So I pitched two packets of rehydrated yeast on Sunday night into 5 gal of 1.064 wort. I am using a 7 gal Speidel fermenter and I usually see airlock activity after a day or so. After taking a peak inside the vessel, I see a thick krausen and smells like fermenting wort. I assume everything is going as planned. Am I just worrying too much? Yeast was US-05 by the way.
