The coffee beans are treated after harvest, otherwise they will begin to ferment, making the coffee beans smell bad. The main treatment methods are "drying" and "washing", these two methods will cause different flavors. Dry beans have a complete natural mellow, gentle aroma and more gum, while water washing has a good mellow taste, high aroma and lively sour taste, which is also the source of sweetness in espresso.

Dry type

The method is relatively simple. First of all, spread the freshly harvested fruit on the sun field for a week or two until the fruit crackles and dries naturally. After that, the dried pulp, endocarp and silver peel are removed by a sheller.

Coffee beans refined in this way are slightly sour and slightly bitter. Almost all coffee beans produced in Brazil, Ethiopia, Yemen and other places are obtained in this way. The disadvantage of this method is that it is easily affected by the weather and is easy to be mixed with defective beans and other impurities. Therefore, it must be carefully screened.

Washing type

The fruit that is about to be harvested is put into a flowing trough. After the floating fruit is removed, the skin and flesh are removed by a pulp remover. Then put it in the sink to remove the emerging pulp. After that, move into the fermentation tank, soak for half a day to a day, and then dissolve the gum on the surface of the fermented coffee beans.

After washing with water, drying it for a few days, drying it with a machine, and finally using a sheller to remove the endocarp to become a commercial raw coffee bean. In this way, it will be more beautiful in color and less impurity than dried coffee beans. About 70% of the production in Colombia, Mexico, Guatemala and other countries uses this method to remove the skin, pulp, racing peel and silver skin before shipping the fruit. There are two kinds of methods: drying (also known as natural or non-washing) and washing.
