I am a long time coffee lover and just recently decided to start roasting my own beans. After a little research, I bought a Hearthware I-Roast and a sampler pack of coffee beans plus a couple pounds of other green coffee beans. To date, I have not produced anything that tastes or smells remotely like coffee. The beans get the appropriate attractive color, and look as if they ought to be good but forget it. Unless I roast them really dark, approaching a light vienna, I get a little in the way of aroma and a dirty dish water taste. Can anyone give me some advice? Thanks..
