Funny you should ask. I roasted my first batch yesterday. I am enjoying it right now. Columbia Antioquia Spremo. You are correct, it is not very difficult, however, there does seem to be a timing issue. My coffee is extremely good. Wow! What a nice surprise. I will try to roast my next batch a little longer. I like my coffee very dark roast, but was a little tentative with my first roast given the instruction warn against fire! I would suggest any coffee lovers try it. I have a sampling of beans to try---yeah
