If guests may want to avoid caffeine, choose a cola explicitly labelled caffeine-free rather than assuming that ‘diet’ or ‘zero sugar’ means the same thing. For guests with different preferences, serving a caffeine-free option alongside a standard zero-sugar cola gives them a choice; cans make individual servings easier to count, while the final pack label is the place to check ingredients.
The useful distinction for a christening party is whether guests need a caffeine-free choice, individual cans or a particular pack format.
A standard zero-sugar cola and a clearly labelled caffeine-free cola offer different choices. Diet Pepsi lists caffeine in its ingredients, whereas Pepsi describes Pepsi Max No Caffeine No Sugar as caffeine-free.
Cans give guests a defined serving to pick up. Tesco lists its Diet Pepsi 24-pack as 24 servings of 330 ml, which can help when planning how many cans to buy.
Check the particular variant, not just the own-label name. Tesco describes Xero Cola as containing caffeine, while its separately listed Classic Diet Caffeine Free Cola is caffeine-free.
Settle the caffeine choice first, then compare the sugar statement, ingredient label and number of servings in each pack.
| Priority | What to check | Your needs |
|---|---|---|
| Caffeine | Look for an explicit caffeine-free statement on the exact variant. ‘Diet’, ‘zero sugar’ and ‘no added sugar’ do not establish caffeine status. | I want guests who prefer to avoid caffeine to have a clearly identified cola choice. |
| Sugars | Compare the sugars figure on the label on the same basis, such as per 100 ml or per can. Pepsi UK lists Pepsi Max at 0 g sugars per 100 ml and per 330 ml can; Coca-Cola Great Britain lists Original Taste at 10.6 g per 100 ml. | A cola with 0 g stated sugars matters to me, but I still need to check its caffeine and ingredients separately. |
| Ingredients | Keep the final packaging available for ingredient checks. Tesco lists aspartame and acesulfame K in Diet Pepsi and a statement that it contains a source of phenylalanine; Coca-Cola Zero Sugar information also carries a phenylalanine statement for listed variants. | Guests or carers may want to read the sweetener and phenylalanine information themselves. |
| Servings and format | Check can volume, pack count and total volume rather than counting packs alone. Tesco lists its Diet Pepsi 24-pack as 24 servings of 330 ml, totalling 7.92 litres; its cola listings also include larger bottles. | Individual cans would make self-service and portion counting simpler for my gathering; bottles would need a serving plan. |
Diet Pepsi lists caffeine in its ingredients, while Pepsi Max No Caffeine No Sugar is explicitly identified as caffeine-free. The sugar description alone cannot tell you which drink meets a caffeine preference.
If a caffeine-free option matters for your guests, choose one labelled as such and keep it distinct from the standard cola.
An eight-can pack and a 24-can pack provide different numbers of individual servings. A particular caffeine-free variant may also be unavailable when you shop.
Work from the actual can size and pack count, then check that the chosen variant is available before relying on it for the event.
Guests cannot check a drink’s own ingredient and phenylalanine statements if only unlabelled poured servings are available.
Keep cans or bottles accessible so guests and carers can read the label of the exact drink being served.
Brand families include different sugar and caffeine variants, so choose by the individual product label rather than the brand name alone.
Its range includes Coca-Cola Original Taste, Coca-Cola Zero Sugar and Diet Coke variants, including a caffeine-free listing.
Pepsi offers both standard zero-sugar cola and a variant explicitly named No Caffeine No Sugar.
Tesco’s own-label listings include standard diet or sugar-free cola and a separately identified caffeine-free variant.
These 24 × 330 ml can packs cover caffeine-free and standard diet or zero-sugar cola choices for serving at a gathering. Check the exact pack label and availability when ordering.

No. Pepsi describes Pepsi Max No Caffeine No Sugar as caffeine-free, but Tesco lists caffeine among Diet Pepsi’s ingredients and describes Tesco Xero Cola as containing caffeine. Check the exact variant rather than relying on ‘diet’ or ‘zero sugar’ in its name.
The label lets guests or carers check the ingredients of the drink actually being served. Tesco’s Diet Pepsi listing names sweeteners and includes a source-of-phenylalanine statement; Coca-Cola Zero Sugar information also includes that statement for listed variants.
Choose cans if individual servings and self-service matter: Pepsi identifies a 330 ml can as one serving, and Tesco lists 24 servings in its 24 × 330 ml Diet Pepsi pack. If using bottles, plan how they will be served and calculate the volume needed from the number of expected cola drinkers.
Use the final pack label for ingredients, since formulations can change, and confirm that your chosen variant is available before the event. This is particularly important if the caffeine-free cola is needed as a distinct choice.
