Adios my friend

Combine the blanco tequila, mezcal, sotol, bacanora, curaçao, and Luxardo Bitter Rosso in a mixing glass filled with ice.

Stir the mixture until well chilled and fully integrated.

Strain the cocktail into an Old Fashioned glass over a fresh ice cube.

Express the oils from a grapefruit peel over the drink, then drop the peel into the glass as a garnish.
