I recently attempted my first homebrew, the White House Honey Ale small-batch recipe kit. The brew went pretty much according to plan, and I was careful to sanitize everything as much as possible. The only real hiccup - I made an ice bath in my sink to chill the wort, and I accidentally spilled a little bit of tap water into the wort when I removed the lid. It wasn’t a lot, and the tap water is pretty good, so I figured it shouldn’t make too much of a difference.
After moving the wort into a 1-gallon fermentor, I placed it in my closet. The next morning, about 10 hours later, I noticed that it was bubbling over, so I set up a blow-off tube into a bucket of sanitizer solution, as the instructions directed. I then cleaned and sanitized the airlock and put it back into place as usual once the overflow subsided. Now, most of the foam has gone down, but there seems to be a thick sludgy layer around the top of the fermentor. It seems as if it’s caked on around the top, like maybe residue from the overflow? Is this a problem? Should I remove the wort and clean that off? Any help is appreciated!
