The three-phase microbial succession of cacao fermentation — yeast, lactic acid bacteria, acetic acid bacteria. How bean death triggers protein hydrolysis and creates the Maillard precursors that make chocolate possible.
The Criollo/Forastero/Trinitario classification is scientifically obsolete. Here's what the 2008 Motamayor study actually found, why it matters for flavor, and what craft chocolate makers should know about cacao genetics.
The volatile compounds that create chocolate flavor — pyrazines, Strecker aldehydes, furans, linalool, and more. How fermentation creates precursors and roasting assembles them into the 68 compounds identified by GC-MS.
The six crystal forms of cocoa butter, triglyceride composition (POS/SOS/POP), fatty acid profile, why Form V is the target, the bloom transition to Form VI, and how cocoa butter alternatives work.
The complete arc of chocolate history — from the earliest archaeological evidence in Ecuador, through Mesoamerican ritual use, European transformation, industrial revolution, and the modern craft revival.
