Quebranta are one of the grapes commonly used in Pisco and give this spirit a fresh, grapey flavor. I’ve amplified those qualities in this refreshing cocktail with the addition of muddled grapes and Riesling wine.
- 6 seedless red grapes (halved)
- 2 ounce Pisco (preferably Quebranta)
- 1 ½ ounce Riesling
- 3/4 ounce lemon juice
- 1 barspoon simple syrup
- 4–5 medium ice cubes
- club soda (to taste)
In a sturdy, thick-bottomed pint glass from a Boston shaker, use a bar muddler to lightly crush the grapes until they burst. Add the Pisco, Riesling, lemon juice and simple syrup to the mixture; stir lightly to combine and to remove the syrup from the spoon.
Place the ice cubes into the metal part of the Boston shaker. Pour the muddled Pisco mixture (including pulp) over the ice. Cap the shaker with the pint glass. Shake vigorously until well chilled, about 20 seconds. Pour all the ingredients, including the ice, into an old fashioned glass. Top with a splash club soda.
