What You Need to Know
Convective heat transfer in stone-lined pits (horno de tierra) induces Maillard reactions and caramelization of agave fructans, while smoldering mesquite wood generates phenolic compounds like guaiacol and syringol that permeate the plant tissue.
The foundational step that differentiates mezcal from tequila, creating the spirit's characteristic smokiness through direct contact with hot stones and wood embers.
