A bright and elegant brunch punch combining fresh grapefruit juice, sparkling water, and a subtle rosemary infusion. Perfect for crowds and easy to prepare in about 10 minutes.
Add sparkling water just before serving to maintain fizz. Steep rosemary briefly to avoid overpowering flavor. Use large ice cubes to slow dilution. Prepare rosemary infusion and juice ahead to save time. Store juice and syrup mixture separately from sparkling water for up to 2 days in the fridge.
