Pisco Sour – Classic Peruvian Citrus & Egg White Cocktail

The Pisco Sour is a benchmark sour cocktail that combines bright citrus, smooth grape brandy, and a signature foamy texture. Built on a simple structure, it delivers a balanced mix of acidity, sweetness, and body, making it both refreshing and refined.

A South American Icon

The Pisco Sour originated in Lima, Peru, in the early 20th century and quickly became a defining drink of the region. Built using local pisco and citrus, it reflects both classic sour cocktail structure and regional identity. Today, it’s one of the most recognized cocktails worldwide.

What You’ll Need

Ingredients

• Pisco – the aromatic grape brandy base that defines the drink
• Lime juice – provides sharp, fresh acidity
• Simple syrup – balances the citrus and rounds the edges
• Egg white – creates a silky texture and stable foam
• Angostura bitters – adds aroma and visual contrast

Substitution tip: Use aquafaba instead of egg white for a similar foam, or reduce syrup slightly for a drier profile.

Equipment

• Cocktail shaker
• Jigger
• Strainer (fine strainer recommended)
• Coupe glass

Why This Drink Stands Out

The texture is what separates the Pisco Sour from other sours. The egg white softens the acidity and creates a creamy mouthfeel, turning a simple citrus cocktail into something more structured and refined.

Substitutions & Variations

• Use aquafaba for a vegan-friendly foam
• Try lemon or grapefruit for a different citrus profile
• Add a touch of passionfruit for a fruit-forward variation
• Slightly increase pisco for a stronger, more spirit-forward build

Helpful Tips

• Always dry shake hard to build a stable foam
• Use fresh lime juice for the best flavor
• Double strain for a smoother texture
• Add bitters gently to avoid breaking the foam
• Serve immediately while the foam is fresh

Safety Note

• Use fresh, properly handled eggs when making cocktails with egg white
• If unsure, substitute with aquafaba for a similar result
