Hosts serving several guests
A cordial lets you mix glasses individually and adjust their strength. Check the bottle’s dilution ratio when working out how much sparkling water you will need.
Who is each option for?
Shoppers who want a sparkling drink without mixing
A ready-to-drink option can be chilled and served as it is. If you need a non-alcoholic drink, confirm that description on the specific product label rather than assuming it applies to every sparkling drink.
Households checking ingredients for guests
Read the current package before serving someone with an allergy or intolerance. Ingredients and allergen statements can differ between flavours, even within one cordial range.
What should you check before buying?
Cordial with sparkling water
Choose it when: You want to vary the strength between glasses or prepare several drinks from one concentrate.
Allow for: Separately supplied sparkling water and the time to mix each drink.
Ready-to-drink sparkling drink
Choose it when: You want to chill the drink and serve it without measuring cordial.
Allow for: A finished drink whose dilution cannot be adjusted by the glass.
| Priority | What to check | Your needs |
|---|---|---|
| Sparkling serve | For cordial, look for an explicit sparkling-water instruction. Follow the ratio on that bottle: Waitrose & Partners lists 1:10 for Belvoir Elderflower & Rose, while its No.1 Elderflower listing suggests one part cordial to four parts water. | I want a fizzy drink, but I also want to control how strong each glass tastes. |
| Nutrition basis | Check whether nutrition is stated for concentrate or a prepared drink, and compare sugar figures on the same stated basis. A stronger mix changes the amount of cordial poured into a glass. | If I am comparing sugar figures, I need to know what quantity and preparation they describe. |
| Ingredients | Read the current package for ingredients and declared allergens, including sulphites where relevant. Check the exact flavour rather than relying on another product in the range. | A guest may need to avoid a particular ingredient, so I need to check the drink I will actually serve. |
| Storage | Check whether the opened bottle needs refrigeration and when its label says to use it. Ocado’s M&S Elderflower Cordial listing, for example, says to refrigerate after opening and consume within two weeks. | I may have cordial left after the film and want a bottle size I can use within its stated period. |
Common mistakes to avoid
-
Assuming cordial is already fizzy
A cordial is a concentrate, so making a sparkling drink also calls for sparkling water.
Choose a bottle whose directions explicitly permit sparkling water, then follow its stated ratio and have enough sparkling water for your guests.
-
Comparing unlike sugar figures
A figure for diluted cordial does not describe the concentrate poured straight from the bottle.
Check the preparation and quantity behind each figure before comparing drinks, and use the stated dilution when assessing a prepared glass.
-
Relying on an older ingredient listing
A guest’s suitability depends on the ingredients and allergens of the specific drink being served.
Read its current physical label, particularly if someone needs to avoid sulphites or another ingredient.
-
Buying more cordial than you will use
Opened-bottle refrigeration and consume-within instructions vary by product.
Check the period on your chosen bottle before deciding on a flavour and size.
Cordial left beyond its stated opened-bottle period may go unused.

Questions about serving and storage
Can I mix cordial with sparkling water?
Yes, if the particular cordial’s directions permit it. Waitrose & Partners lists water or sparkling water for Belvoir Elderflower & Rose and Raspberry & Lemon, and suggests sparkling or still mineral water for its No.1 Elderflower and Ginger cordials.
Should I choose cordial or a ready-to-drink sparkling drink for movie night?
Choose cordial when you want to adjust each glass and prepare multiple drinks from a concentrate; you will also need sparkling water if you want them fizzy. Choose a ready-to-drink sparkling drink when serving without mixing matters more.
How much cordial goes into a glass of sparkling water?
Follow the ratio on your exact bottle. Waitrose & Partners lists 1:10 for the cited Belvoir cordials, while its No.1 Elderflower and Ginger cordials suggest one part cordial to four parts water; neither ratio applies to every cordial.
How should I store cordial after opening?
Follow the chosen bottle’s refrigeration and consume-within instructions. For example, Ocado’s M&S Elderflower Cordial listing says to refrigerate it after opening and consume it within two weeks; another cordial may have different directions.
What should I check before serving a guest with an allergy?
Read the current package’s ingredient and allergen statement for the exact flavour before serving it. Check for sulphites where relevant, and do not assume that another flavour from the same brand has the same ingredients.
