Fósforo Tobalá is produced by mezcalero Aarón Alva Sánchez San Nicolás Huajuapan, Puebla using cultivated Maguey Tobalá which grows for 8-15 years. The harvested plants are cooked underground for 5-8 days, shredded, and then naturally fermented for 10-14 days in open-air wooden vats. The pulp and liquid are then double-distilled in copper pots. This Tobalá is bottled at 45% ABV. (Font: mezcalreviews.com)
