For purpuses of plumbing my fermenter I need to introduce a small piece of copper. The size would be equivelant to a mans wedding ring in a five gallon batch. Anyone know of any harmful effects on the fermentation with copper exposure?
You can fool some of the people all of the time, and all of the people some of the time, and them's pretty good odds.
While I agree that mash is often made in copper mash tuns due to the good heating conductivity of copper, using copper in a fermentor just seems like an awful waste of money.
