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.
Some of us are just (really) late bloomers. (Mike Householder/AP) American agave plants are known for their fairly fatalistic life cycles: live, die, repeat. After blooming, the plants are expected to die shortly thereafter, usually leaving behind clones of themselves in the form of seeds. But the plant at the University of Michigan's Matthaei Botanical Gardens adds yet another layer of intrigue to the American agave's story line. This particular agave grew to be 28 feet tall and blew past its 25-year life expectancy by waiting a full 80 years to finally bloom. Now, it's finally dying.
