Roasting coffee at home is difficult and not worth the effort.

To the contrary! Since being turned on to coffee roasting a while back (after a visit to an organic coffee plantation in Nicaragua), I regret not having started sooner. If you want better, cheaper coffee for little effort, read on. If you like Charbucks – err, I mean Starbucks – coffee, don’t bother.
- Process: A coffee roaster can cost as little as $130. It looks sort of like a blender and works by blowing hot air up through the beans to agitate and roast them. Add the green (raw) beans, turn on, and forget – it’s that simple. You can vary the type of roast (light, medium, dark) by varying the roasting time and/or temperature. This process will generate some smoke, particularly when making a dark roast, so be forewarned. There are also drum smokers that heat the beans in a rotating drum.
- Savings: Green coffee beans, easily available over the internet, cost in the $5-7 / pound range with a few exceptions for super-premium beans like Jamaica Blue Mountain. Beans lose 15-20% of their weight in roasting, so a pound of roasted beans ends up costing $7.00-$7.50 / pound. Compare that with the $12-15 that high quality roasted beans cost. Your savings will soon pay for the roaster and you’ll be saving money.
- Variety: My favorite source of beans, Burman Coffee Traders, currently lists green beans from Costa Rica, Hawaii, India, Brazil, Colombia, Ethiopia, Guatemala, Indonesia, Jamaica, New Guinea, Tanzania … the list goes on. Decaf beans are available as well. Plus, you can experiments with your own blends.
So, if you love coffee – good coffee that is – you might want to try roasting your own.
