Introduction to the grading Standard of Fine African beans and Indonesian Coffee Raw beans

Indonesian mantenin coffee beans

Asia's best-known coffee producers are the Malay islands of Sumatra, Java and Kalimantan. Sumatra mantinin coffee from Sumatra, Indonesia is the most famous of these, and it has two famous names, Sumatra mantinin DP First Class and Sumatra Mantinin Collection. Sumatra Mantenin DP has a long aftertaste and a wild fragrance, which is characteristic of the earthy taste of virgin forests. In fact, Mantenin's mellowness was a very masculine feeling. A good quality first class mantelin coffee has a light acidity, like the slight acidity of flowers and fruits. In addition to Indonesian coffee's rich flavor, there is also a bitter sweet flavor that is popular with strong roast coffee drinkers; the collection Sumatra mantnin coffee is called "collection" because it is stored in the cellar for three years before export. But reserve coffee is not old coffee, but a slightly pale coffee that has been specially treated. This coffee is stronger, the acidity will be reduced, but the alcohol will increase, and the aftertaste will be longer. It will also have a strong spicy taste, sometimes bitter, sometimes walnut, and sometimes chocolate. Before Blue Mountain coffee was discovered, mantnin was considered the best coffee. It is interesting to note that while Indonesia produces some of the finest coffee in the world, Indonesians prefer Turkish-style coffee sellers often label Lintong Lindong and Mandheling Mandheling as dry processed. In fact, the pulp is often separated from the coffee seeds by a variety of mixing modes, more commonly a backyard wet treatment. Clever farmers put freshly picked coffee cherries into a crude peeling machine assembled from scrap metal, wood and bicycle parts. The peeled, sticky beans are then fermented overnight in plastic woven bags. The next morning, wash off the soft, fermented pulp and stickiness by hand. The silver-coated coffee is pre-dried on a sheet in the front yard and sent to a middleman's warehouse where the silver is removed and further dried. Finally, the coffee is trucked to Medan Port (capital of Sumatra) for the third and final drying. It has also been reported that in other Mandheling regions, after removal of the pericarp, the mucilage is allowed to dry and adhere to the beans, as in Brazil with semi-washing. After that, the dried slime and silver skin are removed by machine. The final drying is the same two-stage drying process, first at the middleman's warehouse and then at the exporter's warehouse in Medan.

Process with Sumatra characteristics. I describe these processes in such detail because it is not clear to what extent soil and atmosphere and unusual treatment techniques and three-stage drying each affect the formation of the characteristics of Linton and Mantenin coffee. Only one thing is certain. These treatments occasionally produce excellent coffee but are also extremely unstable. Only relentless picking in the export warehouse of Medan Port can guarantee the depth of texture and unique, understated richness of Lintong and Mandheling, emerging from the interference of other odors.
