Coffee bean treatment-half-sun method

In order to improve the quality of coffee in Brazil, the Brazilian government has invented half-sun method and vigorously promoted it. At present, almost all high-quality coffee beans in Brazil use half-sun method to treat raw beans. It can be said that half-sun method has successfully improved the overall quality of Brazilian coffee.

The pre-treatment method of the half-sun method is almost the same as the water washing method, first put the coffee fruit into a large water tank, remove the floating fruit, and then put the sunken fruit into the pulp sieving machine to remove the pulp. Through the above steps, not only the immature fruit can be better removed, but more importantly, when the coffee beans are dried in the sun, they are no longer with pulp, but only wrapped in a layer of pectin, which is more helpful to control the subsequent fermentation process. After removing the pulp, the fermentation process is somewhat similar to the drying method. The beans are moved to the bean drying farm to dry, which can reach a certain degree of drying in about 3 days, and then further dried with a dryer until the water content of the beans reaches 10.5% to 12%. The final polishing process will be carried out before the beans are bagged and exported.

Because the half-sun method has certain requirements for climate and technology, it can only be widely used in Brazil. Through half-sun treatment, it not only retains the unique sweet taste of the sun method, but also avoids the mildew taste of the sun method, shaping the unique flavor of Brazilian coffee.
