How Coffee Gets Roasted: The Controlled Fire Behind Every “Good Cup”

Green coffee beans don’t taste like coffee. They taste like… grass and regret. So how do they turn into the thing you actually want to drink? In this episode, Nate and Mason walk through what roasting really is: drying, browning, first crack, development, and why “a little longer” can change everything. We’ll talk roast levels, common roast mistakes (scorching, baked flavors), why fresh coffee needs to rest, and how roasters use heat and airflow like a steering wheel. If you liked our Specialty Grade Coffee episode, this one explains the other half of the equation: even great green coffee can be ruined—or revealed—by the roast.
