The closer I get to finishing up my coffee roasting book the more I'm glad that this is going to be a thing that exists. I spent a lot of time hoping someone else would write it so I could just recommend that instead of needing to do the work myself, but there are a few books for the coffee industry that ought to exist that don't seem to and nobody qualified seems to be working on them (I know at least half a dozen people who should write roasting books and only one of them has).
