Households making alcohol-free drinks
If avoiding alcohol is the priority, choose a mixer for its flavour and check the stated ABV of any base drink separately. A light or slimline name describes neither ingredient’s alcohol content.
Who is stocking the pantry?
People moderating spirit serves
If a drink will still contain a spirit, its ABV and the measured pour determine the alcohol units contributed by that spirit. Mixer choice can then be made on taste and nutrition.
Shoppers comparing tonic nutrition
If sugar, calories or sweeteners matter to your choice, compare the exact tonic variants per 100 ml. Those figures do not tell you whether a finished mixed drink is lower in alcohol.
What should you check?
Decide whether you want no alcohol or a lower-unit alcoholic serve before comparing tonic, soda and flavoured mixers.
Alcohol-free serves
Choose this route: When avoiding alcohol matters more than changing the mixer’s calorie or sugar content, check the stated ABV of everything you plan to pour.
Bear in mind: An alcohol-free description need not mean exactly 0.0% ABV; check for an explicit 0.0% label if that is your requirement.
Lower-unit spirit serves
Choose this route: If you still want a spirit, use its ABV and a measured pour to work out the units; the NHS formula is ABV × volume in ml ÷ 1,000.
Bear in mind: Changing the spirit or its measure can change the drink’s flavour balance; switching tonic alone does not reduce the spirit’s units.
| Priority | What to check | Your needs |
|---|---|---|
| Alcohol units | Read the alcoholic base’s ABV and measure the pour. The NHS calculates units as ABV × volume in ml ÷ 1,000. | I still want a spirit in the drink, but I want to know how many units my chosen measure contributes. |
| Alcohol-free serves | Check the stated ABV of the base and mixer. If you require exactly 0.0%, look for that figure on each relevant pack rather than relying on a light or slimline description. | I want to make a drink without assuming that a mixer’s nutrition wording establishes its alcohol content. |
| Nutrition and ingredients | Compare calories and sugars per 100 ml on the exact variants. Read the ingredient list if sweetener choice matters to you. | I would choose between regular and lower-calorie tonic on the mixer’s label, independently of the alcohol decision. |
| Flavour | Decide whether you want bitter tonic, soda water or a more pronounced ginger flavour. Compare the exact flavoured product’s nutrition label too. | Different drinks call for different flavours; I do not want one sweet or strongly flavoured mixer for every serve. |
| Pack format | Match cans or a larger bottle to how often you use mixers. Follow the selected bottle’s storage and opened-life instructions. | For occasional drinks, I would rather open a portioned can than leave a large bottle unfinished. |
Common buying mistakes
-
Reading ‘slimline’ as ‘low alcohol’
A low-calorie tonic does not reduce the units contributed by gin, vodka or another spirit.
Check the spirit’s ABV and measure its pour first. Compare the tonic’s nutrition separately.
-
Assuming ‘alcohol-free’ always means 0.0% ABV
Alcohol-free wording and an exact 0.0% figure are not interchangeable. England’s Department of Health and Social Care guidance describes an alcohol-free threshold of no more than 0.05% ABV for drinks from which alcohol has been extracted.
If exactly 0.0% matters to you, check the ABV stated on the individual base drink and mixer.
-
Opening a large bottle for an occasional serve
The usable time after opening depends on the product. Sainsbury's tells shoppers to refrigerate its Diet Indian Tonic Water after opening and use it within 3 days.
Check opened-life instructions before choosing a large bottle over individual portions.

Treating every flavoured mixer like diet tonic
For the named products, Fentimans lists 4.4 g sugars per 100 ml for Ginger Beer, while Sainsbury's lists under 0.5 g per 100 ml for Diet Indian Tonic Water.
Compare the exact product labels per 100 ml before making a flavoured mixer your routine choice.
Mixer brands and ranges
These brand examples show different tonic and flavoured-mixer choices; the figures apply to the named products, not every drink in a range.
Fever-Tree
Its Indian tonic range includes Premium and Refreshingly Light versions for shoppers choosing between tonic styles.
- Fever-Tree describes its Refreshingly Light Indian Tonic Water as having 50% fewer calories than its Premium Indian Tonic Water.
- That brand comparison concerns calories, not the alcohol content of a spirit-and-tonic.
Britvic
Britvic offers regular and Low Calorie Indian Tonic Water for comparing mixer variants.
- Britvic lists 1 kcal and 0 g sugars per 100 ml for its Low Calorie Indian Tonic Water.
- Check the selected variant’s ingredients and label information if sweeteners matter to you.
Fentimans
Its range includes tonic, soda water and ginger options for different flavour preferences.
- Ginger Beer offers a ginger-flavoured alternative to tonic.
- Fentimans lists 22 kcal and 4.4 g sugars per 100 ml for its Ginger Beer; do not use diet-tonic figures for this product.
Tesco
Tesco lists own-label Indian Tonic Water alongside lower-calorie mixer options.
- Tesco Groceries lists 15 kcal and 3.3 g sugars per 100 ml for Tesco Indian Tonic Water.
- Compare the exact variant’s label rather than applying regular-tonic figures to a low-calorie option.
Sainsbury's
Its Diet Indian Tonic Water comes in a 1-litre bottle for households considering a larger tonic format.
- Sainsbury's lists 2 kcal and under 0.5 g sugars per 100 ml for this diet tonic.
- Its instructions say to refrigerate after opening and use within 3 days; check whether that suits how often you pour tonic.
Schweppes
Schweppes Slimline Tonic Water is among the lower-calorie mixers listed by Tesco Groceries.
- The Slimline range gives shoppers a tonic variant to compare with regular tonic.
- Check nutrition, ingredients and ABV on the particular pack; the range name does not establish the figures for every variant.
Joybuy tonic options
These tonic packs offer individual 150 ml portions for pantry stocking. Choose between slimline, light and regular tonic styles by checking the exact pack label; none determines the alcohol units of a spirit added to it.

Schweppes Slimline Tonic Water, 12 × 150 ml
The 12 × 150 ml can pack suits portioned tonic serves without opening a large bottle. Slimline describes the mixer variant, not the alcohol strength of a drink made with a spirit; check the pack’s ABV if you have a specific alcohol requirement.
No image available
Fever-Tree Refreshingly Light Premium Indian Tonic Water, 15 × 150 ml
This 15 × 150 ml pack provides individual Indian tonic portions for a pantry. Check the exact pack’s nutrition and ABV if light-tonic nutrition or a particular alcohol threshold matters to your serve.
No image available
Fever-Tree Refreshingly Light Mediterranean Tonic Water, 8 × 150 ml
The 8 × 150 ml pack is a portioned Mediterranean tonic option when you want a different tonic style in the pantry. Compare its own nutrition label rather than assuming that every light tonic has the same sugar content; check ABV separately for alcohol-free serves.
No image available
Schweppes Indian Tonic Water, 12 × 150 ml
This regular Indian tonic comes in 12 × 150 ml portions. It is a choice when you want standard tonic rather than a named slimline or light variant; compare nutrition labels if sugar or calories guide your purchase, and check ABV for any alcohol-free serve.
Questions about mixers and alcohol
Does slimline tonic make a gin and tonic low alcohol?
No. Slimline describes the mixer, while the gin’s ABV and the volume poured determine the units it contributes. The NHS calculates alcohol units as ABV × volume in ml ÷ 1,000.
How do I stock mixers for alcohol-free serves?
Choose mixers for the flavour you want, then check the stated ABV of each drink you will combine. If your requirement is exactly 0.0% ABV, look for that explicit figure rather than relying on light, slimline or alcohol-free wording alone.
How long can I keep an opened litre bottle of tonic?
Follow the instructions on that bottle. Sainsbury's says to refrigerate its Diet Indian Tonic Water after opening and use it within 3 days; check the selected product rather than applying that period to every tonic.
Should I buy cans or a larger bottle?
Choose portioned cans if you use mixers occasionally and prefer to open only what you need. A larger bottle may suit more frequent serves, provided you can follow that product’s storage and opened-life instructions.
