The sun method of raw coffee beans introduces the ratio of coffee powder to water.
Tanning is a traditional method for the initial processing of coffee beans, and at present, almost all coffee-growing countries such as Ethiopia and Yemen still use solarization to treat raw beans.
Sun treatment will first identify sunken beans in the sink, that is, ripe or half-ripe beans are spread in the drying farm for natural drying. The specific time depends on the local climatic conditions, which usually takes two to four weeks. When the moisture of the coffee bean is reduced to 12%, then use a sheller to grind off the hard pulp and silver skin.
The sun treatment has a very high requirement on the climate, and if you encounter a rainy day in the sun, it will make the beans moist and moldy.
When drying raw beans in the sun, the color is yellow, and the center will be brown after baking, rather than the white of washed beans.
Sun beans have relatively better sweetness and mellow thickness, while less sour taste, but the quality is more unstable, there will be greater fluctuations.
Due to the low cost of sun treatment, it is widely used not only in Ethiopia and Yemen, but also in Robusta coffee beans grown in Africa and Indonesia.
