The method of water treatment originated in Africa. Because the water washing method consumes too much water and causes serious pollution, the semi-washing method is produced, which means that the coffee fruit first removes the defective floating fruit through the sink, then removes part of the colloid layer, and then washes it for an hour, due to the short immersion fermentation time, there is still pectin left on the bean shell, and then spread the coffee beans in the sun field to dry at this time. Semi-washed coffee not only has the consistency and sweetness of sun beans, but also has the cleanliness and softness of washed beans, which makes the coffee taste better.
