Hosts planning a late game night
If anyone wants to avoid caffeine, look for an explicitly caffeine-free variant. Coca-Cola GB and Pepsi UK identify caffeine-free versions separately from their regular zero-sugar colas.
Who is choosing?
Hosts choosing a branded zero-sugar cola
Coca-Cola Zero Sugar, Diet Coke, Pepsi Max and Diet Pepsi are named options to compare. Check the ingredients of the exact variant if caffeine or particular sweeteners matter to guests.
Groups sharing a bottle
A 2-litre own-label diet cola allows shared pours. Sainsbury’s and Asda each describe eight suggested 250ml servings for their listed 2-litre bottles; allow for refills when deciding how many drinks to bring.
What should you check?
Choose the caffeine option first, then check the exact cola’s sugar information, ingredients and serving format.
Caffeine-free, zero-sugar cola
Choose when: A guest avoids caffeine or you want a caffeine-free option for a late session.
Check: Regular zero-sugar versions can contain caffeine, so select the explicitly caffeine-free variant.
Regular branded diet or zero-sugar cola
Choose when: Caffeine is acceptable and guests want a particular branded cola.
Check: Sweetener ingredients differ between products; the brand name alone does not identify the formulation.
Own-label 2-litre diet cola
Choose when: Several players will pour drinks from a shared bottle.
Check: The Tesco, Sainsbury’s and Asda products described here list caffeine, so a separate option is needed for guests avoiding it.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar information | Read the nutrition panel for sugars per 100ml or per serving. Check the exact variant rather than relying on its brand or the word “diet”. | I want a cola whose stated sugar content matches what I plan to serve. |
| Caffeine | Look for an explicit caffeine-free designation. Coca-Cola GB and Pepsi UK distinguish their caffeine-free zero-sugar variants from regular versions that list caffeine. | If the game runs late or a guest avoids caffeine, I want to be able to identify the caffeine-free cans or bottles. |
| Sweeteners | Read the exact pack’s ingredient list. Coca-Cola Zero Sugar, Diet Coke and the Joybuy Pepsi Max listing identify aspartame; the cited Sainsbury’s and Asda diet colas list other sweetener blends. | A guest may need to check a particular ingredient, so I cannot treat diet colas as interchangeable. |
| Portions | Compare the can count and volume with planned pours. Sainsbury’s and Asda describe eight suggested 250ml servings from their respective 2-litre bottles. | For individual drinks I may prefer cans; for shared pours, I need to account for the number of players and possible refills. |
Common buying mistakes
-
Assuming “zero sugar” also means caffeine-free
Coca-Cola GB and Pepsi UK identify caffeine-free variants separately; their regular zero-sugar colas list caffeine.
If caffeine matters to a guest, choose a pack explicitly labelled caffeine-free and check its ingredients.
-
Assuming every diet cola uses the same sweeteners
Ingredient lists differ between the cited branded and own-label products. That distinction matters when someone needs to check a particular ingredient.
Read the exact variant’s ingredients and any relevant pack statement before serving or substituting a different cola.
-
Planning portions by bottle size alone
A shared bottle gives pours rather than separately portioned drinks, and one cola may not meet different guests’ caffeine preferences.
Use the bottle’s serving guidance to plan pours and provide a separately identified caffeine-free option if needed.

Frequently asked questions
Does zero-sugar cola automatically mean caffeine-free?
No. Coca-Cola GB and Pepsi UK distinguish their caffeine-free variants from regular zero-sugar products that list caffeine. Choose a cola explicitly labelled caffeine-free if a guest needs that option.
How many pours can I plan from a 2-litre bottle?
At 250ml per pour, a 2-litre bottle gives eight pours, matching the serving guidance on the cited Sainsbury’s and Asda diet colas. Allow more if players are likely to have refills.
What if a guest needs to check for phenylalanine?
Check the exact cola’s ingredient list and pack statement before serving it. Several of the cited branded colas contain aspartame, so do not assume another diet or zero-sugar variant has the same ingredients.
