Hosts planning a self-serve buffet
Individual 330ml cans give guests sealed portions to pick up. Sharing bottles call for cups, chilled storage and a plan for handling bottles after opening.
Who is this choice for?
The serving format, the wording on the pack and any need for a caffeine-free choice can each change what belongs on the drinks table.
Hosts serving guests who avoid sugar
Check the exact product label and sugars per 100ml. A cola described as zero sugar or diet should not automatically be presented as carrying a 'no added sugar' claim.
Hosts providing a caffeine-free choice
Look for a named caffeine-free variant and identify it separately at the buffet. Standard Coca-Cola Zero Sugar and Pepsi Max list caffeine, while both brands offer distinct caffeine-free versions.
What should you check before buying?
Start with the claim your buffet needs to make, then choose a serving format and check whether any guests need a distinct caffeine-free option.
| Priority | What to check | Your needs |
|---|---|---|
| Label wording | Read the exact pack claim and sugars per 100ml. Tesco calls its Diet Cola 'no added sugar'; Coca-Cola Zero Sugar and Pepsi Max list 0g sugars per 100ml, according to their respective product information. | If I need to describe the drink as 'no added sugar', I want the pack itself to carry that wording. |
| Serving format | Check the number and size of cans or bottles against planned servings and chilled storage. For bottles, arrange cups and a way to handle them after opening. | Sealed cans would simplify my self-serve table; bottles would work if someone can look after pouring and opened drinks. |
| Caffeine | Check the full variant name and ingredient list. Standard Coca-Cola Zero Sugar and Pepsi Max contain caffeine; Coca-Cola Zero Sugar Caffeine Free and Pepsi Max No Caffeine are separately named variants. | Some guests may want cola without caffeine, so I would keep that variant clearly separate from standard cans or bottles. |
| Ingredients | Read the sweeteners and any source-of-phenylalanine statement on each variant. Keep the packaging available so guests can identify the drink they are taking. | I want guests to be able to check ingredients without relying on a handwritten brand name alone. |
What can go wrong at the buffet?
-
Treating 'diet', 'zero sugar' and 'no added sugar' as the same pack claim
A sign promising 'no added sugar' may not match the wording on the drink being served. Tesco describes its Diet Cola with that claim, while the cited Coca-Cola Zero Sugar and Pepsi Max information describes zero-sugar products.
Decide which wording matters for the event, then check the claim and nutrition panel on the exact pack before making a buffet sign.
-
Assuming zero-sugar cola is caffeine-free
Standard Coca-Cola Zero Sugar and Pepsi Max list caffeine; their named caffeine-free variants are different products.
If you are providing a caffeine-free choice, buy a variant explicitly labelled caffeine-free and mark its place on the table separately.
-
Putting out drinks without their ingredient information
Sweeteners and source-of-phenylalanine statements vary by product. A brand name alone does not identify every ingredient in a particular variant.
Keep each variant identifiable and retain its packaging so guests can read the exact label.
-
Choosing bottles without a serving plan
Sharing bottles need cups and handling after opening, while individual cans need space to chill the planned quantity. Tesco's directions say to consume its 2-litre Diet Cola within three days of opening.
Count planned servings and check the available chilling space before choosing between cans and bottles.
Which brands and ranges are relevant?
Compare the named variant, pack format and label rather than assuming every cola from one brand has the same recipe.
Coca-Cola
Coca-Cola Zero Sugar is listed in individual-can packs, and Coca-Cola also names a separate Zero Sugar Caffeine Free variant.
- Coca-Cola Great Britain lists 0g sugars per 100ml for Coca-Cola Zero Sugar.
- Standard Coca-Cola Zero Sugar lists caffeine and sweeteners, including aspartame; check the variant if caffeine avoidance or ingredients matter.
Pepsi
Pepsi Max is a no-sugar cola offered in can packs; Pepsi Max No Caffeine is a distinct variant.
- Pepsi UK lists 0g sugars per 100ml for Pepsi Max and describes Pepsi Max No Caffeine as having zero sugar and zero caffeine.
- Standard Pepsi Max contains caffeine. Check the sweeteners and phenylalanine statement on the exact variant.
Tesco
Tesco Diet Cola is a 2-litre sharing-bottle option explicitly described by Tesco as 'no added sugar'.
- Tesco lists less than 0.1g sugars per 100ml and says to consume the bottle within three days of opening.
- The listed recipe contains caffeine, acesulfame K and sucralose; check the delivered label for the current ingredients.
Sainsbury's
Sainsbury's lists Cola Zero and Diet Cola in separate 2-litre formats.
- Sainsbury's lists less than 0.5g sugars per 100ml for its Diet Cola.
- Its Diet Cola ingredient listing includes caffeine, acesulfame K and sucralose. Do not assume the Cola Zero variant has the same recipe or pack claim.

Common questions
Does 'zero sugar' automatically mean the pack says 'no added sugar'?
No. Check the exact pack if 'no added sugar' is the wording you need for the buffet. Tesco uses that wording for its Diet Cola, while Coca-Cola Zero Sugar and Pepsi Max are described as zero-sugar products in their manufacturers' information.
Which cola variants offer a caffeine-free, zero-sugar choice?
Coca-Cola Great Britain lists Coca-Cola Zero Sugar Caffeine Free, and Pepsi UK lists Pepsi Max No Caffeine. Both are distinct from the standard variants, whose ingredient information includes caffeine; check the full name on the pack before putting it out.
Why keep the ingredient label beside zero-sugar cola?
Guests may need to distinguish sweeteners and source-of-phenylalanine statements between exact variants. Keep the original cans or bottles identifiable, or retain the packaging where guests can check it.
Are cans or 2-litre bottles easier for a wedding buffet?
Cans provide sealed, individual portions for self-service; 2-litre bottles need cups, chilling and handling after opening. Choose against your venue setup and planned servings. For its own 2-litre Diet Cola, Tesco says to consume the drink within three days of opening.
