One of me coworkers is a home brewer. The other day he mentioned that he was getting ready to make a batch. So I asked him what he did with the spent grain and could I have it. He said I could as long as I provided him with a container. I gave him a 5-gallon bucket.
He filled my 5-gallon bucket and a third of a 6-gallon bucket as well.
I'm hoping that I can get more spent grain in the future. It's a free way to supplement their feed.
