• Fill a large wine glass or spritz glass generously with fresh ice cubes.
• Pour 1/2 ounce of your prepared cherry simple syrup over the ice.
• Add 1 ounce of Aperol to the glass.
• Pour in 3 ounces of chilled Prosecco.
• Top the glass with 1 ounce of Fever-Tree sparkling grapefruit mixer.
• Stir gently with a long bar spoon from the bottom of the glass to combine the layers without losing carbonation.
• Garnish with a fresh cherry and a slice of grapefruit, then serve immediately.

Cherry Syrup

• Add the sugar, water, and pitted cherries to a small saucepan over medium heat.
• Bring the mixture to a boil, stirring occasionally until the sugar dissolves completely.
• Reduce the heat to low and let it simmer for 10 minutes, using a spoon to mash the cherries gently.
• Remove the pan from the heat and let the syrup cool completely to room temperature.
• Pour the syrup through a fine-mesh strainer into a clean jar to remove the fruit pulp, then store it in the fridge.
