If reducing sugar in the brunch drink matters, diet lemonade is worth considering: Sainsbury's lists less than 0.5g sugars per 250ml for its Diet Lemonade, compared with 8.8g for its standard Lemonade. For a shared table, check the number of servings, opened-bottle storage instructions and sweeteners before choosing. Sugar-free fizzy drinks can still be acidic; NHS dental guidance for children advises keeping acidic drinks to mealtimes.
Who is choosing the drink?
The useful starting point depends on how many people you are serving and whether anyone needs to check particular ingredients.
Hosts serving a small brunch group
Match the bottle to the number of glasses you expect to pour. Sainsbury's and Asda each describe eight 250ml servings in their 2L diet lemonades and instruct shoppers to refrigerate the bottles after opening and use them within three days.
Shoppers comparing sugar per glass
Read the sugars figure for the amount you plan to serve, rather than relying on the word “diet”. Sainsbury's lists less than 0.5g sugars per 250ml for its Diet Lemonade; Asda lists 0g for the same serving size. Both use sweeteners.
Guests checking sweetener ingredients
Compare the exact product labels. M&S lists sucralose in its Diet Lemonade, while Tesco's R. White's Diet Lemonade listings include aspartame and a phenylalanine statement.
What should you check?
Start with sugars per serving, then choose a format you can use and check the ingredients on the drink you intend to serve.

Your needs |
| Sugars per glass |
Compare sugars for the same serving size, not just the front-of-pack wording. Sainsbury's lists less than 0.5g per 250ml for its Diet Lemonade and 8.8g per 250ml for its standard Lemonade; Asda lists 0g per 250ml for its Diet Lemonade. |
I'd like a fizzy brunch drink with less declared sugar than the standard lemonade I'm comparing it with. |
| Quantity and storage |
Count the likely pours against the stated serving size. Sainsbury's and Asda each describe eight 250ml servings in a 2L bottle and specify refrigeration and use within three days after opening. |
For several guests, one large bottle may be convenient; for fewer pours, I'd rather consider smaller portions than leave much of an opened bottle. |
| Sweetener ingredients |
Read the named sweeteners and any phenylalanine statement on the pack. M&S lists sucralose for its Diet Lemonade; Tesco's R. White's Diet Lemonade listings include aspartame, acesulfame K and saccharin. |
If an ingredient matters to someone at the table, I need the formulation of the exact drink being served. |
| Flavour |
Check whether the drink is lemonade or lemon-and-lime flavoured. The Coca-Cola Company GB describes Sprite Zero as a lemon-and-lime drink with 0g sugars per 100ml. |
I'd choose a lemon-and-lime alternative only if that flavour appeals to the guests expecting lemonade. |
| When it is served |
Do not treat a zero-sugar figure as a measure of acidity. NHS dental guidance for children identifies fizzy drinks among acidic drinks that can cause tooth erosion and advises keeping them to mealtimes. |
When children are joining brunch, I can serve the fizzy drink with the meal and offer water between meals. |
Common buying mistakes
-
Assuming “diet” means unsweetened
Diet lemonades can contain different sweeteners. M&S lists sucralose in its Diet Lemonade, while Tesco's R. White's Diet Lemonade listings include aspartame and a phenylalanine statement.
Check the ingredient list and any statements on the exact bottle or can before serving someone with a relevant restriction or ingredient preference.
-
Buying 2L without a plan for the remainder
Sainsbury's and Asda each describe eight 250ml servings in their 2L diet lemonades. Both specify refrigerated storage and use within three days after opening.
Estimate how many glasses brunch will use, then compare a sharing bottle with smaller portions if leftovers are likely.
-
Equating sugar-free with tooth-neutral
NHS dental guidance for children says acidic fizzy drinks can cause tooth erosion. That consideration remains even when a drink's sugars figure is zero.
Serve fizzy drinks with the brunch meal rather than repeatedly between meals, and offer water as another drink.
-
Relying on an old online ingredient list
The ingredients and instructions that matter are those for the drink you will serve, particularly when checking sweeteners or opened-bottle storage.
Read the ingredients, nutrition panel, date marking and storage instructions on the pack received.
Brand and product-line references
These named drinks illustrate differences in format and formulation; details for one product should not be assumed to apply to every drink from its brand.
Sainsbury's
Its 2L Diet Lemonade is a sharing-bottle reference for comparing sugars per glass and opened-bottle instructions.
- Sainsbury's lists eight 250ml servings, each with 3kcal and less than 0.5g sugars.
- The retailer instructs shoppers to refrigerate the bottle after opening and use it within three days.
Asda
Its 2L Diet Lemonade provides another stated eight-serving sharing format.
- Asda lists 0g sugars and 3kcal per 250ml serving.
- The drink uses sweeteners; Asda advises refrigeration after opening and consumption within three days.
R. White's
Tesco's Diet Lemonade listings describe a 2L bottle and a six-pack of 330ml cans, offering different serving formats.
- The listed products contain 2% lemon juice from concentrate; the 2L listing declares 0g sugars per 250ml.
- The listed sweeteners include aspartame, acesulfame K and saccharin, and the 2L listing carries a phenylalanine statement.
M&S
Its Diet Lemonade is an option to examine when the sweetener list matters more than a sharing-bottle format.
- Marks & Spencer lists sucralose, 2% lemon juice from concentrate, 2kcal and less than 0.1g sugars per 100g.
- Check the pack's serving information and storage instructions against the quantity needed for brunch.
Sprite
Sprite Zero is a lemon-and-lime alternative when guests are not specifically expecting lemonade.
- The Coca-Cola Company GB lists 0g sugars and 1kcal per 100ml for Sprite Zero.
- Its listed sweeteners include aspartame, acesulfame-K and sucralose; check the pack if a phenylalanine statement matters to a guest.

Questions about diet lemonade
Does diet lemonade always contain no sugar?
No. Check the sugars figure on the exact product's nutrition panel. Sainsbury's lists less than 0.5g sugars per 250ml for its Diet Lemonade, while Asda lists 0g per 250ml for its Diet Lemonade; both use sweeteners.
What if a guest needs to avoid aspartame?
Read the ingredient list and any phenylalanine statement on the pack before serving it. Tesco's R. White's Diet Lemonade listings include aspartame, while Marks & Spencer lists sucralose for its Diet Lemonade. Follow the guest's own dietary guidance rather than assuming diet lemonades have the same ingredients.
Is sugar-free fizzy lemonade harmless for teeth?
No: its sugars figure does not tell you whether it is acidic. NHS dental guidance for children says acidic fizzy drinks can cause tooth erosion and advises keeping acidic drinks to mealtimes. Serve the drink with brunch rather than offering it repeatedly between meals.
How much should I buy for a small brunch group?
Start with the number and size of the glasses you expect to serve. Sainsbury's and Asda each state that their 2L Diet Lemonade provides eight 250ml servings; allow for guests who choose another drink and for any lemonade left after brunch.
What should I do with an opened bottle?
Follow the instructions on the bottle you bought. Sainsbury's and Asda instruct shoppers to refrigerate their 2L diet lemonades after opening and use or consume them within three days.
