Hosts serving adults and families
A cola and a contrasting fruit-flavoured option give guests a choice of flavours. If anyone avoids caffeine, choose a drink whose exact label says it is caffeine free rather than relying on its flavour.
Who is choosing the drinks?
Hosts offering a zero-sugar cola
Compare the nutrition panel of the exact cola variant. Coca-Cola Great Britain lists 0g sugars per 100ml for Coca-Cola Zero Sugar, and Pepsi UK lists the same for Pepsi Max; both list caffeine and aspartame.
Hosts checking caffeine or PKU requirements
Look for an explicit caffeine-free label and check ingredients separately. The NHS says aspartame is not suitable for people with phenylketonuria (PKU), so a zero-sugar label alone does not establish suitability.
What should you check before buying?
Choose the flavour mix first, then compare the exact labels and pack volumes for the drinks you plan to serve.
| Priority | What to check | Your needs |
|---|---|---|
| Flavour choice | Check whether the drinks are cola, citrus or another fruit flavour. Compare regular and zero-sugar variants by their exact names. | I want a familiar cola without making it the only flavour guests can choose. |
| Sugars | Compare sugars per 100ml on the same basis. Coca-Cola Great Britain lists 10.6g for Original Taste and 0g for Zero Sugar; Pepsi UK lists 0g for Pepsi Max. | A clearly labelled zero-sugar cola would let guests choosing that option distinguish it from regular cola. |
| Caffeine and ingredients | Check for an explicit caffeine-free statement and read the sweetener and phenylalanine information. Coca-Cola Great Britain describes Fanta Orange as caffeine free, but lists 4.5g sugars per 100ml. | If a guest avoids caffeine or has PKU, I need to check the exact drink rather than assume a fruity or zero-sugar variant suits them. The NHS says aspartame is not suitable for people with PKU. |
| Pack format | Compare can count, volume per can and total volume. Check that you have room to store and chill the packs you choose. | Individual cans would make it straightforward to set out more than one flavour and let guests pick a drink. |
Common buying mistakes
-
Assuming zero sugar means caffeine free
Coca-Cola Great Britain and Pepsi UK list caffeine in Coca-Cola Zero Sugar and Pepsi Max. Both also list aspartame; the NHS says aspartame is not suitable for people with PKU.
Read the exact variant’s ingredients and choose a separately labelled caffeine-free drink where needed. Check phenylalanine warnings before offering a drink to a guest with PKU.
-
Comparing multipacks by can count alone
A can count does not tell you the total volume unless you also check the size of each can. It may leave you with a different quantity of drink than you planned to chill or serve.
Compare the volume per can and total volume, then decide how much of each flavour to set out for the group.
Brand and retailer references
These examples show why the exact drink and variant matter; a brand name alone does not establish its sugar, caffeine or ingredient information.
Coca-Cola
Original Taste and Zero Sugar offer two cola variants to compare for a party.
- Coca-Cola Great Britain lists 10.6g sugars per 100ml for Original Taste and 0g for Zero Sugar.
- Its Zero Sugar information lists caffeine and aspartame and carries a phenylalanine warning; do not treat it as a caffeine-free option.
Pepsi
Pepsi Max is a zero-sugar cola option for guests who want cola.
- Pepsi UK lists 0g sugars per 100ml for Pepsi Max.
- The Pepsi Max ingredient information includes caffeine and aspartame and states that it contains a source of phenylalanine.
Sprite
Sprite provides a lemon-and-lime alternative to cola, with regular and Zero variants.
- Coca-Cola Great Britain lists 4.4g sugars per 100ml for Sprite and 0g for Sprite Zero.
- Check the exact variant’s ingredients and phenylalanine warning when serving a guest with PKU.
Fanta
Fanta Orange is a fruit-flavoured choice for guests who do not want cola.
- Coca-Cola Great Britain describes Fanta Orange as caffeine free.
- The manufacturer lists 4.5g sugars per 100ml, so caffeine free does not mean zero sugar.
Dr Pepper
Standard and Zero variants offer another flavour choice beyond cola and citrus.
- Coca-Cola Great Britain lists 4.3g sugars per 100ml for standard Dr Pepper and 0g for Dr Pepper Zero.
- The cited standard Dr Pepper information lists caffeine. Check the exact variant before offering it to someone avoiding caffeine.
Tesco
Tesco’s grocery listings provide examples of cola multipacks and own-label flavoured sparkling water to compare by format.
- Tesco Groceries lists 24-can zero-sugar cola packs alongside flavoured sparkling-water products.
- Check each listed pack’s volume, ingredients and current availability rather than treating a category listing as the product label.

Christmas-party drinks FAQs
Is a zero-sugar fizzy drink suitable for every guest?
No. Coca-Cola Great Britain and Pepsi UK list aspartame and a phenylalanine warning for Coca-Cola Zero Sugar and Pepsi Max. The NHS says aspartame is not suitable for people with phenylketonuria (PKU), so check the exact drink’s ingredients before serving it to a guest with PKU.
How can I offer a caffeine-free fizzy drink?
Choose a variant explicitly labelled caffeine free, rather than assuming every fruity drink is. Coca-Cola Great Britain describes Fanta Orange as caffeine free and lists 4.5g sugars per 100ml, so it is not a zero-sugar substitute.
Should I choose cans or bottles for a Christmas party?
Cans suit individual portions and make it easy to set out several flavours; larger bottles suit guests pouring their own drinks if you have room to chill them. Compare total volume as well as container size before deciding how much of each drink to buy.
