Title: Reusing the yeast cake and aeration
Post by: delzep on May 16, 2014, 06:26:48 AM
Planning on bottling a batch while I brew and use the yeast cake to dump my secondbeer onto. How do I go about aerating the wort though (normally done before adding yeast). Use an extra fermenter ?  Boiler - spare fermenter [stir like mad], then transfer to yeast cake? I'm guessing  boiler to yeast cake then stir is a bad idea?

I decant the yeast into a 3l conical and give it a wash. Let it settle. Pour off the water and put the middle later if milky test in the next batch leaving behind the dead yeast  and sediment from the last batch.

Best to clean your fv out completely.

I would make sure you use a pitching calculator so you only pitch the amount needed
so try this one

Select repitching from slurry and adjust the parameters ..
