I brewed BM's Black Pearl Porter yesterday and while chilling the wort it developed this kind of skin on top, like fat in milk for example. Anyway I skimmed it off with a sanitized strainer and Im not concerned about the beer really (it's bubbling away). It's just bothering me, Ive seen that before, any thoughts as to what or why?
