Description of Coffee Flavor in Chilmel Manor, Rwanda; introduction to the characteristics of grinding degree and price

The watershed between the Congo basin and the Nile basin runs through Rwanda from north to south, with about 80 per cent of the country draining from the Nile and about 20 per cent from the Ruzi River and Lake Tanganyika. The longest river in the country is the Niabalongo River (Nyabarongo River) in the southwest, which turns north, east and southeast into the Ruwuwu River and forms the Kagera River, which flows due north along the eastern border of Tanzania. Both the Niabarongo River and the Cagella River will eventually flow into Lake Victoria. There are many lakes in Rwanda, of which Lake Kivu is the largest. The lake is located at the bottom of the Aberdeen Rift Valley and extends along the western border of Rwanda. With a maximum depth of 480 meters, it is one of the 20 deepest lakes in the world. Several other larger lakes include Lake Burera, Lake Ruhondo, Lake Muhazi, Lake Rweru and Lake Ihema, of which Aishma is the largest in a series of lakes in the eastern plain of Akagera National Park.

Rwanda has been growing coffee since colonial times. Although the crops are mainly coffee, the quality of coffee produced in Rwanda is not outstanding, and its status in the coffee world is low, and few people pay attention to it. Most of the coffee varieties grown in Rwanda are bourbon. Rwanda, known as the "country of a thousand hills", has a high-altitude mountain environment, fertile volcanic soil and abundant precipitation, and has a climate conducive to the growth of coffee trees. The advantages of varieties and excellent natural conditions should have produced high-quality coffee, but why the quality of its coffee performance is not satisfactory? The reason lies in the later stage of processing. Improper handling will reduce the quality of coffee and sacrifice a lot of good flavor in vain. Harvesting, planting, treatment, grading, transportation and other links will directly affect the quality of raw coffee beans, in which the lack of control in a certain link will become a stumbling block to good coffee.

The coffee fruit needs to be transported to the processing plant as soon as possible after picking, but due to the lack of domestic facilities, it is unable to deal with the fruit at the first time. The fruits are piled up after being picked, which will continue to develop and accelerate mildew and decay due to lack of ventilation. Rotten fruits will affect the quality of coffee and show defective flavor.

In recent years, Rwanda has made great progress in the production and processing of coffee. First of all, coffee fruits are picked manually; coffee production cooperatives are set up all over the country to provide technical guidance to coffee farmers; coffee farmers send them to coffee processing stations for cleaning and screening as soon as possible after picking, and select mature and high-quality coffee fruits for processing.

Most of the coffee in Rwanda is washed. The water washing method will first wash and flotation the ripe coffee fruit, then remove the exocarp, pulp and part of the pectin layer, then send the coffee into the fermentation tank, remove the remaining pectin layer and then send it to the drying ground for drying treatment, so that the water content reaches about 13%. The coffee in the picture above is dried on an African shed to avoid the smell of dirt. It is more ventilated and mildew can be avoided. In the process of drying, coffee farmers will also turn the beans regularly to make the drying more even. at the same time, they will pick out the beans of poor quality and discard them.
