Hosts comparing sugar content
If you are serving children, families or mixed-age guests, compare ‘of which sugars’ per 100ml on each flavour and variant. A familiar brand name does not tell you whether the particular drink lists 0g sugars.
Who is choosing?
Hosts catering for caffeine-sensitive guests
If caffeine matters to your guests, check the exact pack rather than making caffeinated cola the only lower-sugar fizzy option. Pepsi Max Caffeine-Free is a cola option that Pepsi UK describes as having zero caffeine and zero sugar.
Hosts checking ingredients for guests
If a guest needs to avoid aspartame because of phenylketonuria (PKU), read the ingredients and phenylalanine warning on every pack. A zero-sugar label does not mean the drink contains no sweeteners.
What to check before buying
Choose the flavours your guests are likely to drink, then compare the sugar figure, ingredients and caffeine status of each exact variant.
| Priority | What to check | Your needs |
|---|---|---|
| Listed sugars | Compare ‘of which sugars’ per 100ml on the exact flavour and pack. Coca-Cola GB lists 0g for Coca-Cola Zero Sugar and Sprite Zero, but 0.4g for Fanta Fruit Twist Zero. | If I want a drink with no listed sugar, I’ll use the per-100ml figure rather than assume every ‘Zero’ variant has the same value. |
| Sweeteners | Read the ingredients for sweeteners, particularly aspartame, and check for a phenylalanine warning when catering for someone with PKU. | I need to know what is in each drink before offering it to a guest who must avoid aspartame. |
| Caffeine | Check the caffeine information on each variant. Pepsi UK describes Pepsi Max Caffeine-Free as containing zero caffeine; its regular Pepsi Max lists caffeine. | A caffeine-free fizzy option matters if some guests do not want caffeine, even if others prefer cola. |
| Other drinks | Make water available alongside the fizzy selection. The NHS notes that carbonated drinks are associated with dental erosion because of their acid content. | I want guests to have a choice besides fizzy drinks throughout the party. |
Common buying mistakes
-
Assuming ‘zero sugar’ means no ingredients to check
Zero-sugar drinks can contain sweeteners. Aspartame and the accompanying phenylalanine warning matter when choosing a drink for someone with PKU.
Read the ingredients and warnings on the exact flavour and pack, not just its front label.
-
Treating every ‘Zero’ variant as 0g sugars
Coca-Cola GB lists 0g sugars per 100ml for Sprite Zero, while Fanta Fruit Twist Zero lists 0.4g per 100ml. The variant name alone does not give you the figure.
Compare ‘of which sugars’ per 100ml if 0g is your selection criterion.
-
Offering only caffeinated cola
Coca-Cola Zero Sugar, Pepsi Max and Dr Pepper Zero list caffeine. Pepsi UK describes Pepsi Max Caffeine-Free as a zero-caffeine, zero-sugar alternative.
Check caffeine status when planning choices for mixed-age or caffeine-sensitive guests, and keep water available.
-
Assuming no sugar removes dental considerations
The NHS associates carbonated drinks with dental erosion because of their acid content; a zero-sugar label does not address that consideration.
Offer water as another readily available drink during the party.
Brand and range references
These UK product ranges illustrate why the exact variant matters; a brand name alone does not establish its sugar or ingredient content.
Coca-Cola
Coca-Cola Zero Sugar is a cola option for hosts comparing drinks that list 0g sugars per 100ml.
- Coca-Cola GB lists 0g sugars per 100ml for Coca-Cola Zero Sugar.
- Its ingredients include caffeine and sweeteners; check the pack for aspartame and its phenylalanine warning when relevant.
Pepsi
Pepsi Max and Pepsi Max Caffeine-Free offer two cola variants with different caffeine status.
- Pepsi UK lists 0g sugars per 100ml for Pepsi Max and describes Pepsi Max Caffeine-Free as having zero sugar and zero caffeine.
- Check both packs for sweeteners and the phenylalanine warning if a guest must avoid aspartame.
Sprite
Sprite Zero provides a lemon-and-lime flavour for guests who would rather not have cola.
- Coca-Cola GB lists 0g sugars per 100ml for Sprite Zero.
- Check the exact variant and its ingredients rather than assuming every Sprite drink has the same sugar figure.
Fanta
Fanta Fruit Twist Zero is a fruit-flavour option, but its sugar figure needs checking against a 0g-per-100ml requirement.
- Coca-Cola GB lists the variant’s sugar content per 100ml, making it possible to compare the exact drink.
- Fanta Fruit Twist Zero lists 0.4g sugars per 100ml, not 0g.
Dr Pepper
Dr Pepper Zero offers another flavour for guests who specifically want Dr Pepper.
- Coca-Cola GB lists 0g sugars per 100ml for Dr Pepper Zero.
- It lists caffeine; check its sweeteners and phenylalanine warning when choosing for a guest with PKU.

Questions about sugar and ingredients
Does ‘no added sugar’ mean a fizzy drink contains no sugar or sweeteners?
No. A drink can contain sweeteners, and its ‘of which sugars’ figure may not be 0g. Check both the per-100ml nutrition information and ingredients on the exact flavour and pack; Coca-Cola GB, for example, lists 0.4g sugars per 100ml for Fanta Fruit Twist Zero.
Can someone with PKU have any zero-sugar fizzy drink?
Do not choose a drink containing aspartame for someone with phenylketonuria (PKU). Check each pack’s ingredients and source-of-phenylalanine warning, including when you switch between flavours or variants.
Does zero sugar remove the dental considerations of fizzy drinks?
No. The NHS notes that carbonated drinks are associated with dental erosion because of their acid content. Keep water available as an alternative during the party.
