Had an online run through on a class I'll be helping out with in a couple weeks. I've station instructed this one a couple times before but it's good to know where things are going to be. The students in my group will be trying to roast a coffee such that they're indistinguishable in the cup between a Diedrich and a Giesen roaster. Should be fun.
Roasting system calibration is something that I've done a lot of work on in developing Typica so it's good that there's external research happening at a larger scale that confirms the results of the work I've done, and having a class where people can prove it to themselves is great to see.
