I know it's a living culture and I can't make it from scratch, but
I am interested if it's possible to harvest a new yeast culture out
of kraeusen. Somewehere on webI read about old trappist brewers
who were knowledgable enough to collect kraeusen and grew a new
culture whichwas also improvimg a taste with each new generation of
their kraeusen cultured yeast. What's the procedure called ? Please
can someone point to a web page which explain the process, or
explain such yeast harversting. I was searching sites [url]www.byo.com[/url]
and [url]www.reelbeer.com[/url], and could not find anything related about
usefull purpose of collecting kraeusen.

Thank you.
