Using the same yeast on a Northern Brewer Surly Cynic partial mash recipe, I've got about 1/2 inch of krausen after 16 days (!!) in the primary. What's more, NB says that the apparent attenuation for this yeast is 72-76%, but with OG of 1.053 and current SG of about 1.01, I'm looking at attenuation of about 81%. That's high enough that I'm actually doubting my gravity reading. Flocculation is also supposed to be high, which should mean more yeast settling out, not less. All of this has me a little confused. I've never seen krausen in the primary after even 1 week.
I'm going to swirl it a bit, wait a couple days and take another gravity reading, but if I'm already at the high end of apparent attenuation (or beyond) for this yeast, I doubt it's going to change.
This was our first partial mash, and our first use of an outdoor propane burner, and... I don't have high hopes. We couldn't keep the mash temp steady, and I think we scorched something during the boil, based on the sediment in our first gravity sample. Lots of learning that day. I wonder if that could have anything to do with it?
