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.
In April, as the female plant nears maturity a tall flower stalk or 'quiote' ('pronounced 'Kwai-O-Tee') sprouts from the centre top of the plant. This can grow up to 20 feet tall and if left to develop renders the agave useless for tequila production as the plant's energy reserves are used to grow the quiote.
