Daily office lunch packers
If you take one drink alongside your lunch, an individual 500ml bottle is a practical starting point. Highland Spring offers that size, and Tesco lists several 500ml multipacks.
Who is this for?
People switching from sugary fizzy drinks
If avoiding added sugars is your reason for switching, distinguish plain water from flavoured sparkling drinks by reading the exact label. The NHS suggests water or sugar-free or no-added-sugar drinks instead of sugary fizzy drinks.
Frequent fizzy-drink drinkers with dental concerns
Sugar content is not the only consideration when you regularly sip something fizzy. Northumbria Healthcare NHS Foundation Trust says sugar-free fizz remains acidic and can contribute to tooth erosion.
What should you check?
Choose a portion you can carry and finish with lunch, then check the drink itself: plain water and flavoured sparkling products need not have the same ingredients.
| Priority | What to check | Your needs |
|---|---|---|
| Portion size | Check the volume of each bottle, not just the total pack volume. Compare an individual 500ml bottle with larger bottles if you will carry only one lunch drink. | I want a bottle that fits beside my lunch and that I expect to finish with the meal. |
| Ingredients | Read the ingredients and nutrition panel for juice, sugars and sweeteners. Check the exact flavour: a claim about one range does not cover every flavoured drink. | If I am switching from a sugary fizzy drink, I want to know what is in this particular bottle. |
| Pack and storage | Check how many individual bottles the pack contains and where you will keep them. A larger bottle may suit a shared lunch or a desk fridge instead. | For regular packed lunches, I would rather set aside one bottle at a time than carry a large bottle each day. |
| Water style | Check whether the product is plain spring or mineral water, and consult its mineral information if that affects your choice. Do not assume different waters have the same taste. | When drinking it with lunch, I care about whether I enjoy the particular water’s flavour and carbonation. |
| Acidity | Consider how often you drink fizzy beverages, particularly if dental erosion concerns you. Northumbria Healthcare NHS Foundation Trust notes that sugar-free fizz can still contribute to tooth erosion. | If I sip fizzy drinks frequently, I want to account for acidity as well as sugar and ask a dental professional about personal concerns. |
What can catch you out?

Assuming every sparkling drink is plain water
A flavoured sparkling product may contain juice, sugars or sweeteners, so its ingredients may differ from those of plain sparkling water.
Read the ingredients and nutrition panel of the exact product, especially if avoiding sugars or sweeteners is important to you.
-
Choosing a large bottle for a one-person commute
A 1L or 1.5L bottle takes more room in a lunch bag than an individual 500ml bottle and may be more than you want with one meal.
Start with an individual bottle for a packed lunch; consider a larger format if you can keep it at work or plan to share it.
-
Overlooking acidity because a drink is sugar-free
According to Northumbria Healthcare NHS Foundation Trust, sugar-free fizz remains acidic and can contribute to tooth erosion.
If you are concerned about dental erosion or sip fizzy drinks frequently, discuss your circumstances with a dental professional.

Chi Forest White Peach Sparkling Water 480ml × 3

Questions about choosing sparkling water
What bottle size works for one office packed lunch?
A 500ml bottle is a practical starting point for one drink with lunch; Highland Spring offers this size, and Tesco lists several 500ml multipacks. A larger bottle may suit you if you can keep it at work or plan to share it.
Is flavoured sparkling water always free from sugar?
No. Read the exact ingredients and nutrition panel, because flavoured sparkling products differ. S.Pellegrino describes its Essenza range as having no sugars or sweeteners and zero calories, but that description does not apply to every flavoured drink.
Does sugar-free sparkling water still matter for teeth?
Yes, acidity can still matter. Highland Spring reports a pH of 4–5 for its sparkling water, and Northumbria Healthcare NHS Foundation Trust says sugar-free fizz can contribute to tooth erosion. Ask a dental professional about your own concerns, particularly if you drink fizzy beverages frequently.
How should I keep an opened bottle?
Follow the instructions on the bottle you buy. For example, the Joybuy listing for S.Pellegrino 1L sparkling water says to refrigerate it after opening and consume it within a reasonable time; instructions for another product may differ.
