Mezcal Artesanal Premium de Guerrero. Mezcal Burero is produced in the small town of Mochitlan in Guerrero, Mexico, using 100% hand-harvested maguey. Harvesting our maguey by hand, fermentation is a natural process in vats made from ayacahuite wood using traditional techniques and double distill it in a copper still, which gives it a unique smoky and earthy flavor.
