A brief introduction to the treatment method of grinding degree and baking degree of fine coffee beans in Berman Manor, Kenya.

There are many producing areas in Kenya that strive to preserve the native forest ecosystem, protect the natural gene pool, support the reproduction of wild coffee varieties and breed a variety of coffee trees. A bourbon line screened and cultivated by French and British missionaries and researchers in Kenya at the beginning of the 20th century. Over the past hundred years, it has adapted to the high concentration of phosphate soil in Kenya, giving birth to the special sour and fragrant spirit of Kenyan beans, which is different from bourbon beans in Central and South America. This Kenyan native species was created by Scott Laboratories in 1930, known as SL for short. Agronomists wanted to find a kind of bourbon with high yield and resistance to diseases and insect pests, and obtained SL28 through experiments. SL28 is a genetic variant with a mixed pedigree of French missionaries, mochas and Yementibica. The original goal of breeding SL28 was to mass-produce coffee beans with high quality and resistance to diseases and insect pests. Although the yield of SL28 was not as high as expected the copper leaf color and broad bean-shaped beans have great sweetness balance and complex flavor as well as significant citrus and black plum characteristics. This important variety leads us to the unique Kenyan style: strong acidity, rich taste and beautiful balance. Kenya AA is one of them.

AA is a class name for the currency of raw coffee beans. The grade of raw coffee beans is generally AA,A,B,C, which mainly refers to the size of coffee beans. AA refers to coffee beans with larger particles, and coffee beans with particles of more than 17 mesh (17 mesh = 6.75MM).

SL28 is a delicious variety, suitable for growing in mid-and high-altitude areas where leaf rust is not serious. It can produce 1.8 tons of raw beans per hectare and drink the charming sour plum flavor to reflect the national treasure of Kenya.

It entered Kenya in the 19th century, when Ethiopian coffee drinks were imported into Kenya through southern Yemen. But it was not until the early 20th century that the bourbon was introduced by the St. Austen Mission (St.AustinMission).

Kenyan coffee is mostly grown at an altitude of 1500m, 2100m, and is harvested twice a year. To ensure that only ripe berries are picked, people must tour the forest about seven times. Kenyan coffee is grown by small farmers. After they harvest the coffee, they first send the fresh coffee beans to the cooperative cleaning station. The washing station sends the dried coffee to the cooperative in the form of "parchment coffee beans" (that is, coffee beans covered with endocarp) to the cooperative ("parchment coffee beans" is the last state of coffee beans before peeling). All the coffee is collected together, and the growers charge the average price according to their actual quality. This trading method generally works well and is fair to both growers and consumers.

Kenya is bordered to the north by Ethiopia, the origin of Arabica coffee trees, but it was not until the beginning of the 20th century that coffee cultivation began. In the 19th century, missionaries introduced Arabica trees from the leaves, but did not plant them in large quantities. It was not until 1893 that coffee was cultivated on a large scale after the introduction of Brazil's ancient bourbon seeds. That is to say, Kenyan coffee was of Brazilian origin. Due to the differences in water, climate and handling, the taste of Kenyan beans is very different from that of Brazilian beans. Brazilian coffee is planted at a low altitude, with soft texture and no obvious sour taste. In contrast, Kenyan coffee trees are mainly concentrated on the slopes near Mount Kenya, about 4 to 6500 feet above sea level, which is suitable for coffee beans to develop their flavor, because the mountain temperature is lower and the growth is slower, and the aromatic components of coffee beans are fully developed. the acidity of the fruit is more obvious and the texture is harder. In addition, Kenya was an early British colony, and the British had established a set of perfect cultivation and quality control system. After Kenya became independent, the coffee industry was built on its existing foundation.

There are two types of coffee farms in Kenya. One is a large plantation that covers an area of more than five acres, but the average elevation is low. In the case of Kenyan coffee, the coffee beans of the large farms are of medium quality. The best Kenyan beans come from small farms, most of which are located in the foothills or volcanic slopes above 5,000 to 6,000 feet. Each small farmer has a capacity of only 20 to 70 bags per season and cannot afford to invest in expensive washing plants, but small farmers are very United. Hundreds or thousands of households are gathered to set up a cooperative farm, which is funded by the government to build a washing treatment plant, and the coffee fruits picked by small farmers are sent to the cooperative farm for unified processing. First remove the half-ripe or rotten fruit, then peel, ferment, decompose the flesh, remove the coffee beans, then dry and polish, the whole process is supervised by the official Coffee Administration, which ensures the quality of Kenyan coffee. The washing technology and high standard quality control of Kenyan beans have always been an example of bean producing countries.

Accounting for 55% of Kenya's total coffee production (40% of the number of estates) is run by numerous small operators. Seeing that coffee is absolutely profitable, these small operators continue to increase the need for agronomy and the development of high-quality coffee tree species, thus greatly promoting the development of coffee in Kenya.

To ensure that only ripe coffee fruits are picked, people must tour the forest about seven times. After they harvest the coffee, they first send the coffee beans to the cooperative cleaning station, where the sun-dried coffee is sent to the cooperative in the form of "parchment coffee beans" (that is, coffee beans covered with endocarp) ("parchment coffee" is the last state of coffee beans before peeling).

The Kenyan government takes the coffee industry very seriously, where it is illegal to cut down or destroy coffee trees. Kenyan coffee buyers are world-class high-quality coffee buyers, and no other country can grow, produce and sell coffee on a continuous basis like Kenya. All coffee beans are first purchased by the Kenya Coffee Commission, where they are identified, graded, and then sold at weekly auctions, where they are no longer graded. The best coffee grade is bean berry coffee (PB), followed by AA++, AA+, AA, AB and so on. The fine coffee is shiny, delicious and slightly alcoholic. Kenyan Coffee has become more famous with the sensation of the Hollywood movie "out of Africa". Karen, the heroine played by Meryl Streep, is a writer and coffee planter. Many people probably remember Karen's yellow-and-white linen dress, the beautiful scenery and the magnificent sunset. What is even more unforgettable is Karen's dream of having a coffee plantation in Africa.

Kenya, located in East Africa, is one of the major coffee producing countries. More than 6 million people in the country are engaged in the coffee industry, mostly in the form of a combination of small farmers and cooperatives. Coffee trees in Kenya are mostly planted at 1400 m-2000 m above sea level, and the growing areas include Ruiri, Thika, Kirinyaga and Mt. Kenya West, Nyeri, Kiambu and Muranga. Mainly in the foothills of Mt.Kenya and Aberdare.
