So I have now pitched my wort on the same Yeast (WLP0001) for the third time and it seems to ferment faster every time. Initial took about a week to ferment, cause it was building up the yeast culture, the second time took about 3 days, and the last batch I did was done fermenting in like 1 day. I assume this is normal. Anyone else used the yeast cake over and over and notice fermetation times going down? I guess I'll have to check the F.G. to be sure.
