My IIPA has been sitting in the primary for almost 4 weeks. I just looked at it after not seeing it for about 3 days and it's much darker than when I looked at it last. When I pitched the yeast it was dark, 1090 OG, but it lightened a lot to a nice light brown color during the first 3 weeks. Now it's dark brown. Any ideas?
