Dr. Manuel is coming soon! The origin of coffee - coffee processing courses

WechatIMG1.jpeg

The coffee chain has many steps all with the goal of making a delicious cup of coffee (in speciality coffee, at least).

As Guatemalan farmer and processing expert Nilton Perez says,


“Eighty percent of coffee’s flavor is a gift, you cannot change it.”

Human’s try to be in control of everything, but no matter how hard we try, we cannot change our terroir. If you want to change your altitude or climate, you have to move.

The other 20% of coffee’s flavor can be changed through picking methods, varietals, processing, roasting, and extraction.

One of the growing focuses in the industry is on processing.

There are plenty of books and videos you can watch about roasting, extraction, brewing, etc. But for processing, the amount of science is growing, but some concepts are still somewhat nebulous. Processing is important for farmers, roasters, and baristas to understand. The more you understand something, the more you appreciate it.

Even those that don’t know or understand processing still get excited when they hear some guy named Sasa say “carbonic maceration,” or when their bag of coffee says “honey processed.”

Yea sure, it sounds sexy, but what even is it? And does “honey” process really use honey?

There are several terms in the industry that are probably intentionally complex sounding. I am not sure they should be, but until the industry as a whole has a grasp on processing, this complexity and ambiguity won’t go away.



In March we have Dr. Manuel Diaz coming to teach us about processing.



Dr. Diaz is a leading expert in the coffee industry in processing and has consulted farms in over 10 countries.
