Choose plain sparkling water if you mainly want fizz alongside a portable breakfast without making a sweet drink your default. If flavour matters more, compare sugars per 100ml and the amount you will drink: a light tonic is not necessarily sugar-free, and a botanical soft drink can contribute sugars. Whichever you choose, take food as well as the drink rather than treating a mixer as breakfast.
The useful distinction is whether you need a drink that travels with food, want to compare sugars for regular use, or are choosing primarily for flavour.
A portable drink can accompany something to eat. NHS Grampian’s breakfast guidance describes a meal with a fibre-rich carbohydrate, a protein source and fruit or vegetables; the drink alone does not provide that combination.
If you want fizz most mornings, compare plain water, flavoured drinks and mixers using the exact product’s sugars per 100ml and the amount in its bottle or can. A front-label description is not a substitute for the nutrition panel.
Floral and botanical drinks offer a different choice from plain water, but flavour does not tell you the sugar content. Fentimans, for example, lists 4.2g sugars per 100ml for its Gently Sparkling Elderflower; check the serving size when deciding how often it suits you.
Start with what you will eat, then choose the type of fizz you want. Compare nutrition on the same per-100ml basis before considering the full serving.
| Priority | What to check | Your needs |
|---|---|---|
| Breakfast food | Plan food alongside the drink. NHS Grampian’s breakfast guidance describes a fibre-rich carbohydrate, a protein source and fruit or vegetables. | I need something I can eat on the way, not just a fizzy drink to carry. |
| Plain or flavoured | Decide whether plain sparkling water gives you the fizz you want. For flavour, distinguish a flavoured water or soft drink from a tonic-style mixer by checking the exact product. | Plain fizz is enough for me, or I would rather choose a specific fruit, floral or tonic flavour. |
| Sugars and serving | Compare sugars per 100ml, then account for the volume you expect to drink. Fentimans lists 4.2g sugars per 100ml for Gently Sparkling Elderflower, which it offers in 275ml and 750ml sizes. | If I buy a flavoured drink regularly, the amount in the whole bottle matters as much as the per-100ml figure. |
| Label details | Read the nutrition panel and use traffic-light labelling where it appears; also check ingredients relevant to you. A ‘light’ comparison may be against another drink in the same range, not against water. | I want a quick way to compare packs without relying on the front label. In a 2024 survey of 611 people in Northern Ireland, the Food Standards Agency and Ipsos Northern Ireland reported that 49% actively used traffic-light labelling when shopping for food; that figure does not measure breakfast-drink preferences. |
| Pack format | Check the volume of each bottle or can, the number in the pack and whether its container suits your journey. A multipack quantity is different from the serving you will take with breakfast. | A single serving needs to fit into my morning routine, while the full pack needs to be practical to keep at home. |
| Tonic flavour | Choose a tonic-style mixer for its particular flavour, not on the assumption that ‘light’ means sugar-free. Fever-Tree says its Refreshingly Light Elderflower Tonic has 47% fewer calories than its own standard Elderflower Tonic; check the exact pack for sugars, ingredients and serving size. | I specifically want an elderflower tonic rather than plain water or another flavoured fizzy drink. |
A sparkling water, mixer or soft drink is not a substitute for the food components described in NHS Grampian’s breakfast guidance.
Choose something portable to eat first, then pick the drink to go with it.
Those descriptions do not give you the same comparison as sugars and calories per 100ml. Bottle and can sizes can also differ.
Read the nutrition table for each exact product, then consider how much of the pack you will drink. Traffic-light labelling, where present, can provide another quick reference.
Floral ingredients and sugar content are separate questions. Fentimans lists 4.2g sugars per 100ml for Gently Sparkling Elderflower.
Compare the labelled sugars and serving size with the plain or flavoured sparkling drinks you are considering.
A drink’s flavour does not tell you which ingredients or precautionary allergen statements appear on its pack. The Food Standards Agency explains that precautionary allergen labelling flags allergens that could be unintentionally present.
If an ingredient or allergen is relevant to you, check the current label for the exact drink and flavour.
These brand ranges show how plain water, flavoured soft drinks and mixers differ; check individual products rather than applying a range-wide claim to every bottle.
Fever-Tree’s range includes tonics, sodas, mixers and sparkling soft drinks for shoppers looking beyond plain water.
Fentimans offers botanical and floral sparkling drinks, including Gently Sparkling Elderflower.
Britvic describes a range covering mixers, juices and cordials, alongside Aqua Libra infused sparkling water.
Tesco’s own-label listings include plain sparkling mineral water and flavoured sparkling-water options.
These options cover plain sparkling water, fruit-flavoured fizzy drinks and an elderflower drink to take alongside a portable breakfast. Compare the stated pack sizes with the serving you want to carry.

For elderflower flavour alongside breakfast, the stated drink size is 330ml. Compare the pack’s per-100ml nutrition values with the full amount you intend to drink.
A mixer can accompany breakfast, but it does not replace the food components in NHS Grampian’s breakfast guidance: a fibre-rich carbohydrate, a protein source and fruit or vegetables. Pick something portable to eat, then choose a drink to go with it.
Compare the labelled sugars per 100ml first, then account for the volume you will drink. Fentimans lists 4.2g sugars per 100ml for Gently Sparkling Elderflower, so its 275ml size contains approximately 11.55g labelled sugars based on those figures. Total sugars on a nutrition panel are not automatically the same measure as free sugars.
No such comparison follows from the word ‘light’. Fever-Tree says its Refreshingly Light Elderflower Tonic has 47% fewer calories than its own standard Elderflower Tonic; that claim does not compare its sugars with sparkling water. Read the exact drinks’ nutrition panels before choosing.
Check the current pack’s ingredient list and any precautionary allergen statement for the exact flavour you intend to drink. The Food Standards Agency explains that precautionary labelling flags regulated allergens that could be unintentionally present; do not assume another flavour has the same statement.
