Maguey Alto is a sub-species of agave Inaequidens. The term Inaequidens means “uneven teeth,” which is applicable to this agave as the teeth of the pencas are uneven and jagged. All of the sub-species of this agave family are rarely used in mezcal or raicilla. Maguey Alto grows wild in the state of Michoacan. It’s a massive agave, taking over 15 years to mature. It’s also very low-yield, which is one reason why it’s so seldom used. One 500 kilo pina from a plant will only yield about 6 litres of mezcal.
