Introduction to Qianjie-Ethiopia grading system

Ethiopia is known as the "birthplace of coffee". As a hot coffee exporter, Ethiopia redefines the classification of raw coffee beans in this country in order to uniformly distinguish many producing areas according to certain factors and ensure a unified standard for import and export.

Ethiopian coffee grading

G1: 0-3 defective beans per 300 grams of raw beans G2: 4-12 defective beans per 300 grams G3: 13-25 defective beans per 300 grams

G4: represents 26-45 defective beans per 300 grams G5: represents more than 45 defective beans per 300 grams

The specific grading and scoring criteria of ECX are as follows

Score definition of washing treatment method

Tips:

According to the physical characteristics and the basic quality of the cup test, the sun / water washing treatment method was scored as 9 grades of G1-G9, and the G1-G3 was tested again according to the SCAA standard to evaluate its flavor properties in more detail. Among them, G1 and G2 of ≥ 85 were rated as Q1, (Q1 and Q2 were classified as Specialty Grade export, Specialty Grade meant fewer defects and high flavor quality;), G2 G3 was rated as Q2 for the score of 80-85, and G3 for all G1meme G2 G3 with scores less than 80; (meaning that it could not reach the grade of fine goods, but higher than the grade of domestic consumption).
