So, after brewing today and getting a stuck sparge, I disassembled my mash tun to check it out. I had put a spring in the stainless steel braid to keep it from collapsing, and it looked pretty corroded/rusty. Though this was a stout, and could have made it dark? This is only my second mash using this spring.
is this batch going to be unsafe to drink? I'm a little worried, cause I'm not sure what the spring was made of, I thought stainless steel, but its obviously not!
Is rust dangerous?
