Choose plain still or sparkling water if you want an unflavoured drink alongside your snack; the NHS also suggests diet, sugar-free or no-added-sugar drinks as swaps for sugary drinks. If you prefer fruit flavour, check the exact product’s sugars, energy and ingredients rather than assuming every flavoured water is sugar-free. Treat caffeinated functional water separately: Buxton lists 75mg caffeine and 9.2g sugars per bottle for Peak FOCUS.
Plain water keeps the drink unflavoured. If fruit flavour matters, compare a sugar-free flavoured water’s nutrition panel and ingredients with those of the regular version; the NHS includes sugar-free drinks among its suggested swaps.
Plain sparkling water offers carbonation without choosing a flavoured drink. Buxton describes its sparkling natural mineral water as containing no calories; check that the bottle you pick is the plain version.
A water-branded drink can contain caffeine and sugar. Buxton lists 75mg caffeine and 9.2g sugars per bottle for Peak FOCUS, so its label matters if you are choosing a drink for an afternoon snack rather than seeking caffeine.
Decide whether you want plain water, fizz or fruit flavour, then compare the exact bottle’s label and a size you can use as directed after opening.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars and energy | Read sugars and energy per 100ml and per stated serving. Check whether a flavoured drink is labelled sugar-free or contains sugar. | I’m replacing a sugary soft drink and want to know what the drink adds alongside my snack. The NHS suggests diet, sugar-free or no-added-sugar drinks as alternatives. |
| Fruit flavour | Compare the ingredients as well as the nutrition panel. Volvic lists 0g sugars and 2 kcal per 250ml for Touch of Strawberry Sugar Free; it describes its regular Touch of Fruit range as containing a little sugar and less than 27 calories per serving. | Fruit flavour appeals to me, but I don’t want to mistake a regular flavoured water for its sugar-free counterpart. Sweeteners and preservatives may also affect which ingredients I choose. |
| Carbonation | Confirm that the bottle is plain sparkling water rather than a flavoured or functional drink. Buxton describes its sparkling natural mineral water as containing no calories. | I’d like fizz with my snack, without choosing a sweetened fruit flavour. If I don’t enjoy carbonation, still water suits that preference instead. |
| Caffeine | Check caffeine per bottle and any label warning. Buxton lists 75mg caffeine, 9.2g sugars and 40 kcal per bottle for Peak FOCUS, and marks it as high in caffeine. | I don’t want caffeine to be an unexpected part of an afternoon drink. Buxton says Peak FOCUS is not recommended for children or people who are pregnant or breastfeeding. |
| Bottle size and storage | Check bottle volume, pack count and the exact after-opening directions. Tesco instructs buyers of its 2L British Natural Mineral Water to refrigerate it after opening and consume it within 3 days. | For a snack away from home, I may prefer a smaller bottle; at a desk or at home, I can choose a larger format if I’ll use it within its labelled period. |
Volvic lists 0g sugars and 2 kcal per 250ml for Touch of Strawberry Sugar Free. Its regular Touch of Fruit range contains a little sugar and is described as having less than 27 calories per serving; the ranges are not nutritionally identical.

No. Volvic lists 0g sugars and 2 kcal per 250ml for Touch of Strawberry Sugar Free, but its ingredients also include potassium benzoate, acesulfame K and sucralose. Read the ingredient list alongside the nutrition panel if those ingredients affect your choice.
No. Volvic describes its regular Touch of Fruit range as containing a little sugar and stevia leaf extract, with less than 27 calories per serving. Its Touch of Strawberry Sugar Free product instead lists 0g sugars and 2 kcal per 250ml, so compare the exact flavour and serving size.
Choose it only if you want a caffeinated drink and its label suits you. Buxton lists 75mg caffeine, 9.2g sugars and 40 kcal per bottle for Peak FOCUS, and says its high caffeine content makes it unsuitable for children or people who are pregnant or breastfeeding. The NHS advises drinking caffeine in moderation.
Follow the directions on that bottle. Tesco instructs buyers of its 2L British Natural Mineral Water Still to refrigerate it after opening and consume it within 3 days; a Highland Spring 6 × 1.5L Joybuy listing gives a 7-day period under refrigeration. The directions differ by product.
