Qianjie-introduction to Yunnan small Coffee

Although coffee has been grown in Yunnan for many years, it is still not mature enough. Its grading system is also relatively messy.

1. International commonly used grading standards:

According to the size of coffee beans, the round hole grading screen is used for classification. The international custom of small grains of coffee has a size of 10-20, and the number used represents the sieve aperture as the fraction with that number as the numerator and 64 as the denominator, in inches. For example: 14 refers to the raw coffee beans that can pass through a sieve with an aperture of more than 64 inches by 14thumb, and 19 refers to those that can be screened by a sieve with an aperture of more than 64 inches by 19thumb. (1 inch ≈ 2.54cm)

2. The common grading standards of domestic coffee:

According to the sieve hole 6.5, 6.0, 5.5, 5.0 mm is divided into five levels. First class: more than 6.5mm, full and complete particles. Second class: 6.0-6.4 mm, plump, more uniform.

Grade 3: 5.3-5.9 mm, fuller and slightly less uniform. Level 4: 5.0-5.4 mm, with incomplete rice, accounting for more than 75% of the total.

Level 5: less than 5.0mm, incomplete rice, complete accounted for more than 30%. International standard rules for inspection of defects in small grains of coffee:

It is graded according to the number of defects, and is often identified by how many defects are contained in a certain coffee bean. According to the identification method of impurities and defective beans in coffee beans stipulated by the International Standards Organization, 300 grams of coffee bean samples were taken to calculate the magazines and defective beans for classification.

Katim has always been recognized by the industry as "instant" coffee, why this is the result, there is only one reason. Katim is a large area of planting introduced by Nestl é in Yunnan, while Nestl é does instant only requires quantity rather than quality, of course, more is the ignorance of coffee farmers. Catimor, a hybrid of timor and caturra, was developed in 1959 by the Portuguese Coffee Leaf Rust Research Center (CIFC). It was popularized in Brazil in 1970s and 1980s, and coffee leaf rust crisis broke out in Central and South America from time to time also contributed to the application of catimor.

Knowledge: in 1892, French missionary Father Tian successfully planted coffee in a place called Zhukula in Yunnan, where there are still 4 coffee plants that are more than 90 years old.
