Two people planning a few drinks
Individual 150ml or 200ml tonic formats make it easier to plan mixed drinks without opening a sharing bottle. If one drink needs to be alcohol-free, a floral lemonade offers a different flavour from bitter tonic.
Who are these mixers for?
Gin or vodka drinkers choosing a tonic
Fever-Tree suggests its Indian tonic for gin, vodka and fortified wines. Compare its regular and light recipes by flavour, ingredients and nutrition per 100ml rather than assuming they are interchangeable.
People checking sugar and sweeteners
The cited Fever-Tree Refreshingly Light Indian tonic contains fructose and lists 3.8g sugars per 100ml. The cited Schweppes Slimline tonic lists 0g sugars per 100ml but contains aspartame and is labelled as a source of phenylalanine. Check the exact pack before serving.
What should you check before choosing?
Start with how the drink will be served, then compare the recipe and the amount you expect to pour.
| Priority | What to check | Your needs |
|---|---|---|
| Flavour and serve | Check whether the drink is quinine-led tonic or rose-and-lemon lemonade. Treat Fever-Tree’s suggested spirit pairings as manufacturer guidance, not a rule for every drink. | I’m mixing a drink with gin or vodka and want tonic bitterness; for a floral drink without alcohol, I’d choose a lemonade I enjoy on its own. |
| Sugar and sweeteners | Compare sugars and calories per 100ml on the exact products. Sainsbury’s lists 8g sugars per 100ml for Fever-Tree Premium Indian Tonic Water 8x150ml; ASDA lists 3.8g for the cited Refreshingly Light 8x150ml and 0g for Schweppes Slimline 1L. Check ingredients as well. | If sugar or a particular sweetener matters to me, I’ll compare the recipes rather than rely on “light” or “slimline” alone. |
| Pack size | Count the planned drinks and compare individual cans or bottles with a larger bottle. Sainsbury’s gives a serve suggestion of 150ml Fever-Tree mixer with 50ml spirit; use it only if that is the drink you intend to make. | For a small occasion, I want enough mixer for the pours I have planned without opening more than I expect to use. |
| Ingredients | Read the current ingredients and allergen information on the exact pack. The cited Schweppes Slimline label names aspartame and states that the drink contains a source of phenylalanine. | Before serving someone else, I want to check whether the ingredients suit their stated preferences or restrictions. |
What is easy to overlook?
-
Assuming “light” means sugar-free
ASDA lists 3.8g sugars per 100ml for the cited Fever-Tree Refreshingly Light Indian tonic, which contains fructose. Its listing for the cited Schweppes Slimline tonic gives 0g sugars per 100ml.
Compare sugars, calories and sweeteners per 100ml on the products you are considering.
-
Expecting tonic to taste like lemonade
Tonic’s quinine bitterness is distinct from the rose-and-lemon flavour Fentimans describes for its Rose Lemonade. That difference matters if a guest will drink the mixer without a spirit.
Ask which flavour they would enjoy, and consider a non-tonic option for an alcohol-free serve.
-
Overlooking the slimline tonic’s sweetener
The cited Schweppes Slimline tonic contains aspartame and carries a source-of-phenylalanine statement.
Check the current pack with anyone who needs to avoid that ingredient, rather than choosing by the sugar figure alone.
-
Buying a sharing bottle without counting serves
A 150ml can and a larger bottle meet different serving plans, even when both contain tonic.
Estimate the number and size of drinks before choosing a format.
Opening more mixer than you use may leave you with a partly used bottle for another occasion.
Which brands and ranges are relevant?
These are references for comparing mixer styles and formats, not a list of products available in the Joybuy selection below.
Fever-Tree
Indian tonic options for quinine-led drinks; Fever-Tree suggests its Premium Indian Tonic Water for gin, vodka and fortified wines.
- The cited regular and Refreshingly Light 8x150ml products offer individual cans.
- Their recipes differ: Sainsbury’s lists 8g sugars per 100ml for the cited regular tonic, while ASDA lists 3.8g for the cited Refreshingly Light version.
Fentimans
Its range includes tonic waters and floral sparkling soft drinks such as Rose Lemonade.
- Fentimans describes Rose Lemonade as rose-and-citrus flavoured and lists a 275ml bottle.
- Rose Lemonade is not a substitute for tonic bitterness; Fentimans lists 4.4g sugars per 100ml.
Schweppes
A tonic range that includes a slimline recipe and individual-bottle formats.
- ASDA lists 0g sugars and 2kcal per 100ml for the cited Schweppes Slimline 1L bottle.
- That product contains aspartame and is labelled as a source of phenylalanine; check the label of the format you buy.
Britvic
Britvic announced classic and zero-sugar Indian tonic in 330ml six-packs in 2023, describing each can as two serves.
- The announced can size offers another format to consider when planning pours.
- Check the current product and label before relying on that historical range information.
Tesco
Tesco’s mixer listings include own-label soda water and low-calorie Indian tonic alongside named-brand products.
- The range provides a way to compare tonic with a non-tonic soda-water option.
- Use the exact current product label for ingredients and nutrition rather than treating a category listing as a product specification.

Fever-Tree Naturally Light Tonic Water 8x150ml
Eight 150ml cans offer individual portions for planned tonic drinks. If the light recipe is part of your choice, compare its sugars and ingredients on the exact pack.
No image available
Schweppes Slimline Tonic Water 12x150ml
This pack contains twelve 150ml cans for portioned tonic drinks. Check the current ingredients and source-of-phenylalanine statement if the sweetener matters to anyone being served; twelve cans may exceed a two-person plan.
No image available
Fever-Tree Refreshingly Light Mediterranean Tonic Water
Consider this Mediterranean tonic if you want to compare a different tonic style with an Indian tonic for a mixed drink. Check the exact pack size and ingredients before buying; “light” alone does not establish that a drink is sugar-free.
No image available
Fever-Tree Indian Tonic Water 8x150ml
Eight 150ml cans suit individually planned Indian-tonic serves. Fever-Tree suggests this tonic style for gin and vodka; check the pack’s sugar figure if comparing it with a light or slimline recipe.
No image available
Fever-Tree Refreshingly Light Premium Indian Tonic Water 15 x 150ml
This light Indian tonic comes in fifteen 150ml cans, so count the planned drinks before choosing it for a small occasion. The cited Refreshingly Light Indian tonic recipe contains fruit sugar; check the exact pack label rather than assuming “light” means sugar-free.
Questions about sparkling mixers
How do regular, light and slimline tonics differ?
Compare the exact products per 100ml and then read their ingredients. Sainsbury’s lists 36kcal and 8g sugars per 100ml for Fever-Tree Premium Indian Tonic Water 8x150ml; ASDA lists 15kcal and 3.8g sugars for the cited Fever-Tree Refreshingly Light 8x150ml, and 2kcal and 0g sugars for Schweppes Slimline 1L. The cited light tonic contains fructose, while the cited slimline tonic contains aspartame.
What can I serve if one person is not drinking alcohol?
Choose a sparkling drink they would enjoy on its own. Fentimans describes its Rose Lemonade as rose-and-citrus flavoured and lists a 275ml bottle; tonic is another alcohol-free mixer, but its quinine bitterness is a different flavour choice.
Should I buy individual cans or a larger bottle?
Count the drinks and the mixer needed for each before choosing a format. For one suggested mixed serve, Sainsbury’s gives 150ml Fever-Tree tonic with 50ml spirit; individual cans may be convenient for that plan, while a larger bottle makes more sense if you expect to pour several drinks from it.
Which label details matter when serving someone else?
Check the exact pack’s ingredients, nutrition and allergen information against that person’s needs. GOV.UK guidance explains that prepacked foods require label information and that specified allergens must be identified when they are ingredients. If considering the cited Schweppes Slimline tonic, note its aspartame ingredient and source-of-phenylalanine statement.
