I did my first AG about 3 weeks ago. 6lb chocolate wheat and 4lb pilsner. OG was 1.042. Fermentation started strong for about 72 hours and then slowed down to almost nothing. I didnt get to excited until it stopped completely, at FG 1.022. I re-pitched the same yeast, Nottingham(not the 11/2012 batch) after 4 days and nothing. So I went and got some yeast nutrients and pitched for a third time (Nottingham) and nothing. The temp is between 62-64F constantly. I could warm it up but I chose Nottingham because its supposed to work down to 58F. Its been stuck at 1.022 for a week and there is no sign of life.
