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
Thank you.
