Fermentation and Coffee processing

Fermentation is the key to understand and control these processing methods. Coffee is a kind of fruit, like most fruits, it is rich in nutrients, sugars and other compounds. These compounds exist in the mucus and shell of coffee fruit, providing a good environment for bacteria and other microorganisms to reproduce.

Fermentation is a process in which microorganisms digest these nutrients, release gases and calories, and decompose the original nutrients into other compounds. This means that all of these coffee processing methods involve a certain degree of fermentation.

Christina Wright de Castro Borges, CEO of Ipanema Coffee, told me that fermentation always affects the taste of coffee, but the change is not necessarily positive. "you want to stimulate the fermentation process, but reach the desired level and avoid excessive fermentation so as not to adversely affect the appearance of the drink," he said. "

Good and bad coffee fermentation

Rodrigo Ferreira Rodriguez is the industrial director of Ipanema Coffee. "through good fermentation, you can make the nuances of coffee more obvious, so you can drink fruity coffee and you can drink more alcoholic coffee," he said. "

He added: "if these features are good, then you can take full advantage of the taste of these fruits." The taste of these fruits can be yellow or red. "

On the other hand, if the fermentation is not controlled, there will be a bad taste in the cup. Rodrigo describes them as "rotten, even sour", like "rotten fruit".
