2 ounces Don Julio, El Tesoro, Milagro, or Partida Blanco Tequila

Pour the tequila, Aperol, crème de cacao, and lemon juice into a mixing glass. Release the oils from 3 of the grapefruit twists into the glass by gently twisting them, then add them, along with lots of ice, to the glass. Shake for approximately 15 seconds, strain into a chilled champagne flute, and add the remaining grapefruit twist as garnish.
