I'm at the point of having a steady SG (1009) for the past 5 days on my 3rd Cooper's Lager package. It's been in primary for 3 weeks as of this past friday. I always get a golden colored beer, much like what you'd see from a bought beer in a can or bottle (Bud, Busch, etc.). This beer has turned a brownish color. Not like a stout, more like a muddy water from the Mississippi Delta color. No reddish tint, just a dull brown. I spent Spring Break away from home with my Grandson, and my Step Dad pulled the Kraussen Collar off for me, with strict instructions to do nothing but lift the lid, pull the collar off, then replace the lid. He says that that is all that he did. The temp has stayed at the same that I always run it (22-24 C), but it has a rather unattractive color to it. Any ideas as to what may have happened here? It smells fine, I sniffed it as I was worried about it. I was planning to bottle it, today. Do y'all think I should be concerned about it? Any suggestions?
