A work buddy of mine lost his racking cane, and couldn't get his siphon going without it, so he decided to decant his beer out of the fermentor into the bottling bucket. He gave me a couple of bottles to sample. It's a raspberry ale of some sort. It is cloudy, but it doesn't seem to hurt the taste - would this cloudiness be cold break proteins or just gunk from the trub? Also, the beer is overly fizzy. No bottles exploded, but it makes a head in the bottle when you open it, and creates quite a head in the glass. What would be the cause of this? Too much priming sugar? Incomplete fermentation prior to bottling?
EDIT: Forgot to mention the beer *tasted* somewhat strongly of alcohol, but I don't think his gravity was off.
