Small-group travellers
If you are packing drinks alongside food and luggage, count the servings you expect to need. Tesco Groceries lists six- and eight-can options as well as larger cases, so a single journey need not mean carrying 24 cans.
Who is buying for the journey?
Shoppers comparing sugar content
If cutting down on sugar matters to you, distinguish drinks labelled zero sugar or no sugar from regular versions. Check the nutrition panel for the amount of sugars in one can.
People avoiding caffeine
If you want cola without caffeine, look for the words “caffeine free”, “no caffeine” or “zero caffeine” on the exact variant. A diet or zero-sugar name alone does not answer that question.
What should you check before choosing?
Start with how many cans you can use and carry, then check the exact drink variant for sugar, caffeine and flavour.
| Priority | What to check | Your needs |
|---|---|---|
| Pack size | Count the cans and check their volume. Tesco Groceries lists six- and eight-can packs alongside 24-can cases; consider how the pack will fit with your other luggage. | For one trip, I would rather carry the servings we expect to use than take a case intended for several people or journeys. |
| Sugar | Check whether the exact variant says zero sugar or no sugar, and read the sugars figure per can. Joybuy lists 35g sugars per 330ml can for Coca-Cola Original Taste; that figure does not describe every cola. | If I am cutting down on sugar, I want to distinguish a no-sugar variant from a regular drink rather than choose by flavour name alone. |
| Caffeine | Look for an explicit caffeine-free claim on the variant and check its label. Do not treat “diet” or “zero sugar” as another way of saying “no caffeine”. | I still want a fizzy drink, but I need to know whether this particular can contains caffeine. |
| Flavour and label | Choose between cola, lemon-and-lime and orange by the exact product name. Check ingredients, allergen information and any relevant label notices on the can. | A flavour the group wants matters, but I also need the exact variant to meet any ingredient requirements. |
Common mistakes to avoid
-
Taking a 24-can case for one short trip
A 24 × 330ml case contains 7.92 litres of drink before you account for its packaging. Carrying it alongside food and luggage may be inconvenient if only a few cans will be used.
Count the travellers and likely servings first. Keep the larger case for a group, more than one journey or a trip where you can carry and store it comfortably.
-
Reading “zero sugar” as “caffeine free”
Tesco Groceries lists separately named zero-sugar and zero-caffeine cola variants. The sugar wording does not establish the caffeine content.
When avoiding caffeine, choose a variant explicitly labelled caffeine free, no caffeine or zero caffeine, and check the can you are buying.
-
Choosing regular cola without reading the sugars figure
Sugar content is specific to the drink and serving size. Joybuy lists 35g sugars per 330ml can for Coca-Cola Original Taste; NHS guidance advises adults to limit free sugars to 30g a day.
If cutting down on sugar matters to you, compare the nutrition panels per can and consider an explicitly labelled no-sugar variant.
Brand and flavour references
These named variants illustrate choices in pack size and flavour; check the exact can rather than assuming every drink from a brand has the same ingredients.
Coca-Cola
Tesco Groceries lists Coca-Cola Zero Sugar and Coca-Cola Zero Sugar Zero Caffeine in 24 × 330ml packs. Joybuy lists a regular Coca-Cola Original Taste case in the same can format.
- The separately named zero-caffeine variant makes the caffeine distinction clear.
- Joybuy lists 35g sugars per 330ml can and caffeine for the regular Original Taste variant; those details should not be applied to the zero-sugar variants.
Pepsi
Tesco Groceries lists Pepsi Max No Sugar in a 24 × 330ml case. The Joybuy options below also include a separately named caffeine-free Pepsi Max variant.
- The variant names help distinguish a no-sugar choice from one specifically labelled caffeine free.
- Check the caffeine wording on the exact pack; “No Sugar” alone is not a caffeine-free claim.
Sprite
Tesco Groceries lists Sprite Zero Sugar in an 8 × 330ml lemon-and-lime multipack.
- The eight-can format offers individual servings without committing to a 24-can case.
- If caffeine or an ingredient matters to you, check the exact product label rather than inferring it from “Zero Sugar”.
Fanta
Tesco Groceries lists Fanta Zero Orange in an 8 × 330ml pack for shoppers choosing an orange-flavoured drink rather than cola.
- The product name identifies both the flavour and zero-sugar variant.
- Check the label of the exact orange drink when comparing ingredients or nutrition.
Dr Pepper
Tesco Groceries lists Dr Pepper Zero in an 8 × 330ml pack.
- It provides another named zero-sugar flavour in an eight-can format.
- The zero-sugar name does not establish whether the exact variant meets a caffeine requirement.
Tesco
Tesco Groceries lists its own-label Lemon & Lime Zero cans in a 6 × 330ml pack.
- Six cans may match a journey that needs fewer servings than an eight- or 24-can pack.
- Check the exact own-label variant for its flavour, ingredients and caffeine information.
Joybuy multipack options
These cola and lemon-and-lime multipacks include eight-can options for a journey and 24-can cases for sharing or later trips. Check each variant separately if avoiding caffeine matters.

Pepsi Max No Sugar 8 × 330ml

Questions about taking fizzy drinks on a train
Can I bring fizzy-drink cans on a UK train?
Yes. National Rail says passengers may bring their own food and drink. Keep the number of cans practical for your luggage, and take your empty cans and packaging with you when you leave.
Does zero sugar mean a drink is caffeine free?
No. If avoiding caffeine matters, look for an explicit caffeine-free, no-caffeine or zero-caffeine claim on the exact drink. Tesco Groceries lists Coca-Cola Zero Sugar Zero Caffeine as a separately named variant.
How should I compare regular and no-sugar cans?
If cutting down on sugar is your aim, check the variant name and compare the sugars figure per can. Joybuy lists 35g sugars per 330ml can for regular Coca-Cola Original Taste; NHS guidance advises adults to limit free sugars to 30g a day. Do not apply one drink’s nutrition figure to another variant.
Should I check the label of a familiar drink?
Yes. Check the exact can for ingredients, allergen information, caffeine and nutrition when those details affect your choice. Similar names can identify different sugar or caffeine variants.
