Anybody have a good recommendation for a book to read about coffee roasting?

I would like recommendations for both technical/scientific and nontechnical/nonscientific.

Thanks,
Blake

Ken David's and Scott Rao's books ought to take care of those requirements quite well.

Highly recommend Scott Rao's book.

Spend some time in the roasting forum here. In fact, do a search on books here. One of the interesting results I found was a comment by one of the roasters I have a lot of respect for. He says most of what he learned, he learned in the roasting forum. I agree with that. There's an awful lot of good information here. The books already recommended are good. I have them. But seldom refer to them. Instead, when I have a question, I check it out here. Also, there's a wealth of information on roasting at the Sweet Maria's web site.

I've gained tons of info here...Scott Rao's book helped pull a lot of that together for easy reference...It's been the single best tool for my roasting progress so far.
