Fresh roasted coffee is absolutely better than using pre-roasted beans. A Kickstarter campaign has funded an innovative coffee maker that roasts, grinds, and brews. There are, however, some major drawbacks to this approach. Coffee roasting produces lots of smoke, as well as chaff and oil. This machine is so compact and integrated it could be difficult to properly clean the roaster.
Smoke is the big problem. If you roast indoors in the same place, after a few weeks, the area will probably permanently smell of coffee and it might even affect wall colors. This roaster can handle up to twelve cups. That’s probably enough smoke, unless you are careful, to set smoke detectors off. Also, roasting, depending on the roaster, can be quite noisy.
I applaud their idea for this 3 in 1 coffee machine. However, I’m not sure it’s practical.
