For each Grapefruit Prosecco Cocktail:

  • 1/2 oz (1 tbsp) rosemary simple syrup (see recipe below)
  • 2 oz (1/4 cup) freshly squeezed ruby red grapefruit juice
  • About 4 oz prosecco

Rosemary Simple Syrup:

  • 1/2 cup sugar
  • 3/4 cup water
  • 1 rosemary sprig


  1. To make the rosemary syrup, combine the sugar, water and rosemary in a small saucepan. Bring to a simmer, stirring to dissolve the sugar. Once dissolved, remove from heat. Cover and allow to cool before straining in to a container with a lid. Store in the refrigerator.
  2. To make a cocktail, add 1/2 oz of rosemary syrup and 2 oz freshly squeezed grapefruit juice to a glass. Top with prosecco and garnish with rosemary.


For a large batch (about 6 drinks):

  • 12 oz (1 1/2 cups) freshly squeezed ruby red grapefruit juice (from about 1 1/2 to 2 large grapefruits)
  • 3 oz (6 tbsp) rosemary syrup
  • 1 bottle prosecco

Juice and syrup can be prepared a day or two in advance. To make a large batch, you can mix the grapefruit juice and syrup ahead of time. Then just pour 2 1/2 ounces of the mixture into each glass and top with prosecco when it's time to serve.
