Budget-focused cola shoppers
If you are choosing between multipacks, compare the amount of cola in each pack and check the sugar declaration on the variant you intend to buy.
Who is this for?
Shoppers choosing a branded zero-sugar cola
Pepsi UK lists Pepsi Max at 0g sugars per 100ml, and Coca-Cola GB gives the same figure for Coca-Cola Zero Sugar. Their ingredient lists still matter if you have a preference about sweeteners or caffeine.
People avoiding caffeine
A zero-sugar label is not a caffeine-free label. Look for an explicitly caffeine-free variant and check that the pack matches the one you meant to choose.
What should you check?
Start with a pack size that suits your shop, then read the nutrition declaration and ingredients for that exact variant.
| Priority | What to check | Your needs |
|---|---|---|
| Pack format | Compare the number of cans and volume per can. Decide whether you want a smaller pack or one to keep at home. | I want an amount of cola that suits this shop, rather than choosing by the appearance of the multipack. |
| Sugar declaration | Read sugars per 100ml on the exact pack. Pepsi UK lists Pepsi Max at 0g sugars per 100ml; Coca-Cola GB lists Coca-Cola Zero Sugar at 0g sugars per 100ml. | Before choosing a cola described as zero sugar, I want to confirm what its own nutrition panel says. |
| Sweeteners | Read the ingredients and any phenylalanine statement. Pepsi UK lists aspartame and acesulfame K for Pepsi Max; Coca-Cola GB lists sweeteners for Coca-Cola Zero Sugar. | A particular ingredient may affect my choice, even when the sugars declaration reads 0g. |
| Caffeine | Check the variant name and ingredients. Pepsi UK lists caffeine in standard Pepsi Max and describes Pepsi Max No Caffeine as caffeine-free; Coca-Cola GB lists caffeine flavouring in Coca-Cola Zero Sugar. | If I am avoiding caffeine, I need an explicitly caffeine-free cola, not just a zero-sugar one. |
Label mistakes to avoid
-
Assuming zero sugar means unsweetened or caffeine-free
Pepsi UK and Coca-Cola GB list sweeteners in their standard zero-sugar colas, alongside caffeine or caffeine flavouring. A sugars figure alone will not answer either ingredient question.
Read the ingredient list and choose a variant explicitly labelled caffeine-free if that is what you need.
-
Treating “zero sugar” and “no added sugar” as the same label wording
A zero-sugar nutrition declaration does not tell you which other claim appears on the pack.
If “no added sugar” is your requirement, check that wording and the ingredients on the exact product rather than relying on a search term or category name.

Frequently asked questions
Does zero sugar mean a cola has no sweeteners?
No. Pepsi UK and Coca-Cola GB list 0g sugars per 100ml for standard Pepsi Max and Coca-Cola Zero Sugar respectively, while both product ingredient lists include sweeteners. Read the exact pack if a particular ingredient matters to you.
Does “zero sugar” mean the pack says “no added sugar”?
Not necessarily. The nutrition declaration and the wording of a label claim answer different questions. If you need a product labelled “no added sugar”, check that wording and the ingredients on the exact variant.
Which cola should I check if I avoid caffeine?
Choose a variant explicitly labelled caffeine-free, such as Pepsi Max No Caffeine. Pepsi UK lists caffeine in standard Pepsi Max, while Coca-Cola GB lists caffeine flavouring in Coca-Cola Zero Sugar, so a zero-sugar description alone is not enough.
