Maguey Sierrudo (also spelled Cerrudo) most commonly refers to a maguey in the agave Americana family. This means that it is closely related to maguey Arroqueno, Sierra Negra, and Coyote. This agave is enormous. It generally takes 16-20 years to mature and can grow up to 1,000 pounds in weight. There are some regions, however, that use the name Sierrudo to describe an Agave Rhodacantha.
