I bought some fernet branca on a whim before Christmas and it was an inspired experiment. Between this (5* for me) and The Ferrari (equal parts Fernet and Campari) my digestif needs were sated. This cocktail is delicious, but it kinda tastes like tempered Fernet - I don't get much tequila (I've used both Olmeca and Madre mescal and a combination). Am I wasting good stuff on it?
