Hosts serving several similar drinks
Count the likely mixer portions before choosing a pack. Separate 150ml units make portions straightforward; a larger bottle makes more sense when the group will use it after opening.
Who is choosing the mixers?
Hosts serving different sugar preferences
Check whether guests want regular tonic, a lower-calorie option or one listing no sugars. The nutrition panel and sweeteners on the exact pack matter more than the word “light”.
Small groups mixing different drinks
When guests are making gin, vodka or alcohol-free serves, consider whether a classic, citrus or botanical tonic fits the drinks planned. A smaller pack may also be easier to use up.
What should you check?
Settle the drinks and likely number of serves first, then compare formats and read the exact product labels.
| Priority | What to check | Your needs |
|---|---|---|
| Portions and storage | Check the unit count and volume: 12 × 150ml provides 12 separate portions, while a 1L bottle is shared. Read the opened-bottle storage instructions. | I’m serving several drinks and want a separate mixer for each, or I know the group will use an opened bottle promptly. |
| Sugars and sweeteners | Compare sugars per 100ml and the ingredients. The Joybuy Schweppes Slimline 12 × 150ml listing states 0g sugars per 100ml and names aspartame and a source of phenylalanine; Fever-Tree Refreshingly Light Premium Indian 15 × 150ml lists 3.8g sugars per 100ml. | Some guests prefer regular tonic; others want a no-sugar or lower-calorie option. I need to distinguish those choices rather than assume they mean the same thing. |
| Flavour | Check whether the tonic is classic Indian, Mediterranean or botanical, and consider its stated ingredients alongside the drinks planned. | I’m making different brunch drinks and don’t want one strongly flavoured tonic to stand in for every serve. |
| Ingredients | Read the ingredient and allergen information on the purchased pack, particularly when a guest avoids a sweetener or has an allergy. Product formulations can change. | Before serving a guest with a specific dietary need, I want to check the actual label rather than rely on the brand name. |
Common buying mistakes
-
Treating “light” and “slimline” as interchangeable
Fever-Tree Refreshingly Light Premium Indian lists 3.8g sugars per 100ml. Schweppes Slimline lists 0g sugars per 100ml, but contains aspartame and a source of phenylalanine.
Compare the nutrition panel and ingredients on the exact pack before choosing for a guest’s preferences.
-
Choosing a 1L bottle when separate portions matter
A bottle does not give each guest a separately sealed mixer. Sainsbury’s instructs customers to refrigerate its Indian Tonic Water 1L after opening and use it within three days.
Choose a bottle when the group is likely to use it within the labelled period; consider 150ml multipacks when separate portions or unopened spares matter more.
Brand and own-label references
These examples show differences between specific tonic products and formats, not a judgement about every mixer made by each brand.
Schweppes
Regular and Slimline tonic options are listed in 12 × 150ml formats for separate brunch portions.
- Sainsbury’s lists 4.9g sugars per 100ml for Schweppes regular tonic.
- The Joybuy Slimline listing states 0g sugars per 100ml but names aspartame and a source of phenylalanine.
Fever-Tree
Its listed tonic multipacks include Refreshingly Light Indian and Mediterranean variants in individual 150ml portions.
- The Refreshingly Light Premium Indian 15 × 150ml product lists 3.8g sugars per 100ml.
- “Light” does not mean that this product is sugar-free; check the variant rather than relying on the range name.

The Original Indian Tonic is listed as a 6 × 150ml multipack for a smaller number of separate serves.
- Sainsbury’s product listing states less than 20kcal per 100ml and no artificial sweeteners for this variant.
- Six cans provide fewer separate portions than the listed 12- and 15-can alternatives.
Fentimans
Connoisseurs Tonic Water is a botanical option to consider when its flavour profile fits the planned drinks.
- Fentimans lists quinine and fermented extracts including juniper berry, kaffir lime leaves and lemongrass.
- Check the available pack format if separately portioned mixers are important.
Tesco
Its Indian Tonic Water and Low Calorie Indian Tonic Water are listed in 1L bottles.
- The bottle format suits a group sharing tonic from an opened container.
- A 1L bottle does not provide individually sealed guest portions.

Fever-Tree Refreshingly Light Premium Indian Tonic Water 15 × 150ml
Consider this pack when the group wants 15 separate tonic portions and prefers a lower-calorie variant. It lists 15kcal and 3.8g sugars per 100ml, so it is not sugar-free.
No image available
Schweppes Indian Tonic Water 12 × 150ml
This 12 × 150ml regular tonic pack is an option when guests want a conventional tonic rather than a no-sugar variant. The product information lists quinine and 4.9g sugars per 100ml; confirm whether the individual units are cans or bottles if that matters for serving.

Fever-Tree Refreshingly Light Mediterranean Tonic Water 8 × 150ml
Consider its Mediterranean botanical profile when planning citrus or herbaceous drinks for a smaller group. The pack contains 8 × 150ml; the product information lists 17kcal and 4.2g sugars per 100ml, so it is not sugar-free.

This eight-can pack provides 150ml portions for a group planning regular tonic serves. Its product information lists sugar, quinine and 8.0g sugars per 100ml; it is not a no-sugar option.
Questions about brunch mixers
How many 150ml tonic cans should I allow per guest?
Allow one can for each 150ml mixer portion you plan to serve, rather than assuming one can will cover every guest’s drinks. Fever-Tree’s stated serve uses 150ml of its tonic, so a 12-can pack provides 12 portions at that measure; larger or additional drinks will use more.
Is a light tonic sugar-free?
Not necessarily. Fever-Tree Refreshingly Light Premium Indian lists 3.8g sugars per 100ml, while the Joybuy Schweppes Slimline listing states 0g sugars per 100ml and names aspartame and a source of phenylalanine. Check both the nutrition panel and ingredients.
Can I use a 1L bottle instead of a multipack?
Yes, if the group can share an opened bottle and separate sealed portions are not important. Follow the exact bottle’s storage instructions: Sainsbury’s says to refrigerate its Indian Tonic Water 1L after opening and use it within three days.
What if a guest has an allergy or avoids a particular sweetener?
Read the ingredient and allergen information on the actual pack before serving it. Listings can differ from a later formulation, and the Schweppes Slimline product specifically lists aspartame and a source of phenylalanine.
