For four people making the same mojito-style drink, a 4 x 150ml cocktail-mixer pack matches Fever-Tree’s stated recipe of one can per drink, according to the Sainsbury’s product listing. If guests want tonic with a choice of spirits, a 4 x 200ml Fentimans bottle pack listed by Real Foods offers 800ml instead; choose a larger tonic multipack if you expect more serves, and check the total volume rather than the pack count alone.
Who is each format for?
Hosts making four mojitos
A 4 x 150ml Fever-Tree Mojito Mixer pack suits a group planning the same drink. The recipe on Sainsbury’s listing uses one 150ml can with 50ml rum per drink; rum and the other serving ingredients need to be planned separately.
Groups choosing tonic-based drinks
Tonic leaves room to choose a spirit rather than committing everyone to a mojito mixer. Fever-Tree describes its Premium Indian Tonic as intended for gin, vodka and fortified wines; Fentimans describes its Connoisseurs Tonic as a botanical tonic. Check the particular tonic’s flavour before choosing it for the group.
Hosts weighing portions against leftovers
Individual 150ml cans, 200ml bottles and larger bottles call for different serving plans. For its 1-litre Indian Tonic, Tesco instructs shoppers to refrigerate an opened bottle and consume it within three days.
What should you check before buying?
Decide which drinks you are making, then compare the pack’s total volume with the number of serves you expect. Check nutrition and ingredients on the current pack if they matter to your guests.
| Priority | What to check | Your needs |
| Pack volume |
Multiply the unit count by the container size: 4 x 150ml is 600ml, 4 x 200ml is 800ml, and 4 x 1 litre is 4 litres. Compare that total with the recipe’s mixer portion. |
I’m making only a few drinks and want to know whether a four-pack means four portions or a much larger supply. |
| Drink and flavour |
Check whether the product is a cocktail-specific mixer or tonic. Sainsbury’s lists Fever-Tree Mojito Mixer with a rum-based recipe; Fever-Tree positions Premium Indian Tonic for gin, vodka and fortified wines. |
If guests have settled on mojitos, I can choose the matching mixer. If they want different tonic-based drinks, I need a tonic flavour that suits the planned serves. |
| Nutrition and ingredients |
Compare sugars and energy on the same per-100ml or per-serving basis. Check sweeteners and any relevant warnings on the specific product label. |
I want guests to be able to check the ingredients and nutrition of the mixer they are actually drinking, rather than assume every tonic has the same formulation. |
| Storage |
Read the opened-container instructions. Tesco says its 1-litre Indian Tonic should be refrigerated after opening and consumed within three days. |
A large bottle works for me only if we expect to use it and can follow its storage instructions afterwards. |
Common mixer-buying mistakes
-
Treating every four-pack as four equal serves
Four 150ml cans contain 600ml, while four 1-litre bottles contain 4 litres. The same pack count can therefore mean very different amounts of mixer and potential leftovers.
Check the volume of each container and the mixer amount in your intended recipe before deciding how many packs to buy.
-
Choosing a mojito mixer for a tonic-based drinks table
Fever-Tree’s Mojito Mixer is a lime-and-mint cocktail mixer with a stated rum-based recipe. It does not serve the same flavour role as tonic.
Settle the drinks menu first: choose the cocktail mixer for mojito-style serves, or select a suitable tonic if guests want tonic-based drinks.
-
Assuming standard and lower-calorie tonics have the same ingredients
Recipes differ between products. Britvic’s Low Calorie Indian Tonic lists aspartame and saccharin and carries a phenylalanine warning, according to Britvic.
Compare the specific packs’ nutrition and ingredient panels using the same serving size or per-100ml figures, and check any warnings relevant to guests.
-
Serving from an older online listing
Ingredients and nutrition information can change, while larger bottles can have instructions for use after opening.
Read the current pack before serving, particularly for ingredients, allergen information and storage directions.
Brands and ranges to compare
These examples show how the format and intended drink can differ within the mixer category; check the exact product rather than choosing by brand alone.
Fever-Tree
Its range includes tonic and a separate 4 x 150ml Mojito Mixer format.
- Fever-Tree positions Premium Indian Tonic for gin, vodka and fortified wines.
- The Mojito Mixer has a specific lime-and-mint cocktail use; it is not a substitute for tonic when guests want tonic-based drinks.
Fentimans
Real Foods lists Fentimans Tonic Water in a 4 x 200ml bottle pack.
- Fentimans lists quinine, fermented juniper, kaffir lime and lemongrass extracts for its Connoisseurs Tonic.
- The listed four-unit tonic pack is bottles, not 150ml cans; do not assume every Fentimans tonic has the same ingredients or pack size.
Schweppes
The range includes standard Indian Tonic and Slimline options.
- ASDA lists standard Schweppes Indian Tonic in an 8 x 150ml can pack, with 7.4g sugars per 150ml serving.
- That eight-can listing does not establish a four-can pack; check the size and ingredients of the variant you choose.
Britvic
Britvic lists Indian Tonic and Low Calorie Indian Tonic in its mixer range.
- The two formulations give shoppers different ingredient panels to compare.
- Britvic’s Low Calorie Indian Tonic lists aspartame and saccharin and carries a phenylalanine warning; check the current pack before serving.
Tesco
Tesco lists an own-label Indian Tonic pack containing four 1-litre bottles.
- The 4-litre total is a distinct option when the plan calls for substantially more mixer than four small individual containers provide.
- Tesco instructs shoppers to refrigerate each bottle after opening and consume it within three days.
Joybuy tonic multipacks
These are 8- and 12-can tonic options for a brunch where extra portions may be useful. They are not four-unit cocktail-mixer or four-bottle tonic packs.

Schweppes Slimline Tonic Water 12 x 150ml
A tonic option when the group may want more than four individual cans. The pack contains twelve 150ml cans, so it is larger than the four-unit format in the brunch question; check the current label for ingredients relevant to guests.

Fever-Tree Refreshingly Light Mediterranean Tonic Water 8 x 150ml

Fever-Tree Naturally Light Tonic Water 8 x 150ml
This Indian tonic is an eight-can option if the brunch plan allows for extra individual portions. Each can is 150ml; use the current pack label when comparing nutrition and ingredients with another tonic.

Fever-Tree Indian Tonic Water 8 x 150ml
An Indian tonic option for guests planning tonic-based drinks. The eight 150ml cans exceed a four-can plan, so decide whether the additional portions will be used.

Questions about brunch mixers
Does a four-pack always make four drinks?
No. Four containers can hold very different total volumes. Sainsbury’s lists a 4 x 150ml Fever-Tree Mojito Mixer pack and a recipe using one can per drink, while Real Foods lists a 4 x 200ml Fentimans tonic pack containing 800ml in total. Work out the number of drinks from the recipe you intend to serve.
Should I choose tonic or a cocktail mixer for brunch?
Choose a cocktail-specific mixer when everyone wants that drink and you have its other ingredients. Fever-Tree’s Mojito Mixer has a stated rum-based recipe; tonic is the option to consider when guests instead want tonic-based drinks, with Fever-Tree positioning its Premium Indian Tonic for gin, vodka and fortified wines.
What should I compare on standard and lower-calorie tonic labels?
Compare nutrition on the same per-100ml or per-serving basis, then read the ingredients and warnings for each exact product. ASDA lists 7.4g sugars per 150ml for standard Schweppes Indian Tonic; Britvic lists aspartame and saccharin and a phenylalanine warning for its Low Calorie Indian Tonic. Those details describe different products, not every tonic in either range.
What should I do with tonic left in a large bottle?
Follow the storage directions on that bottle. Tesco’s 1-litre Indian Tonic listing instructs shoppers to refrigerate it after opening and consume it within three days. If the group expects only a few serves, factor possible leftovers into the pack-size decision.
