Fermentation in coffee: the basics

As we saw earlier, the coffee treatment process "only" serves to pulp the coffee cherry to obtain a bean with a moisture content suitable for storage and delivery. Whatever the process used to treat the coffee cherry, there is always a fermentation stage.

What interests us today is controlled fermentation. We'll look at 3 basic types of fermentation: carbonic maceration, aerobic fermentation and anaerobic fermentation.

The little green beans we use to bring you the black gold you love so much are not so easy to obtain. It's on farms, often on the other side of the world, that the coffee cherry is transformed into a green bean ready for shipment.
