I brewed this last Friday as my fifth batch. I used the extract version. My OG was 1.047. The yeast I had planned to use was bad, so on brewday I went to the LHBS and picked up White Labs East Coast WLP008. It took about 16 hours to get good active fermentation (no starter obviously), and the airlock activity stopped within 3 days. I took my first gravity reading this morning. It was 1.020, which quite surprised me. Also there is a full layer of kreusen on top of the beer. I had planned to leave this in primary for 2 weeks and then bottle.
I'm concerned about the whether the gravity will get closer to expected (Beersmith says 1.012).
I'm also concerned about the kreusen. Is that typical of this yeast? Should I move to a secondary to help clarify, or am I better leaving as is, hoping that the yeast in the kreusen is still slowing working?
