Hi guys, I have just kegged my Woodfordes Wherry, ten days in f.v. final gravity 1013, it smells great but has some bits floating on top that looks like dead yeast as it is the same colour as the yeast sludge in bottom of the f.v. Is this unusual and does it mean I have ruined my brew, it is my first kit for a couple of years. I took real care with sterilising everything any help would be gratefully appreciated.
