Shared film-night hosts
A 2-litre bottle can be divided into eight 250ml glasses, as shown on several Pepsi Max, Coca-Cola and Sainsbury’s product labels. Think about how many guests want cola and what you will do with any remainder.
Who is a 2-litre bottle for?
Guests choosing by sugar content
Full-sugar and zero-sugar 2-litre colas have different nutrition labels. Compare the exact bottles on the same per-100ml or per-serving basis, and check the sweeteners in a zero-sugar option.
Guests avoiding caffeine
A zero-sugar label does not establish that a cola is caffeine-free. Pepsi Max No Caffeine No Sugar 2L is a labelled caffeine-free option; check the precise variant before buying for an evening screening.
What should you check?
Start with the sugar and caffeine labels, then match the bottle or multipack to the number of people drinking it.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar and taste | Compare sugars per 100ml or per 250ml on the exact variant. ASDA lists Coca-Cola Original Taste 2L at 27g sugars per 250ml glass and Pepsi Max 2L at 0g per 250ml; zero-sugar options use sweeteners. | We prefer the original full-sugar taste, or we would rather share a zero-sugar cola. Either way, everyone drinking it should know which variant is in the bottle. |
| Caffeine | Look for an explicit caffeine-free label, not just “zero sugar”. Sainsbury’s describes Pepsi Max No Caffeine No Sugar 2L as caffeine-free, while standard Pepsi Max contains caffeine according to Pepsi UK and ASDA. | Caffeine avoidance matters for this screening, so I need the exact bottle to say caffeine-free. |
| Servings and storage | Eight 250ml glasses use a full 2-litre bottle. Check the opened-bottle instructions: Tesco Xero Cola and the cited Sainsbury’s colas say to refrigerate after opening and use within 3 days. | Will the group finish one bottle, and can I refrigerate what is left? A multipack needs planning beyond one film night. |
| Ingredients | Read the current ingredient and allergen label for each variant, including sweeteners and caffeine. Tesco labels its Every Day Value Sugar Free Cola as containing gluten from barley malt extract; that does not describe every own-label cola. | I am open to an own-label bottle, but I want to check its own label rather than assume it matches a familiar brand. |
Mistakes to avoid
-
Assuming equal-sized bottles contain similar amounts of sugar
A 2-litre volume says nothing about sugar per glass. ASDA lists 27g sugars per 250ml for Coca-Cola Original Taste and 0g per 250ml for its Pepsi Max and Coca-Cola Zero Sugar examples.
Compare the nutrition panels on the exact variants using the same serving size.
-
Treating zero-sugar as caffeine-free
Pepsi UK lists caffeine in standard Pepsi Max, and ASDA lists caffeine flavouring in Coca-Cola Zero Sugar. A separately labelled Pepsi Max No Caffeine variant is caffeine-free.
If caffeine avoidance matters, confirm “caffeine-free” on the specific bottle rather than relying on its sugar claim.
-
Skipping the ingredient label on an own-label cola
Formulations differ: Tesco’s Every Day Value Sugar Free Cola contains barley malt extract and is labelled as containing gluten.
Check the current bottle for allergens, sweeteners and caffeine before serving it to guests.
-
Overlooking what happens after opening
Tesco Xero Cola and the cited Sainsbury’s colas instruct customers to refrigerate an opened bottle and consume it within 3 days.
Plan the number of 250ml glasses you expect to pour, then follow the chosen bottle’s storage instructions.
An unfinished bottle may go unused if the group cannot finish it within the labelled opened-life period.
Brand and own-label references

Joybuy 2-litre cola options
These Joybuy options are multipacks of 2-litre bottles for sharing. Check the pack quantity against your plans for this screening and later use.
No image available
PEPSI Regular 8 × 2L
Eight 2-litre bottles give a group more than one bottle to share. This is a regular cola option for guests accepting sugar and caffeine; consider whether the group will use the full multipack.
No image available
Coca-Cola Zero Sugar 2L × 6
Six 2-litre bottles suit plans that extend beyond one screening. This zero-sugar variant contains caffeine and sweeteners, including aspartame, and is labelled as containing a source of phenylalanine.
No image available
Diet Coke Caffeine Free 2L × 6
Six 2-litre bottles may be more than a single screening calls for. Although the product is named Caffeine Free, its accompanying information also refers to caffeine; check the exact bottle label before choosing it for someone avoiding caffeine. It contains sweeteners and a source of phenylalanine.
Common questions
How many glasses does a 2-litre cola bottle provide?
A 2-litre bottle provides eight 250ml glasses if poured evenly. Pepsi Max, Coca-Cola Original Taste and the cited Sainsbury’s colas use eight servings on their retailer labels; the number of guests served depends on how much each person drinks.
Should we choose full-sugar or zero-sugar cola?
Choose according to the group’s taste preference and the exact bottle’s sugar label. ASDA lists 27g sugars per 250ml glass for Coca-Cola Original Taste 2L and 0g per 250ml for its Pepsi Max and Coca-Cola Zero Sugar examples; the zero-sugar drinks contain sweeteners.
Can a 2-litre zero-sugar cola also be caffeine-free?
Yes: Sainsbury’s describes Pepsi Max No Caffeine No Sugar 2L as caffeine-free and lists 0g sugars per 250ml. Standard zero-sugar colas are not necessarily caffeine-free, so check the exact variant.
What should I do with cola left after the film?
Follow the chosen bottle’s opened-storage instructions. Tesco Xero Cola, Sainsbury’s Cola and Sainsbury’s Diet Cola instruct customers to refrigerate after opening and consume within 3 days.
