Sun treatment (natural process) can be said to be the earliest way to treat coffee beans.

After picking the coffee fruits from the fruitful coffee trees, spread them all flat on the ground and wait for the sun to dry the skin and flesh of the coffee fruits.

Coffee cherry is composed of exocarp, pulp, pectin layer, endocarp, silver peel and coffee germ from outside to inside, so coffee beans will be treated by various methods before they are turned into raw beans for export.

The sun drying method is to directly expose the coffee fruit to the sun. When the moisture content of the coffee bean is lower than a certain degree, the exocarp is removed by machine to the endocarp once. The advantage is that the flavor is rich, but the disadvantage is that it will produce more defective beans and need more space.

The hard work of the sun will not be wasted, good quality sun beans, the sugar of the whole ripe fruit is condensed into the beans bit by bit by sunlight, the fruit aroma is very rich, and the taste is mellow, the sweetness is high, and the acidity is not as sharp as washed beans; the special fermented taste of sun fruit makes many people fall in love with it after drinking it several times.

In the former street sun Yega [berry orchard], for example, the sun treatment gave the bean a strong aroma of fermented berries, tasted very sweet, but more like a cup of fruit wine than coffee.
