How can I easily roast a great coffee? What are the most important decisions, tricks and techniques to better roast coffee? What equipment do I need? And how can I translate a roasting profile from one machine to the other?

There is so much information on coffee roasting around, but it's hard to distinguish, what is right and wrong and much more - what is relevant and what isn't. Therefore I am thrilled, that such an experienced roaster, educator, researcher and author like Rob Hoos took an hour to share his knowledge and experience with us.

What was planned as an interview on roasting has become a profound overview on the fundamentals of coffee roasting. There is so much to learn in every sentence of this interview. So use the opportunity to watch it twice, three times or even more and don't forget to take notes.
