Classic Whiskey Sour Cocktail – Bourbon, Lemon & Simple Syrup
The Whiskey Sour is one of the most famous sour cocktails, combining bourbon, fresh lemon juice, and simple syrup for a perfectly balanced drink. Smooth, bright, and refreshing, this classic cocktail has remained a bar staple for more than a century.
The Whiskey Sour is a cornerstone of classic cocktail culture. Built on the simple formula of spirit, citrus, and sweetener, it delivers a perfect balance of bold bourbon, bright lemon, and smooth sweetness. When shaken with egg white, the drink gains a silky foam and velvety texture that elevates it from a simple sour to an elegant cocktail.
Background
The Whiskey Sour dates back to the mid-1800s and was first recorded in Jerry Thomas’ famous bartending guides. Sailors had long mixed citrus with spirits to prevent scurvy, and bartenders eventually refined the idea into the sour cocktail template. Today the Whiskey Sour remains one of the most widely recognized drinks in the world and a foundation of modern mixology.
