Most of Mantenin in Indonesia adopts semi-washing method. Brazil has also begun to use semi-washing in recent years, which is the only one in the world that has both sun exposure. The country of production of these three treatments: water washing and semi-washing.

That is, the coffee fruit is immediately picked when it turns red, the hard peel is removed by machine, the sticky berries are exposed, and then thrown into the pool to ferment. In about a day or two, the bacteria will eat most of the pulp attached to the seeds. The whole fermentation process needs to be monitored by the old master, if it goes too far, it will destroy the quality of coffee beans. After the berries are removed by fermentation, rinse the residual pulp attached to the seeds with clean water. At this time, the seed has been taken out, and then the drying process, it is best to lay the ground for the sun to dry, the flavor is better, but if it rains, it can also be dried by machine, but the temperature should be controlled. Dry and then polish
