Students swapping a sugary fizzy drink
If you want fizz with a snack but are watching sugars, compare the nutrition panel per 100ml or 100g. Plain sparkling water and flavoured drinks can have different ingredient lists.
Who is choosing?
The useful starting point is whether you want plain fizz, fruit flavour without sweeteners, or bottles to keep at home.
Flavour seekers avoiding sweeteners
If plain water does not appeal, look for both the sugar figure and the sweetener declaration. A fruit flavour or a no-added-sugar label alone does not answer both questions.
Households stocking up for study sessions
For drinks kept at home, compare bottle size, the number of bottles and storage directions after opening. Smaller bottles may be easier to take to a desk; larger bottles need somewhere to be kept.
What should you check?
Choose the type of drink first, then check the particular product’s nutrition panel, ingredients and pack format.
| Priority | What to check | Your needs |
|---|---|---|
| Total sugars | Read “of which sugars” per 100ml or 100g, keeping the units in mind. Check the ingredients for fruit juice or concentrate rather than treating “no added sugar” as sugar-free. | I want fizz with my snacks without overlooking sugars in the drink. Marks & Spencer lists 7.3g sugars per 100g for its no-added-sugar Pineapple & Passion Fruit sparkling drink, which contains apple juice from concentrate. |
| Sweeteners and flavour | Check the full ingredients list if you want to avoid sweeteners. Tesco lists sucralose in Summer Fruits sparkling flavoured water; Marks & Spencer lists steviol glycosides in Summer Berries. | Fruit flavour matters to me, but I also want to know how the drink is sweetened. Sainsbury’s lists San Pellegrino Essenza Tangerine & Strawberry as having no sweetener and less than 0.1g sugars per 100ml. |
| Plain water and fizz | Distinguish plain sparkling mineral or spring water from flavoured drinks. If acidity matters to you, check the specific drink rather than assuming sparkling and still water are identical. | I would rather have an unflavoured drink at my desk. The NHS suggests trying sparkling water if you dislike the taste of plain water; Highland Spring states that its sparkling water has a pH of 4 to 5 because carbon dioxide is added. |
| Pack format | Compare bottle or can size, the number in the pack and directions for storing an opened bottle. Check the format on the product page before ordering. | For home revision, I may prefer bottles kept in the kitchen; for a short snack break, an individual bottle or can is easier to set beside my notes. |
Common buying mistakes
-
Reading “no added sugar” as “no sugar”
Fruit ingredients can still contribute sugars. Marks & Spencer lists 7.3g sugars per 100g for its no-added-sugar Pineapple & Passion Fruit sparkling drink.
If your priority is very little sugar, compare the total sugars figure and read the ingredients, rather than relying on the front-of-pack phrase.
-
Assuming a low-sugar flavour has no sweetener
Flavoured drinks differ: Tesco lists sucralose in Summer Fruits sparkling flavoured water, while Marks & Spencer lists steviol glycosides in Summer Berries.
Decide whether you want to avoid sugars, sweeteners or both, and check the ingredients of the exact flavour you choose.
-
Choosing a bottle size without considering where you will drink it
A large bottle and a small individual serving fit different revision routines, particularly if you move between home and another study space.
Check the number and size of bottles, and any storage directions after opening, before choosing a pack.
-
Choosing a specific flavour without checking availability
A drink can match your ingredient preferences yet not be available when you order. The Sainsbury’s listing reviewed for San Pellegrino Essenza Tangerine & Strawberry was marked out of stock.
Check current stock for the exact flavour and pack. If it is unavailable, compare another drink’s own nutrition panel rather than assuming a different flavour has the same formulation.
Brand and retailer references
These examples show why the exact drink and flavour matter more than a brand name alone; they do not indicate which products a retailer currently has in stock.
San Pellegrino
Its reviewed listings include plain sparkling natural mineral water and an Essenza flavoured option.
- Sainsbury’s lists Essenza Tangerine & Strawberry as containing less than 0.1g sugars per 100ml, with no sweetener.
- Check the particular flavour and current stock; the reviewed Essenza listing was marked out of stock.
Perrier
The reviewed Tesco listing is for plain sparkling natural mineral water.
- The 1L listing provides a mineral analysis for shoppers who want to compare labelled composition.
- Tesco marked that particular 1L product out of stock when reviewed; check current availability.
Highland Spring
Its sparkling range offers an unflavoured option in several bottle and pack formats.
- Highland Spring says its sparkling water contains water with added bubbles and publishes a source mineral analysis.
- The brand states a pH of 4 to 5 for its sparkling water because of carbonation; do not assume it has the same acidity as its still water.
Tesco
The reviewed Tesco listings include large packs of plain sparkling mineral water and flavoured sparkling water.
- Its plain sparkling mineral water is listed in a 6 × 2L pack, a format to consider for home use.
- Tesco Summer Fruits lists 0.2g sugars per 100ml and contains sucralose, so it does not meet a no-sweetener preference.
Sainsbury’s
The reviewed listings cover both plain San Pellegrino and a flavoured San Pellegrino Essenza multipack.
- The Essenza Tangerine & Strawberry listing gives ingredients and a per-100ml nutrition panel for checking sugar and sweetener preferences.
- That Essenza listing was marked out of stock when reviewed; check the exact product before planning around it.
M&S
Its reviewed range spans plain and flavoured sparkling waters with different formulations.
- M&S lists less than 0.1g sugars per 100g for Summer Berries sparkling water.
- Summer Berries contains steviol glycosides, while its no-added-sugar Pineapple & Passion Fruit drink lists 7.3g sugars per 100g. Check each label separately.

Questions about revision drinks
Can plain sparkling water be a regular revision drink?
Yes, if you like fizz without added flavour. The NHS suggests sparkling water for people who dislike plain water and gives 6 to 8 cups or glasses of fluid a day as a general guide; individual needs vary, including during heat, illness, pregnancy or prolonged physical activity.
Does “no added sugar” mean a sparkling drink is sugar-free?
No. Check total sugars and ingredients: Marks & Spencer’s no-added-sugar Pineapple & Passion Fruit sparkling drink contains apple juice from concentrate and lists 7.3g sugars per 100g.
How do I choose a flavoured drink without sugar or sweeteners?
Check the sugar figure and the full ingredients list for the exact flavour. For example, Sainsbury’s lists San Pellegrino Essenza Tangerine & Strawberry as having no sweetener and less than 0.1g sugars per 100ml; check current stock if you want that particular product.
Is sparkling water the same as still water in acidity?
Not necessarily. Highland Spring states that its sparkling water has a pH of 4 to 5 because carbon dioxide is added. If acidity or frequent sipping concerns you, consider your drinking pattern and compare with a still-water option rather than assuming the two drinks are identical.
