In some countries with frequent rain and high humidity, although the process is relatively tedious, it is the most widely used treatment method at present. Because of the use of a lot of water washing method, the flavor and taste are quite clean. Coffee bean washing method is also mostly with bright acidity and flower and fruit aroma.

The harvested coffee cherries are peeled and pulped, and the remaining seeds and a layer of residual mucous membrane are thrown into the sink and fermented with water. The whole fermentation time is only about 24-30 hours.

Compared with the sun-drying coffee bean washing method, the quality of coffee bean washing method is obviously better. In the process of water washing treatment, the defective beans floating on the water surface can be easily removed, and the flavor is not easy to appear.

Also because the fermentation time is short and the beans are naked and washed in the sink, the coffee bean washing method will show a clean and flawless taste. The key point is that the coffee fruit is fermented after peeling, and the pectin is washed off with water after fermentation. One of the treatment methods used is that after the coffee fruit is picked, the immature fruit and miscellaneous leaves are removed, the outer skin of the fruit is removed, the beans are picked out, and then the beans are washed and soaked, so that the beans begin to ferment, allowing microorganisms and enzymes to decompose the components of the beans and produce sour flavors. The water washing method can also be a dry fermentation method without soaking, and then wash off the pectin with water after fermentation. After fermentation, the beans are then insolated or dried to prevent coffee beans from getting moldy. The correct method of washing coffee beans usually tastes mild, and depending on the environment and fermentation, it may also have a wine flavor.
