So I am on my second batch of homebrew. I transfered this to a secondary yesterday and last night I was reading about not putting it into a secondary because risk of oxidation. So now I am like the typical first time brewer and wondering, "Did I just ruin my brew" I think I am over thinking this but I just want to ask to relive my concerns. The concern I have is the dark on top and the light on bottom. Is this normal? Should I not have put it in the secondary fermenter? Also as you can see in the picture there is a small amount of light that gets in through the curtains in the room. Is this enough to skunk my beer?
