Just racked my Schwarzbier to secondary, never racked before so not sure if this is normal or not. Anyway when I took the lid off primary there was what looked like a sprinkling of chocolate powder sitting on top of the beer. I took a sample from the tap and after the diacetyl rest the aroma is smelling much better than 4 days ago, tasted great too. Here's a pic, should I be worried? Only a tiny bit of it went into secondary. I know we get left overs in the fermenter from fermentation but didn't expect stuff to be sitting on top of the beer.
