Maguey Tepeztate (Tepextate) is part of the agave Marmorata family and has a strange and arbitrary leaf pattern. One sometimes sees pictures of the flower stalks, because they are so beautiful. Big flower with a rich and very intense yellow colour.
Tepeztate takes as many as 25 years to mature, which is why mezcals based on this particular agave species is expensive. Farming the agave is also quite difficult, as it need very rocky terrain. The masculine taste however, is worth it.
