Made it with Milagro Reposado; no Punt e Mes so used Alessio Rosso, which was great in this drink and works well with Difford's chocolate garnish suggestion. Squares of chocolate do not skewer well on toothpicks or cocktail swords and a square of chocolate at the bottom of a cocktail glass looks more like a mistake than a garnish so I did something I've done before (e.g., "Munich Negroni Western Style") and grated a light dusting of chocolate over the drink, which enhances the nose as well.
