Who is choosing the drinks?

Hosts serving guests of different ages

A cola and a distinct lemon-lime or orange flavour give guests more than one choice. If someone avoids caffeine, set aside a bottle whose exact variant is labelled caffeine-free rather than relying on a zero-sugar label.

Buyers comparing sugar levels

Compare sugars per 100ml across bottles, then check the stated serving size for the glasses you expect to pour. The NHS suggests sugar-free, diet or no-added-sugar drinks as alternatives to sugary fizzy drinks when cutting down on sugar.

Buyers checking caffeine or ingredients

Zero sugar does not establish that a cola is caffeine-free. Read the exact bottle’s ingredient list and sweetener warnings, particularly when a guest needs to avoid a specific ingredient.

What should you check?

Settle on the flavours and bottle quantities first, then compare labels for the needs that matter at your table.

PriorityWhat to checkYour needs
Sugar Compare sugars per 100ml on the nutrition panels, then check each bottle’s stated serving size. Tesco lists Coca-Cola Original Taste 2L at 10.6g sugars per 100ml and Coca-Cola Zero Sugar 2L at 0g; ASDA lists Fanta Orange Zero 2L at 0.4g. I would like guests to be able to choose between an original-sugar drink and a lower-sugar option without guessing from the flavour name.
Caffeine Read the exact variant name and ingredients for caffeine or caffeine flavouring. Tesco’s Coca-Cola Zero Sugar 2L listing includes caffeine flavouring, while its Zero Sugar Zero Caffeine 2L listing identifies a caffeine-free variant. Someone at the table avoids caffeine, so a zero-sugar cola alone does not answer their question.
Flavour Check whether each bottle is cola, lemon-lime or orange-flavoured; confirm the exact variant and 2-litre size rather than relying on the brand name. I want a non-cola choice alongside cola, not several bottles that serve the same flavour preference.
Ingredients Read the sweetener declaration and any warnings on the bottle being served. Keep its label available so guests can check ingredients for themselves. If a guest avoids a particular ingredient, I need the information for the drink actually on the table.
Quantity and stock Check whether the listing is for one 2-litre bottle or a multi-bottle pack, its stated servings and current retailer stock. There should be enough of each planned flavour, without mistaking a case of bottles for a single bottle.

Mistakes to avoid

  • Assuming zero sugar means caffeine-free

    Tesco lists caffeine flavouring in Coca-Cola Zero Sugar 2L, and Pepsi UK lists caffeine in Pepsi MAX. Neither zero-sugar name establishes suitability for a guest avoiding caffeine.

    Choose an explicitly labelled caffeine-free variant and check the ingredients on the exact bottle before serving.

  • Judging sugar by the brand or flavour

    Nutrition figures differ across variants: Tesco lists Coca-Cola Original Taste 2L at 10.6g sugars per 100ml and Coca-Cola Zero Sugar 2L at 0g, while ASDA lists Fanta Orange Zero 2L at 0.4g.

    Use the per 100ml figure for a like-for-like comparison, then check the serving information for the glasses you plan to pour.

  • Overlooking ingredient warnings

    A zero-sugar drink can contain sweeteners, and the Joybuy Coca-Cola Zero Sugar 2L x 6 product information warns that it contains a source of phenylalanine.

    Check the purchased bottle’s ingredient list and warnings, and leave the label available for guests who need to check a specific ingredient.

Brand and variant references

Compare named variants rather than assuming every drink from a brand has the same sugar or caffeine information.

Coca-Cola

Tesco lists 2-litre bottles of Coca-Cola Original Taste, Coca-Cola Zero Sugar and Coca-Cola Zero Sugar Zero Caffeine.

  • Tesco lists Original Taste at 10.6g sugars per 100ml and Zero Sugar at 0g sugars per 100ml.
  • Standard Zero Sugar lists caffeine flavouring; choose the separately named Zero Caffeine variant if caffeine avoidance matters.

Pepsi

Pepsi UK distinguishes regular Pepsi, Pepsi MAX and Pepsi MAX No Caffeine.

  • Pepsi UK lists regular Pepsi at 4.5g sugars per 100ml and Pepsi MAX at 0g sugars per 100ml.
  • Pepsi MAX lists caffeine; Pepsi MAX No Caffeine is a separate variant. Check the pack size and label of the bottle you choose.

Sprite

Tesco lists Sprite Zero Sugar in a 2-litre lemon-lime bottle.

  • The Tesco listing reports 0g sugars per 100ml, offering a non-cola flavour for the table.
  • Confirm current stock before relying on this bottle for a planned event.

Fanta

ASDA lists a 2-litre Fanta Orange Zero bottle as an orange-flavoured alternative to cola.

  • The ASDA listing reports 0.4g sugars per 100ml for Fanta Orange Zero 2L.
  • Coca-Cola GB describes standard Fanta Orange as caffeine-free; check the exact variant’s label rather than applying that description to every Fanta drink.

Joybuy 2-litre cola packs

These Joybuy options are multi-bottle packs of 2-litre colas, rather than single bottles or the non-cola flavours discussed above.

Coca-Cola Zero Sugar 2L x 6 bottles

Coca-Cola Zero Sugar 2L x 6

A cola option for a sharing table where zero sugar is wanted and caffeine is acceptable.

The pack contains six 2-litre bottles. Tesco lists this variant at 0g sugars per 100ml; the Joybuy product information also identifies caffeine and sweeteners and warns that it contains a source of phenylalanine.

Pepsi Regular 8 x 2L bottles

Pepsi Regular 8 x 2L

This is an original-sugar cola route when that flavour is wanted for a larger sharing table.

The pack contains eight 2-litre bottles. Pepsi UK lists regular Pepsi at 4.5g sugars per 100ml; the Joybuy product information also identifies caffeine and sweeteners. Check the purchased bottle’s nutrition panel if sugar level matters to your choice.

View on Joybuy
Diet Coke Caffeine Free 2L x 6 bottles

Diet Coke Caffeine Free 2L x 6

This six-bottle pack provides another 2-litre cola option, but do not rely on its name alone if a guest must avoid caffeine.

The product information states 0g sugars per 100ml and notes sweeteners and a source of phenylalanine. Its caffeine-free description conflicts with safety text referring to caffeine, so check the exact bottle label before choosing it for caffeine avoidance.

Frequently asked questions

Is a zero-sugar fizzy drink automatically caffeine-free?

No. Tesco lists caffeine flavouring in Coca-Cola Zero Sugar 2L, and Pepsi UK lists caffeine in Pepsi MAX. If someone avoids caffeine, choose an explicitly named caffeine-free variant and check the bottle’s ingredients; do not assume the Diet Coke Caffeine Free pack shown here is suitable without checking its label because its product information contains conflicting caffeine statements.

How do I compare sugar across cola and fruit-flavoured bottles?

Compare sugars per 100ml first, then check the stated serving size. Tesco lists 0g sugars per 100ml for Coca-Cola Zero Sugar 2L and Sprite Zero Sugar 2L, and 10.6g for Coca-Cola Original Taste 2L; ASDA lists 0.4g for Fanta Orange Zero 2L. Use the label of the bottle you buy for the final comparison.

What if a guest needs to avoid phenylalanine?

Check the warning on the physical bottle before serving it. The Joybuy Coca-Cola Zero Sugar 2L x 6 and Diet Coke Caffeine Free 2L x 6 product information says these products contain a source of phenylalanine; do not assume other variants have identical ingredients.

How many glasses does a 2-litre bottle provide?

It depends on the glass size. Tesco’s Coca-Cola Original Taste 2L listing describes its bottle as eight 250ml glasses. Check the serving information on your chosen bottle and plan quantities around the sizes you expect to pour.

Can I count on finding a particular 2-litre flavour at one retailer?

Check current stock before making one bottle essential to your festival food plan. Tesco’s Sprite Zero Sugar 2L listing was marked out of stock, so it is sensible to have another suitable non-cola flavour in mind if that is the choice guests need.
