Fill a mixing glass with ice. Top with cranberry-infused Altos Blanco Tequila, Lustau White Vermouth, Aperol and orange-blossom water. Stir to chill. Strain into a rocks glass, add a large ice cube and garnish with grapefruit zest.
Notes
To make cranberry-infused tequila, add 150 g of wild bog cranberries that have had their skins split to 750 mL of Altos Blanco Tequila. Let stand at room temperature for 48 hours. Strain and store in the fridge.
