In the arid zones of the municipalities of San Nicolás and San Carlos, wild species of agave have been used for the production of mezcal for more than 300 years. The species used are A. asperrima and A. americana (both referred to locally just as “maguey”) as well as A. univittata (known as “Amole”) and A. montium-sancticaroli (known as “Jarcia”).
