I brewed up my second batch of homebrew a week ago. Its a hefeweizen kit from my local homebrew shop using White Labs Hefeweizen yeast. It had a vigourous ferment from the start. I had to change to a blowoff tube set up on day 2 when my airlock was infiltrated. I left that there for 3 days then put the regular airlock back in. It has now been 7 days and the air lock had slowed to 3 bubbles per minute. I sanitized my secodary and racking equipment and opened the primary bucket to find a pretty thick kraeusen still sitting on top of my wort. I sanitized my lid and airlock again and replaced them. My question is, should I just wait a few more days hoping the kraeusen has fallen by then or just go ahead and skim it off and rack to my secondary?
