How big is it too big? When does a mezcalero stops being "small batch" and migrates to something that could be labeled as not truly artisanal? In this conversation with jóven Jon Darby (patrón at @sin_gusano) we dabble around some some of these questions, while sipping some rarities, that according my invitee prove that he may not be the worst purist in this industry. I hope you enjoy this one.
