Hosts serving mixed preferences
Offer a regular and a zero-sugar choice if both are wanted. Choose the number and size of containers for the group rather than relying on brand alone.
Who is choosing the cola?
The useful starting point is what guests will actually drink, especially when the group has different preferences about sugar or caffeine.
Hosts with guests avoiding caffeine
Look for an explicitly caffeine-free cola. A zero-sugar label does not establish that the drink is caffeine-free.
Hosts checking sweetener labels
Read the ingredient list and any phenylalanine statement on the exact pack, particularly if a guest needs to check whether it contains aspartame.
What should you check?
Decide which formulations to serve before choosing a pack format. Compare sugar figures on the same per-100ml basis, then check caffeine and ingredient labels on each option.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar | Compare sugars per 100ml on the exact products. Coca-Cola Great Britain lists Original Taste at 10.6g and Zero Sugar at 0g; Pepsi UK lists Pepsi at 4.5g and Pepsi MAX at 0g. | I want guests to be able to choose between regular and zero-sugar cola, rather than having one option chosen for the whole group. |
| Caffeine | Check for explicit No Caffeine or Zero Caffeine wording and read the ingredients. Standard Coca-Cola Zero Sugar and Pepsi MAX list caffeine or caffeine flavouring, according to their UK brand labels. | Someone coming to brunch wants to avoid caffeine, so I need a separately labelled caffeine-free drink. |
| Sweeteners | Read the current ingredients and phenylalanine statement. Coca-Cola Great Britain and Pepsi UK list aspartame in their standard zero-sugar colas; GOV.UK explains the warning wording for foods containing aspartame. | I want guests who check sweeteners to be able to see the label for the drink they are served. |
| Pack format | Check the container size, pack count and how many different colas the group wants. Confirm the supplied quantity if a listing's title and description disagree. | Individual cans would let guests take different options; if everyone wants the same cola, a sharing format may be simpler. |
Common mix-ups to avoid
-
Assuming zero sugar means caffeine-free
Standard Coca-Cola Zero Sugar and Pepsi MAX contain caffeine or caffeine flavouring, according to their UK ingredient lists. Their caffeine-free alternatives are separately labelled.
If a guest wants to avoid caffeine, check that the specific drink says No Caffeine or Zero Caffeine before serving it.
-
Choosing regular cola without comparing labels
Regular colas do not all have the same sugar figure: Coca-Cola Great Britain lists 10.6g sugars per 100ml for Original Taste, while Pepsi UK lists 4.5g for Pepsi.
Decide whether to offer regular cola, zero-sugar cola or both, then compare the products' per-100ml labels.
-
Treating zero-sugar formulas as interchangeable
Coca-Cola Zero Sugar and Pepsi MAX list sweeteners including aspartame and carry a phenylalanine statement. A guest checking ingredients needs the information for the particular drink on the table.
Keep the current pack available to read, and check its ingredients and warnings before serving.

Questions before serving
Does zero-sugar cola automatically mean caffeine-free?
No. Coca-Cola Great Britain lists caffeine flavouring in standard Coca-Cola Zero Sugar, and Pepsi UK lists caffeine in Pepsi MAX. For a caffeine-free choice, check that the specific product is explicitly labelled Zero Caffeine or No Caffeine.
Why do some zero-sugar colas mention phenylalanine?
Coca-Cola Zero Sugar and Pepsi MAX list aspartame and state that they contain a source of phenylalanine. GOV.UK sets out the warning wording for foods containing aspartame; read the statement on the exact pack if it matters to a guest.
Is an older online listing enough to check the ingredients?
Use the current product page when shopping and check the pack before serving. The pack identifies the ingredients and warnings for the drink you actually have, which matters when choosing between similarly named variants.
Where can I check which sweeteners a cola contains?
Read the ingredient list on the specific pack. GOV.UK guidance says manufacturers must provide information about food additives in ingredient lists; a zero-sugar description alone does not identify the drink's complete formula.
