Hosts offering a lower-sugar choice
Put a clearly labelled zero-sugar option alongside other drinks rather than making regular cola the only fizzy choice. Check the nutrition label on the pack you plan to serve.
Who needs a different drink option?
A mixed brunch table can call for more than one kind of fizz: lower sugar, no caffeine and ingredient checks are distinct considerations.
Guests avoiding caffeine as well as sugar
Look for a product explicitly labelled caffeine-free. Coca-Cola GB identifies a caffeine-free Coca-Cola Zero Sugar variant, while Pepsi UK describes Pepsi Max Caffeine Free as containing no sugar or caffeine; an ordinary zero-sugar cola is not interchangeable with either.
Hosts checking a guest’s PKU requirements
Phenylketonuria (PKU) makes the sweetener declaration important. The NHS says aspartame is unsuitable for people with PKU, so check the exact ingredients and phenylalanine warning against the guest’s dietary requirements before serving.
What should you check before choosing?
Start with the dietary requirement that matters to each guest, then compare the label on the specific drink and serving size.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar | Compare sugars per 100ml on the nutrition labels, then check the can or bottle size. Pepsi UK lists 15g sugars in a 330ml can of Pepsi Classic, while its Pepsi Max range includes zero-sugar options. | I want guests to have a fizzy choice with less sugar than regular cola, without making everyone choose the same drink. |
| Caffeine | Look for an explicit caffeine-free claim and read the ingredients. Coca-Cola GB lists caffeine flavouring for Coca-Cola Zero Sugar; Pepsi UK lists caffeine in Pepsi Max flavourings, while both brands identify separate caffeine-free variants. | Someone avoiding caffeine should be able to identify their drink without guessing from a diet or zero-sugar label. |
| Sweeteners | Check the exact pack for aspartame or E951 and a phenylalanine warning. The NHS says aspartame is unsuitable for people with PKU; UK food-labelling guidance requires a phenylalanine warning where a product contains aspartame. | If a guest has PKU, I need to check the ingredients against their dietary requirements rather than assume a sugar-free drink is suitable. |
| Flavour choice | Check the sugar and caffeine information on each non-cola drink rather than inferring it from the flavour. Coca-Cola GB lists 0g sugars for Sprite no sugar; Tesco Groceries also lists Fanta Zero fruit-flavoured variants. | Not everyone wants cola, so a labelled non-cola option would give the group another flavour choice. |
| Children’s drinks | Keep water available as well as fizz. Medway Community Healthcare’s dental guidance warns that acidic fizzy drinks, including sugar-free ones, can wear tooth surfaces. | When children join brunch, I do not want a zero-sugar label to be mistaken for a tooth-friendly everyday-drink claim. |
Which assumptions can cause problems?
-
Assuming every zero-sugar cola is caffeine-free
Coca-Cola GB and Pepsi UK list caffeine in their standard zero-sugar colas and offer separately named caffeine-free versions.
Choose a specifically caffeine-free product when that distinction matters, and check its current pack.
-
Assuming sugar-free means suitable for PKU
The NHS says aspartame is unsuitable for people with PKU because it contains phenylalanine. A sugar-free claim does not settle that ingredient question.
Check the exact pack for aspartame or E951 and the phenylalanine warning, and follow the guest’s dietary requirements.
-
Treating sugar-free fizz as tooth-friendly for children
Medway Community Healthcare’s dental guidance warns that acidic fizzy drinks can wear tooth surfaces, including when the drinks are sugar-free.
Keep water available at a family brunch rather than presenting zero-sugar fizz as a substitute for it.
Which brand ranges illustrate the options?
These brand ranges show why the variant name and its current label matter more than the brand name alone.
Coca-Cola
Coca-Cola GB identifies both Coca-Cola Zero Sugar and a separate caffeine-free zero-sugar variant.
- Its Coca-Cola Zero Sugar product information lists 0g sugars and includes caffeine flavouring in the ingredients.
- Choose the specifically caffeine-free variant when caffeine avoidance matters; check the selected pack’s sweeteners for PKU-related requirements.
Pepsi
Pepsi UK distinguishes regular Pepsi Classic, zero-sugar Pepsi Max and Pepsi Max Caffeine Free.
- Pepsi UK lists zero sugar and zero caffeine for Pepsi Max Caffeine Free.
- Pepsi Classic lists 15g sugars per 330ml can, while standard Pepsi Max lists caffeine in its flavourings; neither is the same choice as the caffeine-free variant.
Sprite
Sprite gives guests a lemon-and-lime alternative to cola.
- Coca-Cola GB lists 0g sugars for Sprite no sugar.
- Its listed sweeteners include aspartame. Check the current pack for caffeine information and PKU-related requirements rather than drawing conclusions from its flavour.
Fanta
Tesco Groceries lists Fanta Zero Orange and Fanta Zero Fruit Twist as fruit-flavoured alternatives.
- The two listed variants give a brunch group different fruit-flavour choices.
- Check the individual pack for its nutrition, caffeine and sweetener details before assigning it a dietary role.
Tesco
Tesco Groceries lists own-label drinks alongside branded diet and sugar-free fizzy drinks.
- Its listings include Tesco Xero Cola as another named cola option.
- An own-label range name does not establish the ingredients or caffeine status of every variant; compare individual labels.

Brunch drink questions
Do the named zero-sugar colas contain less sugar than regular Pepsi?
Yes, on the labels cited here. Coca-Cola GB lists 0g sugars for Coca-Cola Zero Sugar, and Pepsi UK lists zero sugar for Pepsi Max and Pepsi Max Caffeine Free; Pepsi UK lists 15g sugars in a 330ml can of Pepsi Classic. Check the serving size and current label when choosing other variants.
Is a diet or zero-sugar cola automatically caffeine-free?
No. Coca-Cola GB lists caffeine flavouring for Coca-Cola Zero Sugar, and Pepsi UK lists caffeine in Pepsi Max flavourings. Choose a specifically labelled caffeine-free variant and confirm the selected pack.
What should I check before offering a diet drink to someone with PKU?
Check the exact ingredients for aspartame or E951 and the phenylalanine warning against the guest’s dietary requirements. The NHS says aspartame is unsuitable for people with PKU; UK food-labelling guidance requires a phenylalanine warning when a product contains it.
Are sugar-free fizzy drinks tooth-neutral for children?
No. Medway Community Healthcare’s dental guidance warns that acidic fizzy drinks, including sugar-free versions, can wear tooth surfaces. Keep water available for children at brunch rather than treating zero-sugar fizz as a tooth-friendly substitute.
