A brief introduction to the description of flavor and aroma characteristics of Sidamo coffee beans with lively and sour taste

The coffee beans after harvest must enter the treatment program immediately, otherwise they will begin to ferment, making the coffee beans have a bad smell. There are two methods of treatment: "solarization" and "washing", which will cause different flavors. Sun-cured beans have a complete natural mellow flavor, gentle aroma and more gum; washing rules have a good mellow taste, high aroma and lively sour taste

Yega Xuefei is a small town, 700-2100 meters above sea level, synonymous with Ethiopian boutique coffee. It has been a wetland since ancient times. The ancient saying "Yirga" means "settle down" and "Cheffe" means "wetland". The mode of production and flavor of coffee here are so outstanding that Ethiopian coffee farmers compete to take pride in the flavor of their coffee, making it the most famous coffee producing area in Africa.

Located in the most advantaged natural conditions, Ethiopia produces unique high-quality coffee every year. Ethiopia's coffee growing cycle brings the joy of harvest to the country every year. Beautiful white coffee flowers will bloom and bear fruit every year from March to April. Only the reddest and ripe fruits are selected as coffee ingredients between September and about December. The export of new coffee starts in November or December every year.

Coffee is Ethiopia's most important export cash crop and the main source of Ethiopia's foreign exchange earnings. Ethiopia's coffee exports account for about 3% of the world market, making it the eighth largest coffee exporter in the world. Coffee exports increased steadily from 58000 tons in 1990 to 110000 tons in 1995-1996 and remained at this level in the following years. The export volume exceeded 110000 tons from 2001 to 2002 and reached 127000 tons from 2002 to 2003. As the price of coffee on the international market has been declining for a decade, Ethiopia's foreign exchange earnings have been seriously affected. Before the sharp drop in coffee prices, coffee exports accounted for more than half of Ethiopia's foreign exchange earnings, but now they account for only about 35 per cent. But according to the International Coffee Organization, coffee prices rebounded in 2002, rising from 41 cents per pound in September 2001 to 52 cents per pound in 2002 and 59.7 cents per pound in 2003. The average price in March 2004 was 60.8 cents per pound, an increase of 50% over September 2001. This is excellent news for Ethiopia.

Due to different planting methods, coffee can be divided into forest-semi-forest coffee (Forest or semi-forest coffee), courtyard coffee (Garden coffee) and plantation coffee (Plantation coffee), accounting for 35% of exports. Good quality washed coffee is processed with freshly picked fully ripe fruit, picked carefully and closely monitored by professionals. The picked clean coffee beans are pulped on the day of picking, then fermented, washed, dried and peeled. The humidity of processed coffee beans is maintained at about 12% in Ethiopia. The grading and quality control system of coffee is divided into three levels: producer, regional and national. All coffee is inspected by local inspection agencies before leaving the country of origin, and then re-tested at the coffee inspection and grading centers in Addis and Diredawa to determine its quality grade. Coffee is graded before auction and sale and is important for all groups involved in production, acquisition, export and consumption. Before export, coffee must also be sent to a national quality control agency for inspection to confirm that the origin and color meet the export standards. in order to ensure the reputation of Ethiopian coffee, Ethiopia's coffee grading and quality control system mainly has two indicators: visual inspection and cup evaluation, inspection items include the color, cleanliness, origin, taste and characteristics of coffee beans. The export rating is marked by simple numbers, with the best washed coffee at level 5 and the best sun-cured coffee at level 4. After grading, mark the place of origin and then export. Exports are usually paid by letter of credit, which can not only reduce the risk of foreign exchange collection for exporters, but also give quality assurance to importers.

1. When picking beans, only fully ripe crimson coffee cherries are picked. Before exposure, the beans will be screened for defects in the processing plant to make the beans look more average in size and maturity.

two。 Next, use tall wooden frames or whole scaffolding for the sun to avoid the risk of beans smelling on the ground. In the process of exposure, take good care of the beans so that the coffee beans can be evenly exposed to water; every three to five days, coffee workers will manually screen out defective and moldy beans. Therefore, by the end of the exposure, before the beans enter the market to remove the peel and flesh, a bright crimson coffee cherry is already a grade with few defects.
