Parents hosting a mixed-age party
Plan drinks children can have throughout the event, while keeping any fizzy party option separate from the main provision. NHS guidance identifies water and milk as the preferred drinks for children.
Who is choosing the drinks?
Parents comparing sugary and diet mixers
Compare the sugar information on the exact packs, but consider acidity too. The NHS says carbonated drinks are associated with dental erosion whether they contain sugar or lower- or no-calorie sweeteners.
Hosts buying mixers for adults as well
Keep tonic water intended for mixing apart from the children’s main drinks, so its diet or slimline label is not mistaken for a reason to serve it as their usual drink.
What should you check before buying?
Choose the children’s main drinks first, then compare any occasional fizzy option and mixers for adults.
| Priority | What to check | Your needs |
|---|---|---|
| Main drinks | Plan water and plain milk for children. NHS guidance identifies these as the preferred drinks for them. | I want drinks children can have throughout the party without relying on a fizzy mixer. |
| Sugar | Compare sugars per 100 ml and per serving on the exact packs. Check the portion you intend to offer rather than relying on “light” or “diet” wording. | If I offer a fizzy alternative, I want to understand the sugar in the amount served. |
| Acidity | Check whether the drink is carbonated and lists an acid. The NHS says carbonated drinks are associated with dental erosion even when they contain no sugar; child oral-health guidance advises keeping acidic drinks to mealtimes. | I do not want an acidic fizzy drink to become something children sip throughout the event. |
| Ingredients | Read the current pack for sweeteners, quinine and warnings. For example, the Sainsbury’s Diet Indian Tonic with Lemon listing names quinine hydrochloride, acesulfame K and sucralose. | Where an ingredient or warning matters to a guest, I need to check the bottle or can that will actually be served. |
| Drinks table | Identify which purchases are tonic mixers and keep them apart from the children’s main drinks. | I am also buying mixers for adults and want the two drinks selections to be clear. |
Common buying mistakes
-
Assuming zero sugar means tooth-friendly
Removing sugar does not remove the acid-content concern. The NHS associates carbonated drinks with dental erosion whether or not they contain sugar.
Keep water and plain milk as the main drinks. If you offer an acidic fizzy drink, follow child oral-health guidance to serve it with food rather than for repeated sipping.
-
Choosing diet tonic as the children’s default drink
A diet label describes only part of the choice. Tesco Low Calorie Indian Tonic and Sainsbury’s Diet Indian Tonic with Lemon both list quinine and sweeteners.
Decide on the children’s main drinks before buying tonic for a separate mixers table.
-
Relying on a range name instead of the pack
Ingredient lists differ between tonic products. Sainsbury’s lists acesulfame K and sucralose in its Diet Indian Tonic with Lemon, while the Schweppes Slimline Tonic listing carries a phenylalanine warning.
Read the ingredients, nutrition panel and warnings on the exact pack, particularly when a specific ingredient matters to a guest.
Mixer brands and relevant ranges
Fever-Tree
Its Refreshingly Light Indian Tonic is a tonic mixer, rather than a children’s main drink.
- Tesco Groceries describes the 500 ml bottle as having 50% fewer calories than Fever-Tree Premium Indian Tonic Water.
- “Light” does not establish that a drink has no sugar; check the bottle’s nutrition panel.
Schweppes
Its Slimline Tonic is a tonic-water option for a separate mixers table.
- The Sainsbury’s listing for the 1 L Slimline Tonic identifies added intense sweeteners.
- That listing also identifies quinine and a source of phenylalanine; read warnings on the pack being served.
Fentimans
Its Premium Indian Tonic is another tonic mixer to assess by its ingredients, not its flavour description.
- Fentimans lists fructose, citric acid, quinine and a stevia-derived sweetener in this product.
- Those ingredients make the product label relevant when comparing sugar and acids for a party drinks plan.
Tesco
Its own-label Low Calorie Indian Tonic offers a 1 L pack for comparison with other mixers.
- Tesco Groceries lists citric acid, quinine, acesulfame K and sucralose in this tonic.
- Check the pack at purchase rather than assuming “low calorie” settles the choice of drink for children.
Sainsbury’s
Its own-label mixer listings include Diet Indian Tonic with Lemon.
- The Diet Indian Tonic with Lemon listing identifies lemon juice from concentrate and sweeteners.
- It also lists quinine hydrochloride, acesulfame K and sucralose; assess the exact variant before serving.
Britvic
Britvic announced classic and zero-sugar Indian Tonic Water cans for grocery in September 2023.
- The announcement identifies 330 ml cans in both variants.
- A past launch announcement is not a substitute for checking the current pack when choosing party drinks.

Questions about party drinks
Should diet mixers be the main drinks at a kids’ party?
No. The NHS identifies water and milk as the preferred drinks for children. Treat any diet fizzy drink as an occasional, deliberately chosen option rather than the main drinks provision.
Does zero sugar make a fizzy mixer tooth-friendly?
No. The NHS associates carbonated drinks with dental erosion because of their acid content, regardless of sugar or sweetener content. Child oral-health guidance advises keeping acidic drinks to mealtimes and offering water or plain milk between meals.
What should I check on a diet tonic label?
Compare sugars per 100 ml and per serving, then read the ingredients and warnings for acids, sweeteners and quinine. The Sainsbury’s listing for Schweppes Slimline Tonic identifies a source of phenylalanine, so check the exact pack where that warning matters to a guest.
Do “light” and “zero sugar” mean the same thing?
No. Tesco Groceries describes Fever-Tree Refreshingly Light Indian Tonic as having 50% fewer calories than Fever-Tree Premium Indian Tonic Water; that comparison does not establish zero sugar. Check the sugar figure on each product’s nutrition panel instead of treating the terms as interchangeable.
