I am doing a lager, it has been about 11 days, fermenter at 50 F. I was going to check to see if the gravity was low enough to start the Diacetyl rest, but I thought the Krausen should have dropped by now.
There is still the nice brown layer on top of the wort and the bubbles come about every 8 to 10 seconds.
should I wait until it all drops to the bottom before I check the gravity reading?
