Hi all! I just checked the gravity on my Kolsch I'm making, and I found that, even though it's nearing its FG after one week, there is a thick head of yeast at the top that I'm tempted to skim and harvest. Am I asking for trouble by skimming this, given that it's already a very low flocculating yeast and I'm presumably taking the less-flocculent part of it? Or should I just chill out and do it?
