My bottled brew carbonated and is clear. It was in the fermenter for 3 weeks. When I put it in the fridge, it got cloudy. Never happened with my Mr. Beer experience. Will it clear? About how long?
Sounds like you have "chill haze". Many things can cause it. It is common and nothing to really be concerned about. Quick chilling of the wort is one way to avoid it, but there are several reasons why it may pop up.
