What is Fine Robusta? Facts Everyone Should Know

fine_robusta_coffee

What is Fine Robusta? – Is a Robusta coffee graded to ” Fine ” by R Grader. R Grader is certified by CQI. The process of grading green and roasted coffee beans through cupping according to CQI & SCA standards. “Fine,” not simply as good or better.

What is Fine Robusta?

For Arabica coffee to be called “Specialty grade coffee”, a lot of coffee needs to be graded by Q grader through 1. assessing the quality of green coffee, and 2. through cupping according to SCA’s standards and rules.

Coffee with 80 points or more is called “Specialty”. The scoring criteria and quality assessment are regulated by SCA (Specialty Coffee Association).

Based on the standards of SCA, CQI (Coffee Quality Institute) has certificates of Q Arabica Grader (assessment of Arabica coffee quality) and Q Robusta Grader (or R Grader, assessment of Robusta quality) issued to individuals who pass.

The 22-part Grader exam focuses on knowledge and skills in tasting and classifying coffee.

CQI was established in 1996 and the Q Program course has been available since 2003. Q Grader must renew its certificate every 3 years to ensure skills and knowledge are always up to date. In 2009, CQI organized a symposium on Robusta.

The first Q Robusta course specializing in Fine Robusta evaluation and grading was held in Uganda in 2010 with the Uganda Coffee Development Authority (UCDA).

Thus, it is not difficult to see that:

Evaluation criteria “Fine Robusta”

Like the Specialty Arabica assessment standard, the Robusta assessment requires two steps:

Green coffee quality review

There are 2 types of defects: Primary (main defect) and Secondary (secondary defect). Primary defect includes errors such as Full black (completely black coffee), Foreign matter (there is a foreign object in the coffee sample), Fungus or Mold (mold or fungus coffee), Severe insect damage (insect damage).

Do secondary defects include errors such as? Broken/Chipped (broken beans), Partial black (partial black bean), Partial insect damage (partial insect damage).

What is Fine Robusta? Full Black vs Partial Black.- “Fine Robusta Standards and Protocols”
Another concept is Full defect. Full defects can include 1 to 5 Primary defects or 3 to 10 Secondary defects. For example, 1 Full black particle (Primary defect) is considered as 1 Full defect. But 3 Partial black particles (Secondary defect) is 1 Full defect.
What is Fine Robusta? “Fine Robusta Standards and Protocols”
For each sample of 350gr of Robusta coffee, for the coffee to be in the “Fine Robusta” threshold, the sample must not have a Primary defect and only have less than 5 Full defects from Secondary defect.
Example: As long as a foreign object such as a rock, twig, or dried coffee pods, this lot is not immediately labeled “Fine Robusta”.

Under “Fine Robusta” is “Premium Robusta”. To be considered “Premium”, lots and samples must not contain more than 8 Full defects (including Primary and Secondary defects).

Example: Sample has 1 grain of Full black + 1 grain of Full sour + 3 seeds of Partial black = 3 Full defects. This is still a “Premium” bean.

Judging quality by cupping

CQI has its own regulations on how to cup Robusta. Sample Robusta coffee must be roasted ‘darker’ than Arabica ( Agtron gourmet color 48 with unground coffee, 78 +/- 1 after grinding).

Cupping with the ratio of 8.75gr coffee:150ml water. The remaining regulations such as water quality, degas time before the cup, water temperature, cupping table area, etc. are all very clear but I will not mention them all ^^

The biggest difference in Robusta cupping can be seen in the Cupping form. With the SCA Cupping form for Arabica, you can see:
