Hello - In the process of fermenting my first batch of beer. I noticed on Tuesday that the Krausen had dissipated. Tuesday would mark the 1 week point since I pitched the yeast. Is this about the normal speed you would expect. When the krausen falls, is that a pretty good indicator that fermentation is done/almost done? I know that I need to do the gravity check over a couple of days and no changes = no further fermentation - just trying to get a gauge if I should start checking gravity or if I should wait another week. Tks!
