Regular home mixers
If you use tonic or soda water often, a larger bottle may suit your routine. Tesco Groceries lists 1-litre own-label tonic alongside other bottle and multipack formats; choose an amount you expect to use.
Who is choosing a mixer?
Drinkers choosing a particular flavour
If the mixer is meant to contribute citrus, elderflower, berry or botanical notes, check the variant rather than choosing by brand alone. Fever-Tree lists several flavoured tonics, while Fentimans describes botanical tonic options.
Shoppers comparing light tonics
Check nutrition per 100 ml and ingredients on the exact variant instead of treating light and slimline labels as interchangeable. Fentimans lists 18 kcal and 3.4 g sugars per 100 ml for its Naturally Light Tonic Water.
What should you check?
Choose the mixer type for the drink first, then check whether its flavour, pack format and label suit how you will use it.
| Priority | What to check | Your needs |
|---|---|---|
| Mixer type | Decide whether the drink calls for tonic or soda water. Check whether a tonic is plain or flavoured. | I want a sparkling base that fits the drink, without adding a flavour I did not intend. |
| Pack format | Compare total volume and individual serving size. Consider when you will use an opened bottle or portion. | For frequent mixing, I might use a larger bottle; for occasional drinks, I would rather open one small portion at a time. |
| Flavour | Read the exact variant name and ingredients. Fever-Tree lists flavours including elderflower, lemon, and rhubarb and raspberry. | If the tonic will be noticeable in the finished drink, I want its stated flavour to suit what I am mixing. |
| Nutrition | Compare energy and sugars per 100 ml on the exact product. Fentimans lists 18 kcal and 3.4 g sugars per 100 ml for Naturally Light Tonic Water. | I want to compare light and standard tonics using their labels, not assume the names describe the same recipe. |
Common buying mistakes
-
Assuming all light tonics have the same recipe
Nutrition figures and ingredients apply to the particular tonic and variant on the label, not to every product described as light or slimline.
Compare energy and sugars per 100 ml, and read the ingredients of the exact pack you plan to buy.
-
Choosing a flavoured tonic when you want a plain mixer
Elderflower, citrus, berry and botanical variants contribute their own flavour to the finished drink.
Choose plain tonic or soda water when you do not want those added flavour notes; select a flavoured variant when its stated profile fits the drink.
Brand and retailer references
These ranges illustrate different mixer types and formats; a brand name alone does not establish which variant suits your drink.
Tesco
Tesco Groceries lists own-label 1-litre Indian tonic, lower-calorie tonic and soda water options.
- The listed types cover both tonic and soda water for regular home mixing.
- Check the exact variant and ingredients when choosing between them.
Schweppes
Schweppes tonic appears in a 1-litre bottle in Tesco Groceries listings and as a 12 × 150 ml Indian Tonic Water pack on Joybuy.
- The stated formats allow a choice between a larger bottle and individual portions.
- Check the pack description if the container type matters: the supplied Joybuy information for the 12 × 150 ml pack conflicts on whether it contains cans or bottles.
Fever-Tree
Fever-Tree lists Indian, Mediterranean and several flavoured tonic waters, including elderflower and rhubarb and raspberry.
- The range offers distinct stated flavour profiles for different drinks.
- Check the exact flavour and pack rather than assuming one variant represents the whole range.
Fentimans
Fentimans describes botanical tonic variants including Connoisseurs and Naturally Light.
- Fentimans lists product-specific nutrition: Connoisseurs has 20 kcal and 4.4 g sugars per 100 ml; Naturally Light has 18 kcal and 3.4 g sugars per 100 ml.
- Those figures describe the named variants, not every Fentimans mixer.
Britvic
Britvic announced 330 ml six-packs of Indian Tonic Water in classic and zero-sugar variants for grocery retail in September 2023.
- The announcement identifies a canned tonic format and two named variants.
- Check the exact pack and variant when shopping; the announcement describes the range at its 2023 launch.

Frequently asked questions
Should I choose a 1-litre bottle or smaller portions?
Choose according to how often you will use the mixer. A larger bottle suits repeated drinks, while smaller portions let you leave the rest of a pack unopened until needed. Check the total volume and any storage instructions on the exact product.
Are light and slimline tonics interchangeable?
No: compare the nutrition panel and ingredients of the exact variants. Fentimans lists 18 kcal and 3.4 g sugars per 100 ml for Naturally Light Tonic Water; those figures do not describe other light or slimline tonics.
How should I store an opened sparkling mixer?
Follow the instructions on the exact pack. The Joybuy information for Fever-Tree Indian Tonic Water 8 × 150 ml advises refrigerating it after opening and consuming it within three days; instructions for other products may differ.
