I split the base to 1/4 Oz. mezcal (Del Maguey Vida) and 1 1/4 Oz. tequila (Espolon Reposado) as I wasn't in the mood for a strongly smoky drink. This worked really well. Grapefruit bitterness follows a light spicy, smoky entry with sweet tequila providing the background. A nice, refreshing aperitif with enough complexity to keep it interesting.
