Pour 1.5 oz hibiscus syrup into the bottom of the glass.
Tilt the glass and pour in 4.5 oz chilled sparkling wine slowly, watching the color spread from the bottom up.
Stir once, gently.
Drop in a dried hibiscus flower; it will slowly open as it sits in the bubbles.
Serve right away.
Good to Know
No hibiscus syrup in the store? Steep 1/4 cup dried hibiscus flowers in 1 cup hot simple syrup for 10 minutes, strain, and cool completely before using.
