The Peruvian Pisco Sour
The official cocktail of Peru. It uses Peruvian pisco as the base liquor and adds Key lime juice, syrup, ice, egg white, and Angostura bitters. Pisco is a brandy produced in winemaking regions of Chile and Peru.
The cocktail originated in Lima, Peru, and was invented by Victor Vaughen Morris, an American bartender, in the early 1920s. Chile and Peru both claim the Pisco Sour as their national drink, and each asserts exclusive ownership of both pisco and the cocktail; consequently, the Pisco Sour has become a significant and oft-debated topic of Latin American popular culture.
