A light, citrusy and herbal warm weather variation on the classic Negroni, with Aperol standing in for Campari, and Cocchi Americano for the sweet vermouth.
Fill a mixing glass with ice. Add gin, Cocchi Americano, and Aperol. Stir well. Strain into an ice-filled old fashioned glass. Twist grapefruit peel over drink to express oils, add to cocktail and serve.
