Washing method: the use of washing and fermentation methods to remove the peel pulp and mucosa. This method is also known as "Fully washed". Washing is the most common method of processing Arabica coffee beans in most of the world's coffee-producing countries. In some areas, advanced high-pressure washers are used to clean the skin, pulp and mucosa of coffee beans, so fermentation is no longer required. This method of treating coffee beans with a high-pressure washing machine is called Pulped Natural.

Semi-washing method: The specific method is to dry the coffee fruit with sunlight first, and then rinse off the outer skin and pulp with water. Unlike the washing method, the coffee fruit is not put into the sink for fermentation. Semi-washed coffee beans are always sticky, but their acidity, sweetness and aroma are quite good.
