Families sharing snacks at home
A 2-litre bottle can be poured into eight 250ml glasses. Comparing labels at that serving size helps when several people will share it over the holidays.
Who is choosing a shared bottle?
Households comparing sugar content
Regular and no-sugar colas have different listed sugar amounts. Check the exact variant: a no-sugar label does not tell you which sweeteners it contains or whether it has caffeine.
Households avoiding caffeine
Look for an explicit caffeine-free label. The checked ASDA and Sainsbury's diet colas contain caffeine, while Sainsbury's lists Pepsi Max No Caffeine No Sugar 2L as caffeine free.
What should you check before buying?
Settle the sugar and caffeine requirements first, then compare the exact bottles by serving size, ingredients and the quantity your household can use.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar per serving | Compare sugars at the same serving size. ASDA Groceries lists 27g per 250ml for Coca-Cola Original Taste 2L; Sainsbury's lists 0g per 250ml for Pepsi Max No Caffeine No Sugar 2L. | I want to know what is in the glass I plan to pour, rather than comparing bottles by name alone. |
| Caffeine | Check for an explicit caffeine-free claim and read the ingredients. ASDA Groceries lists 25mg of caffeine per 250ml for ASDA Diet Cola; Sainsbury's identifies caffeine in its Diet Cola ingredients. | If our household avoids caffeine, I cannot treat “diet” or “zero sugar” as a substitute for “caffeine free”. |
| Sweeteners and warnings | Read the sweetener list and any phenylalanine warning on the exact bottle. Sainsbury's lists a source-of-phenylalanine warning for Pepsi Max No Caffeine No Sugar 2L. | Someone in my household may need to check a particular ingredient or follow individual dietary advice. |
| Bottle quantity | Check whether the listing is for one 2-litre bottle or a multipack. A single 2-litre bottle holds eight 250ml portions; consider how many bottles you expect to open. | For snacks shared across several days, I want a quantity that fits our plans and storage space. |
What is easy to overlook?
-
Assuming diet cola is caffeine free
The checked ASDA and Sainsbury's diet colas contain caffeine. A sugar claim alone therefore cannot answer a caffeine-avoidance question.
Choose a bottle explicitly labelled caffeine free if that distinction matters, and check its current ingredients.
-
Comparing bottle size without comparing a glass
Two 2-litre colas can have different sugar amounts per 250ml. ASDA Groceries lists 27g per 250ml for Coca-Cola Original Taste 2L, while Sainsbury's lists 0g for the same serving of Pepsi Max No Caffeine No Sugar 2L.
Compare equivalent serving sizes and think about how many glasses are likely to be poured.

Confusing home snacks with school provision
The Department for Education describes school food standards for food and drink provided to pupils on school premises in state-funded schools. That is a different setting from buying snacks for home during the holidays.
If a drink is being supplied through a school, check the requirements for that setting rather than applying a home-shopping choice to school provision.
Which brands and ranges are relevant?
Coca-Cola
A reference point if your household specifically wants Coca-Cola Original Taste or is comparing it with a zero-sugar variant.
- Coca-Cola GB lists 10.6g sugars per 100ml for Original Taste; ASDA Groceries lists 27g per 250ml for its 2-litre bottle.
- Original Taste contains caffeine. Check the exact label rather than carrying its nutrition figures over to another Coca-Cola variant.
Pepsi
Includes regular cola and a separately labelled no-sugar, caffeine-free 2-litre option.
- Sainsbury's lists Pepsi Max No Caffeine No Sugar 2L as caffeine free, with 0g sugars per 250ml.
- That product carries a source-of-phenylalanine warning. Pepsi UK lists 4.5g sugars per 100ml for regular Pepsi, so the variants should not be treated as interchangeable.
ASDA
Its own-label diet and classic 2-litre colas offer two different sugar profiles to compare.
- ASDA Groceries lists under 0.5g sugars per 250ml for Diet Cola and 11g per 250ml for Classic Cola.
- ASDA lists caffeine in both checked products, including 25mg per 250ml in Diet Cola. Check the current bottle for its ingredients.
Sainsbury's
Its own-label Diet Cola 2L is another diet variant to compare by the nutrition and ingredients panels.
- Sainsbury's lists under 0.5g sugars per 250ml for its Diet Cola 2L.
- Its ingredients list includes caffeine-containing flavourings and the sweeteners acesulfame K and sucralose; it is not a caffeine-free alternative.
Tesco
Tesco Groceries lists own-label Classic, Xero, Diet and Caffeine Free Diet colas in 2-litre formats.
- The separately named caffeine-free variant gives shoppers a specific label to look for when comparing Tesco bottles.
- Check the individual bottle's current nutrition and ingredients panel before choosing between these variants.
Joybuy 2-litre cola options
These multipacks offer regular, zero-sugar and caffeine-free-labelled cola routes for households planning to share 2-litre bottles. Check the exact pack quantity and current label before choosing.

PEPSI Regular 8 × 2L
A regular-cola option for sharing when an eight-bottle pack suits the household. Compare the current nutrition panel by serving and check caffeine information if anyone needs to avoid it.
Image unavailable
Coca-Cola Zero Sugar 2L × 6
A Zero Sugar-labelled option if a six-bottle pack fits your plans. Check the current ingredients and caffeine information; do not assume zero sugar also means caffeine free.
Image unavailable
Diet Coke Caffeine Free 2L × 6
This six-bottle pack is labelled Caffeine Free, but its listing also contains conflicting caffeine information. If avoiding caffeine matters, check the current bottle label before relying on that claim; check its sweeteners and warnings as well.
Questions about choosing cola
Do school food standards apply to cola bought for holiday snacks at home?
Buying cola for snacks at home is different from a school providing drinks to pupils. The Department for Education describes England's school food standards in the context of food and drink provided to pupils on school premises in state-funded schools; check the applicable requirements if the drink is for school provision.
How does a 250ml glass compare with a full 2-litre bottle?
A 2-litre bottle holds eight 250ml glasses. For Coca-Cola Original Taste 2L, ASDA Groceries lists 27g sugars per glass; comparing that serving figure with other bottles is more useful than treating the whole bottle as one portion.
Does diet or zero-sugar cola mean caffeine free?
No. The checked ASDA and Sainsbury's diet colas contain caffeine. If your household needs to avoid it, look for an explicitly caffeine-free bottle and check its current label; Sainsbury's lists Pepsi Max No Caffeine No Sugar 2L as caffeine free.
What if someone needs to avoid phenylalanine?
Check the warning on the exact bottle and follow that person's clinical dietary advice. Sainsbury's lists a source-of-phenylalanine warning for Pepsi Max No Caffeine No Sugar 2L, so its no-sugar and caffeine-free labels do not settle that separate requirement.
