Who is choosing the drinks?

Hosts serving mixed preferences

If you do not know what everyone likes, a regular cola, a zero-sugar choice and an explicitly caffeine-free choice cover different requests without treating them as interchangeable.

Hosts comparing sugar and sweeteners

Check sugars per 100ml when comparing regular and zero-sugar recipes. If ingredients matter to a guest, read the exact zero-sugar pack for sweeteners and caffeine too.

Hosts planning outdoor serving

Individual 330ml cans and larger sharing bottles call for different fridge and serving arrangements. Think about how guests will take their drinks before choosing a pack format.

What should you check before buying?

Decide which recipes to offer, then check the exact labels and choose pack sizes that suit your serving space.

Priority What to check Your needs
Sugar and energy Compare the same measure on each variant’s nutrition label, such as sugars per 100ml. Pepsi UK lists 0g sugars per 100ml for Pepsi MAX and 4.5g for Pepsi Classic; a Joybuy UK listing gives 10.6g for Coca-Cola Original Taste. I want a zero-sugar option alongside regular cola if guests prefer different recipes. I can use the per-100ml labels to distinguish them rather than assuming all regular colas have the same sugar content.
Caffeine Look for an explicitly caffeine-free product name and check the ingredient list. Coca-Cola Great Britain and Pepsi UK list separate caffeine-free zero-sugar variants; their standard zero-sugar colas list caffeine or caffeine flavouring. If someone avoids caffeine, I need a separately labelled caffeine-free choice—not just a can marked zero sugar.
Sweeteners and PKU Check the exact pack for aspartame, also called E951, and a phenylalanine statement. The NHS says aspartame is unsuitable for people with phenylketonuria (PKU). For a guest with PKU, I cannot assume that a sugar-free cola is suitable. I need to check its ingredients before serving it.
Flavour Read the full variant name rather than relying on the brand or the word ‘cola’. Check sugar, caffeine and sweeteners separately for a flavoured recipe. A flavoured can could add variety when a classic cola is already on the table, but I still want its label to match guests’ requirements.
Pack format Check can or bottle size, the number in the pack and the space available for chilling. Joybuy UK listings include 330ml can multipacks and a six-pack of 2-litre bottles. For individual servings, cans make portions straightforward. If guests will share bottles at the table, I need room to chill and serve them.

What is easy to overlook?

  • Assuming zero sugar means no caffeine

    Coca-Cola Great Britain and Pepsi UK list caffeine in their standard zero-sugar colas, while their caffeine-free versions are separate variants.

    If caffeine avoidance matters, choose a product explicitly labelled caffeine-free and check its pack.

  • Assuming sugar-free fizzy drinks are tooth-neutral

    The NHS notes that acids in carbonated drinks are associated with dental erosion, whether the drink contains sugar or sweeteners.

    Make water available alongside cola rather than treating a zero-sugar fizzy drink as equivalent to water.

  • Overlooking aspartame when serving someone with PKU

    The NHS says aspartame is unsuitable for people with phenylketonuria because it contains phenylalanine. Coca-Cola Zero Sugar and Pepsi MAX list aspartame in their UK product information.

    Check the exact pack for aspartame or E951 and a phenylalanine statement before serving it to a guest with PKU.

  • Relying on a range name for the ingredient list

    Sweetener details on a Coca-Cola Zero Sugar product-family page and a Joybuy UK listing are not identical, although both list zero sugars.

    Use the ingredients on the physical pack when the precise formulation matters, and check the size and best-before date when the drinks arrive.

Which cola ranges are relevant?

A brand name alone does not tell you whether a particular cola contains sugar, caffeine or sweeteners; compare the named variants.

Coca-Cola

The UK range includes Original Taste, Zero Sugar and Zero Sugar Caffeine Free.

  • Coca-Cola Great Britain lists 0g sugars per 100ml for both named zero-sugar variants; Zero Sugar Caffeine Free is a separate caffeine-free choice.
  • A Joybuy UK listing gives 10.6g sugars per 100ml for Original Taste. Check the exact zero-sugar pack for its sweeteners and phenylalanine statement.

Pepsi

The UK range includes Pepsi Classic, Pepsi MAX and Pepsi MAX No Caffeine, with flavoured MAX variants for a different taste.

  • Pepsi UK lists 0g sugars per 100ml for Pepsi MAX and Pepsi MAX No Caffeine, compared with 4.5g for Pepsi Classic.
  • Pepsi MAX lists caffeine. Check sweeteners and phenylalanine wording on the specific MAX variant, particularly when buying for someone with PKU.

RC Cola

RC Cola International describes a range of carbonated drinks, including cola.

  • It offers another brand to consider if you want a different cola flavour on the drinks table.
  • For a specific pack, check its UK label for sugars, ingredients, caffeine and serving size rather than assuming it matches another brand’s recipe.

Frequently asked questions

Should I offer both regular and zero-sugar cola at a BBQ?

Offer both if guests prefer different recipes; a zero-sugar option does not replace regular cola for someone who specifically wants it. Compare labels on the same basis: Pepsi UK lists 0g sugars per 100ml for Pepsi MAX and 4.5g for Pepsi Classic, while a Joybuy UK listing gives 10.6g for Coca-Cola Original Taste.

Does zero-sugar cola contain caffeine?

It can. Coca-Cola Great Britain and Pepsi UK list caffeine or caffeine flavouring in standard Coca-Cola Zero Sugar and Pepsi MAX. If someone avoids caffeine, choose an explicitly named caffeine-free variant and check its pack.

What should I check when buying cola for someone with PKU?

Check the exact pack for aspartame or E951 and a phenylalanine statement. The NHS says aspartame is unsuitable for people with phenylketonuria (PKU); the UK Coca-Cola Zero Sugar and Pepsi MAX product information lists aspartame.

Are sugar-free fizzy drinks tooth-neutral?

No. The NHS notes that acids in carbonated drinks are associated with dental erosion whether the drinks contain sugar or sweeteners. A zero-sugar label tells you about sugar, not acidity.

What should I offer children alongside cola at a BBQ?

Make water readily available. NHS guidance says children should avoid sugary fizzy drinks, so do not treat regular cola as their everyday drink.
