So, I've been following a ketogenic diet for a short while. Between fiber flour and allulose, a ketogenic diet has been easy to follow because I've had to give up so few things. One thing I would like to have, however, is beer. Is it possible to ferment beer using fiber flour? Forgive me if that's a stupid question - I've never brewed beer before. Have any homebrewers here tried this? How did it go?
