Hosts serving several guests
If everyone is happy with one mixer, a shared bottle is worth comparing with multipacks by unit price. Consider whether you will use what remains after lunch.
Who is choosing?
Shoppers comparing sugar and sweeteners
Regular, diet, slimline and light tonics can have different ingredients and nutrition values. Compare the named products' labels rather than relying on the wording on the front of the pack.
Hosts offering a choice of flavours
A floral or botanical tonic may appeal when its flavour is part of the drink, whether served on its own or with a spirit. For a group with different preferences, consider whether a standard mixer is also needed.
What matters when buying mixers?
Start with how many people will share each flavour, then compare pack sizes and labels on the products you are considering.
| Priority | What to check | Your needs |
|---|---|---|
| Pack size and cost | Compare the displayed price per litre or per 100 ml for the exact packs. Check the number and size of individual units, and the opened-bottle instructions. | Several of us will drink the same mixer, so a shared bottle could work. If we want separate servings or flavours, I would compare smaller units instead. |
| Sugar and sweeteners | Read sugars per 100 ml, serving size and the ingredients list. Sainsbury's lists 0 g sugars per 100 ml for Schweppes Slimline Tonic Water 1L; that figure describes this variant, not every light tonic. | I want to know what is in each option before serving more than one glass, especially if a guest asks about sugar or sweeteners. |
| Flavour | Check whether the product is standard tonic, soda or a specifically flavoured tonic. Fever-Tree describes its Elderflower Tonic Water as combining elderflower flavour with quinine bitterness. | For guests who want a straightforward mixer, I would not assume a floral or botanical tonic suits everyone. A distinctive flavour makes more sense when it is a deliberate choice. |
| Ingredients and storage | Check the current pack for quinine, sweeteners, declared allergens and instructions after opening. Use the label of the exact variant being served. | If someone needs to avoid an ingredient, I need to check their particular drink. I also want a pack size that fits when we will use it. |
Buying mistakes to avoid
-
Choosing by pack price alone
A bottle and a multipack contain different amounts, and some of a larger bottle may be left over.
Compare the exact products' unit prices at the retailer, then choose an amount your guests are likely to use.
-
Assuming every light tonic is sugar-free
Names do not give a consistent sugar figure across brands and variants. Sainsbury's lists 0 g sugars per 100 ml for Schweppes Slimline Tonic Water 1L, while its Fever-Tree Refreshingly Light Aromatic Tonic listing describes a different product with fewer calories than Fever-Tree Premium Indian Tonic Water.
Compare the sugars and energy values per 100 ml on each current label, and read the ingredients if sweeteners matter to your guests.
-
Buying a distinctive tonic for the whole group
Fever-Tree's elderflower tonic and Fentimans' botanical Connoisseurs Tonic Water have particular flavour profiles; neither is automatically a substitute for standard tonic or soda.
Choose those flavours when guests want them, rather than relying on one flavoured mixer for every drink.
-
Relying on an old online ingredient list
The pack being served is the relevant place to check its current ingredients and instructions.
Read that label before serving, particularly when a guest needs information about an allergen, quinine or a sweetener.
Brand and own-label options
These ranges illustrate different formats and flavours to compare; a brand reference does not mean every variant has the same ingredients or is available at every retailer.
Tesco
Tesco Groceries lists own-label 1-litre tonic options, including low-calorie Indian tonic.
- A shared-bottle format to compare with smaller packs.
- Check the current unit price and the label of the particular variant.
Sainsbury's
Sainsbury's lists regular Indian Tonic Water and Diet Indian Tonic Water with Lemon in 1-litre bottles.
- Two named shared-bottle options with different formulations.
- Compare their current nutrition panels, ingredients and opened-bottle instructions separately.
Schweppes
Schweppes offers standard and slimline tonic formats. Sainsbury's lists 0 g sugars per 100 ml for its Schweppes Slimline Tonic Water 1L.
- The named slimline variant gives a specific sugar figure to compare with other labels.
- Check ingredients and pack size for the exact variant; the 1-litre figure does not describe every Schweppes tonic.
Fever-Tree
Fever-Tree describes its Elderflower Tonic Water as floral, with quinine bitterness.
- A named flavour to consider when guests want elderflower tonic.
- Do not assume other Fever-Tree variants have the same flavour or nutrition values.
Fentimans
Fentimans describes its Connoisseurs Tonic Water as a botanical tonic.
- A specific botanical option when that flavour is wanted.
- Check the current pack and unit price before choosing it for a group.
Britvic
Britvic identifies mixers within its drinks range. Its detailed tonic relaunch announcement dates from October 2016.
- A brand reference if comparing mixer ranges.
- Check a current listing for the particular product and size you intend to buy.

Schweppes Indian Tonic Water 12 × 150 ml
This 12-pack of 150 ml units suits a lunch where guests want separate servings of standard tonic. Compare its unit price and label with the slimline variant rather than treating the two as interchangeable.

No image available
Fever-Tree Refreshingly Light Premium Indian Tonic Water 15 × 150 ml
Fifteen 150 ml units may suit a larger group or guests having more than one serving. The name alone does not establish its sugar content; read the current nutrition panel when comparing light tonics.

Double Dutch Skinny Tonic 24 × 200 ml
This pack contains 24 units of 200 ml each. Check the container type if individual-serving convenience matters, and use the current pack label when comparing its nutrition information.
Common questions
Should I buy a 1-litre bottle or individual tonic units for a ploughman's lunch?
Choose a 1-litre bottle if several guests want the same flavour and you expect to use it soon after opening. Smaller units suit separate servings or a choice of mixers; compare the exact packs' unit prices and check bottle storage instructions before buying.
Does 'light' or 'slimline' always mean sugar-free?
No: check the nutrition panel of the named variant. Sainsbury's lists 0 g sugars per 100 ml for Schweppes Slimline Tonic Water 1L, but that figure does not establish the sugar content of other light or slimline tonics.
What should I check if a guest needs to avoid an ingredient?
Check the current label of the exact mixer you will serve, including its ingredients and declared allergens. Tonic variants can differ in quinine, sugar and sweeteners, so an older online listing should not replace the pack label.
Can I serve tonic without alcohol at lunch?
Yes, if guests want it that way. Fever-Tree describes its Elderflower Tonic Water as a drink in its own right; consider whether guests want its floral flavour and quinine bitterness, or would prefer another soft-drink option.
