I brewed a pale ale (OG 1.058) using us-05 on 7/30/11 and fermentation had stopped (1.024) by 8/10/11. I used too much crystal. Took readings for 3 days, stirred wort to get yeast back into suspension, waited 2 more days and nothing. I added one crushed tablet of Beano on 8/12 and gravity got down to 1.022, but have taken readings for another 4 days and no more fermentation has taken place. So i pitched a packet of Nottingham and now it is happily fermenting away. My question is since the beer has been in primary for almost 3 weeks now, how long should i let it condition once the Nottingham yeast is done?
