What should you check?
Set the sugar-declaration requirement and flavour choice first, then check ingredients and how the drinks will be served.
Cloudy no-added-sugar lemonade
Choose it when: A cloudy lemonade with lemon ingredients suits the menu.
Bear in mind: The Tesco and Sainsbury's examples declare sugars despite their no-added-sugar descriptions, and their ingredients require a sulphites check.
Clear diet lemonade
Choose it when: A 0g-sugars declaration matters more than a cloudy style; ASDA Diet Lemonade lists 0g per 100ml and per 250ml.
Bear in mind: The ASDA product is sweetened with acesulfame K and sucralose, so check that its ingredients suit the guests.
Zero-sugar lemon-lime drink
Choose it when: A lemon-lime soft drink, rather than conventional lemonade, fits the buffet menu.
Bear in mind: The Sprite Zero Sugar listing includes aspartame and a phenylalanine warning; check the exact product before serving.
| Priority | What to check | Your needs |
| Sugars declaration | Read sugars per 100ml and per serving on the exact bottle. Do not treat “no added sugar” as a 0g declaration. | I want the drink to match what the buffet menu promises, whether that is no added sugar or a stated 0g sugars. |
| Ingredients | Check sweeteners, aspartame and any phenylalanine warning. Check the current ingredients and allergen information for sulphites. | Guests need enough information to choose a drink that suits their ingredient requirements. |
| Flavour | Distinguish cloudy lemonade, clear diet lemonade and lemon-lime soft drinks by their product descriptions. | If the menu says lemonade, I do not want to assume a lemon-lime drink will taste like the option guests expect. |
| Serving format | Count portions using the actual bottle or can size. Check chilling and after-opening instructions before setting drinks out. | Individual cans may suit self-service; shared bottles need a plan for pouring, chilling and leftovers. |

Questions about buffet drinks
Does no added sugar mean 0g sugars?
No. Tesco Groceries and Sainsbury's each list 0.6g sugars per 250ml for their cloudy no-added-sugar lemonades. If your menu calls for a 0g declaration, check the sugars line on the exact bottle; ASDA Groceries lists 0g per 250ml for ASDA Diet Lemonade.
What ingredient information should guests be able to check?
Keep the current bottle labels or supplier ingredient information available, particularly if drinks are poured into shared dispensers. That lets guests check the ingredients and allergen information for the exact product rather than an older online listing.
Why do some zero-sugar drinks carry a phenylalanine warning?
The warning relates to aspartame. GOV.UK guidance specifies a source-of-phenylalanine warning when aspartame is named in the ingredients, and the NHS says aspartame is unsuitable for people with PKU. The listed R.White's Diet Lemonade and Sprite Zero Sugar examples contain aspartame.
Are cloudy no-added-sugar lemonades free from sulphites?
Not necessarily. Sainsbury's lists sulphites in the lemon ingredients of its cloudy lemonade, and Tesco Groceries lists sodium metabisulphite in its version. Check the current label of the exact drink you intend to serve.
Should all the bottles be opened before guests arrive?
Open bottles in stages according to likely demand. The Tesco, Sainsbury's and ASDA 2-litre lemonade listings give after-opening storage instructions, including use within three days; check the bottle you buy and arrange chilled storage for those left over.
