Why is my beer cloudy?

[Twopan]

I have had batches inexplicably refuse to clear, same recipe, same process, but one batch clears rapidly and another looks like pea soup after two weeks. It's happened a couple of times to a Malt Miller Leffe clone (all grain). I always add protofloc and brewbrite at the end of the boil but it's still inconsistent. I have found that being tempted to bung it it in the fridge after two weeks has no effect. The only thing that works is time. Leave the bottles in the shed/garage at cool, but not cold, temperatures for as long as it takes. My soupy Leffe eventually became as clear as a bell.

That Leffe clone has high protein malts pilsner and wheat which require change of process to clear, e.g.

• mash protein rest - break down proteins
• high mash calcium ppm - precipitate proteins
• 90min boil - break down proteins
• faster chill - precipitate proteins

It looks like the OP is brewing from an extract kit therefore advice re mashing and boiling and grain crush etc. whilst they are valid points for all grain I’m not sure they are really applicable in this instance. I suggest that time is your friend here I have known some kits to take 6 weeks or more to drop bright. I only brew the occasional ‘sticky’ beer kit nowadays but always use BrauSol to help to clear them. Again not helpful as the beer is already packaged but maybe worth considering in future brews.
