I am currently on my third batch of beer and am concerned about the fact that there is way more krausen on this batch than there has been in the other two. Is it normal for there to be over an inch in the secondary fermenter? I'm probably just a worry wort (pun intended), but I feel like I need some reassurance. It is also bubbling a lot more than when it was in the primary. Hopefully this is just a RDWHAH problem, lol.
