Organic Acids in Cacao Fermentation: Acetic, Lactic, and Succinic
Cacao fermentation is a 5–7 day microbial cascade where yeasts, lactic acid bacteria, and acetic acid bacteria transform pulp sugars into the acids that shape pH, flavor precursors, and final chocolate taste.
Cacao Polyphenols: Epicatechin, Catechin, and Procyanidins
Cacao is one of the most concentrated sources of flavanols in nature. The chemistry of epicatechin, catechin, and procyanidins — and why their structure determines their antioxidant power.
Theobromine vs Caffeine: two alkaloids, one cacao bean
They share the same molecular formula, differ by a single methyl group, and produce radically different effects. A deep dive into the two most abundant methylxanthines in Colombian cacao.
