Quite good! This will be sensitive to the specific mezcal used. I used Mal Bien 100% Espadin and it worked well. This is an artesanal but fairly tame mezcal. For everyday use I usually use Bulleit "95" rye but for this I used A.Overholt "Monongahela Mash" straight rye (95 proof, 80% rye, 20% barley malt, non-chill-filtered).
