It appeared to me like it was growing, i didn't think about it being roastrium blowing out of the chamber. I wiped it down, tasted like chaff and oils. Was thinking about making a tea out of it but decided not to
On a good note Yakster's roast swap will be the first or second run in it after I totally cleaned it out. I had see kind of the same build up on the Bemhor but nothing like this. I would have to say it always smoked more than the B as well. But I'm happy with it and am happier knowing it's not a mold based 'product' and I don't have to clean it out every couple roasts. I had about 20 on the machine when I too that pic. Still messing around with fishing a TC probe in but where the current one is there is a big nut and beans keep getting hung up in it, trying to read up on where to put a K-type and pull the omega's out that are in there.
