Interested in roasting your own coffee? You might be interested in checking out Joe Johnston, who is building his own roaster as an act of 'industrial art' and talking a lot about the art and science of home coffee roasting, good coffee, and coffee culture while he's at it.
Joe truly knows his stuff when it comes to coffee; as a co-founder of The Coffee Plantation a little over twenty years ago, he dual-handedly created coffee culture in the Phoenix area. He's passionate about quality, and taught a generation of baristas -- evangelical qualities he brings just as often lately in bringing urban agriculture to Gilbert, Arizona. His musings are definitely worth checking out over a good cup of joe.
