I think that is what it is called when you pitch a fresh batch of wort on the yeast cake from a previous primary fermentation. I am brewing the same Fullers ESB recipe on this coming Monda and could Save myself 5 or so bucks by reusing the yeast cake from this batch of ESB. How should I go about doing this. Pour Right ontop of the yeast cake or pitch that yeast cake ontop of the new wort in a fresh fermenter?
