Groups sharing one bottle
Work out the number of glasses before buying. ASDA Groceries describes its Coca-Cola Original Taste 2L bottle as eight 250ml glasses; a group expecting refills will need to plan accordingly.
Who is choosing?
Shoppers comparing sugar labels
Compare the exact recipes rather than relying on the word ‘cola’. Coca-Cola GB lists 10.6g sugars per 100ml for Original Taste, Pepsi UK lists 0g for Pepsi Max, and ASDA Groceries lists less than 0.5g for ASDA Diet Cola.
Shoppers considering own-brand cola
Own-brand bottles offer different recipes to compare. ASDA Groceries lists both sugar and sweeteners in its Classic Cola, while its Diet Cola has a different sugar declaration.
What should you check?
Start with the number of servings, then compare the recipe and what you will do with any cola left after the TV night.
| Priority | What to check | Your needs |
|---|---|---|
| Servings | Check the serving size on the exact bottle and count likely refills. ASDA Groceries describes Coca-Cola Original Taste 2L as eight 250ml glasses. | I want enough for everyone without treating the whole bottle as one serving. |
| Sugar and recipe | Compare sugars per 100ml and ingredients. Coca-Cola GB lists 10.6g sugars per 100ml for Original Taste; Pepsi UK lists 0g for Pepsi Max. ASDA Groceries lists 4.5g for its Classic Cola, which contains sugar and sweeteners. | With snacks on the table, I want to choose deliberately between a sugar-containing cola and a diet or zero-sugar recipe. |
| Caffeine | Look for an explicit caffeine-free label if needed; do not infer it from ‘diet’ or ‘no sugar’. Pepsi UK lists caffeine in Pepsi Max, and ASDA Groceries lists 25mg per 250ml serving of ASDA Diet Cola. | For an evening drink, I need to know whether the particular bottle contains caffeine. |
| Leftovers | Check the opened-bottle instructions and whether the pack contains one bottle or several. ASDA Groceries says to refrigerate its Classic and Diet Cola after opening and use them within three days. | If only a few of us are watching, I would rather choose a quantity we can use as directed. |
Common buying mistakes
-
Assuming every ‘classic’ cola has the same recipe
Coca-Cola GB lists 10.6g sugars per 100ml for Original Taste, while ASDA Groceries lists 4.5g for ASDA Classic Cola, which contains both sugar and sweeteners.
Compare sugars per 100ml and the ingredient list on the bottles you are considering.
-
Reading ‘no sugar’ as ‘no caffeine’
Pepsi UK lists caffeine in Pepsi Max, and ASDA Groceries lists caffeine in ASDA Diet Cola.
If caffeine avoidance matters for your group, choose a bottle explicitly labelled caffeine-free and confirm its ingredients.
-
Choosing a large pack without planning portions
A single 2-litre bottle can provide eight 250ml glasses according to ASDA Groceries’ Coca-Cola listing. A multipack contains several such bottles, which may be more than one gathering calls for.
Count viewers and likely glasses, then check the pack quantity and instructions for storing an opened bottle.

Questions about sharing cola
How many glasses does a 2-litre bottle provide?
ASDA Groceries describes Coca-Cola Original Taste 2L as eight 250ml glasses. Use the serving size on your chosen bottle and allow for refills when deciding whether one bottle is enough.
Is no-sugar cola automatically caffeine-free?
No. Pepsi UK lists caffeine in Pepsi Max, and ASDA Groceries lists 25mg caffeine per 250ml serving of ASDA Diet Cola. Look for an explicit caffeine-free label and check the exact bottle if caffeine avoidance matters.
What should I do with an opened 2-litre bottle?

Why compare sugars per serving as well as per 100ml?
The per-100ml figure helps you compare recipes, while the per-glass figure reflects the amount poured. Coca-Cola GB lists 10.6g sugars per 100ml for Original Taste, and ASDA Groceries lists 27g per 250ml glass of its 2-litre bottle.
