bracconiere

it's been on my mind for other reasons.
and would a pelicle make you sick?

B-Hoppy

I found a research article a few years ago when I was getting started and the biofilm had a bunch of fiber, protein and lots of other good stuff in it. That gross looking thing was the biggest hurdle for me to get over when I started brewing it so I decided to eat one. It actually reminded me of pineapple in both flavor and texture.
As for the booch going bad, I would have to say no. As long as it was well made and bottled, the pH should be low enough to keep anything from starting up in it. There's always lots of variables but from what I've found is that the pH drops down into the 2's and it's really hard to enjoy much of it when it goes that far. Usually time to start a new batch if it ever goes that far.
