The pisco sour is Peru’s most iconic cocktail. It combines pisco, fresh lime juice, gum syrup, egg white, and ice, then finishes with a few drops of Angostura bitters. Its balance of acidity, sweetness, alcohol, and silky foam has made it the defining drink of Peruvian cocktail culture.
It is commonly served as an aperitif in restaurants, at family celebrations, and during formal events. Although proportions vary between bars and households, one of the best-known Peruvian formulas uses three parts pisco, one part citrus juice, and one part gum syrup.
Egg white does not give the drink a pronounced egg flavor. Instead, it creates body and a stable foam that supports the aromatic bitters. The cocktail should be prepared and served immediately to preserve its temperature and texture.

Ingredients
Nutrition
- Calories: 210
Ingredients
- 180 ml pure Quebranta pisco (¾ cup or 6 ounces)
- 60 ml freshly squeezed lemon juice (¼ cup or 2 ounces)
- 60 ml simple syrup (¼ cup or 2 ounces)
- 60 g pasteurized egg whites (2 egg whites)
- 250 g ice cubes (approximately 16 cubes)
- 12 dashes Angostura bitters
Preparation
- Chill the glasses, place four small glasses in the refrigerator for at least 10 minutes. The pisco sour should be served very cold and without ice in the glass.
- Blend the base, pour the pisco, lemon juice, simple syrup, and pasteurized egg whites into a blender. Blend for 10 seconds to combine the ingredients and begin to form the foam.
- Add the ice, stir in the ice cubes, and blend for 15 to 20 seconds, until you have a cold, smooth drink with a dense foam. Avoid blending for too long, as the ice can dilute the cocktail too much.
- Serve and garnish, immediately divide the pisco sour among chilled glasses, ensuring each one receives an even layer of foam. Add three dashes of Angostura bitters to each serving and serve immediately.
Chef’s Tips
- Use quebranta pisco for the classic firm and balanced profile.
- Squeeze the lime immediately before mixing and strain the juice to remove seeds and large pieces of pulp.
- Use pasteurized egg white to reduce the risks associated with raw egg.
- Chill the pisco, syrup, and glasses in advance so less ice is required.
- Do not prepare the cocktail ahead of time because the foam loses volume and the mixture begins to separate.
- Follow the classic ratio before adjusting sweetness; too much syrup can hide the pisco’s character.
Traditional Variations
Some Peruvian bars use acholado pisco instead of quebranta. This produces a more aromatic cocktail, depending on the grapes included in the blend.
The drink may also be prepared in a cocktail shaker. The pisco, citrus juice, syrup, and egg white are first shaken without ice to create foam, then shaken again with ice before being strained.
Some household recipes replace gum syrup with dissolved sugar or regular simple syrup. Gum syrup, however, creates a smoother mouthfeel and blends more evenly.
Traditional Serving Style
Serve pisco sour in small cocktail glasses, sour glasses, or short tumblers, always without ice and immediately after preparation. The foam should cover the surface and hold three drops of Angostura bitters.
It is traditionally enjoyed as an aperitif before lunch or dinner. It is also common at celebrations, formal toasts, and family gatherings. Because its balanced sweetness and acidity soften the perception of alcohol, it should be consumed in moderation.

Did You Know?
The pisco sour developed in Lima during the early decades of the twentieth century and evolved to include egg white and aromatic bitters. Over time, it became one of the most recognizable expressions of Peruvian cocktail culture.
Its identity depends above all on pisco, a grape spirit produced in authorized regions of Peru. The citrus and syrup are not intended to hide the spirit, but to balance its strength and highlight its aroma.
Frequently Asked Questions
Peruvian quebranta pisco is the classic choice because its firm, dry, nonfloral character balances well with citrus and syrup. Acholado pisco may also be used for a more aromatic cocktail while keeping the same proportions.
Egg white is part of the most widely recognized Peruvian version and creates the characteristic foam. It also gives the drink a softer, rounder texture. For safer preparation, use pasteurized egg white and keep it refrigerated until blending.
Peruvian pisco sour is made with limón sutil, a small, aromatic citrus with pronounced acidity. Outside Peru, use a tart lime with a similar profile. Avoid pressing the peel too aggressively because its oils and white pith can add bitterness.
One widely used Peruvian formula combines three parts pisco, one part lime juice, and one part gum syrup, plus egg white and ice. This creates a strong cocktail with balanced sweetness and acidity.
It is best made immediately before serving. The citrus loses freshness, melting ice dilutes the drink, and the foam collapses quickly. Measure and chill the ingredients in advance, but blend the cocktail only when ready to serve.
