Travellers packing one meal
A 330ml can can sit alongside a sandwich, wrap or snack without leaving a large bottle to carry after the meal. If it comes from a multipack, you still need somewhere to keep the remaining cans.
Who is choosing a drink for the journey?
The useful starting point is whether you need one serving, want to compare sugars or need an explicitly caffeine-free drink.
Shoppers comparing sugars
Check the “of which sugars” figure for the exact drink and serving size. Tesco Groceries lists 0g per 330ml for several cola and lemon-lime examples, but its Fanta Orange Zero listing gives a different figure.
Travellers avoiding caffeine
Look for an explicit caffeine-free label rather than relying on a zero-sugar name. Tesco Groceries labels Fanta Orange Zero and Pepsi MAX No Caffeine No Sugar as caffeine free; the Pepsi option is listed as an eight-can pack.
What should you check before choosing?
Match the drink to the meal and journey first, then compare the label of the exact flavour and pack you intend to carry.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars and serving | Read “of which sugars” for the stated serving, not just the front-of-pack name. Tesco Groceries lists 0g per 330ml for Coca-Cola Zero Sugar and Pepsi MAX, but 1.3g per 330ml for Fanta Orange Zero. | I want to know the sugars figure for the can I will drink with my meal, rather than assume similar-sounding products have identical nutrition. |
| Caffeine | Check for an explicit caffeine-free statement on the exact variant. Tesco Groceries labels Fanta Orange Zero and Pepsi MAX No Caffeine No Sugar caffeine free; its regular Pepsi MAX ingredient excerpt includes caffeine. | If I am avoiding caffeine, a zero-sugar label alone does not answer my question. For pregnancy, the NHS advises no more than 200mg of caffeine a day from all sources. |
| Pack format | Compare the can size with the number of cans supplied. A 330ml can is one defined serving, but an eight- or twelve-can pack means packing one separately and keeping the rest. | For a single journey, I would rather carry one can than an unfinished large bottle; if I buy a multipack, I need a use for the remaining cans. |
| Flavour | Choose the stated cola, lemon-lime, orange or other flavour, then check that particular variant’s sugars and caffeine information. A flavour or brand family does not establish those figures. | I want something I will enjoy with my food, without treating every non-cola or fruit-flavoured option as nutritionally alike. |
| Acidity | Do not use a 0g sugars figure as a measure of acidity. NHS Lancashire and South Cumbria Integrated Care Board explains that even diet fizzy drinks are acidic and can wear away enamel. | If I expect to drink throughout a long journey, I can have the fizzy drink with my meal and pack water for later. |
What is easy to overlook?
-
Assuming similar zero-style names mean identical sugars
Tesco Groceries lists 1.3g sugars per 330ml for Fanta Orange Zero, compared with 0g per 330ml for its Coca-Cola Zero Sugar and Pepsi MAX examples.
Compare “of which sugars” on the exact flavour and pack rather than relying on the product family name.
-
Reading zero sugar as caffeine free
Tesco Groceries lists caffeine in regular Pepsi MAX’s ingredients, while Pepsi MAX No Caffeine No Sugar and Fanta Orange Zero are labelled caffeine free.
If caffeine matters to you, check the exact variant for an explicit caffeine-free statement.
-
Sipping a diet fizzy drink for the whole journey
NHS Lancashire and South Cumbria Integrated Care Board notes that diet fizzy drinks remain acidic and can wear away enamel.
Consider having the fizzy drink with your food and carrying water if you will want another drink later.
-
Buying several cans when you need one
Tesco Groceries lists Pepsi MAX No Caffeine No Sugar as an eight-can pack, while its Fanta Orange Zero example is an individual 330ml can.
For a one-off journey, check the pack quantity before choosing; a multipack is more practical if you can keep and use the other cans.
A multipack also leaves you with extra cans to carry home or store.
Which brand references help with comparison?
These product-specific retailer listings illustrate why the variant and nutrition panel matter more than the brand name alone.
Coca-Cola
Tesco Groceries lists Coca-Cola Zero Sugar as a 330ml cola can.
- The listed can contains 0g sugars and 1 kcal.
- Check the exact variant if you need a caffeine-free drink; zero sugar does not establish caffeine status.
Pepsi
Tesco Groceries lists regular Pepsi MAX and a distinct Pepsi MAX No Caffeine No Sugar variant.
- Both listings state 0g sugars per 330ml; the No Caffeine variant is explicitly labelled caffeine free.
- The listed caffeine-free variant comes as eight cans, while regular Pepsi MAX lists caffeine among its ingredients.
Sprite
Sprite Zero Sugar offers a lemon-lime alternative to cola in Tesco Groceries’ eight-can, 330ml-per-can listing.
- The listing states 0g sugars per 330ml.
- Zero sugar does not remove the acidity consideration for fizzy drinks identified by NHS Lancashire and South Cumbria Integrated Care Board.
Fanta
Tesco Groceries lists Fanta Orange Zero as a caffeine-free orange drink in a 330ml can.
- The listing explicitly identifies the orange variant as caffeine free.
- Its nutrition panel lists 1.3g sugars per 330ml, so check the figure rather than assuming the name means 0g.
Tesco
Tesco Groceries provides the product-level pack and nutrition listings used in these examples; it is a retailer reference, not a single drink formulation.
- Its listings allow comparisons by the stated variant and serving size.
- Check the current product label when ingredients or dietary suitability affect your choice.

Questions about packing fizzy drinks
Should I pack a 330ml can or a large bottle with one train meal?
A 330ml can gives you a defined serving and avoids carrying a partly finished large bottle if you drink it with the meal. A bottle may suit you better if you need to reseal the drink: an opened can cannot be resealed.
Does zero sugar mean a fizzy drink is free from acidity concerns?
No. NHS Lancashire and South Cumbria Integrated Care Board says that even diet fizzy drinks are acidic and can wear away enamel. If you want a drink to sip later in the journey, consider packing water as well.
Which of the retailer-listed examples are caffeine free?
Tesco Groceries labels Fanta Orange Zero and Pepsi MAX No Caffeine No Sugar as caffeine free. Choose the exact variant and check its current label rather than assuming another drink from either brand has the same caffeine status.
Does cola count towards caffeine intake during pregnancy?
Yes. The NHS identifies cola as a possible caffeine source and advises no more than 200mg of caffeine a day during pregnancy. Consider caffeine from other food and drinks as well, and check the exact cola variant if you want a caffeine-free option.
