One-drink lunch packers
If you take one drink to work, a 150ml can can stay sealed until lunch. Joybuy lists both Schweppes Slimline and Fever-Tree Refreshingly Light Premium Indian Tonic Water in 150ml can multipacks.
Who might choose each format?
The useful distinction is whether you need one unopened portion to carry or can keep a larger bottle for another occasion.
Shoppers checking tonic ingredients
A light or slimline name does not tell you everything about the recipe. Joybuy lists Schweppes Slimline at 0g sugars and 2kcal per 100ml, with aspartame; its Fever-Tree Refreshingly Light Premium Indian Tonic Water listing gives 3.8g sugars and 15kcal per 100ml.
Office-fridge sharers
A larger bottle is worth considering if several people will use it or you have plans for the remaining drink. For Fentimans Ginger Beer 750ml, Sainsbury’s says to refrigerate the bottle after opening and consume it within three days.
What should you check before choosing?
Start with how you will carry and use the drink, then compare pack size, the exact recipe and the flavour you want.
| Priority | What to check | Your needs |
|---|---|---|
| Lunch portion | Check the volume of each portion and whether it is individually sealed. The Joybuy listings for Schweppes Slimline and Fever-Tree Refreshingly Light Premium Indian Tonic Water specify 150ml cans; a larger bottle needs a plan once opened. | I want to put one unopened drink in my lunch bag, rather than bring a partly used bottle home. |
| Pack size | Count the portions you expect to use. Joybuy lists 12 cans in the Schweppes Slimline pack and 15 in the Fever-Tree Refreshingly Light Premium Indian Tonic Water pack; check other packs individually before assuming the same format. | If I bring a drink on several workdays, I want enough separate portions without leaving an opened bottle in the fridge. |
| Ingredients | Read sugars and energy per 100ml alongside the ingredient list. Joybuy lists 0g sugars and 2kcal per 100ml for Schweppes Slimline, which contains aspartame and a source of phenylalanine; its Fever-Tree Refreshingly Light Premium Indian Tonic Water listing gives 3.8g sugars and 15kcal per 100ml. | I check the exact tonic recipe when sugars or a particular sweetener matter to me; the words ‘light’ and ‘slimline’ are not substitutes for the label. |
| Flavour and storage | Decide whether you want tonic or ginger beer, and read the storage instructions for the exact bottle. Fever-Tree describes quinine as contributing tonic’s bitterness; Sainsbury’s says to refrigerate Fentimans Ginger Beer 750ml after opening and consume it within three days. | For a drink at lunch, flavour matters. If I choose a larger bottle, I also need somewhere to keep what remains. |
Packed-lunch mixer pitfalls
-
Taking a large bottle for one lunch without a storage plan
A bottle may leave you with an opened drink after lunch. Sainsbury’s instructions for Fentimans Ginger Beer 750ml say to refrigerate it after opening and consume it within three days.
Choose a larger bottle when you can store and use the remainder as directed; otherwise, consider an individually sealed portion.
-
Assuming every light tonic is sugar-free
Joybuy lists 3.8g sugars per 100ml for Fever-Tree Refreshingly Light Premium Indian Tonic Water, compared with 0g sugars per 100ml for Schweppes Slimline. Those figures describe these specific products, not every tonic bearing either name.
Compare the current nutrition panels for the exact flavours and pack sizes you are considering.
-
Overlooking the sweetener declaration
Joybuy’s Schweppes Slimline listing names aspartame and states that the drink contains a source of phenylalanine. A sugars figure alone will not show whether a recipe contains that ingredient.
If you need to avoid aspartame or check phenylalanine, read the label of the exact product before use.
Brand and product-line references
These examples show how formats and recipes differ; a brand name alone does not establish the details of every mixer in its range.
Schweppes
Joybuy lists Schweppes Slimline Tonic Water in a 12 × 150ml can pack, a format for taking one sealed portion to lunch.
- The listed Slimline recipe has 0g sugars and 2kcal per 100ml.
- This product contains aspartame and a source of phenylalanine; check its current label if either matters to you.
Fever-Tree
Joybuy lists Fever-Tree Refreshingly Light Premium Indian Tonic Water in a 15 × 150ml can pack. Fever-Tree describes quinine as contributing tonic’s bitterness.
- The listed pack provides individually portioned cans.
- Joybuy lists 3.8g sugars per 100ml for this light tonic; do not read ‘light’ as ‘sugar-free’.
Fentimans
Fentimans Ginger Beer 750ml is a bottled alternative to an individually portioned tonic pack.
- The 750ml format can be considered when the drink will be shared or used on more than one occasion.
- Sainsbury’s says to refrigerate this bottle after opening and consume it within three days.
Britvic
Britvic Limited announced 330ml six-packs of classic and zero-sugar Indian tonic water in 2023.
- Britvic describes each 330ml can as providing two serves, a different portioning arrangement from one 150ml can.
- If you want just one drink at lunch, decide what you would do with the rest of an opened can.
Tesco
Tesco Groceries lists 1L own-label Indian tonic water, including a low-calorie version, as a larger-bottle route.
- A 1L bottle gives you a format to consider for sharing or repeat use.
- It does not provide separate sealed lunch portions; check the exact bottle’s storage directions if you plan to use it over several days.

Common questions
Are 150ml cans more practical than a large bottle for one office lunch?
A sealed 150ml can is simpler to pack when you want one portion and have no plan for leftovers. A larger bottle can suit sharing or repeat use, provided you can follow its storage instructions: Sainsbury’s says to refrigerate Fentimans Ginger Beer 750ml after opening and consume it within three days.
Does ‘light’ tonic mean sugar-free?
No—not for every product. Joybuy lists 3.8g sugars per 100ml for Fever-Tree Refreshingly Light Premium Indian Tonic Water, while its Schweppes Slimline listing gives 0g sugars per 100ml and names aspartame. Compare the current labels of the exact products.
What gives tonic water its bitter taste?
Fever-Tree identifies quinine as an ingredient contributing tonic’s bitterness. If that flavour is unfamiliar, trying a smaller quantity before choosing a multipack lets you decide whether you enjoy it.
Which ingredient declarations should I check on a mixer?
Check the current ingredient list for anything you need to avoid, as well as the nutrition panel if sugars matter to you. Joybuy’s Schweppes Slimline listing, for example, names aspartame and states that the drink contains a source of phenylalanine; do not assume another tonic has the same recipe.
