Q Grader (CQI)

The Q Grader is the professional coffee grading certification issued by the Coffee Quality Institute (CQI), an independent non-profit organization. Achieving Q Grader status grants an internationally recognized 3-year license to score and classify specialty coffee using the CQI’s standardized sensory evaluation system. It is widely regarded as the gold standard credential for professional coffee buyers, quality managers, and competition judges. (source: Academia Barista Pro (website, crawled 2026-05-16))
Varieties
- Q Arabica Grader — evaluates Arabica coffees; most common and globally applicable
- Q Robusta Grader — evaluates Robusta coffees; separate track
The Q Arabica Grader is the relevant certification for El Salvador’s Arabica-only production and for Kaiserblick’s quality evaluation needs.
What It Qualifies Someone to Do
A licensed Q Grader can:
- Score coffee lots using the CQI cupping protocol, directly comparable to the SCA cupping methodology
- Issue internationally recognized quality scores used in green coffee trading
- Assign specialty classification (80+ points) to lots for export purposes
- Serve as a credible third-party evaluator for buyers and producers
Having a Q Grader on staff or accessible to a producer is a significant quality assurance signal for export buyers.
Q Grader Instructor
A Q Grader Instructor (rare internationally) is authorized to train and certify new Q Graders. This is the highest-level credential in the CQI system.

Certification Process
Candidates must pass a rigorous set of practical sensory exams covering:
- Green coffee grading (physical defects, density, moisture)
- Roasted coffee sensory evaluation using CQI cupping protocols
- Triangulation tests (identifying the odd sample among three)
- Olfactory identification (SCA/CQI aroma kit)
- Calibration cuppings with reference coffees
The license is valid for 3 years, after which re-calibration is required to renew.
Relevance to Kaiserblick
| Angle | Detail |
|---|---|
| Quality signaling | Green coffee buyers and competition judges trust Q Grader scores; having lots scored or verified by a Q Grader strengthens export credibility |
| Local access | Academia Barista Pro has two Q Graders on staff, including a Q Grader Instructor — accessible for lot evaluation and training in San Salvador |
| Staff development | A Kaiserblick team member pursuing Q Grader certification would be a long-term asset for quality management and export sales |
| CVA complement | The new Coffee Value Assessment (CVA) system from SCA is a separate, complementary framework; Q Grader is CQI’s parallel standard |
Relationship to SCA Standards
The CQI Q Grader protocol is closely aligned with, but not identical to, the SCA cupping protocol. Both define specialty at 80+ points using similar evaluation categories. The Q Grader system has historically been the dominant certification for commercial green coffee grading; the SCA’s newer CVA aims to modernize evaluation beyond a single numeric score.
