For individual servings with no listed sugar, consider zero-sugar cans; if caffeine matters, choose a variant explicitly labelled caffeine-free rather than relying on the words “zero sugar”. Regular-sugar drinks may suit a household that prefers their formulation, but compare sugar per serving. Choose cans for separate servings or a large bottle when several people will share it.
Multipacks provide separate servings, while a large bottle can be poured for several people. Tesco Groceries lists both 24-can cola multipacks and 2L fizzy-drink bottles; the useful format depends on how the household serves them.
Check the exact drink and serving size rather than assuming every flavour in a range has the same nutrition panel. Manufacturer information lists zero-sugar cola and lemon-and-lime variants alongside regular versions with listed sugars.
A zero-sugar label does not also mean caffeine-free. Coca-Cola GB and Pepsi UK list caffeine in some zero-sugar colas, while Pepsi Max Caffeine Free is labelled as containing no caffeine. Check each pack for sweeteners and any phenylalanine statement too.
Start with the formulation each person will drink, then choose a pack format that fits how the household serves and stores it.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar per serving | Compare sugars per 100ml and per serving on the exact variant. Pepsi UK lists 15g sugars per 330ml for Pepsi Classic and 0g per 330ml for Pepsi Max. The NHS advises adults to have no more than 30g of free sugars a day. | I want to know how a regular fizzy drink contributes to the sugar in my day, or choose a version with no listed sugar. |
| Caffeine and ingredients | Look for explicit caffeine-free wording when needed. Check the ingredients and phenylalanine statement on the exact pack: Pepsi UK lists caffeine in Pepsi Max but labels Pepsi Max Caffeine Free as having zero caffeine; both list aspartame. | Someone in my household needs a particular formulation, so “zero sugar” alone does not answer the question. |
| Acidity | Do not use sugar content as a measure of acidity. NHS Lancashire and South Cumbria oral-health guidance says carbonated diet drinks are acidic and can wear enamel. | I do not want a sugar-free label to make frequent sipping seem tooth-neutral. |
| Pack format | Check the number and size of servings: cans can be opened individually, whereas a 2L bottle is poured for sharing. Tesco Groceries lists 24 × 330ml cola packs as well as 2L fizzy-drink bottles. | For meals or visitors, I need to decide whether separate cans or a shared bottle is more practical. |
Coca-Cola GB and Pepsi UK list caffeine in Coca-Cola Zero Sugar and Pepsi Max. Both also carry a phenylalanine statement, so the broad “zero sugar” description cannot establish ingredient suitability.
Read the exact variant’s ingredient panel. If avoiding caffeine, look for an explicitly caffeine-free version and check its other ingredients separately.
Pepsi UK lists 15g sugars per 330ml for Pepsi Classic and 0g per 330ml for Pepsi Max. That difference matters when accounting for sugars across drinks and food.
Compare the nutrition panels at the same serving size before deciding which formulation to stock.
NHS Lancashire and South Cumbria oral-health guidance says even diet fizzy drinks can be acidic enough to wear enamel.
Consider how often fizzy drinks are consumed, not just whether they contain sugar. The same guidance advises waiting at least 30 minutes before brushing after eating.
Formulations differ within a brand, so use these examples to narrow your checks rather than applying one variant’s label to the whole range.

Compare the regular and zero-sugar versions of the flavours your household will drink. Coca-Cola GB lists 0g sugars per 100ml for Coca-Cola Zero Sugar and Sprite Zero, while Pepsi UK lists 0g per 330ml for Pepsi Max; check the serving size on any regular alternative before choosing.
No. Coca-Cola GB and Pepsi UK list caffeine in Coca-Cola Zero Sugar and Pepsi Max respectively. If caffeine-free is the requirement, check the exact label; Pepsi UK explicitly labels Pepsi Max Caffeine Free as having zero caffeine.
Yes. NHS Lancashire and South Cumbria oral-health guidance says carbonated diet drinks are acidic and can wear enamel even without sugar. Consider how frequently the drink is consumed rather than relying on its sugar label alone.
Check the statement on every exact pack before buying. Coca-Cola GB and Pepsi UK state that Coca-Cola Zero Sugar, Pepsi Max and Pepsi Max Caffeine Free contain a source of phenylalanine; a caffeine-free label does not remove that consideration.
Choose cans when people are likely to open separate servings at different times; consider a large bottle when drinks will be poured for several people. Check the pack’s total volume and whether the household is likely to finish an opened bottle while it is still fizzy.
