Coffee Processing MOC¶

Coffee processing transforms freshly harvested cherries into stable, exportable green beans, and the chosen method profoundly shapes the final cup's flavour profile — often more dramatically than origin or variety alone. The three principal methods — washed, natural, and honey — differ in how much of the fruit remains in contact with the seed during drying, governing the fermentation activity and compound transfer that define each method's characteristic cup character. This MOC maps all processing knowledge from traditional methods through modern fermentation-focused innovations.
