Description of coffee flavor in Kilimanjaro, Tanzania introduction to the treatment of grinding degree and baking degree

Tanzania is an East African country south of the equator, bordered by Uganda and Kenya to the north and the Republic of the Congo, Rwanda and Burundi to the west. It is hot and humid all the year round, with an average temperature of 21-25 ℃ in most areas. Precipitation is divided into long and short rainy seasons, and the annual precipitation is abundant. The economy is dominated by agriculture, and coffee is one of the main cash crops in Tanzania. Arabica coffee and Robusta coffee are grown in Tanzania.

Mount Mount Kilimanjaro, located in northeastern Tanzania, is the highest mountain in Africa at 5895 meters above sea level. The ultra-high altitude makes the top of the mountain snow all the year round, while Tanzania's main coffee producing area is located at the foot of Mount Kilimanjaro. The area is rich in volcanic soil, which brings an adequate supply of nutrients for the growth of coffee trees. Coffee trees are generally planted at high elevations above 1150 meters, which is one of the prerequisites for Arabica to develop a high-quality flavor.

Tanzanian coffee is mostly washed. After picking, coffee farmers will send the coffee fruit to the nearest processing plant for processing. The treatment step of the water washing method is to screen and remove the impurities in the coffee fruit, then remove the coffee pulp and exocarp, and send it into the fermentation tank to remove the pectin layer on the inner pericarp by fermentation. clean and then dry. Coffee in Tanzania is graded in the same way as in Kenya, both according to the size of coffee beans. When screening, let the raw coffee beans pass through the screen with fixed size holes. The larger the number of the screen is, the larger the particles of the raw coffee beans are. The flat beans classified by size are mainly AA+, AA and AB. In addition, PB (peaBerry), which is widely produced in Kenya and Tanzania, also has a set of sieve size standards, which specifically classify the size of round beans.

Coffee is one of the main cash crops in Tanzania, ranking fourth after cotton, tobacco and cashew nuts, mainly sold to Italy, Japan and the United States. Coffee exports play an important role in the national economy of Tanzania. Tanzania's main coffee-producing area, located at the foot of Mount Kilimanjaro, is rich in volcanic soil. Some coffee trees are more than 100 years old. Coffee was first introduced and planted by Christians from Kenya. Coffee trees must be carefully cared for, weeded, fertilized, and old branches must be cut off so that new branches can grow to maintain the quality of coffee beans. The processing plant is located in a nearby town at the foot of the mountain, making it easy to handle coffee beans nearby. Many of the farm owners' families have lived here for generations of immigrants, including Indians, Scandinavians, British, and, of course, locals, but most of them are small farms. however, the managers of farms and processing farms are mostly local people. Labor in Tanzania is cheap, so much of the work of pruning and maintaining coffee plantations in Tanzania depends on manual processing rather than machines. During the coffee growing season, the job of coffee workers is to manually check to remove the leaves of some sick or growing insects. Coffee processing in Tanzania is highly dependent on labor, but it also brings jobs to locals and increases household income. Workers earn their wages by picking the number of coffee fruits, and women on small farms use their hand-made sacks to bring coffee fruits to the farm to calculate the money.
