For a pantry drink without added sugar or sweeteners, choose plain sparkling water after checking its ingredients. If fruit flavour matters more, a no-added-sugar flavoured water may suit you, but check the sweeteners: Sainsbury's lists sucralose in its Lemon & Lime variety and both sucralose and acesulfame K in Apple & Elderflower. Choose a pack size you can store and finish after opening.
Plain sparkling spring or mineral water is a straightforward starting point if you want neither added sugar nor sweeteners. Check the ingredient list rather than assuming a flavoured drink labelled no added sugar is unsweetened.
A no-added-sugar flavoured water offers a different choice if you are happy with the sweeteners on its label. Sainsbury's lists sucralose in its Lemon & Lime sparkling water and sucralose with acesulfame K in Apple & Elderflower.
Compare total volume with the space available for unopened and chilled bottles. Highland Spring has a 6 × 1L format, while M&S lists a 3L bottle; those formats create different plans for using water after opening.
Decide whether sweeteners are acceptable first, then compare bottle sizes and the directions for storing an opened bottle.
| Priority | What to check | Your needs |
|---|---|---|
| Sweeteners | Read the ingredients as well as the no-added-sugar claim. Sainsbury's Lemon & Lime lists sucralose; its Apple & Elderflower lists sucralose and acesulfame K. | I want an unsweetened drink, not just one labelled no added sugar. Plain sparkling water is the route to consider, subject to its ingredient list. |
| Flavour | Check the exact variety and its ingredients. A brand's plain mineral water and flavoured range need not have the same formulation. | Fruit flavour matters to me, and I am willing to check which sweeteners, if any, the chosen bottle contains. |
| Pack size | Compare total litres, bottle capacity and storage space. For example, six 1L bottles and one 3L bottle provide different quantities and serving arrangements. | Will I use a larger opened bottle promptly, or would smaller bottles fit the way my household drinks sparkling water? |
| After opening | Follow the chosen bottle's refrigeration and consumption directions. M&S says to refrigerate its opened 3L Sparkling Scottish Mountain Water and consume it within 3 days. | I need a bottle size that fits in the fridge and suits how quickly we will finish it. |
| Carbonation | The NHS says carbonated drinks are associated with dental erosion because of their acid content, whether they contain sugar or sweeteners or neither. | I do not want to assume that removing sugar makes a fizzy drink equivalent to still water for my teeth. |
The two are different checks. Sainsbury's Lemon & Lime sparkling water lists sucralose, while its Apple & Elderflower variety lists sucralose and acesulfame K.
If you want to avoid sweeteners, inspect the full ingredients panel or choose a plain sparkling water whose ingredients meet that requirement.
More bottles do not necessarily mean more water: bottle capacities differ, and a pack's total volume determines how much pantry space it will occupy over time.
Compare total litres, bottle size and the current price per litre before choosing a pack.
The NHS associates carbonated drinks with dental erosion due to their acid content, regardless of sugar or sweetener content.
Keep that distinction in mind when choosing between sparkling and still water for regular drinking.
A large bottle is practical only if there is room to refrigerate it and you can use it within its stated guidance. M&S instructs shoppers to refrigerate its opened 3L sparkling water and consume it within 3 days.
Check the directions on the exact bottle and choose a capacity that fits your household's use.

No. The no-added-sugar claim concerns added sugars, not the absence of sweeteners. Sainsbury's Lemon & Lime sparkling water lists sucralose, and its Apple & Elderflower variety lists sucralose and acesulfame K. Read both the ingredients and nutrition panel on the bottle you choose.
Start with plain sparkling spring or mineral water and confirm its ingredient list. For example, Joybuy describes its Highland Spring 6 × 1L pack as natural sparkling mineral water and its San Pellegrino 6 × 0.5L pack as natural mineral water with carbon dioxide.
No. The NHS says carbonated drinks are associated with dental erosion because of their acid content, whether they contain sugar, sweeteners or neither. A no-added-sugar label does not remove that consideration.
