Pack a wine glass with ice, then measure the pomegranate juice into the spaces between the cubes. The juice should collect around the ice in a deep ruby pool.

Pour the prosecco slowly against the inside of the glass, follow with the Aperol, and finish with club soda. A rising stream of bubbles and a lighter crimson color signal that the sparkling liquids have joined the juice.

Set the orange slice at the rim or among the ice and scatter the pomegranate arils into the glass. The garnish should bring fresh citrus aroma and ruby accents to the finished drink.
