People sharing drinks after a session
A 2-litre bottle gives several people a drink with their snacks, or can be divided across occasions. It is eight 250ml portions; for replacing fluid lost during exercise, the NHS recommends water.
Who is a 2-litre bottle for?
Shoppers comparing sugar on the label
Several named 2-litre fizzy drinks are sold as zero-sugar variants. Compare the sugars figure per 100ml on the exact bottle, then decide how much you intend to pour.
People avoiding caffeine
Sugar and caffeine are separate checks. Tesco describes Coca-Cola Zero Sugar Zero Caffeine 2L as both sugar-free and caffeine-free, whereas the Coca-Cola Zero Sugar and Dr Pepper Zero listings identify caffeine.
What should you check?
Decide whether the drink is for the workout or for sharing with snacks afterwards, then compare the exact variant and serving size.
| Priority | What to check | Your needs |
|---|---|---|
| Workout drink | Consider whether you need a drink during exercise or a fizzy accompaniment to snacks afterwards. The NHS identifies water as the best way to replace fluid lost through physical activity. | I need something to drink during or after sweating, rather than a large bottle to share later. |
| Sugar and portions | Compare sugars per 100ml on the exact label and calculate the amount in your intended serving. A 2-litre bottle contains eight 250ml portions; Pepsi UK lists 4.5g sugars per 100ml for Pepsi Classic. | If I’m serving fizzy drinks with snacks, I want to know what is in the glass I pour, not treat the whole bottle as one serving. |
| Caffeine | Check the full variant name and ingredients. Tesco describes Coca-Cola Zero Sugar Zero Caffeine 2L as caffeine-free; the ASDA Coca-Cola Zero Sugar 2L and Tesco Dr Pepper Zero 2L listings identify caffeine. | For a caffeine-free choice, I need confirmation for the exact drink, not just the words ‘zero sugar’. |
| Pack size and label | Check whether you are ordering one bottle or a multipack, and read the current pack for ingredients and nutrition before use. | A bottle for a group is different from six 2-litre bottles; I want a quantity that fits my sharing and storage plans. |
Common buying mistakes
-
Taking a shared bottle as your main workout drink
A 2-litre bottle amounts to eight 250ml portions. For fluid lost through physical activity, the NHS identifies water as the best replacement.
Take water for the workout and choose a large fizzy bottle when you have a plan to share it with snacks afterwards.
-
Reading ‘zero sugar’ as ‘caffeine-free’
The ASDA listing for Coca-Cola Zero Sugar 2L and the Tesco listing for Dr Pepper Zero 2L identify caffeine, despite their zero-sugar names.
If avoiding caffeine matters, check the exact variant and its current pack label. Tesco describes Coca-Cola Zero Sugar Zero Caffeine 2L as caffeine-free.
-
Comparing bottles without comparing servings
Nutrition figures are often given per 100ml, while the amount poured may be larger. Pepsi UK lists 4.5g sugars per 100ml for Pepsi Classic, equivalent to 11.25g in 250ml.
Compare labels on the same per-100ml basis, then use your intended serving size to understand the amount you would drink.
Brand and drink references
These examples help distinguish specific formulations; a brand name alone does not establish a drink’s sugar or caffeine content.
Coca-Cola
Two similarly named 2-litre colas meet different caffeine needs.
- ASDA lists 0g sugars per 100ml for Coca-Cola Zero Sugar 2L; Tesco describes Coca-Cola Zero Sugar Zero Caffeine 2L as sugar-free and caffeine-free.
- The ASDA Coca-Cola Zero Sugar 2L ingredients include caffeine flavouring, so check which variant you have selected.
Sprite
Sprite Zero Sugar 2L is a lemon-lime option for shoppers comparing zero-sugar drinks.
- Tesco lists 0g sugars for Sprite Zero Sugar 2L.
- If caffeine avoidance or a particular ingredient matters, confirm it on the current pack rather than relying on the drink’s name.
Fanta
Fanta Zero Orange 2L offers an orange-flavoured alternative for sharing.
- Tesco’s listing identifies the 2-litre bottle and its no-sugar product claim.
- The same Tesco nutrition listing gives 0.4g sugars per 100ml; do not assume the claim means a literal 0g figure on the panel.
Dr Pepper
Dr Pepper Zero 2L is a distinct flavour choice where the listed sugar figure matters.
- Tesco lists 0g sugars for Dr Pepper Zero 2L.
- Its listed flavourings include caffeine, so it is not a caffeine-free choice.
Pepsi
Pepsi’s published nutrition information offers a way to compare regular and zero-sugar cola formulations.
- Pepsi UK lists 4.5g sugars per 100ml for Pepsi Classic and 0g for Pepsi Max.
- Pepsi UK lists caffeine among Pepsi Max’s flavourings. Check the exact bottle size and variant when shopping.

Questions about gym snacks and fizzy drinks
Should I take a 2-litre fizzy drink to the gym?
For a drink during exercise or to replace fluid lost through sweating, take water: the NHS identifies it as the best way to replace lost fluid. A 2-litre fizzy bottle is more suited to planned sharing with snacks after the session.
Does zero sugar mean a fizzy drink has no caffeine?
No. The ASDA listing for Coca-Cola Zero Sugar 2L and the Tesco listing for Dr Pepper Zero 2L identify caffeine. Check the exact variant; Tesco describes Coca-Cola Zero Sugar Zero Caffeine 2L as caffeine-free.
How many portions are in a 2-litre bottle?
A 2-litre bottle contains eight 250ml portions. Choose the amount you intend to pour, then use the label’s per-100ml figures to compare drinks on the same basis.
What should I check before ordering a bottle or multipack?
Check the exact variant, the number and size of bottles, and the retailer’s current listing. Read the pack for ingredients and nutrition when it arrives, particularly if caffeine or a named ingredient affects your choice.
