A balanced cordial base for creating house-made fruit, herb and botanical cordials.

What is a Cordial?

Cordials are one of the most useful building blocks behind the bar. At their simplest, they are sweetened and acid-balanced syrups designed to carry flavour. Unlike a standard sugar syrup, a cordial combines sweetness, acidity and aromatics into a single ingredient, allowing bartenders to build complexity, consistency and balance into drinks with minimal effort.

From classic lime cordials and elderflower cordials to more contemporary fruit, tea and botanical creations, cordials can be used to introduce flavour, provide sweetness, contribute acidity, or achieve all three simultaneously. They are equally valuable in cocktails, low-alcohol serves and non-alcoholic drinks.

Building a Balanced Cordial

While flavour is often the focus, balance is what makes a cordial successful. Sugar provides body and sweetness, while acids bring brightness, freshness and structure.

In this recipe, we combine citric and malic acid rather than relying on citric acid alone. Citric acid delivers the sharp, clean acidity associated with citrus fruits, while malic acid contributes a softer, longer-lasting tartness found naturally in apples and many orchard fruits. Together they create a fuller, more natural acidity that helps flavours feel vibrant and well-defined.

This base cordial provides a versatile foundation that can be adapted with fresh juice, fruit purée, infusions or extracts to build a wide range of bar cordials.

Ingredients

Method

Warm the water gently and add the sugar, stirring until completely dissolved. 

Add the citric and malic acid and stir until fully incorporated. 
Allow the cordial to cool before bottling and store refrigerated.

Cordial Applications: Elderflower

One of the most classic applications of a cordial is elderflower. A fragrant floral cordial that uses a small amount of lemon oil to support the natural citrus notes of the flower and helps the flavour carry through. A cordial that works beautifully in Spritzes, Collins and Light Highballs.
Though this is our chosen example here, the same base cordial can be used alongside other seasonal fruits, herbs, teas, spices and botanical ingredients to create bespoke house cordials.

Notes

Citric and malic acid levels of the Base Cordial can be adjusted depending on the desired style of acidity. Increasing citric acid creates a brighter, citrus-led profile, while increasing malic acid creates a softer, longer-lasting tartness.
