I have a keggle that I like to use for BIAB brewing. I've only done it one; I borrowed a big bag from a friend, but I wont borrow the bag again. Instead of getting a big bag, I was thinking I would just use a few smaller bags instead. Can anyone envision any problems with this method. Also, the first time I did BIAB, I had a lot of wort spill out when I pulled out the bag. As a result, my blichmann burner got quite dirty. Any good suggestions for cleaning the burner? Specifically where the flames come out. Thanks in advance.
