Description
Traditional pit-roasting of agave hearts (piñas) imparts signature smoky flavors through controlled pyrolysis before fermentation and distillation.
Technical
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.
Culinary Significance
The foundational step that differentiates mezcal from tequila, creating the spirit's characteristic smokiness through direct contact with hot stones and wood embers.
