Roasting coffee at home is cheap, fun and you'll have bragging rights to some of the freshest, best tasting coffee around! Impress your friends and subvert the evils of the big coffee business. Your final product will take 10 minutes to make, be about half the cost of roasted coffee you buy at the store or cafe, and your initial setup can cost you $10 or less.
What you'll need
* A fluid air-bed roaster AKA popcorn popper ($10 new @ the corner drugstore, $1-5 at yard sales or thrift stores, see below)
* 1 bowl or receptacle
* 1 colander for cooling the beans
* measuring cup
* green coffee beans
Some poppers will work better than others, but the only detail is that absolutely necessary is air vents that are on the side of the popper, not the bottom of the chamber. See the picture for an example of side vents.
We've had successful roasts with the Poppery I & II, Kitchen Gourmet (Walgreens) brands, but there
are many others. Old popcorn poppers will sell on eBay for $30 ---- that's often because folks are willing to pay a premium to use them as coffee roasters.
There are a lot of excellent coffee roasting tutorials on Instructables! This one is based on an old IRL guide I wrote
