I've poured wort onto the yeast cake left in my primary before, and it worked great. Now, I want to know if I can use the yeast left in the secondary fermenter for a second batch?
I brewed, did 10 days in the primary, then racked to secondary for another 14 days. My primary carboy is clean, and I'd like to brew this weekend . . . there is a nice cake of yeast in the secondary fermenter, can I use it?
