So, I make an AG ipa. Mash temps at a constant 152 from start to finish and everything looked good. Before I pitched the yeast, I decided to try something different and "dry hop" before pitching yeast. 3 weeks later I go to bottle and the beer looks like a muddy brown color. Any ideas what it can be? I did dry hop again week 2 but the color wasn't an issue until bottling time. It tests good as far as gravity etc and tastes perfect but it looks like dirty water.
