So what we're doing is we found all of the steel bb's so there is no issue there. We found three large pieces of glass, but of course we are missing a few. We took a clean t-shirt, cut it up to act as a filter for us, sanitized it with Starsan and we're filtering the beer through that. I think that's the most we can do. I doubt any piece of glass or anything with any physical mass to it wouldn't get through that shirt. Thoughts?
