Hosts serving a larger gathering
If several guests are likely to choose the same mixer, estimate the total volume before choosing bottles or cans. Check whether an opened bottle can be used within its stated storage period.
Who is this for?
Hosts planning a few specific mixed drinks
Individual cans can help you plan portions for particular serves without opening a large bottle for just one drink. Check that the can size and flavour suit the drinks you intend to make.
Shoppers checking ingredients
Compare the exact product labels if sugars, calories or sweeteners matter to your guests. Slimline and standard tonic are not interchangeable descriptions of the same formulation.
What should you check?
Start with the drinks menu and likely number of serves, then check pack format, ingredients and storage instructions for the mixers you would actually use.
| Priority | What to check | Your needs |
|---|---|---|
| Quantity | Check total pack volume, serving size and how many drinks need each mixer. The Waitrose & Partners 1-litre own-label tonic listing states four 250ml servings. | I expect several guests to choose the same tonic and want enough for those planned drinks. |
| Portions | Compare shareable bottles with individual cans. The Waitrose & Partners Fever-Tree Indian Tonic listing contains eight 150ml cans; Fever-Tree suggests 150ml of mixer with a 50ml spirit serve. | Only a few guests want a particular pairing, so individual portions may suit my drinks plan better. |
| Ingredients | Read sugars and energy per 100ml alongside the ingredient list. The Waitrose & Partners listing for Schweppes Slimline Indian Tonic Water with Lemon Zest states 0g sugars and 2kcal per 100ml and lists aspartame. | I want to check what is in each tonic rather than assume that slimline and standard versions have the same ingredients. |
| Flavour | Choose a flavour for a planned drink rather than assuming every mixer will suit every serve. Fentimans describes herbal infusions, Sicilian lemon oil and lemongrass in its Indian tonic; its Victorian Lemonade listing includes lemon juice and fermented ginger-root extract. | A botanical tonic or lemonade appeals for a particular pairing or alcohol-free drink, but I also need a mixer for more general use. |
| Storage | Read the instructions for the exact bottle. The Waitrose & Partners listings for its own-label tonic and Fentimans Victorian Lemonade say to refrigerate after opening and consume within three days. | If I am unlikely to finish an opened bottle within its stated period, I would rather plan smaller portions. |
Shopping pitfalls
-
Counting packs without checking their volume
A bottle and a multipack of cans can provide different numbers and sizes of serves, even when both look sufficient for a gathering.
Work out the mixer volume for the drinks you plan to serve, then compare it with the volume in each pack.
-
Treating slimline, light and standard tonic as the same recipe
The Waitrose & Partners listings identify aspartame in Schweppes Slimline Indian Tonic Water with Lemon Zest and 8.0g sugars per 100ml in standard Fever-Tree Indian Tonic Water. Those details apply to the named products, not every version of either brand.
Compare the nutrition panel and ingredients on each exact variant, including any sweetener declaration.
-
Choosing speciality flavours without a drinks plan
A distinctive tonic or lemonade may have fewer planned uses than a mixer several guests will drink. Opened bottles may also have a short refrigerated-use instruction.
List the intended pairings and alcohol-free serves before deciding how many flavoured bottles or cans to buy.
-
Using an online description for a guest’s ingredient check
The physical pack gives the information for the drink being served. This matters when a guest needs to check an allergen or particular ingredient.
Read that pack’s ingredients and relevant warnings before serving, rather than relying only on the shopping-page description.

Frequently asked questions
How much mixer should I buy for Christmas?
Start with the number and size of drinks you intend to serve, then add up the mixer volume they require. Fever-Tree suggests 150ml of mixer for one 50ml spirit serve, while the Waitrose & Partners own-label 1-litre tonic listing states four 250ml servings; allow separately for guests drinking a mixer on its own.
Should I buy a large bottle or individual cans?
A large bottle can suit repeated serves of the same mixer; cans make individual portions easier to plan when fewer drinks need that mixer. Check the exact bottle’s instructions: the Waitrose & Partners own-label tonic listing says to refrigerate after opening and consume within three days.
What should I check on a slimline tonic label?
Check sugars and energy per 100ml, ingredients and sweetener warnings for the exact variant. The Waitrose & Partners listing for Schweppes Slimline Indian Tonic Water with Lemon Zest states 0g sugars and 2kcal per 100ml, but also lists aspartame and a phenylalanine warning.
Which pack details matter when serving guests with ingredient requirements?
Read the physical pack’s ingredients, allergen information and relevant warnings before serving. GOV.UK’s food-labelling guidance describes ingredient and allergen information for pre-packed food and drink; checking the pack also lets you assess the particular drink you have bought.
