My 5 gallon batch of imperial pilsener is now two weeks into primary. Temp is being held at ~47 degrees F. The OG was ~1.089. I used Bohemian lager yeast (Wyeast 2024) in a starter to get ~250 billion viable cells. (I know I under-pitched because ~400 billion cells are recommended.) I'm not sure how significant it is, but I also made the error of fermenting the starter in high temps between 65 and 78 degrees F. :cross:
I just checked the FG and I am concerned that fermentation might be stuck. It is very high: ~1.040. Maybe I should give it another week or two before being concerned? Yesterday I sat and watched the airlock, and it appeared to release a bubble about once per minute, if that tells you anything.
So my question is, should I pitch more yeast? If so, in cases of pitching later on into the fermentation, how does one strike a balance between the issue of oxidation, with the requirement for aeration for the newly-added yeast?
Let me know if you need any additional info. I've been keeping pretty detailed notes. Thanks!
