Green Bean Grading

[gwink]

With rdgs to the Indonesian green coffee grading system.

How much is the bean counts or weight like with respect to the defects?

How do the beans size ie 13/14, 15/16, 17/18 correlate with the grading -G1, G2 and so on? Were other factors like altitude of growing, double picke/triple pick, taken into consideration for the grading?

Not talking abt Latin or Africa grading system.

I know this is an older post (10 years) but I am surprised to see no reply for it....
Most the information concerning Indonesian coffee grading is on this link: The Coffee Quality Improvement Progress | ICEA

Sizes include (S) small, (M) medium, or (L) large bean. Screen size for each unknown mostly because the country has both Robusta and Arabica bean under nearly similar grading.
Altitude is not in the grading, maybe more about the type of plant. (Arabica in higher areas)

(AP) means After Polished
(DP) refers to the Dry-processed
(TP) means Triple-picked
(WP) refers to the Wet-processed
These would be used together: (DP/TP) or (R/DP Grade 1/AP) or (R/WP Grade 1/L)
