CSC-2: Los Angeles, CA

Coffee Science Certificate

March 24-26th, 2020 - POSTPONED
Los Angeles, CA


For those who have completed CSC-1, we welcome you back, this time to our second level CSC-2 course!

Unlike CSC-1 where we focused on coffee as a 'raw product', in CSC-2 we will focus on coffee as a 'semi-finished' product and explore its chemistry. This new course will focus primarily on the processing stages of coffee, namely the chemistry of coffee roasting, aroma formation, olfaction, decaffeination technology and a more advanced section of organic acids. The course will run a 2.5 days and will include both theoretical and hands-on exercises to convey key fundamentals in this second level track.

General Questions

What is the CSC certification program?

The Coffee Science Certificate (CSC) is the first and only coffee educational program focused on coffee science.

The program is composed of three tiers (CSC-1, CSC-2, CSC-3) each with a specific goals and objectives.  

What is the structure of the program?

The seminar is approximately 70% lecture/theory with the remaining 30% hands-on practical exercises. 

Do I need to take each of the three tracks in order?


Since every track builds upon the previous track, we require every student to complete and pass preceding tracks before moving on to more advanced material. This allows us to get further along without having to repeat (and annoy) other students.

Will I get a certificate when I pass and complete the course?

Yes, you will receive a printed certificate. For those who registered late, we will mail your certificate to you 2-4 weeks after the completion of the course.

Will we cover Brewing & Roasting Chemistry in this class?

Although we will briefly touch on a few technical aspects of brewing/roasting, please note that these are covered in much greater detail in tracks CSC-2 and CSC-3.

For details on this specific session please refer to the program details for more information.

Who are these training sessions targeted for?

These seminars are intended for a wide range of coffee professionals including: producers, importers/exporters, roasters, quality control, cuppers, Q-graders, technicians, product development, baristas, cafe owners, etc. 

All materials presented is targeted towards professionals that may not have a technical/scientific background, but would like to expand their knowledge of applied coffee science.

Even if you've been in the industry for a while, we are confident that this seminar will greatly increase your technical knowledge base of coffee.

What should I expect from this session?

Expect to learn a lot!

You will gain a much better understanding behind the science of taste, aroma development and overall coffee chemistry from 'bean to cup'. All sessions will be presented in more of a formal lecture style with occasional hands-on labs. Expect to take notes and be an active participant throughout the lecture!!

I'm Q-certified grader, will these seminars help me?


We are confident that these seminars will provide a greater technical understanding of coffee from a scientific perspective.

Over the years we've trained hundreds of certified Q-Graders and many would consider the content covered in these seminars as the 'next step' to earning Q-certification.

As a barista will these sessions help me professionally?

Yes! These seminars are intended for anyone seeking a better technical understanding of coffee from bean to cup.

Will I learn the latest tricks in latte art in this seminars?

No. Unfortunately we will not be discussing issues related to espresso beverage preparation or latte art - as that is not the objective of the seminar.  

Will this be another cupping class?

No, this is NOT a cupping class.

For those seeking to hone their cupping skills we highly recommend you enroll in an introductory class from SCAA or any other private training facilities. Although not required, we highly suggest students have at least two years of experience and have a basic understanding of coffee processing before attending. 

Will I become a "cupping expert" once I have completed this seminar?

Becoming a great "cupper" takes years of practice, practice and practice. Although we do not guarantee that you will walk away a “cupping expert” - we are confident that you will walk away with a much greater technical  knowledge than that of your fellow peers.

Will these seminars prepare me for international certification?


If your planning on becoming a Q Grader this seminar will assist you in developing a strong technical foundation to further expand your coffee knowledge.

Your instructor - J.Rivera has been a coffee chemist for over 10 years and has developed numerous de facto testing modules for both CQI and SCAA that are still in use today. Exams designed and developed by J.Rivera include the Sensory Skills Exam (parts 1-3), Organic Acid Profiling, Matching Pairs and several others which are integral exams to achieving Q-certification.

We are confident that you will gain a great deal of information in our session and who better to learn from than the original developers of the Q-Certification Program itself (Ted Lingle / Joseph Rivera).

What time should I plan to arrive, what should I bring?

Sessions begin promptly at 10:00AM - we recommend you arrive 15 minutes before to settle in and have a cup of coffee. All that is required is an open mind and a eagerness to learn.

More questions?

Feel free to send in any questions you may have beforehand and we will try our best to answer it during the seminar.
