What's the difference between sun-cured and half-washed Mantenin coffee beans?

The shelling process is to grind off the bean shell with a shell planer and then dry it until the moisture content reaches about 12% to 15%. The coffee beans are then sent to machine selection to remove various impurities and then sorted by particle size.

The general "Mantenin" coffee has the unique fragrance of herbs and trees, and the particle size is relatively irregular; the "Golden Mantenin" coffee of Indonesia's Pwangni Coffee Company or the "Jinding Mantenin" coffee of the Japanese company are mellow and bright, and the sweet aroma of caramel is more intense. the fruit acidity is also bright and elegant, and there is almost no herbal, earthy and woody taste of Mantenin. Mantenin coffee is suitable for medium-and low-grade roasting, which can reduce miscellaneous flavor, while gold manning has a wider roasting range.

In 1877, a large-scale disaster hit the Indonesian islands, coffee rust destroyed almost all the coffee trees, people had to give up Arabica, which had been in operation for many years, and introduced the disease-resistant Robusta coffee tree from Africa. Indonesia today is a big coffee producer. Coffee is mainly produced in Java, Sumatra and Sulawi, with Robusta accounting for 90% of the total production. Sumatra Manning is a rare Arabica species. These trees are planted on hillsides between 750m and 1500 meters above sea level, mysterious and unique Sumatra, giving Mantenin coffee, rich aroma, rich taste, strong flavor. Make uniquely, with a hint of chocolate and syrup

The processing process and Sumatran characteristics. I describe these treatments in such detail because it is not clear how the soil and atmosphere and the unusual treatment techniques and the three-stage drying each affect the formation of the characteristics of Lindong and Manning coffee. Only one thing is certain. These treatments occasionally produce excellent coffee and are extremely unstable. Only by the merciless selection in the Medan port exporter's warehouse can we ensure that the deep texture of Lintong Lin Dong and Mandheling Mantenin and the unique and low-key rich taste can emerge from the interference of other smells.

Manning needs layers of screening, which I think is absolutely necessary. The probability of defective beans is too high, coupled with the ugly appearance, sometimes good beans look like defective beans. Every time I pick Mantenin, I can pick out a handful of defective beans, look back in the defective beans, and feel that it is not defective beans, it looks like this. However, after baking, Mantenin is like a caterpillar breaking its cocoon into a butterfly. The ripe beans are very full and look quite pleasing to the eye.

Coffee beans have four layers of protection-pericarp, pectin, seed shell and silver skin. In the washing method, only the first two layers were removed, and the seed shell and silver coat were preserved and dried in the sun. On the other hand, the wet planing method cuts off the third and fourth layers of protection, that is, the falling body is sunbathed, which is why the raw Sumatran beans are turquoise. Although the wet planing method shortens the drying time, it also greatly increases the probability of being unmanned by molds, fungi and yeasts.
