Hi all,
I'm interested in getting into coffee roasting purely as a means of producing good coffee in the varieties and taste profiles I want (I don't want another hobby). Are the PID controlled roaster options + proven roast recipes/profiles going to produce something...

Been killing me to keep this under wraps, but for the last few weeks I, along with a few others here, have been testing out Option-O's upcoming 98mm Mizen burrs that they designed for their P100 and upcoming Lagom 01 grinders.
