For festival food, choose the exact cola variant around your guests’ needs: check its sugar value, then decide whether flavour preference or caffeine avoidance narrows the choice. Coca-Cola describes Zero Sugar as closer to its original cola flavour and Diet Coke as lighter; standard diet and zero-sugar products are not automatically caffeine-free, so check the pack’s caffeine and sweetener information before serving.
If you are serving cola with shared food, check the sugar figure per 100ml on the exact variant. Flavour is a separate choice: Coca-Cola describes its Zero Sugar and Diet Coke recipes as having different taste profiles.
For guests who avoid caffeine, choose a variant explicitly labelled caffeine-free or no caffeine. Standard Pepsi Max and Diet Coke list caffeine, while separately named no-caffeine variants are available.
Sweetener and phenylalanine statements matter when choosing for someone with phenylketonuria (PKU). The NHS says aspartame is unsuitable for people with PKU, so read the current pack rather than relying on its diet or zero-sugar name.
Start with the exact variant’s nutrition and ingredient information, then check whether the container size and pack quantity work for serving food.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar content | Read sugars per 100ml on the exact product. Pepsi UK lists 0g for Pepsi Max, and Tesco Groceries lists 0g for Coca-Cola Zero Sugar; Coca-Cola Great Britain lists 10.6g per 100ml for Coca-Cola Original Taste. | I want a cola with a stated sugar value that fits what I am buying for the table, rather than choosing by the colour or name of the pack. |
| Caffeine | Check the full variant name and ingredients. Pepsi UK lists caffeine in standard Pepsi Max; Pepsi Max No Caffeine is a distinct product. Coca-Cola Great Britain likewise identifies a separate Diet Coke No Caffeine variant. | For an evening gathering or guests avoiding caffeine, I need a clearly labelled no-caffeine option, not just a diet cola. |
| Sweeteners | Read the current ingredients and any phenylalanine statement. Pepsi UK lists aspartame and a phenylalanine statement for standard Pepsi Max; the NHS says aspartame is unsuitable for people with PKU. | If someone I am serving has PKU, the sweetener information matters independently of whether the drink contains sugar. |
| Serving format | Compare the number of containers, volume per container and total volume. A 24 x 330ml pack contains 7.92 litres; check how many cans you can serve and chill. | I would like individual cans for sharing, but I need to know whether the pack has enough for the guests and space available. |
Standard Pepsi Max and Diet Coke list caffeine, while their no-caffeine alternatives are separate variants. Picking the wrong name on a similar-looking pack can defeat a caffeine-avoidance requirement.
Look for an explicit no-caffeine or caffeine-free label and check the ingredients on the pack you buy.
A sugar-free label does not describe the sweeteners. The NHS says aspartame is unsuitable for people with PKU, and Pepsi UK lists a phenylalanine statement for standard Pepsi Max.
If PKU is relevant to a guest, check the current ingredients and phenylalanine statement for the exact variant.
A pack of 24 cans and a pack of 16 cans provide different numbers of individual drinks, even when both use 330ml cans. That difference matters when planning servings and chilled storage.
Count the containers and check their volume before deciding how many packs you need.
These range descriptions help distinguish variants; check the current pack for the ingredients and nutrition of the drink you select.

No. Standard Pepsi Max and Diet Coke list caffeine, while Pepsi Max No Caffeine and Diet Coke No Caffeine are separately named variants. Choose one explicitly labelled no caffeine or caffeine-free, and check the exact pack.
Check the exact drink’s ingredients for aspartame and its phenylalanine statement. The NHS says aspartame is unsuitable for people with phenylketonuria (PKU); a zero-sugar label alone does not answer that ingredient question.
Yes. The NHS states that sweeteners undergo a safety assessment before they can be used in food and drink in Great Britain. That general assessment does not remove the need to check a particular drink’s ingredients when PKU is relevant.
