Ingredients

Scale
  • 1 cup fresh grapefruit juice (from 2 large grapefruits, preferably ruby red)
  • 1 bottle (750 ml) Prosecco, chilled
  • 1/4 cup rosemary simple syrup (see below)
  • 1/2 cup club soda or sparkling water
  • Ice cubes, as needed for serving
  • Grapefruit slices, for garnish (optional)
  • Fresh rosemary sprigs, for garnish
  • For the Rosemary Simple Syrup:
  • 1/2 cup granulated sugar
  • 1/2 cup water
  • 23 fresh rosemary sprigs (about 4 inches each)

Instructions

  1. Make the Rosemary Simple Syrup: Combine 1/2 cup sugar, 1/2 cup water, and 2–3 rosemary sprigs in a small saucepan. Heat over medium, stirring until the sugar dissolves.
  2. Simmer gently for 5 minutes, then turn off the heat and let the syrup steep for another 10 minutes. Strain out the rosemary and pour the syrup into a jar. Cool completely before using (about 15 minutes in the fridge).
  3. Juice the Grapefruits: Cut 2 large grapefruits in half. Use a handheld citrus press or electric juicer to extract about 1 cup juice. Strain the juice with a fine mesh strainer to remove pulp and seeds.
  4. Mix the Cocktail: In a large pitcher, combine the grapefruit juice, 1/4 cup rosemary syrup, and 1/2 cup club soda or sparkling water. Stir gently until well blended.
  5. Fill glasses with ice cubes (about 4–5 cubes per glass). Pour the grapefruit mixture evenly into glasses, filling each halfway.
  6. Top each glass with chilled Prosecco (about 3 oz per glass). Pour slowly to preserve the bubbles.
  7. Garnish and Serve: Garnish each glass with a thin grapefruit slice and a fresh rosemary sprig. Serve immediately while cold and bubbly.

Notes

Chill all ingredients before mixing for maximum fizz. Adjust syrup to taste depending on grapefruit sweetness. For a non-alcoholic version, substitute Prosecco with sparkling cider or kombucha. Make syrup ahead and store in the fridge for quick cocktails. Don’t let the cocktail sit too long with ice to avoid dilution.
