I'm interested in brewing 4 consecutive Czech pilsner lagers, reusing the wlp 802 yeast. I have never done this before, and need some advice on how to go about this. If the first round is on the yeast cake for about 3 weeks before I rack it to the corny for lagering, do I rinse the cake and just transfer the clean yeast into my clean carboy, and then add my new wort to the entire harvested yeast? How do I know if there's enough healthy yeast cells for the next lager- proper pitch rates?
Thanks in advance.
