I completed by first brew last Friday, ABS Bavarian Hefe, and I just remembered after reading another post, that I may have screwed up and topped of my fermenter with cold,filtered water out of my fridge. It has already went thru a pretty good ferment and the air bubbles have slowed. Should I just wait a couple weeks to look at it? Could it be infected already? I am fermenting at an ambient temp of 61. Will it be ok? Man, this is a great site. I guess I just had a brief brain fart.
