Characteristics of grinding degree of Ethiopian coffee introduction of high-quality coffee beans

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 great news for Ethiopia, where coffee grading and quality control systems are 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.

Even the official research unit of Ethiopia does not know how many Arabica subspecies there are in Ethiopia. The coffee cooperatives in this mountain are certainly different from those planted in another mountain, and even small farmers in the same region grow different varieties of coffee. It has been estimated that there are at least 2000 varieties of Ethiopian coffee and even more than 4500 kinds of coffee. Compared with the fat posture of Bourbon 'SL28', the main variety to the south of Kenya, or Tibica in Central and South America and Asia, Ethiopian beans look a little malnourished. But "beans" can not be seen, Ethiopian coffee has the most citrus aroma in the world, whether it is instant coffee or freshly ground coffee, you can smell the aroma of orange or lemon when you extract it. The nose is characterized by strong floral, fruity, sour and sweet aromas, but the alcohol is slightly thicker or less dense. The biggest disadvantage is that it is easy to bake unevenly, especially sun-dried beans. Even the best Grade3 Harald sun-dried beans often show uneven color, which is the biggest defect of Ethiopian beans, but the good thing is that it does not affect its good flavor. For coffee fans, you don't have to worry about what the beans look like, it's the most important thing. The stability of Ethiopian water-washed beans is much better than that of sun-dried beans, whose flavor fluctuates greatly every year, so be sure to test it several times before buying in large quantities. If you buy good sun-dried beans, their flavor is much deeper than water-washed beans, but if you buy improperly handled sun-dried beans, it will certainly make people speechless, which is the wish of many coffee fans.
