Casamigos Mezcal is made using the traditional method. Once harvested, the piñas are split and laid to cook for 4–6 days in six-ton earthen pits lined with volcanic rock. Piñas are cooled for 24 hours before the crushing process begins. The agave is crushed & then Casamigos Mezcal ferments for 2–8 days before being distilled in covered copper pot stills.
