Students stocking a shared kitchen
Individual cans make portions easy to separate. If you are considering a larger bottle, think about fridge space, who will share it and whether it will be finished while it is still fizzy.
Who is this for?
Students checking the sugar declaration
If your requirement is cola with no sugars listed, compare the 'of which sugars' figure per 100ml on the exact variant rather than relying on its front-of-pack wording.
Cola drinkers avoiding caffeine
Standard zero-sugar cola can contain caffeine. Look for a separately named caffeine-free version and check its ingredients before adding it to a shared shop.
What should you check?
Start with the exact drink, then decide whether its caffeine status and pack format fit your household.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars | Read 'of which sugars' per 100ml on the exact variant. Coca-Cola GB lists 0g for Coca-Cola Zero Sugar, and Pepsi UK lists 0g for standard Pepsi MAX. | I want the nutrition panel to show 0g sugars per 100ml, not just a no-added-sugar claim on the front. |
| Caffeine | Check the variant name and ingredients. Standard Coca-Cola Zero Sugar and Pepsi MAX list caffeine; Pepsi MAX No Caffeine and Coca-Cola Zero Sugar Zero Caffeine are separately identified products. | If I am avoiding caffeine, I need the caffeine-free version rather than assuming zero sugar means no caffeine. |
| Pack format | Compare the number and size of cans with the space available. For a larger bottle, consider sharing and how quickly it is likely to be finished. | Separate cans would be useful in a shared fridge; a larger bottle only works for us if there is room and someone will finish it. |
| Ingredients and acidity | Read the sweetener and phenylalanine information on the exact pack. The NHS notes that carbonated drinks can be associated with dental erosion regardless of whether they contain sugar or sweeteners. | I need to check ingredient declarations that matter to my household, without treating zero sugar as a sign that the drink is free from other considerations. |
Common buying mistakes
-
Treating 'no added sugar' as the same as 0g sugars
The phrases answer different questions. The Advertising Standards Authority describes conditions for a 'no added sugars' claim in Great Britain; that wording is not a substitute for reading the sugar figure.
If you want no sugars listed in the drink, check 'of which sugars' per 100ml on the exact product.
-
Assuming zero sugar means caffeine-free
Coca-Cola GB and Pepsi UK list caffeine in their standard zero-sugar colas, while caffeine-free versions have distinct names.
Choose a variant explicitly marked caffeine-free and confirm its ingredients if avoiding caffeine matters to you.
-
Overlooking sweetener declarations
The listed ingredients differ between products and variants. Coca-Cola Zero Sugar and the Pepsi MAX products described by their brands include aspartame.
Check the exact pack for aspartame and phenylalanine information when those declarations matter to your household.
-
Choosing a bottle without planning where it will go
A 2-litre bottle and individual cans create different demands on shared fridge space and how the drink is served.
Choose the format your household has room for and is likely to use.
An unfinished shared bottle may lose its fizz before everyone has had some.
Brand and own-label references
These examples show why the precise variant matters; a brand name alone does not establish its sugar, caffeine or ingredient details.
Coca-Cola
Coca-Cola Zero Sugar is the standard zero-sugar option; Coca-Cola Zero Sugar Zero Caffeine is a separate variant.
- Coca-Cola GB lists 0g sugars per 100ml for Coca-Cola Zero Sugar.
- The standard version lists caffeine flavouring and sweeteners including aspartame. Check the distinct Zero Caffeine product if avoiding caffeine.
Pepsi
Pepsi UK identifies standard Pepsi MAX and Pepsi MAX No Caffeine as separate zero-sugar colas.
- Pepsi UK lists 0g sugars for both products.
- Standard Pepsi MAX lists caffeine; the No Caffeine version still lists sweeteners including aspartame.
Tesco
Tesco lists Xero Cola in a 2-litre bottle, an own-label format to consider for a shared kitchen.
- A larger bottle may suit a household with fridge space and a plan to share it.
- Check the exact bottle's current nutrition panel, ingredients and caffeine information rather than assuming they match a branded cola.

Questions about zero-sugar cola
Does 'no added sugar' mean a cola contains 0g sugars?
Not necessarily. The Advertising Standards Authority explains that a 'no added sugars' claim in Great Britain concerns what has been added for sweetening. If you want a drink with no sugars listed, check 'of which sugars' per 100ml on its nutrition panel.
Is zero-sugar cola automatically caffeine-free?
No. Coca-Cola GB lists caffeine flavouring in standard Coca-Cola Zero Sugar, and Pepsi UK lists caffeine in standard Pepsi MAX. Look for an explicitly caffeine-free variant and check the exact product's ingredients.
Can sugar-free fizzy cola still affect teeth?
Yes. The NHS says carbonated drinks are associated with dental erosion because of their acid content, regardless of whether they contain sugar or sweeteners. A 0g sugar declaration does not address that acidity.
Why check the sweeteners on a zero-sugar cola?
Sweeteners can differ by variant. Coca-Cola GB and Pepsi UK list aspartame in the zero-sugar products described here; check the exact pack's ingredient and phenylalanine declarations when those details matter to your household.
