If you start roasting your own, you will likely be corrupted by the quality. :D And the cool thing is it costs less than buying roasted coffee. Better quality, cheaper price, what's not to like?
Sweet Maria's has a lot of info on the process, growing areas, roasting stages, that sort of thing. I bought a home roasting book, but found there was a lot more info on the web. There are probably lots of other sites you can check out.
"corrupted by the quality..." very tempting for a coffee lover like me...;-D
I guess I know what I'LL be doing this evening! Ordering green coffee beans and learning how to roast them!
