Introduction to the flavor description method of coffee manor in Arusha, Tanzania

In 1886, Tanganyika Inland was placed under the German sphere of influence. In November 1917, British forces occupied the whole territory of Tanganyika. In 1920, Tanganyika became a British "mandated territory". In 1946, the United Nations General Assembly adopted a resolution to change it into a British "trust land." on May 1, 1961, Tanzania achieved internal autonomy, declared independence on December 9 of the same year, and established the Republic of Tanganyika a year later.

Zanzibar became a British "protectorate" in 1890, gained autonomy on June 24, 1963, declared independence on December 10 of the same year, and became a constitutional monarchy ruled by the Sultan.

On January 12, 1964, the Sang people overthrew the sultan and founded the Zanzibar people's Republic. Tanganyika and Zanzibar formed a United Republic on April 26, 1964, and changed its name to the United Republic of Tanzania on October 29 of the same year. Julius Kambarage Nyerere was the founding president and was re-elected twice until he resigned voluntarily in 1985. Mwinyi was elected the fourth president of the United Republic on October 27 of the same year and was re-elected in 1990.

In December 1992, the Zanzibar government joined the Organization of the Islamic Conference (OIC) without authorization, which was strongly opposed by the coalition government and was forced to withdraw in 1993.

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 raw coffee beans through a sieve with fixed size holes, the larger the number of the sieve is, the larger the particles of raw coffee beans are. The flat beans classified by size are mainly AA+, AA, AB. In addition, PB (peaBerry), which is more produced in Kenya and Tanzania, also has a set of sieve size standards dedicated to grading the size of round beans.

Tanzania is also often compared with its nearest neighbor Kenya. It is said that the earliest Arabica coffee in Tanzania was introduced by Christians from Kenya and is similar to Kenya in flavor characteristics. With grapefruit aromas and soft and bright acidity. However, because the economic conditions of Tanzania are worse than those of Kenya, the production conditions are poor. Tanzania's quality control is not strict enough, destroying the quality of coffee in many processing links, which can not compete with Kenya, which is famous for its high quality. Although it is similar to the Kenyan flavor, Tanzania as a whole is smoother and softer and belongs to the balanced type. With moderately low acidity and sweetness, dark chocolate finish, moderate mellow thickness. Compared with Kenya, which has a prominent personality, Tanzania is less hierarchical and does not give a very prominent feature after drinking, which makes people less impressive. But on the contrary, its soft and round characteristics are also more pleasing, which is easy to be accepted by people who are new to coffee.

The picture above shows washed beans from Kilimanjaro, Tanzania, planted above 1800 meters above sea level. Cooked beans are moderately baked. Raw beans show yellowish green, beans particles are small and round, the particle size is more uniform. When the hand flashes, Tanzania's performance is slightly lower than that of Kenya, and it is prone to the smell of cucumbers and green beans. The acidity will be concentrated in the front, and after moderate acidity and sweetness, it will show chocolate and woody aromas. As for the cooking method of this bean, I recommend siphon. The siphon pot will enhance the sweetness and make the flavor more concentrated, and the increase of alcohol thickness will make up for the thinness of the flavor. On the whole, the performance of the siphon pot is better than that of hand flushing.
