Combine water, rosemary sprigs, and sugar in a small saucepan. Bring to a boil and stir until sugar is dissolved. Remove from the heat and let cool for 10-15 minutes. Strain and discard the rosemary. Chill rosemary-syrup until ready to use.

Fill a cocktail shaker half full of ice. Add ½ cup grapefruit juice, 1/3 cup gin and 2 TB rosemary-syrup. Shake well and strain into two champagne flutes. Top each with a 2 TB float of sparkling wine. Repeat 3 more times to make all 8 cocktails.
