Tried with spanish pomelo instead of grapefruit... I think it wasn't such a good idea. Next time I'll try it with proper grapefruit !
Probably not my favourite mezcal cocktail anyway.
Interesting; very interesting combination of flavors. Campari's characteristic bittersweet collides with the smokey bitters from the mezcal (I used Apaluz, wild grown and sustainably harvested Agave Durangensis), and the pony kicked back. Indeed the grapefruit juice contributed some bitter/sours as well and the whole thing works 'cause it's so boozy.
