What You Need to Know
During roasting, Maillard reactions between amino acids and reducing sugars produce melanoidins and flavor compounds, while fermentation converts sugars to lactic acid, ethanol, and volatile aroma molecules. The mechanical grinding releases cocoa butter, forming a stable emulsion that gives the beverage its characteristic smooth texture.
