Instructor - Organic Acids Kit (+ 2 acids)
Preparing for the rigorous Q-Certification exam? Or simply interested in learning more about the role of organic acids and their impact in coffee quality?
Then we highly suggest get a hold of our "Organic Acids Taste Kit".
Developed by coffee scientist Joseph A. Rivera and co-developer of the Q-Certification program, this kit will provide with six (6) of the most common organic acids found in specialty coffee. The protocol which has now become part of the Q-Certification exam, was based on years of research in understanding the role of acids in coffee quality.

Q-Grader Breakdown
Of these a critical piece is the ability to identify and differentiate the four most commonly found acids (ie. citric, malic, phosphoric, acetic) in coffee. Testing a student's ability is what is know collectively as the 'matching pairs' exam for the Q-Grader exam.

If you're making the $1,500-$2,500 USD investment to get 'Q-Certified', then we highly recommend you purchase a organic kit to help you practice before enrolling in the course.
Organic Acids Kit / Q-Grader Matching Pairs / Practice Kit
This Instructor Kit is intended for use in a classroom setting or Q-Certification course. Unlike the Student Kit which is only meant for experiments/testing on an individual basis, this larger kit is for use with groups of 12-20 people per session.
The kit is composed six (6) 125mL bottles of the following acids.
- Citric Acid
- Acetic Acid
- Malic Acid
- Phosphoric Acid
- Lactic Acid
- Tartaric Acid*
*Tartaric is not found in coffee but is only used here for experimental purposes.
The kit includes a 25ml graduated for easy measuring of acids into coffee.
Instructors using this can run multiple sessions of 12-20 people for a Q-course (or approximately 60-70 students), depending on actual usage.
NOTE: All acids are made of food grade purity and in compliance with the Coffee Quality Institute's Q-Certification standards.
