Colleagues sharing lunch drinks
One bottle can serve a group without everyone bringing a separate drink. Tesco Groceries describes a 2L Coca-Cola bottle as eight 250ml glasses; bring cups and consider where the bottle will be kept during lunch.
Who is a 2-litre bottle for?
The format is most useful when the number of drinkers and the plan for an opened bottle are clear.
People comparing sugar per glass
Cola and fruit-flavoured options have different labelled sugar values. Compare the nutrition panel for the amount colleagues are likely to pour, rather than treating every drink labelled zero or diet as identical.
Shoppers planning drinks for several lunches
A pack of 2-litre bottles may suit repeated group lunches, but six bottles require more carrying and storage space than one shared bottle.
What should you check?
Start with how many people will drink it, then compare a planned serving and the ingredients on the exact bottle.
| Priority | What to check | Your needs |
|---|---|---|
| Portions | Count the drinkers and planned glasses. Tesco Groceries describes a 2L Coca-Cola bottle as eight 250ml glasses; decide how an opened bottle will be stored or taken home. | We are sharing one bottle at lunch. If it is just for me, I would rather consider a smaller drink than carry the remaining bottle. |
| Sugar per glass | Compare the label per 100ml and per serving. Tesco Groceries lists 0g sugars per 250ml for Pepsi MAX, 1.0g for Fanta Zero Orange and 11g for Sprite; the values are not interchangeable. | I want to know what is in the glass I will pour, whether the group chooses cola or a fruit flavour. |
| Ingredients | Read the exact bottle’s ingredient list and warnings for caffeine, sweeteners and a source of phenylalanine where relevant. Do not infer caffeine status from a zero-sugar name. | Someone sharing the drink may avoid a particular ingredient, so I need a formulation everyone can check before lunch. |
| Pack size | Distinguish one 2L bottle from a pack of six 2L bottles. Plan how many bottles the group will use and where the rest can be kept. | For one office lunch, I may not want to carry an entire six-bottle pack. |
Common buying mistakes

Treating 2 litres as one lunch serving
Tesco Groceries describes a 2L Coca-Cola bottle as eight 250ml glasses. Without a sharing plan, much of an opened bottle may need to be carried or stored afterwards.
Bring a 2-litre bottle for a group, or choose a smaller format when only one person will drink it.
-
Assuming zero and low-sugar names mean the same value
Tesco Groceries lists 0g sugars per 250ml for Pepsi MAX, 1.0g for Fanta Zero Orange and 11g for Sprite. A flavour or front-label description does not replace the nutrition panel.
Compare sugars per 100ml and per glass on the bottles you are considering.
-
Using zero sugar as a check for every ingredient
Sugar information alone does not tell colleagues whether a drink contains caffeine or sweeteners, or carries a phenylalanine warning.
Check the ingredients and warnings on the exact bottle before choosing one drink for a mixed group.
Brand and drink references
These examples show why the flavour name, sugar value and ingredient list each matter when choosing a bottle to share.
Coca-Cola
A choice between Original Taste and Zero Sugar in the 2-litre format.
- Tesco Groceries describes the Original Taste 2L bottle as eight 250ml glasses.
- Coca-Cola Zero Sugar is a different formulation; check its current nutrition panel and ingredients rather than using the Original Taste label.
Pepsi
Pepsi MAX is a 2-litre cola option for a group seeking a zero-sugar drink.
- Tesco Groceries lists eight servings per bottle and 0g sugars per 250ml for Pepsi MAX 2L.
- Check the exact bottle’s ingredients and warnings for anyone with a formulation-specific requirement.
Sprite
A lemon-lime alternative for colleagues who do not want cola.
- Sprite is listed in a 2-litre bottle by Tesco Groceries.
- Its listed 11g sugars per 250ml differs from the 0g value listed for Pepsi MAX.
Fanta
Fanta Zero Orange offers an orange-flavoured 2-litre option.
- Its flavour offers the group an alternative to cola.
- Tesco Groceries lists 1.0g sugars per 250ml for Fanta Zero Orange, so do not assume its value matches a cola labelled 0g.
Dr Pepper
A different fizzy-drink flavour available in a 2-litre bottle.
- It offers another flavour for a group that does not want a standard cola or lemon-lime drink.
- Tesco Groceries lists 11g sugars per 250ml for Dr Pepper 2L; check the full label before sharing.
Tesco
Tesco Diet Cola is an own-brand 2-litre cola option.
- The 2-litre format can be considered for a planned group lunch.
- Tesco Groceries instructs buyers to consume Tesco Diet Cola within three days after opening; follow the instructions on the bottle purchased.

Coca-Cola Zero Sugar 2L × 6
Six 2-litre bottles could cover several shared office lunches. Plan how to carry and chill the pack, and check the bottle’s ingredients and warnings for everyone who will share it.
No image available
Diet Coke Caffeine Free 2L × 6
This pack contains six 2-litre bottles, so consider storage and how many lunches the group will share. The variant name says Caffeine Free, but its product information also mentions caffeine. If avoiding caffeine matters, confirm the current bottle label before choosing it.
Questions about sharing a bottle
Is a 2-litre bottle suitable for one office packed lunch?
It is more practical as a planned shared drink than as one person’s lunch serving. Tesco Groceries describes a 2L Coca-Cola bottle as eight 250ml glasses; if you are drinking alone, consider a smaller format or plan what to do with the remainder.
Do all zero-named fizzy drinks list the same sugar value?
No. Tesco Groceries lists 0g sugars per 250ml for Pepsi MAX 2L but 1.0g per 250ml for Fanta Zero Orange 2L. Compare the current nutrition panels using the same serving size.
Does zero sugar mean caffeine-free?
No: a sugar description does not establish caffeine content. If a colleague avoids caffeine, check the exact bottle’s ingredient list and do not rely on the zero-sugar wording.
How long can an opened 2-litre bottle be kept?
Follow the instructions for the drink purchased. Tesco Groceries says to consume Tesco Diet Cola 2L within three days of opening; that instruction should not be applied automatically to other bottles.
What should colleagues check before sharing a drink?
Check the exact bottle’s ingredients, warnings, nutrition information and storage instructions against the group’s needs. UK government food-labelling guidance identifies ingredients, including allergens, volume and date marking among the information provided on pre-packed products.
