Organic Acids Kit / Q-Grader 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.
