Take a cocktail shaker or a cocktail mixing glass- anything which is easily available.
Add Bourbon, Cappelletti, Lemon Juice, and Green Chartreuse in the shaker or mixer.
Add 2-3 tablespoons of ice and stir the ingredients together-until cold.
Strain the cocktail into an ice-filled lowball or a wine glass.
Optional: To garnish the cocktail you can add Lemon Wedge or mint on the top of the cocktail.
