Coffee cherry will produce fermentation in the process of sun-drying. fermentation is the time when coffee beans produce chemical changes to produce more flavor. from the past to the present, coffee factories continue to try different fermentation methods. by controlling the source of fermentation (anaerobic fermentation), adding raw materials to feed bacteria, through different sugar sources and sugar content, using different substances such as fruit paste, cola and alcohol to change the fermentation bacteria and create different flavors. For example, the addition of cola is said to produce the taste of cardamom and cinnamon.
