I took the full package online course offerings a couple years ago. I totally agree with RedSwing. There is some solid information in the course work, but I also came away feeling not any more equipped than before.
That said, I had already been roasting commercially for several years. I had completed the Q program. Through all of this, I had spent countless hours digging up any info I could find on roasting concepts, bouncing ideas off fellow roasters, trying to critically taste and catalogue batches, and just enjoying coffee through experimentation. I felt that the courses would be more equipping if there could be a atmosphere of dialogue. That is no doubt impossible to accomplish via online teaching. I'd bet the in person courses at Boot would address this much more efficiently.
Ultimately, it's good info. It is informative and helpful to the novice roaster. It does not require a ton of money or traveling hassles. It will satisfy some people and leave some others with more questions than answers..... But maybe that's not such a bad thing.....
