Grapefruit Whiskey Sour

Total Time: 25 minutes
Yield: 2


  • 4 ounces of your favorite whiskey
  • 6 ounces fresh grapefruit juice
  • 1 cup water
  • 1 cup granulated sugar
  • 4 sprigs of fresh rosemary, plus extra for garnishes
  • 12 ounces of club soda
  • Round lemon slices


  • Make a grapefruit-rosemary soda. To do this, first make a rosemary simple syrup by bringing the water, sugar, and rosemary sprigs to a boil in a pot. Let the mixture cool to room temperature and then strain out the rosemary sprigs. Set aside.
  • In a large pitcher, combine the grapefruit juice, club soda, and 1.5 ounces of the rosemary simple syrup and stir.
  • Split the whiskey between two cups filled with ice. Top off with the grapefruit-rosemary soda. Garnish with leftover fresh rosemary and the lemon wheels. Cheers!
