I've read on here that some of you buy your coffee beans green and then roast them for the guest after they pick what they would like. It seems like this could be a great touch to a bed and breakfast. Where do you buy your green coffee beans? I buy already roasted beans for about 7 dollars a pound. Would it be cheeper to buy them green? What kind of equipment would be needed to roast the beans and how long does it take? Does roasting the beans stink up the house? I lived near a coffee roasting business once and it always smelled terrible when they were roasting. I look forward to your input on this.
