Aguerrido Cupreata from Refugio Calzada Hernandez is produced in Tetitlan de la Lima, Guerrero using Agave cupreata. Don Refugio cooks his agave in a pit oven, mills the cooked agave using a shredder, ferments the agaves with open air yeasts, and double distills in a copper alembic still. 

Mezcal Aguerrido is a brand that comes from the heart of the state of Guerrero, one of the least represented mezcal producing states due to the difficulties with narco-traffickers in the area. The brand is a union of maestros mezcaleros from Chilapa, Guerrero including Don Refugio, Don Ciro (R.I.P.), Don Tomás, Don Benigno, Dona Gabina, y Don Antonio.
