I hope somebody will be able to help me with some issues related to the BIAB method. I've been preparing beer several times in this way and the taste was very good. However, what constantly troubles me is efficiency. I'm always about 55% and I do not know where I'm wrong. I have done sparging...

Regards to all, could you help me how to determine brewing efficiency? The other thing, whenever I put beer into a secondary fermenter or bottle, remain crumbs of yeast. How can I get rid of that? Thanks in advance, Borko
