Students sharing drinks at home
A 2-litre bottle can be poured into separate glasses during a revision session. Check sugars and caffeine independently when choosing what to share.
Who is choosing the cola?
Parents and carers buying for teenagers
Look beyond the bottle size: the nutrition panel shows sugars per 100ml, while the ingredients and other label information help you check caffeine. Plan how the opened bottle will be stored.
Staff arranging drinks at schools in England
For drinks supplied to pupils at a state-funded school, consult the Department for Education’s England school-food guidance. Its permitted-drinks list does not include cola; a household purchase for home revision is a different setting.
What should you check?
For a shared bottle, compare labels on the same per-100ml basis, check caffeine separately and decide how the two litres will be served and stored.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars | Compare sugars per 100ml on the exact bottle, then consider the amount poured. Tesco Groceries lists 10.6g per 100ml for Coca-Cola Original Taste, 4.5g for Pepsi Regular and 4.4g for Tesco Classic; Joybuy lists 0g per 100ml for its Coca-Cola Zero Sugar six-pack. | I want to see the sugar difference before choosing a bottle for repeated pours or a shared revision session. |
| Caffeine | Check the exact product’s ingredients and label information; do not infer caffeine content from its sugar claim or name. Joybuy’s listed Coca-Cola Zero Sugar six-pack contains caffeine. | If the drink is for a young person or an evening session, I need to check caffeine as well as sugars. |
| Servings and storage | Work out how many glasses you intend to pour and follow the opened-bottle instructions. The Tesco Groceries Coca-Cola 2-litre listing describes eight 250ml glasses; its Tesco Classic Cola listing says to consume that product within 3 days of opening. | A bottle to share makes sense for us, but I do not want to leave the remainder open at the desk. |
| School setting | For drinks supplied to pupils at a state-funded school in England, consult the Department for Education’s school-food guidance, dated 14 September 2026. Its permitted-drinks list does not include cola; check the school’s arrangements as well. | When arranging a school-provided revision session in England, I need to choose from the permitted drinks rather than apply a home-shopping choice. |
Common buying mistakes
-
Assuming zero sugar means no caffeine
Joybuy lists 0g sugars per 100ml for its Coca-Cola Zero Sugar 2L × 6 product, but its ingredients include caffeine. The sugar declaration cannot answer a caffeine-avoidance question.
Check both the nutrition panel and the exact bottle’s caffeine information before choosing a drink for someone who needs to avoid it.
-
Treating two litres as one serving
The Tesco Groceries Coca-Cola 2-litre listing describes eight 250ml glasses. Pouring from a large bottle without deciding on servings makes the amount less apparent.
Pour the intended amount into glasses and store the remainder according to its label.
-
Using the same rule for home and school drinks
The Department for Education’s guidance dated 14 September 2026 applies to school-food provision in England. Its permitted-drinks list does not include cola; that guidance does not describe an ordinary household purchase for home revision.
For drinks supplied to pupils at a state-funded school in England, check the Department for Education guidance and the school’s arrangements. For home use, make the choice from the particular product label and household needs.
Brand and product-line references
Coca-Cola
The checked products include a regular 2-litre bottle listed by Tesco Groceries and a Coca-Cola Zero Sugar six-pack of 2-litre bottles listed by Joybuy.
- Tesco Groceries declares 10.6g sugars per 100ml for the checked Original Taste bottle; Joybuy declares 0g per 100ml for the checked Zero Sugar multipack.
- The listed Zero Sugar product contains caffeine, and its six-bottle pack is a different purchase format from one bottle.
Pepsi
Tesco Groceries lists Pepsi Regular in a 2-litre bottle, with 4.5g sugars per 100ml.
- The per-100ml declaration gives a consistent basis for comparing this regular cola with other labelled 2-litre bottles.
- The checked regular product contains sugar, sweeteners and caffeine; it is not a zero-sugar or caffeine-free option.
Tesco
Tesco Groceries lists its Classic Cola in a 2-litre bottle and declares 4.4g sugars per 100ml.
- Its label provides a per-100ml sugar figure and instructions for the opened bottle.
- The checked product contains sugar, sweeteners and caffeine; its instructions say to consume it within 3 days of opening.
RC Cola
RC Cola International identifies RC Cola within its beverage range.
- If considering an RC Cola bottle for sharing, use the particular product’s size and label for the decision.
- Compare sugars, caffeine and pack format on the exact bottle rather than applying figures from another brand’s cola.
Joybuy 2-litre cola options
These multipacks contain 2-litre cola bottles for household sharing. Compare their sugar declarations, check caffeine on the exact product and decide whether six or eight bottles suit the session and your storage space.

Coca-Cola Zero Sugar 2L × 6
For sharing at home when avoiding sugar is the priority, Joybuy’s listing declares 0g sugars per 100ml across a six-bottle pack. It also lists caffeine, and the product safety text says it is not recommended for children. This is six 2-litre bottles, not a single-bottle purchase.
No image available
Diet Coke Caffeine Free 2L × 6
Joybuy’s nutrition panel declares 0g sugars per 100ml, and the pack contains six 2-litre bottles. Despite the product name, its product information gives conflicting caffeine statements; check the exact bottle label before relying on it for caffeine avoidance. Allow space for the full multipack.

Pepsi Regular 8 × 2L
For a household choosing regular cola in a larger sharing pack, Joybuy’s listing describes eight 2-litre bottles and declares 4.5g sugars per 100ml. It also lists sweeteners and caffeine, so it does not meet a zero-sugar or caffeine-avoidance preference. Consider the total quantity before choosing this pack.
Questions about revision-session cola
Does zero-sugar cola mean caffeine-free?
No. Joybuy’s Coca-Cola Zero Sugar 2L × 6 listing declares 0g sugars per 100ml but lists caffeine. If avoiding caffeine matters, check the exact bottle’s label rather than relying on its sugar declaration.
Can a state-funded school in England supply cola at a revision session?
Cola is not on the permitted-drinks list in the Department for Education’s England school-food guidance dated 14 September 2026. For drinks supplied to pupils at school, check that guidance and the school’s arrangements; do not apply this England-specific conclusion to other UK nations or to a family’s home purchase.
How do I compare regular 2-litre colas?
Start with sugars per 100ml on each exact product, then check sweeteners, caffeine and the intended serving size. Tesco Groceries declares 4.4g per 100ml for Tesco Classic Cola, 4.5g for Pepsi Regular and 10.6g for Coca-Cola Original Taste in the checked 2-litre listings; those figures describe sugars, not overall suitability.
What should I do with an opened 2-litre bottle?
Follow the storage and use instructions on that bottle. For example, the Tesco Groceries listing for Tesco Classic Cola says to keep it cool and out of sunlight and consume it within 3 days of opening; instructions for another cola may differ.
