What is the most common base for a Pisco Sour?

The most common base for a Pisco Sour is indeed Pisco, which is a type of brandy produced in the wine-making regions of Peru and Chile. The cocktail is distinguished by its light and refreshing flavor profile, achieved by combining Pisco with lime or lemon juice, simple syrup, egg white, and bitters.

Pisco serves as the foundation of the drink, contributing its unique aromatic and fruity qualities that define the essence of the Pisco Sour. The characteristics of Pisco, which include floral and fruity notes, are essential for balancing the acidity of the citrus juice and the sweetness of the syrup, resulting in a harmonious beverage.

Other spirit options mentioned, such as rum, vodka, and tequila, do not align with the traditional recipe of a Pisco Sour and would fundamentally alter the drink’s signature flavor and identity. Each of these spirits has distinct flavor profiles that do not match the intended profile that Pisco brings to this celebrated cocktail.
