Noticed this morning (cleaning out my mash tun) that there was a small amount of metallic flecks at the bottom of the tun. After checking a few things and ruling them out, I ran a pound of grain through the Barley Crusher again.
Ran a rare earth magnet through it and knew the problem right away. For whatever reason small flecks of metal are coming off my mill.
My immediate question is if this is harmful? I don't think much made it to the boil and I've never seen this in the final product. I certainly don't want to dump this 5 gallon batch.
Secondly, is this a common occurrence?
