Whiskey Sour Recipe: Classic & Easy

At its core the whiskey sour is just three things: whiskey, lemon, and sugar. What separates a great one from a flat one is fresh juice, the right proportions, and the optional egg white that gives it that signature silky foam. Here's the classic build, plus how to make it your own.

Classic Whiskey Sour Recipe

Ingredients:

• 2 oz bourbon
• 3/4 oz fresh lemon juice
• 3/4 oz simple syrup
• 1/2 oz egg white (optional, for foam)
• Angostura bitters and a cherry, to garnish

Instructions:

1. Add the bourbon, lemon juice, simple syrup, and egg white (if using) to a shaker without ice.
2. Dry-shake hard for about 15 seconds to build the foam.
3. Add ice and shake again until well chilled.
4. Strain into a rocks glass over fresh ice (or up into a coupe).
5. Garnish with a few drops of bitters and a cherry.

Choosing Your Bourbon

A whiskey sour rewards a flavorful, mid-proof bourbon that can stand up to the lemon. Buffalo Trace and Maker's Mark are reliable, well-priced choices. If you want to make it special, a single barrel like Eagle Rare adds real depth, see our Eagle Rare Whiskey Sour for that premium build.

Tips & Variations

Always use fresh lemon juice; bottled juice is the fastest way to ruin a sour. The egg white is optional but worth it for the texture and looks; aquafaba (chickpea brine) works as a vegan substitute. Swap bourbon for rye for a spicier, drier sour, or add a float of red wine over the top to make a New York Sour.
