For a fizzy drink alongside revision snacks, choose plain sparkling water if you want to avoid the added flavourings, juice or sweeteners found in some flavoured products. Individual 500ml bottles suit a library bag or separate study sessions; larger bottles suit a shared space at home, provided you follow the label’s instructions after opening.
If you want fizz with your snacks but not a sweetened soft drink, compare plain sparkling water with flavoured varieties by reading their ingredients. The NHS suggests sparkling water as an option for people who do not like the taste of plain water.
A sealed 500ml bottle fits a single study session more readily than a large bottle. Highland Spring lists a 500ml format, while Sainsbury’s lists a 12 × 500ml sparkling spring-water pack.
Larger bottles can serve several people without each carrying an individual portion. Check the storage instructions for the exact bottle once opened: the Tesco 6 × 2L sparkling water listing, for example, says to refrigerate it and consume it within three days.
Choose the formulation first, then a bottle size that fits where you will study. Check the exact label if you are avoiding a particular ingredient.
| Priority | What to check | Your needs |
|---|---|---|
| Plain or flavoured | Read the ingredients rather than relying on the words “sparkling water”. Sainsbury’s plain sparkling spring water lists spring water and carbon dioxide; Tesco Lemon & Lime Sparkling Water lists juice concentrate, citric acid, flavourings and sucralose. | I want fizz without added flavourings or sweeteners, so a plain variety makes the choice simpler. If I prefer flavour, I’ll check that particular bottle’s ingredients. |
| Sugar and caffeine | Check the nutrition panel for sugars per 100ml and the ingredients for sweeteners or caffeine when those details matter to you. Sanpellegrino describes its Essenza range as containing no sugars or sweeteners; that description does not apply to every flavoured water. | For an evening revision drink, I want to know what is in the exact product rather than assume every fizzy water has the same formulation. |
| Frequent sipping | Consider how often you sip fizzy drinks during a long session. Highland Spring reports a pH of 4–5 for its sparkling water; the UK government’s 2025 oral-health toolkit identifies exposure to non-bacterial acids as a factor in dental erosion. | I tend to keep a drink beside me for hours, so I want to take frequent acidic-drink exposure into account, particularly if tooth wear is already a concern. |
| Bottle size | Compare individual 500ml bottles with larger formats such as Highland Spring’s 1.5L bottle or Tesco’s 6 × 2L pack. Check whether an opened bottle needs refrigeration and when its label says to use it. | A smaller sealed bottle is easier for me to take to the library; at home, I may prefer a larger bottle to pour into a glass. |
Tesco Lemon & Lime Sparkling Water lists juice concentrate, citric acid, flavourings and sucralose. Sainsbury’s plain sparkling spring water lists spring water and carbon dioxide.
Read the ingredients on the exact bottle, particularly if you want to avoid sweeteners or added flavourings.
A 2L bottle and an individual 500ml bottle meet different carrying and serving needs. Tesco’s 6 × 2L pack is geared towards keeping bottles at home rather than taking a single portion to a study session.
Choose individual bottles for travel or separate sessions; consider larger bottles when you can store and serve them at home.
Highland Spring states that its sparkling water has a pH of 4–5. The UK government’s oral-health toolkit identifies acid exposure as relevant to dental erosion, although an individual’s tooth-wear risk cannot be judged from a drink label alone.
If you have concerns about tooth wear or sensitivity, consider how frequently you drink fizzy beverages and seek individual advice from a dental professional.
These examples show why it is worth checking the named product and pack, rather than assuming every drink from a brand has the same ingredients.
Its sparkling-water range includes 500ml and 1.5L bottles and a 6 × 1L pack, according to Highland Spring.
Sainsbury’s lists San Pellegrino sparkling natural mineral water in a 6 × 500ml pack.

Sainsbury’s lists British Bottled Sparkling Spring Water in a 12 × 500ml pack.
M&S lists Collection Sparkling Natural Mineral Water in a 750ml bottle alongside separate flavoured sparkling waters.
These plain sparkling-water formats cover individual 500ml portions and a larger pack for home revision. For a flavoured drink, compare the exact ingredients separately.

Yes, if you prefer fizz. NHS guidance says water and lower-sugar drinks count towards daily fluid intake and suggests sparkling water for people who do not like the taste of plain water. Choose it for the drink you enjoy, not for a claimed concentration benefit.
Choose plain sparkling water if you want to avoid added flavourings; Sainsbury’s plain sparkling spring water, for example, lists spring water and carbon dioxide. If you prefer flavour, check the exact ingredients: Tesco Lemon & Lime Sparkling Water lists juice concentrate, citric acid and sucralose, while Sanpellegrino describes its separate Essenza range as having no sugars or sweeteners.
Frequency is worth considering, particularly if you already have tooth-wear concerns. Highland Spring reports a pH of 4–5 for its sparkling water, and the UK government’s 2025 oral-health toolkit identifies exposure to non-bacterial acids as relevant to dental erosion. A product label cannot establish your individual risk.
Follow the instructions on that bottle. The Tesco, M&S and Sainsbury’s sparkling-water listings cited here say to refrigerate their respective products after opening and consume or use them within three days; do not assume the same period applies to every brand.
