Students revising at home
If you want a drink beside you throughout a study session, distinguish regular hydration from an occasional fizzy drink. The NHS describes water as a low-cost choice for hydration.
Who is choosing the drink?
A drink for one student at home calls for a different pack decision from refreshments for a group or a school event.
Parents buying for a group
Check how many people will share the bottle, what one glass contains and whether anyone wants to avoid caffeine. Tesco Groceries describes its Coca-Cola Original Taste 2L bottle as eight 250ml glasses, with 27g sugars in each glass.
School staff and event organisers
Check the rules for the setting before choosing refreshments for pupils. Department for Education guidance covers food and drink provided in state-funded schools in England; buying a drink for revision at home is a different situation.
What should you check?
Decide whether the drink is for regular sipping or occasional sharing, then compare the exact bottle’s serving information and ingredients.
| Priority | What to check | Your needs |
|---|---|---|
| Regular drinking | Decide whether water will be the main drink. The NHS identifies water as a low-cost choice for hydration; fizzy-drink flavour is a separate preference. | I want something to drink regularly while I revise, with fizzy drinks kept as an occasional alternative. |
| Sugar and servings | Compare the sugar figure per 100ml and per serving on the exact label. Tesco Groceries lists 27g sugars per 250ml glass for Coca-Cola Original Taste 2L and describes the bottle as eight such glasses. | Several of us may share one bottle, so I want to know what is in the glass I pour—not just the total bottle size. |
| Caffeine | Read the full product name and ingredients. Joybuy’s PEPSI Max 2L ingredient listing includes caffeine; Tesco Groceries also lists a Coca-Cola Zero Sugar Zero Caffeine 2L variant. | If caffeine is something I want to avoid during late revision, I need the exact bottle to be clearly labelled caffeine-free. |
| Pack quantity | Check whether the listing is for one 2L bottle or several, and whether the group can use the quantity ordered. | We need enough to share, but I do not want to mistake a six- or eight-bottle pack for a single bottle. |
Common buying mistakes
-
Treating a 2-litre bottle as one serving
Tesco Groceries describes Coca-Cola Original Taste 2L as eight 250ml glasses, each containing 27g sugars. Bottle size alone does not tell you what is in a poured glass.
Plan how the bottle will be shared and compare the serving and per-100ml figures on the exact drink you choose.
-
Assuming zero sugar also means no caffeine
Zero sugar and caffeine-free describe different attributes. Joybuy’s PEPSI Max 2L ingredient listing includes caffeine.
If avoiding caffeine matters, check the full name and ingredients for the exact variant rather than relying on its sugar label.
-
Using a home-shopping choice for a school event
Department for Education guidance addresses food and drink provided in state-funded schools in England. It does not make a home revision purchase a school-food decision.
For refreshments provided at school, check the rules and school policy that apply to that event before ordering.
Brand and retailer references
Compare variants within a brand as well as flavours across brands: a familiar name does not establish the sugar or caffeine content of every bottle.
Coca-Cola
Its named 2L variants give shoppers regular, zero-sugar and explicitly zero-caffeine options to compare.
- Tesco Groceries lists 27g sugars per 250ml glass for Coca-Cola Original Taste 2L and also lists Coca-Cola Zero Sugar 2L.
- Tesco Groceries lists Coca-Cola Zero Sugar Zero Caffeine 2L separately; do not assume the standard Zero Sugar variant has the same caffeine status.
Pepsi
Pepsi Max is a named no-sugar cola option in Tesco Groceries’ 2L listings.
- The listed 2L format can be compared with other bottles intended for sharing.
- Joybuy’s PEPSI Max 2L ingredient information includes caffeine, so its no-sugar name should not be read as caffeine-free.
Fanta
Fanta Zero Orange offers a named 2L fruit-flavoured alternative to the listed colas.
- Tesco Groceries lists Fanta Zero Orange Soft Drink Bottle 2L.
- Check the exact flavour’s label rather than assuming other Fanta variants have the same ingredients.
Joybuy options for sharing at home
These Joybuy multipacks contain 2L cola bottles for a shared home revision session. Check the number of bottles carefully; the Diet Coke listing also needs a label check if you are choosing it to avoid caffeine.

Questions about revision drinks
Should a 2-litre fizzy drink be the main drink during revision?
Choose water for regular hydration and consider a fizzy drink as an occasional option to share. The NHS describes water as a low-cost choice for hydration; if you buy a fizzy drink, check its sugar and caffeine information.
Does zero sugar mean caffeine-free?
No. Joybuy’s PEPSI Max 2L ingredient listing includes caffeine. If you want to avoid it, check that the exact bottle is labelled caffeine-free and read its ingredients.
How many glasses are in a 2-litre Coca-Cola Original Taste bottle?
Tesco Groceries describes its Coca-Cola Original Taste 2L bottle as eight 250ml glasses. It lists 27g sugars per 250ml glass, so compare that serving figure with the amount you plan to pour.
Do school-food rules apply to drinks bought for home revision?
The Department for Education’s school-food guidance concerns food and drink provided in state-funded schools in England, not a drink bought for revision at home. If refreshments will be provided at a school event, check the rules and school policy applicable to that setting rather than treating a home-shopping choice as permission to serve it.
