PRACTICAL WALKTHROUGH · PARAMETERS · COMMON MISTAKES
Cacao bean fermentation followed by stone grinding transforms raw beans into flavor precursors and a paste suitable for chocolate production.
Origin: Maya, Aztec, Andean, Amazonian (Pre-Columbian) — Mesoamerica, Andes, Amazon Basin
See full technique reference →During fermentation, lactic‑acid bacteria lower the pH, yeasts produce ethanol, and thermophilic bacteria convert sugars to CO₂ and organic acids, generating a complex aroma profile. Stone grinding mechanically reduces particle size, increasing surface area for cocoa‑butter extraction while maintaining low temperature to prevent oxidation of polyphenols.
Primary Reaction
Microbial conversion of sugars to organic acids, ethanol, and CO₂ during fermentation
