Take squash or cordial and sparkling water if you want to adjust the flavour and can carry two items and mix them on the train; check that the concentrate is suitable for sparkling water. Choose a ready-to-drink fizzy drink if avoiding the extra bottle and mixing step matters more. Sparkling water is not sparkling squash, so check the exact drink’s dilution instructions, ingredients and allergens before travelling.
National Rail says passengers can bring their own food and drink on the train. If you want something fizzy with a packed meal, decide whether carrying concentrate and sparkling water is worth the mixing step, or whether one ready-to-drink bottle is more convenient.
A no-added-sugar label does not mean sweetener-free or allergen-free. ASDA lists acesulfame K, sucralose and sulphur dioxide/sulphites for Robinsons Double Strength Apple & Blackcurrant squash; check the label of the exact flavour you buy.
A cordial expressly intended for sparkling-water mixing gives you another flavour option. Waitrose describes Belvoir Lemon & Lime No Added Sugar Cordial as suitable for still or sparkling water and specifies a 1-to-6 dilution.
Decide first whether you want to mix a drink during the journey. Then compare the exact label, dilution and amount you would need to carry.
Choose it when: You want to adjust the squash strength to suit your food.
Trade-off: You need sparkling water as well as the concentrate, and must mix the drink.
Choose it when: You want a cordial flavour and its label permits sparkling-water dilution.
Trade-off: You still need a second bottle and a plan for storing any cordial left after the journey.
Choose it when: You want fizz with your meal without measuring or mixing.
Trade-off: Plain sparkling water does not give you the adjustable fruit flavour of a squash or cordial.
| Priority | What to check | Your needs |
|---|---|---|
| Ease of preparation | Is it a concentrate or ready to drink? If mixing, can you carry sparkling water too? Check the bottle closure if you plan to save some for later. | I want a drink with my train food without having to prepare it, so a ready-to-drink bottle makes more sense for this journey. |
| Flavour strength | Check that the concentrate can be mixed with sparkling water and follow its own dilution directions. ASDA specifies 1 part concentrate to 9 parts water for Robinsons Double Strength Apple & Blackcurrant; Waitrose gives 1 to 6 for Belvoir Lemon & Lime cordial. | If I want to adjust the flavour, carrying a concentrate and sparkling water is worth the extra mixing step. |
| Ingredients and allergens | Read the exact flavour’s ingredient and allergy panels. A no-added-sugar claim does not establish that a drink contains no sweeteners or allergens; compare nutrition information on the same prepared-drink basis where labels provide it. | I need to check particular ingredients before buying, rather than relying on the wording on the front of the bottle. |
| Amount to carry | Check whether you are buying one drink, a multipack or a concentrate for several uses. For cordial, read the storage and use-after-opening directions. | For one short journey, I may not want to carry a larger bottle or take home unused concentrate. |
Squash and cordial sold for dilution need sparkling water to make a fizzy drink. M&S describes mixing its squash and cordials with still or sparkling water.
Check whether the label says concentrate, cordial or ready to drink, and take a separate bottle of sparkling water if you choose to mix.

Read the ingredients and allergy information for the precise flavour and size you intend to share or drink.
A concentrate also requires water for dilution. If you only want one drink, consider whether you will use the rest after travelling.
Compare a mini concentrate with a ready-to-drink bottle, or check a larger cordial’s dilution and opened-bottle storage directions before buying.
These are examples of formats and label details to compare, not an indication that every flavour has the same ingredients or is available for your journey.
