Introduction to the characteristics of high-quality coffee beans with flavor and taste in Tanzania coffee producing areas

Tanzania covers an area of 945087 square kilometers, of which Zanzibar is 2657 square kilometers. It consists of the mainland, Zanzibar and more than 20 small islands. Located in eastern Africa and south of the equator, the continent is bounded by the Indian Ocean to the east, Zambia, Malawi and Mozambique to the south, Rwanda, Burundi and the Democratic Republic of the Congo to the west, and Kenya and Uganda to the north. The coastline of the mainland is 840 km long

The types of rainfall can be divided into bimodal distribution and unimodal distribution. The areas with double bee rainfall include the provinces around the Lake Victoria basin, the northeast highlands, the coastal and inland northeastern. The bimodal rainfall area is characterized by two rainy seasons. The short rainy season occurs from September to December. The total rainfall can reach 200-500 mm. The long rainy season occurs from March to May, and the rainfall reaches 300-600 mm. The areas outside the double bee distribution rainfall area belong to the single bee distribution rainfall area. The rainfall time is from November to April, and the rainfall is up to 500-1000 mm.

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 agreeable, which is easy to be accepted by people who are new to coffee.
