What do I need to roast green coffee beans at home?

DIY Coffee Roasting Methods

You don't need a fancy, dedicated machine to roast your own coffee at home. All you really need is a heat source that will reach at least 370 F. Many DIY coffee roasters take pride in the Frankenstein coffee roasting contraptions they build or modify, but you don't need to solder or modify anything to do a creditable job of roasting your own java. These basic household gadgets will produce excellent roast coffee with no modification at all.

Electric Air Poppers

Choose an air popcorn popper with air vents in the side of the popping chamber rather than the kind with a mesh grille in the base. Place green coffee beans in the popping chamber and run the popper until coffee reaches the desired roast level.

Stove Top Popcorn Poppers

Follow the directions used to make popcorn in a stove top paddle popcorn popper.

Oven Roasting

Spread the beans in a single layer in the bottom of a flat roasting pan or cookie sheet and heat them in a 500 F oven until they reach the desired color.

Stove Top Roasting

Roast coffee in a heavy frying pan or Dutch oven that heats evenly. Stir constantly over a medium flame until the coffee beans reach the desired roast level.

Heat Gun and Metal Bowl

Put coffee beans in a heavy metal dog bowl and direct the hot air from a heat gun at them until they're done.

For all methods:

Remove the beans from the heat source when they reach the desired roast level and dump them into a metal colander or strainer. Pour the hot coffee beans back and forth between two colanders, strainers or bowls to hasten cooling.
