I’m bemused by the community of hard-core home coffee roasters. Here, for example, is a roaster using an air-type popcorn maker.

This is a pretty common technique, and the folks over at Evil Mad Scientist (great kits!) developed some sort of bean cooler. Being engineers, they went pretty hard-core. Check it out here: EMS Bean Cooler.

I started saying I was bemused, because this is the coffee roaster I used in Puerto Rico:

That’s right.: A wood fire. Cans with rocks. A pot. And a stick.

Sometimes you have to take off that over-engineering hat and just start a fire.
