Choose plain sparkling water if you want a fizzy breakfast drink without sugar or calories and prefer minimal ingredients. If flavour matters, a product labelled zero sugar and zero sweeteners is another option; check its ingredients rather than assuming every flavoured water is the same, and consider drink acidity if you have dental concerns.
If you usually choose a sweetened drink with breakfast, plain sparkling water offers fizz without sugar or calories, according to the Natural Source Waters Association’s sparkling-water factsheet. Check the label when choosing a flavoured alternative.
A flavoured sparkling water labelled zero sugar and zero sweeteners may suit a preference for flavour without choosing a sweetened drink. Ingredients still vary: Sainsbury’s describes Maison Perrier Forever Lime as containing neither sugar nor sweeteners, while M&S lists a sweetener in Summer Berries Sparkling Water.
Multipacks provide bottles for repeated use, but bottle size matters if a large opened bottle would be difficult to finish within its storage guidance. Compare the pack format with how many people will drink it.
Start with whether you want plain water or flavour, then check the nutrition panel, ingredients and bottle format for the exact product.
Choose it when: you want fizz without sugar, calories or added flavour.
Bear in mind: no sugar does not settle questions about acidity; Highland Spring states a pH of 4 to 5 for its sparkling water.
Choose it when: you want a flavoured fizzy drink but do not want sugar or sweeteners in that product.
Bear in mind: flavouring makes it a different ingredient choice from plain water, even when the label says zero sugar.
Choose it when: you are comfortable with the sweetener and other ingredients listed for the particular drink.
Bear in mind: M&S Summer Berries Sparkling Water lists citric acid, flavourings, a preservative and steviol glycosides; it is not plain water.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar and energy | Read sugars and energy on the nutrition panel, using the same per-100ml basis when comparing drinks. Check the current bottle label. | I want a fizzy breakfast drink without adding sugar. Plain sparkling water contains no sugar or calories, according to the Natural Source Waters Association’s factsheet; a flavoured drink needs its own label check. |
| Ingredients | Distinguish plain carbonated water from drinks with flavourings, acids, juice or sweeteners. A zero-sugar label does not describe the full ingredient list. | Flavour appeals to me, but I want to know whether the drink also contains a sweetener. Sainsbury’s lists Maison Perrier Forever Lime as zero sugar and zero sweeteners; M&S lists steviol glycosides in Summer Berries Sparkling Water. |
| Acidity | Do not use sugar content as the only dental consideration. Highland Spring states a pH of 4 to 5 for its sparkling water; NHS guidance notes that fizzy drinks may contain acids harmful to teeth. | If I have concerns about dental erosion, I need advice suited to my circumstances and how often I drink acidic drinks, rather than assuming that zero sugar answers the question. |
| Bottle format | Compare individual bottles with larger bottles and read the opened-storage instructions for the product. M&S advises refrigerating its opened 2L Sparkling Irish Natural Mineral Water and consuming it within 3 days. | A smaller bottle may fit my breakfast routine if I drink sparkling water only occasionally; a multipack may be more convenient when several people will use it. |
Flavoured products can contain acids, flavourings, preservatives or sweeteners even when their names include “water”. M&S lists several of these ingredients in its Summer Berries Sparkling Water.
Read the ingredient list alongside the nutrition panel, and compare plain and flavoured drinks as separate choices.
NHS guidance notes that fizzy drinks may contain acids harmful to teeth. Highland Spring states that its sparkling water has a pH of 4 to 5, so a sugar-free label does not answer every acidity concern.
If you have dental erosion or have been advised to limit acidic drinks, ask your dentist about drink choice and frequency.
An opened bottle may not fit occasional breakfast use if it needs to be finished within a short period. M&S advises consuming its opened 2L Sparkling Irish Natural Mineral Water within 3 days.
Check the instructions on the bottle you intend to buy and choose a size that fits your likely use.
