Hosts serving a mixed group
If guests may want different mixers, plan the total volume without assuming everyone will choose the same flavour. Shared bottles can cover drinks made from a common selection.
Who is buying?
Hosts planning self-service drinks
Individual 150ml cans let guests open a portion when they make a drink. A 12 × 150ml pack contains 12 cans and 1.8 litres altogether.
Hosts checking sugar and sweeteners
A separately labelled tonic gives guests another choice. Schweppes Slimline contains aspartame, so check its ingredient label when that matters to someone attending.
What matters when choosing mixers?
Start with the amount you expect to serve, then decide whether shared bottles or separate cans fit the way guests will make their drinks.
| Priority | What to check | Your needs |
|---|---|---|
| Party volume | Multiply the can size by the pack count: 12 × 150ml is 1.8 litres; 8 × 150ml is 1.2 litres. Count any shared bottles separately. | I want enough mixer for the drinks planned, rather than judging a multipack by its can count alone. |
| Serving format | Check whether the pack contains individual 150ml cans or a shared 1L bottle. Consider where guests will make their drinks. | Separate cans would make self-service simpler; shared bottles work if pouring from one place suits the party. |
| Ingredients | Read the sugar information per 100ml and the ingredient list on the exact variant. Check sweeteners separately from any “light” or “Slimline” wording. | I would like guests to be able to identify an alternative tonic without assuming that different variants contain the same ingredients. |
| Flavour choice | Distinguish Indian tonic and soda from botanical, fruit-flavoured and ginger mixers. Match any additional flavour to the drinks you plan to serve. | If guests prefer different drinks, I can offer a familiar tonic or soda alongside a deliberately chosen flavoured option. |
What is easy to overlook?

Buying only one tonic style for a mixed group
Indian tonic, soda, Slimline tonic and botanical or fruit-flavoured mixers are distinct choices. A flavoured tonic will not suit every planned drink or preference.
Start with a tonic or soda that fits the main drinks menu, then add a clearly labelled alternative or a specific flavour where it has a purpose.
Brand ranges to consider
These references describe relevant mixer ranges, not which brands or variants are available in the product selection below.
Tesco
Tesco Groceries lists own-label tonic in 1L bottles.
- A shared-bottle format to consider when guests will pour from the same mixer.
- A 1L bottle does not provide individually sealed portions.
Sainsbury's
The reviewed Sainsbury's range included own-label 1L tonic alongside branded cans.
- The bottle format provides another way to plan shared serves.
- Check the exact variety if guests want separate standard and diet options.
Schweppes
Standard and Slimline tonic are available as distinct 12 × 150ml can packs in the reviewed Sainsbury's listing.
- Each pack provides 12 separately portioned cans, totalling 1.8 litres.
- Schweppes Slimline contains aspartame; read the label rather than treating it as interchangeable with standard tonic.
Fever-Tree
Fever-Tree presents a range of tonic styles for hosts planning particular flavours.
- The brand's tonic range includes Indian and flavoured variants.
- Check the specific variant and pack size; one tonic style does not stand in for the whole range.
Fentimans
Fentimans describes its mixer range as botanical and offers several flavour directions.
- The brand lists tonic and ginger options for different drinks menus.
- Choose a flavour for a planned drink rather than assuming it will replace a standard tonic for every guest.
Individual-can options on Joybuy
These tonic multipacks represent the individual-can route for a garden party. Compare their pack sizes and variants with your serving plan; shared-bottle choices are a separate decision.

Schweppes Slimline Tonic Water 12 × 150ml
Twelve individual 150ml cans provide 1.8 litres for separately made drinks. This is the Slimline variant; its listed ingredients include aspartame, so check the label if a guest needs to account for it.

Schweppes Indian Tonic Water 12 × 150ml
Twelve individual 150ml cans provide 1.8 litres when guests will make separate drinks. Choose this Indian tonic variant rather than Slimline when it fits the planned drinks and guests' preferences.

Fever-Tree Refreshingly Light Premium Indian Tonic Water 15 × 150ml
Fifteen individual 150ml cans total 2.25 litres, a format to consider when the party calls for more separate tonic serves. “Light” is part of this variant's name, not a reason to assume it contains no sugar; check the label.
No image available
Fever-Tree Refreshingly Light Mediterranean Tonic Water 8 × 150ml
Eight individual 150ml cans total 1.2 litres. The Mediterranean variant makes sense as a deliberate flavour choice for planned drinks, rather than an assumed replacement for Indian tonic or soda.
No image available
Fever-Tree Naturally Light Tonic Water 8 × 150ml
Eight individual 150ml cans provide 1.2 litres of this light-style tonic. Check its nutrition and ingredient label if guests are choosing between it and a no-sugar variant.
Common questions
How much mixer is in a 150ml-can multipack?
A 12-can pack contains 1.8 litres, an eight-can pack 1.2 litres and a 15-can pack 2.25 litres. Match the total and the number of separate cans to the drinks you plan to make.
Is Schweppes Slimline a no-sugar tonic choice?
The reviewed product information describes Schweppes Slimline as low-calorie and lists 0g sugars per 100ml. It also lists aspartame, so check the label if its ingredients matter to a guest.
Should I buy flavoured tonic for everyone?
Not necessarily. Choose a flavoured tonic when it fits drinks you intend to serve, and keep an Indian tonic or soda option if guests may prefer a different mixer.
