So i cannot post a picture because i do not own a digital camera, so i will do the best to describe what i am seeing. My beer is in a glass carboy secondary right now. On the top of the beer is this cream/light tan colored sea-foam looking stuff. Now i was originally thinking i raqcked to early and it hadn't fermented all the way out. Its not going away however. In fact it seems to be growing.... Any thoughts???
