Hello all
I have a lager (Munich Dunkel) that has been happily fermenting in my chest freezer at 50 degrees F for the last three days. Well, I came home this afternoon and it was chugging along at 62 degrees F. I'm not sure what caused my temp controller to increase the temp, but it is now back on it's way down. So, my question is
is it ruined? The last time that I know the temp was 50 was around 9 last night.
