How to Make It
Fill a rocks glass with ice. Pour the Carpano Antica over the ice and top with the club soda or seltzer. Stir, then garnish with the bitters and mint sprig.
Variation: For a more bitter, boozier drink, make this recipe with amaro instead of Carpano Antica, using the same proportions. For an intensely bitter amaro, try Luxardo Fernet. For something sweeter, try the earthy Amaro CioCiaro or the minty S. Maria al Monte.
