Hi guys. Is this an infection? Should I bottle/rack this ASAP? It's not in the beer yet; looks like it started right under my airlock--come to think of it, I may not have sanitized airlock water--is this my punishment? It's my 3rd brew, a witbier, which I actually used only 4 gallons of water for a five gallon recipe (cuz I wanted to prevent blowoff and hey, the higher alcohol content won't hurt right?)...anyway I just don't know if I should drop everything and get my brew out of there. Thanks everyone.
