Refugio Calzada, or Don Cucu as he's known to friends, was the president of a local association of mezcaleros (mezcal producers) and magueyeros (agave farmers) for many years and has been a driving force behind agave and tree reforestation efforts that have helped make agave more plentiful than they were in his youth. This batch of his Papalote was rested for 3 years in glass before its release, which has mellowed out the intensity of the flavor and texture compared to his joven batches.
