Hosts serving classic mixed drinks to a group
If several guests will use the same tonic, a shared bottle may fit the menu. Consider how many bottles you are likely to open and whether you can refrigerate and finish them afterwards.
Who is choosing the mixers?
Hosts offering a diet tonic choice
Keep regular and diet varieties identifiable. Check each pack’s nutrition and ingredients rather than assuming that tonics with similar names have the same formulation.
Hosts planning a small selection of distinctive serves
A botanical or flavoured tonic may suit a planned gin, vodka or alcohol-free drink. Work out how many of those serves you expect before choosing its pack format.
What should you check before buying?
Start with the drinks you intend to make, then choose pack sizes and tonic varieties that suit how many guests are likely to use each one.
| Priority | What to check | Your needs |
|---|---|---|
| Drinks menu | Decide where a classic Indian tonic works and where a grapefruit or botanical flavour is intentional. Check the flavour named on the exact pack. | I want a tonic that suits the drinks I plan to serve, rather than using a distinctive flavour in every glass. |
| Pack format | Compare total volume, individual portion size and the number of bottles likely to be opened. Check post-opening storage instructions on bottled mixers. | Several guests may share one classic tonic; for a less-requested flavour, I would rather open a smaller portion when needed. |
| Regular or diet | Read nutrition per 100ml and the sweetener ingredients on each variant. Sainsbury’s Diet Indian Tonic Water lists 2kcal per 100ml and contains acesulfame K and sucralose. | I want guests to be able to identify a diet choice without mistaking it for regular tonic. |
| After the party | Check refrigeration and use-by-after-opening instructions. Sainsbury’s 1L tonic pages say to refrigerate after opening and use within three days. | If only a few drinks will use a particular mixer, I want a pack I can reasonably finish. |
What can disrupt the plan?
-
Planning around a temporary offer
A promotion may no longer apply when you place the order or choose a delivery slot.
Check the final basket before committing, especially if your plan depends on a loyalty offer.
-
Using a distinctive tonic for every drink
A grapefruit or botanical tonic has a different role from the classic tonic intended for repeated serves; not every guest will want the same flavour.
Plan the shared mixer first, then choose a separate quantity for drinks that call for a particular tonic.
-
Treating regular and diet tonic as interchangeable
Formulations vary. Ocado’s Schweppes standard-tonic listing includes sugar and sodium saccharin, while Sainsbury’s diet tonic lists different sweeteners.
Read the exact packs and keep the variants clearly labelled when serving them.
-
Opening too many large bottles
Part-used bottles need attention after the party. Sainsbury’s 1L tonic and Fentimans Pink Grapefruit Tonic both instruct customers to refrigerate after opening and use within three days.
Use larger bottles for mixers you expect to serve repeatedly; consider smaller units for flavours with uncertain demand.

Schweppes Slimline Tonic Water 12 × 150ml
The 12 small units suit individually portioned tonic drinks. The product information identifies aspartame as an ingredient and notes that it is a source of phenylalanine; check the current label where that matters to a guest.

Schweppes Indian Tonic Water 12 × 150ml
This classic Indian tonic comes as 12 small units for portioned serves. Confirm whether the units are cans or bottles before ordering, as the product descriptions differ on that detail; the regular formulation includes sugar and sodium saccharin.
No image available
Double Dutch Skinny Tonic 24 × 200ml
The 24-unit pack suits a menu calling for several smaller tonic portions. Its product description names grapefruit and juniper alongside quinine; check the pack’s nutrition panel if those details affect your choice.
No image available
Fever-Tree Refreshingly Light Premium Indian Tonic Water 15 × 150ml
This 15-unit Indian tonic pack allows for individually portioned serves. Refreshingly Light is a distinct formulation from the regular Fever-Tree tonic; it contains fruit sugar, so check its label rather than treating it as sugar-free.
No image available
Fever-Tree Indian Tonic Water 8 × 150ml
The eight small units can be set aside for planned classic-tonic serves. This is the regular Indian tonic, not the Refreshingly Light variant; its product description includes sugar, so check the exact label when choosing between them.
Christmas party mixer questions
Should I buy 1L bottles or small cans?
Choose 1L bottles when several guests are likely to use the same tonic and you can store what remains as directed. Small cans let you open individual portions when demand is less predictable. Sainsbury’s 1L tonic instructions say to refrigerate after opening and use within three days.
Are regular, diet and slimline tonic interchangeable?
No: check the ingredients and nutrition on each exact variant. Sainsbury’s Diet Indian Tonic Water lists acesulfame K and sucralose, while Ocado’s Schweppes standard-tonic listing includes sugar and sodium saccharin. Keep different varieties identifiable when serving guests.
What should I check for guests with dietary requirements?
Read the label on the pack you will serve, including its ingredients and any relevant dietary statements, rather than relying on a similar product name. GOV.UK guidance for prepacked food requires mandatory food information and says labelling must be accurate and not misleading.
What should I do with opened mixer bottles after the party?
Follow each bottle’s storage instructions and note when it was opened. Sainsbury’s 1L tonic and Fentimans Pink Grapefruit Tonic both specify refrigeration and use within three days after opening; instructions for another mixer may differ.
