I have shipping addresses for participants in my next class so I'll be packing up boxes of coffee and shipping to them soon. What I'm doing is 10 roasts of one coffee where the roasting plans hit 5 different ending temperatures across a range of light to dark, 2 different profiles to hit those end temperatures, and some unroasted coffee so people can taste those roasts, look at the roasting data, and then think about how they'd approach that coffee or improve on that and they can try their idea.
