Pisco supplies the grape aroma in this simple sour, with lemon juice providing acidity and granulated sugar balancing the citrus. This version contains no egg white, so it has a lighter surface and less foam than an egg-white sour. Shake until the sugar has dissolved and the mixture is thoroughly chilled.
