybuy’s product information lists aspartame and states that it contains a source of phenylalanine; check the label if those ingredients matter to you.
Image unavailable
Schweppes Indian Tonic Water 12 × 150ml
This standard Indian tonic comes in twelve 150ml portions. If you need cans for travel, confirm the container type before buying; the product information describes the format inconsistently.
Image unavailable
Fever-Tree Indian Tonic Water 8 × 150ml
Eight 150ml cans offer individual mixer portions. Joybuy’s product page lists 8.0g sugars per 100ml, so check the nutrition label if sugar content affects your choice.
Image unavailable
Fever-Tree Naturally Light Tonic Water 8 × 150ml
An eight-pack of 150ml tonic portions for shoppers considering the Naturally Light variant. “Light” does not mean sugar-free; check its nutrition and ingredient label against your preferences.

Canada Dry Ginger Ale Mini 12 × 150ml
Twelve 150ml mini cans offer single portions of a ginger-ale mixer. Check the pack’s nutrition label if you are comparing energy information, as the product descriptions give conflicting figures.
Questions about morning mixers
Can a mixer replace breakfast when I am in a hurry?
A mixer is a drink, not a replacement for the range of foods described in the NHS Eatwell Guide. If you need breakfast, plan food alongside your drink; if you simply want something to drink, water is another option.
How do I compare multipacks with different numbers of cans?
Check both the can size and pack count. Eight 150ml portions contain 1.2 litres, while twelve contain 1.8 litres; then consider how many individual drinks you will use.
Are small cans more practical than a 1L bottle for taking out?
Small cans suit taking one unopened portion at a time. A bottle can suit planned use at home, but follow its particular storage instructions: Sainsbury’s says to refrigerate its 1L Diet Indian Tonic Water with Lemon after opening and use it within three days.
Does “slimline” mean a tonic contains no sweeteners?
No. Read the exact product label: Joybuy’s Schweppes Slimline Tonic listing names aspartame and carries a phenylalanine warning. Other diet tonic variants can use different sweeteners.
