Car boot sellers stocking sealed drinks
Choose a pack you can carry and serve as intended. If you plan to sell drinks rather than share them privately, check the organiser's rules and whether your activity needs to be treated as a food business.
Who is choosing these mixers?
Tonic drinkers avoiding added sugar
Diet and slimline tonics offer tonic flavour without a sugar ingredient in the cited products, but their ingredient lists include sweeteners. Check which sweetener is used before choosing a bottle.
Shoppers avoiding sugar and sweeteners
An unsweetened carbonated-water mixer fits this requirement more closely than the cited diet tonics. It changes the drink: soda or sparkling water does not provide tonic's quinine flavour.
What should you check before buying?
Decide whether you want tonic flavour or an unsweetened mixer, then check the ingredients and choose a container that suits your serving plan.
| Priority | What to check | Your needs |
|---|---|---|
| Added sugar | Read the ingredient list for sugar or fructose; use the sugars per 100ml figure to compare the stated nutrition separately. A 'light' name does not settle either question. | I want a mixer with no added sugar, not simply a tonic described as lower calorie. |
| Sweeteners and flavour | Check for acesulfame K, sucralose or aspartame in diet tonic. If avoiding sweeteners too, examine the ingredients of soda or sparkling water and expect a different flavour from quinine tonic. | Tonic flavour matters to me, but I need to decide whether I am comfortable with its listed sweetener. Alternatively, I would rather have an unsweetened mixer. |
| Pack and storage | Compare shared bottles with separately portioned packs. Sainsbury's instructs customers to refrigerate its Diet Indian Tonic Water after opening and use it within three days. | Will drinks be poured throughout the sale, or would sealed individual portions suit my serving plan better? |
| Selling drinks | Ask the organiser about event rules. If buying drinks to resell, check with the relevant local authority whether your activity is a food business. | I am selling refreshments rather than bringing drinks to share, so I need to establish the requirements before stocking up. |
What is easy to overlook?
-
Assuming 'light' means no added sugar
Fever-Tree lists fructose in Refreshingly Light Indian Tonic Water, while Fentimans lists sugar in Naturally Light Tonic Water. Neither ingredient list meets a strict no-added-sugar requirement.
Read the ingredients on the particular tonic you intend to buy, even when its name emphasises lightness.
-
Assuming diet tonic has no sweeteners
The cited Sainsbury's diet tonic contains acesulfame K and sucralose; Tesco's listing for Schweppes Slimline Tonic Water 1L names aspartame.
If you want to avoid both sugar and sweeteners, check an unsweetened water mixer instead and allow for the change in flavour.
-
Opening a shared bottle without a storage plan
Sainsbury's says its Diet Indian Tonic Water must be refrigerated after opening and used within three days.
Choose a shared bottle when you can follow its storage instructions and expect to use it; otherwise, consider sealed individual portions.
A partly used bottle can leave mixer unused after the event.
-
Assuming car boot drink sales need no checks
Food Standards Agency guidance covers food and drink businesses operating from temporary premises, while its community-event guidance says a local authority may treat very limited, infrequent activity differently. Business Companion notes that buying goods specifically to resell can indicate trader status.
Before selling drinks, check the organiser's rules and ask the relevant local authority about your circumstances rather than assuming an exemption.
Which brands offer relevant options?
These examples illustrate differences between specific tonic and water products; a brand name alone does not establish whether another product has added sugar.
Sainsbury's
Its Diet Indian Tonic Water is a 1L tonic option.
- The published ingredients list no sugar ingredient; the nutrition information states less than 0.5g sugars per 100ml.
- It contains acesulfame K and sucralose. Sainsbury's says to refrigerate it after opening and use it within three days.
Schweppes
Slimline Tonic Water offers a branded tonic route; the cited formats include a 1L bottle and a separate 12 × 150ml listing.
- Tesco lists 0g sugars per 100ml for Schweppes Slimline Tonic Water 1L.
- That 1L product lists aspartame, so it is not an unsweetened mixer.
Fentimans
Its Soda Water offers a different route from its tonic products.
- Fentimans lists carbonated water, salt and sodium bicarbonate as the ingredients of its Soda Water, with 0g sugar per 100ml.
- Its Naturally Light Tonic Water lists sugar and 3.4g sugars per 100ml; the soda water does not provide tonic flavour.
Fever-Tree
Its Refreshingly Light Indian Tonic Water is relevant when checking what a 'light' tonic label means.
- Fever-Tree lists fructose in this product's ingredients, so it does not meet a strict no-added-sugar requirement.
Britvic
Britvic announced a zero-sugar Indian Tonic Water 330ml can variant for UK grocery in September 2023.
- If considering that variant for an event, check the current pack for its ingredients and format before buying.
Joybuy mixer options
These options cover separately portioned slimline tonic and sparkling mineral water in smaller or shared bottles. The water options are alternatives when tonic flavour is not required; check each product's current label against your sugar and sweetener requirements.

Schweppes Slimline Tonic Water 12 × 150ml
The 12 separately portioned 150ml cans suit a plan to serve individual tonics rather than open a shared bottle. Check the can label for its ingredients and sweeteners, particularly if aspartame or phenylalanine is a concern.
No image available
San Pellegrino Sparkling Natural Mineral Water 6 × 0.5L
Six 0.5L bottles offer a smaller-bottle sparkling-water alternative for serving at a sale. This is mineral water rather than quinine tonic; check the label if avoiding sugar and sweeteners is your deciding requirement.
No image available
San Pellegrino Sparkling Natural Mineral Water 6 × 1L
The six 1L bottles provide a shared-bottle sparkling-water option rather than individual portions. This is not quinine tonic; plan how you will serve an opened bottle and check the label against your ingredient requirements.
Common questions
Does 'light' tonic mean no added sugar?
No. Fever-Tree Refreshingly Light Indian Tonic Water lists fructose, and Fentimans Naturally Light Tonic Water lists sugar. Check the ingredients of the particular tonic rather than treating 'light' as a no-added-sugar claim.
Is no-added-sugar tonic also free from sweeteners?
Not necessarily. Sainsbury's Diet Indian Tonic Water lists acesulfame K and sucralose, while Tesco's listing for Schweppes Slimline Tonic Water 1L names aspartame. If you want neither sugar nor sweeteners, check an unsweetened water mixer instead, bearing in mind that it will not taste like tonic.
Is a 1L tonic bottle practical for a car boot sale?
A 1L bottle can work for shared serves if you can follow its storage instructions. Sainsbury's says to refrigerate its Diet Indian Tonic Water after opening and use it within three days; sealed individual portions may suit a different serving plan.
Do I need to register before selling sealed mixers at a UK car boot sale?
Do not assume sealed drinks are exempt. Food Standards Agency guidance says food-business registration can apply to sales from temporary premises, while its guidance on limited and infrequent community-event activity allows for a local-authority decision that registration is not needed. Business Companion also notes that buying goods specifically to resell can indicate trader status. Ask the organiser about its rules and the relevant local authority about your activity before trading.
