Agave Arroqueno (americana var. oaxacensis) is a massive wild agave that can take upwards of 20 years to mature. It is the genetic mother of agave Espadin, which is the most commonly used agave in Mezcal. Many in the Mezcal industry are concerned that this wild agave will become more and more rare as Mezcal’s popularity rises, because of the extensive time required for these agave to grow. Fortunately, most (not all) producers using agave Arroqueno do so responsibly. Most are careful not to over-harvest. A few Mezcal producers are also doing sustainability projects to plant new Arroqueno in the Oaxacan hills to replace those harvested each year.
