Well, maybe just some baked coffee that sat in a hot drum.
Because of the weather, the electricity has gone out a few times recently. Mid roast and you are just out of luck. When the drum stops rotating, there is nothing you can do to save the roast, you are just thinking about avoiding smoke or even fire at that point. I guess we are lucky though, we installed a flame sensor/safety valve like on a home heating system so if the electricity goes out, the gas cuts off automatically. Same deal if it goes over temp.
