Introduction to the method of regional flavor description and taste treatment of coffee beans in Tanzania

In early 2010, there was a new movement towards political reconciliation on Sang Island, with the Revolutionary Party and RUF agreeing on the formation of a Unity Government on Sang Island. In July of the same year, Sang referendum passed a resolution to establish a new constitution of national unity government system. In November, Sang general election was successfully held. Sang Island established a national unity government. Sang President, Second Vice President and 11 ministers came from Revolutionary Party. Sang First Vice President and 8 ministers came from RUF Tanzania. Tanzania covers an area of 945087 square kilometers, of which Zanzibar is 2657 square kilometers. It consists of the mainland, Zanzibar Island and more than 20 small islands. Located in eastern Africa, south of the equator, the continent borders the Indian Ocean to the east, Zambia, Malawi and Mozambique to the south, Rwanda, Burundi and Congo (DRC) to the west, Kenya and Uganda to the north. The rainfall patterns of 840 km long continental coastline are divided into bimodal distribution and unimodal distribution. The areas with bi-modal rainfall distribution include the provinces around Lake Victoria Basin, the northeast highlands, the coast and the northeast inland. The bi-modal rainfall distribution area is characterized by two long and short rainy seasons. The short rainy season occurs from September to December, and the total rainfall can reach 200-500 mm. The long rainy season occurs from March to May, and the rainfall can reach 300-600 mm. The areas other than the double pattern rainfall area belong to the single pattern rainfall area. The rainfall time is from November to April, and the rainfall reaches 500-1000 mm.

Tanzanian coffee is often washed, and coffee farmers will send the coffee fruit to the nearest processing plant for processing after picking. The treatment steps of the washing treatment method are as follows: firstly, impurities doped in coffee fruits are screened and removed; then coffee pulp and exocarp are removed; the coffee fruit is sent into a fermentation tank, and pectin layers adhered to the endocarp are removed through fermentation; and drying treatment is carried out after cleaning. Tanzanian coffee is graded in the same way as Kenyan coffee, according to bean size. During screening, green coffee beans are allowed to pass through a sieve with holes of fixed size. The larger the number of sieve, the larger the particles of green coffee beans. The flat beans classified by size mainly include AA+, AA and AB. In addition, there is a set of sieve size standards for PB (peaBerry), which produces more round beans in Kenya and Tanzania, to classify the size of round beans.

Tanzania is also often compared to its neighbour kenya. It is said that Tanzania's earliest Arabica coffee was introduced from Kenya by Christians and is similar to Kenya in flavor characteristics. Grapefruit aromas and soft, bright acidity. However, since Tanzania's economic conditions are worse than Kenya's, production conditions are poorer. Tanzania is also not strict enough about quality control, destroying the quality of coffee in many processing steps, and Kenya, which is known for its high quality, cannot compete. Although it is close to Kenya's flavor, Tanzania's overall taste is smoother and softer, belonging to the balanced type. Moderately low acidity and sweetness, dark chocolate finish, moderate body. Compared with Kenya, which has outstanding personality, Tanzania is not so rich in hierarchy. After drinking, it will not give feedback on its outstanding characteristics, which makes people not too impressed with it. But on the contrary, its soft and round characteristics are also more pleasing, easy for people who have just come into contact with coffee to accept.
