Cloudy beer question

[gazzatrone]

I have a brew that I put into PET bottles. was crystal clear until I put it in the shed (ie cool place like it says on the tin) to mature and now its gone cloudy.

Any reason for this?

Chill haze, it happens sometimes when beer is.. chilled, if you warm it up again it will go away.

Cheers for that, was wondering if the beer had spoilt. Not tasted it yet as from experience from my first brew that its best to leave it a couple of weeks to mature.

Pewter tankards?
