Pisco, a distilled grape brandy, is the Peruvian national liquor. Arguably the most popular way to drink pisco is mixed into a Pisco Sour, the famous national cocktail. The most classic version of this drink combines pisco with key lime juice, syrup, ice, egg white, and angostura bitters. You will find Pisco Sours nearly anywhere you go in Peru, and you may well encounter the cocktail in bars around the world. However, it all began in Lima. The Pisco Sour was first created in the 1920s at the Hotel Maury Bar in Downtown Lima, which is still an symbolic place to enjoy the beverage.
