Pisco Sour Recipe — A Classic Peruvian CocktailPeru and Chile fiercely contest the origin of this drink, but I was first introduced to it during my visit to Peru in 2014. Pisco, a brandy produced from distilled fermented grapes in the winemaking regions of Chile and Peru, is at the base of this drink. This recipe uses an easy-to-remember 2−1−1 ratio that ensures a balance between all the ingredients.
