Kreusen has not fallen yet

I brewed a cream ale 12 days ago. Was planning on kegging tomorrow. Checked the carboy today and noticed there is still a good 3/4" of foam on the top. I normally primary in buckets so maybe this is normal but usually when I look in the airlock hole there is just beer. Any ideas?

Check the gravity and if it’s done, swirl the fermenter to knock the krausen down, see if it stays down.

I’d say just give it a couple more days then check again.

Take a gravity reading today. Take one again in 2 days. If it doesn’t change package it.

The kreusen may not fall until long after it’s done.
