I recently used some Nottingham yeast that I had saved following Bernie's yeast washing thread. It had been in the refer for about 4 weeks when I decided to pitch it on to a batch of my Blonde Ale. I warmed it up to about 70* F and pitched about 3 cups worth of slurry into 5 gallons. It has been fermenting for 14 days at about 64* and is still only down to 1.014 from 1.053. This beer usually ferments to 1.010 in 7 days at this temp when I just toss in packet of Nottingham( not even rehydrated), so what gives?
