The espadín agave (agave angustifolia) is by far the most widely used agave in the production of mezcal for a variety of reasons. Among them, espadín has a relatively short maturation time, a large relative mass, a high fermentable sugar content, and perhaps most importantly, produces a great mezcal. However, espadín is also the most sustainably grown and harvested of the agaves. For these reasons, mezcal Iónico is only made from cultivated 100% agave espadín.
