Introduction to the planting Environment of Flavor and taste in the Coffee Manor of Arusha, Tanzania

The topography of Tanzania is high in the northwest and low in the southeast, showing a ladder shape. The eastern coast is a lowland, the western inland plateau accounts for more than half of the total inland area, and the East African Rift Valley runs from east to west from Lake Malawi to the north and south. The Kibo peak of Mount Kilimanjaro in the northeast is 5895 meters above sea level, which is the highest peak in Africa. [6]

Climate

The eastern coastal areas and inland lowlands of Tanzania have a savanna climate, while the western inland plateau has a tropical mountain climate, with an average temperature of 21-25 ℃ in most areas. More than 20 islands in Zanzibar have a tropical maritime climate, hot and humid all the year round, with an annual average temperature of 26 ℃. [6]

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 reaches 500-1000 mm.

Hydrology

The main rivers in Tanzania are the Rufidi River (1400 km long), the Pangani River, the Rufu River, the Wami River and so on. There are many lakes, including Lake Victoria, Lake Tanganyika and Lake Malawi. [7]

Tanzania is rich in mineral resources. By 2014, the major minerals identified include gold, diamond, iron, nickel, phosphate, coal and various gemstones, ranking fifth in Africa in total. Tanzania also has huge natural gas reserves. According to official data released by Tanzania, Tanzania has proven natural gas reserves of 44 trillion cubic feet, and the total reserves are expected to reach at least 200 trillion cubic feet.

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 screen with fixed size holes, the larger the number of the screen is, the larger the particles of coffee raw beans are. The grades of flat beans distinguished 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. Coffee graded specifically for round beans is one of the main cash crops in Tanzania. Among the export crops of Tanzania, it ranks fourth after cotton, tobacco and cashew nuts, mainly sold to Italy, Japan and the United States. Coffee exports play an important role in the Tanzanian national economy. 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 harvesting the amount of coffee fruit, and small farm women use their hand-made sacks to bring coffee fruit to the farm to calculate the money.
