Cocoa Fermentation: Transforming Bitter Seeds into Flavor Precursors

Factors That Shape Fermentation Quality

A all fermentations are equal. Bean type matters: Forastero beans, with their thicker pulp and higher polyphenol content, typically require five to seven days and tolerante more intense aqualication, while Criollo beans - prized for their delicate flavor - ferment faster (two tre days) and are easyily overfermented.
