Four days ago I brewed a beer and went with my own grains. I'm doing an extract beer and selected my own grains from the brew shop. They milled my grains for me there and I used almost the same kind of cheese cloth that comes in a kit. The only thing is my steeping time ran about five minutes past the average 20 and the temp got to about 180 before I yanked the grain bag out. Could this have contributed to a big time haze in my primary? It almost looks like dirty water. The smell comming out of my air lock is awsome though. A beer thief sample yielded a great flavor with only 4 days of being in the fermenter. Any reason why it's so dirty looking?
