Last Updated: 2026/04/04, 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.

Solarization is a traditional method of primary processing of coffee beans, and ancient coffee growing countries such as Ethiopia and Yemen still use solarization almost exclusively for raw beans.

Sun-drying begins by spreading tank-identified beans, ripe or semi-ripe, on a drying ground. The exact time depends on local climatic conditions, and generally takes two weeks to four weeks. When the moisture content of the coffee beans is reduced to 12%, then use a husker to grind off the dried pulp and silver skin.

Sunlight treatment is very demanding on the climate. If it rains during the sun, it will make the beans regain moisture and mold.

Sun-dried beans are yellow when raw and brown in the center when baked, rather than white when washed.

Sun-baked beans have a relatively better sweetness and body, and less sourness, but the quality is less stable and will have greater fluctuations.

Solarization is widely used not only in Ethiopia and Yemen, but also in Africa and Indonesia, where Rochester coffee is grown because of its low cost.
