Hello "Spice"
Welcome to the Coffee Forums website.
I read your question about a coffee roasting class, and I wasn't sure what you're looking for.
Are you a beginner, or do you have some coffee roasting experience? Are you someone who is trying to organize/sponsor a coffee roasting class?
If you do an Internet search, you will see that there are plenty of training facilities where people go to learn about the art of roasting coffee.
Here are some of the topics that many of them cover in their introductory classes.
Green Coffee Origins
History of Coffee Roasting
Green Coffee Grading
Roasting equipment
Roasting
Blending
Cupping
Making Specialty Coffee Drinks
Food safety, etc.
We have several members, of this forum, who have plenty of roasting experience. Feel free to ask questions.
