Coffee snobs, just last weekend I experimented with roasting my own beans.
The machinery used? A $28 Breville Popcorn maker with slight modifications. I'm not sure if it relates to the fact I roasted them myself, or whether they are indeed well roasted, but I can't get enough! Definitely worth a try, the worst that can happen is that your left with a popcorn maker and some burnt beans!
This is an excellent way of getting in to home roasting, did that for quite a while. Biggest downside is the small quantities you can do at one time and the chaff that goes everywhere, so you end up standing outside carefully watching a popcorn maker rather a lot.
