Cordial Dilution Calculator

Most cordials and squash recommend a 1:4 ratio — one part cordial to four parts water. This means for a 250ml glass, you would use 50ml of cordial and 200ml of water. Some brands recommend 1:5 or even 1:9.

In the UK, squash is a concentrated fruit drink that you dilute with water. Cordial is similar but often higher quality, made with more real fruit juice and sugar. Squash is typically diluted at a higher ratio (1:5 or 1:9) because it is more concentrated.

For a two-hour event, plan for 2-3 glasses per person. Using the calculator, enter the total number of servings you need and it will work out the cordial and water quantities. A 500ml bottle of cordial typically makes about 2.5 litres of diluted drink.

Yes, adjust the dilution ratio to suit your taste. A 1:3 ratio gives a stronger drink, while 1:5 or higher gives a lighter one. The calculator supports custom ratios so you can match your preference exactly.

Most UK cordials recommend a 1:4 or 1:5 ratio (one part cordial to four or five parts water). However, this varies by brand and personal preference. Elderflower cordial is typically 1:10 as it is very concentrated. Taste and adjust — the recommended ratio is a starting point, not a rule.
