I have stuck fermentation on my stout and i keep it in a cooler set to 64 for first week at then 67 after main fermentation has died down, little to no bubbling in airlock. However Today my Final Gravity was 1.030 instead of 1.014. My believe my problem is either:
A: I didnt introduce enough oxygen when pitching the yeast
or
B: The yeast got to hot before pitching and killed most of it. (Live in florida and brew outside.)
or C: both.
So to check for under oxygen I reshook the carboy to aerate it but now read online that aerating after fermentation begins can cause stale flavors as well as diacetyl. So did I ruin my beer by doing this. Also if stirring it up doesn't rekick fermentation can I just add another pack of yweast to get it going again?
Thank you.
