Shoppers starting a small drinks cupboard
If you want a few distinct options rather than several similar tonic flavours, start with a tonic you expect to use. Soda water adds a different, more neutral sparkling choice.
Who are these mixers for?
People planning gin or alcohol-free serves
Start with the drink you intend to make. Indian tonic brings its own bitter flavour; a floral or citrus tonic is a more deliberate flavour choice. Fever-Tree and Fentimans describe different profiles in their ranges, but a suggested pairing cannot tell you which you will prefer.
Shoppers deciding between bottles and cans
Consider how many drinks you will make at once. A larger bottle and individual cans serve different opening and portion needs, so check the pack size before putting several mixers in the trolley.
What should you choose first?
Choose the sparkling base for your planned drinks before deciding whether a different tonic formulation or a specific flavour deserves space in your first shop.
| Priority | What to check | Your needs |
|---|---|---|
| Mixer type | Check whether the product is Indian tonic, soda water or another sparkling drink. Tonic has a bitter flavour; soda water is the more neutral choice. | I want tonic for a drink that calls for its bitterness, but soda water if I want bubbles without that tonic flavour. |
| Tonic formulation | Check the exact product name, ingredients and nutrition label when choosing between standard, slimline, light and low-calorie tonics. | If I prefer a slimline tonic, I want to choose it deliberately rather than assume it has the same formulation as standard tonic. |
| Flavour | Look for a named citrus, floral, herbal or fruit profile. Fever-Tree and Fentimans list several such tonic variants alongside Indian tonic. | A flavoured tonic makes sense when I have a particular drink in mind; otherwise, I would start with a familiar base. |
| Pack format | Compare the stated volume and number of bottles or cans, then consider how much mixer you expect to use after opening one. | Individual cans suit the way I make one drink at a time; a larger bottle suits me if I expect to use more of it. |
| Ingredient checks | Read the exact pack if an ingredient matters to you. The electronic Medicines Compendium quinine sulfate leaflet identifies tonic water as a possible source of quinine in its allergy warning. | With a known quinine allergy or previous reaction, I need to check the drink rather than assume all sparkling mixers are interchangeable. |
What is easy to overlook?
-
Buying several flavoured tonics before choosing a drink
Fever-Tree and Fentimans list citrus, floral and other tonic profiles. Those flavours make a more specific choice than a familiar Indian tonic and may not suit every serve you plan.
Start with the mixer for your usual drink, then try a flavoured tonic when you have a particular serve in mind.
-
Treating tonic and soda water as substitutes
Tonic contributes a bitter flavour, whereas soda water is a more neutral sparkling base. Choosing only one may leave you without the type a planned drink calls for.
If you want both kinds of drink, consider one tonic and one soda water before adding more tonic flavours.

Skipping the label when quinine matters
The electronic Medicines Compendium quinine sulfate leaflet includes quinine in tonic water in its allergy warning. A familiar-looking sparkling drink should not replace a check of the exact pack.
If you have a known allergy, previous reaction or medicine-related concern, check the label and ask a pharmacist or clinician for advice about your circumstances.
Which brands offer these options?
These ranges illustrate the types of mixer you may encounter; a brand name alone does not tell you which flavour or format suits your drinks.
Fever-Tree
Its UK range includes Indian tonic and several light, floral and aromatic variants.
- The Fever-Tree range lists Mediterranean, aromatic and elderflower profiles for shoppers seeking a named tonic flavour.
- The brand suggests spirit pairings, but those suggestions cannot establish which pairing you will enjoy.
Schweppes
Tesco lists its standard tonic, slimline tonic and soda water as distinct products.
- Those listed types let you choose between bitter tonic, a slimline formulation and soda water.
- Check the exact pack and label rather than treating the three mixers as equivalent.
Fentimans
Its mixer range spans Indian tonic, fruit-flavoured tonics, soda water and ginger drinks.
- Fentimans lists orange, grapefruit, elderflower, rhubarb and yuzu tonic variants for specific flavour preferences.
- Its botanical descriptions and pairing suggestions are the maker’s guidance, not a guarantee that a flavour suits every drink.
Britvic
Britvic has documented Indian tonic, lower-calorie tonic, soda and other mixer formats in its range announcements.
- Britvic’s 2016 announcement described small bottles and cans across several mixer types; a 2023 announcement described classic and zero-sugar Indian tonic cans.
- Those announcements describe formats at the time, so check the current listing before planning around a particular pack.
Tesco
Tesco’s own-label range includes listed soda water and low-calorie Indian tonic multipacks.
- Its listings give shoppers another way to compare mixer type and pack size.
- An own-label tonic should not be assumed to taste the same as a branded one; check the exact product you intend to buy.

Frequently asked questions
What should go in a first sparkling-mixer shop?
Start with one tonic type you expect to use: standard Indian tonic or a slimline or lower-calorie version if that is your preference. Add soda water if you also want a more neutral sparkling base; treat flavoured tonics as additions for particular drinks.
Should I buy individual cans or a larger bottle?
Choose the pack format around how many drinks you expect to make after opening it. Individual cans let you open one portion at a time, while a larger bottle may suit several drinks; check the volume on the exact pack.
Is slimline tonic the same as standard tonic?
No: choose a slimline, light or low-calorie tonic as the particular product it is, not on the assumption that its ingredients or flavour match a standard version. Compare the labels of the exact packs you are considering.
What if quinine has caused a previous reaction?
Do not assume tonic water is suitable. The electronic Medicines Compendium quinine sulfate leaflet mentions quinine in tonic water in its allergy warning; check the drink’s label and ask a pharmacist or clinician about an individual concern.
Can I count on a mixer being in my local shop?
Check stock close to your visit if you need a particular mixer. Sainsbury’s says its store stock checker is indicative and cannot guarantee an item will remain available when you arrive.
