Hosts serving a larger group
If tonic will be poured throughout the buffet, larger bottles may suit that repeated demand. Plan how many you will open so that less is left unused.
Who is this for?
Hosts catering for different preferences
A standard tonic and a clearly identified diet or low-calorie option give guests a choice of sweetness profiles. Check the ingredients if sweeteners matter to anyone attending.
Hosts planning a small drinks station
If particular spirits or alcohol-free drinks are on the menu, a limited choice of botanical tonic can serve those planned pairings without making it the default mixer for everyone.
What should you check?
Choose the mixer styles guests are likely to use, then match bottle and can sizes to the expected number of serves.
| Priority | What to check | Your needs |
|---|---|---|
| Pack size | Compare total volume and the number of serves you expect. A 1-litre bottle and a 150ml can suit different patterns of use. | I will pour plenty of one mixer, but I may want smaller unopened portions of a flavour only a few guests choose. |
| Sugar and sweeteners | Read sugars per 100ml and the ingredients list. Tesco lists 0g sugars per 100ml for its Low Calorie Indian Tonic Water, while Sainsbury’s lists 4.2g per 100ml for its standard Indian tonic; the listed recipes contain sweeteners. | Some guests may prefer a lower-sugar tonic, while others may want the standard version. I can identify both clearly at the drinks station. |
| Flavour fit | Match a botanical tonic to a drink you plan to make. Fentimans describes botanical extracts and quinine in its Connoisseurs Tonic; Fever-Tree lists several distinct tonic styles. | A particular gin or alcohol-free drink is on the menu, but I do not need every mixer to have that flavour profile. |
| Opened bottles | Check each bottle’s storage instructions. Tesco’s listed low-calorie tonic and Sainsbury’s listed diet tonic say to refrigerate after opening and use within 3 days. | If only a few people will choose a mixer, I would rather avoid opening a large bottle for one or two drinks. |
Common buying mistakes
-
Buying only one sweetness profile
Standard and diet or low-calorie tonics have different sugar declarations and ingredients, so one choice may not suit every guest’s preference.
Check the labels and identify each option clearly when serving.
-
Opening more large bottles than you need
The listed Tesco low-calorie and Sainsbury’s diet tonics instruct users to refrigerate opened bottles and use them within 3 days.
Estimate likely serves before opening bottles; consider small cans for a mixer that few guests will choose.
An opened bottle may leave more mixer to use after the buffet.
-
Treating botanical tonic as an all-purpose mixer
Botanical ingredients and flavour styles are relevant to particular drinks, not a guarantee that every guest will prefer the pairing.
Choose a botanical variant for a drink you intend to serve, alongside a more familiar mixer option.
Brand and own-label options
These examples illustrate differences in bottle size, sweetness and flavour; they do not imply that every product in a brand’s range is alike.
Tesco
Tesco lists a 1-litre Low Calorie Indian Tonic Water for hosts considering a larger bottle.
- The listed tonic declares 0g sugars per 100ml.
- It contains sweeteners, so low calorie does not mean unsweetened.
Sainsbury's
Sainsbury’s lists standard and diet Indian tonic in 1-litre bottles.
- The listed standard tonic declares 4.2g sugars per 100ml; the diet version declares less than 0.5g per 100ml.
- The listed diet tonic should be refrigerated after opening and used within 3 days.
Schweppes
Schweppes offers Indian tonic in small cans, as well as a Slimline tonic option.
- The Joybuy Indian Tonic Water listing identifies a 12 x 150ml pack for individual serves.
- Check the specific recipe: the listed Indian tonic contains sugar and sodium saccharin.
Fentimans
Fentimans describes botanical ingredients in its Connoisseurs and Premium Indian tonics.
- Fentimans lists botanical extracts and quinine in Connoisseurs Tonic.
- Its Connoisseurs Tonic lists 4.4g sugars per 100ml; check whether its flavour fits the planned drink.
Fever-Tree
Fever-Tree lists several tonic styles, including Indian, Mediterranean, elderflower and aromatic variants.
- Different styles allow a host to choose a tonic for a particular planned pairing.
- Check the exact variant rather than assuming the range shares one flavour or recipe.
Britvic
Britvic announced classic and zero-sugar Indian tonic in 330ml six-packs in September 2023.
- Britvic described each 330ml can as providing two serves.
- Check the pack and variant when shopping rather than relying on the historical launch description.

Frequently asked questions
Should I buy 1-litre tonic bottles or small cans for a buffet?
Choose 1-litre bottles for tonic you expect to pour repeatedly, and consider small cans for individual serves or less-requested flavours. Estimate how much you will open: the listed Tesco low-calorie and Sainsbury’s diet tonic bottles say to refrigerate after opening and use within 3 days.
How can I offer a tonic with less sugar?
Offer a clearly labelled diet or low-calorie tonic alongside standard tonic, and check its ingredients. Tesco’s listed low-calorie tonic declares 0g sugars per 100ml and contains acesulfame K and sucralose; Sainsbury’s listed diet tonic declares less than 0.5g sugars per 100ml.
How long can I keep an opened tonic bottle?
Follow the instructions on the particular bottle. Tesco’s listed low-calorie tonic and Sainsbury’s listed diet tonic instruct users to refrigerate after opening and use within 3 days, which matters when planning how many bottles to open for a one-day buffet.
Do botanical tonics suit every buffet drink?
No single botanical flavour needs to serve every drink. Fentimans describes botanical ingredients in its Connoisseurs Tonic, while Fever-Tree lists several tonic styles; choose a variant for a pairing you have planned and offer another mixer for guests who prefer something different.
