Hi everybody, a complete rookie here . I have been trying to find out if there is any course or school that discuss everything about green coffee? Like on how to grade them, how does the green coffee trading works, the history of it, how to import them, how to differentiate between good and bad coffee, etc. I have been looking around on the internet, and all I can found is only courses on roasting, barista training. Any guidance? Or maybe anyone can lead me into the right direction? Thanks a lot.
