Whiskey Sour

The Whiskey Sour belongs to the classic sour family of cocktails, built around the simple combination of a spirit, citrus juice and a sweetening ingredient. Whiskey-based sours became popular during the nineteenth century as bartenders developed this versatile formula.

Early Whiskey Sour recipes relied on whiskey, fresh lemon and sugar, often served without the foamy topping associated with many modern versions. Over time, the addition of a foaming ingredient became a popular variation, creating a smoother texture and distinctive presentation.

Today, the Whiskey Sour remains a classic cocktail enjoyed with bourbon or rye whiskey. Its straightforward combination of rich whiskey, bright citrus and balanced sweetness has also inspired variations such as the New York Sour, which adds a red wine float.

A balanced bourbon whiskey is the ideal foundation for a classic Whiskey Sour. Look for a bourbon with enough vanilla, caramel and oak character to remain noticeable alongside the fresh lemon. Bourbon creates a rounded, slightly sweet cocktail, while rye whiskey offers a spicier, drier alternative.

Use freshly squeezed lemon juice for bright acidity and a clean citrus finish. Fresh lemon is particularly important in a Whiskey Sour because the citrus plays such a prominent role in the flavour.

A good cane sugar syrup provides consistent sweetness and blends easily with the other ingredients. It allows you to adjust the cocktail's balance without introducing unwanted flavours.

For a silky foam without egg white, use Fee Brothers Fee Foam. Three dashes in the shaker help create a smooth, aerated head when the cocktail is dry shaken and then shaken again with ice.

Aromatic bitters are optional, but two dashes can add extra spice and complexity. They can be shaken with the other ingredients or used sparingly as a finishing accent on the foam.

The key to a well-balanced Whiskey Sour is finding the right relationship between bourbon, fresh lemon and sugar syrup. Our recipe uses 50 ml bourbon, 25 ml lemon juice and 20 ml cane sugar syrup, creating a bright, refreshing cocktail that still retains the whiskey's rich character.

If your Whiskey Sour tastes too sour, add a little more sugar syrup. If it is too sweet, increase the lemon juice slightly. The sweetness of the syrup and the acidity of fresh lemons can vary, so small adjustments may be necessary.

Proper dilution matters too. Shake firmly with ice until thoroughly chilled, but avoid excessive shaking that makes the cocktail watery. A good Whiskey Sour should taste smooth and balanced, with the bourbon, citrus and sweetness working together rather than competing.

A smooth foam gives the Whiskey Sour its distinctive silky texture and elegant appearance. For an egg-free version, add 3 dashes of Fee Brothers Fee Foam to the shaker along with the bourbon, fresh lemon juice and sugar syrup.

Start with a dry shake, shaking vigorously without ice for approximately 10 seconds. This begins aerating the mixture and helps incorporate the foaming ingredient.

Next, add 150 g of ice and shake firmly for another 10–12 seconds to chill and dilute the cocktail. Double strain into a chilled coupe or rocks glass, allowing the foam to settle into an even layer across the surface.

For the best presentation, serve immediately while the foam is fresh and stable. The cocktail should have a light, creamy head rather than a thick, stiff foam.
