Harvesting Agave for Tequila. I n the past, agave were harvested when the jimadors decided they were ripe enough. This was generally done when the agaves were from eight to ten years old. Jimadors knew, from generations of experience, when the agave was ripest, when it was rich with sugars and ready for harvesting.
The genus Agave is part of the family Agavaceae. There are around 200 species in the genus. Most of these are from Mexico, although they occur in the southern United States and into South America. Plants are characterized by forming rosettes of fleshy (succulent) leaves which have a sharp point or spine terminally. The leaf margins may be smooth or spiny. Agave plants have been given the common name Century Plant because of their blooming habit. The idea is that the plants live for 100 years, bloom and die. While it is true that Agave are monocarpic, meaning they bloom once and then die, few species, if any, take a full 100 years to do this.
