Advice on clearing

[thrums1]

I have made a batch of the Mangrove Jacks Brute IPA. it has been left to carbonate for two weeks and cleared pretty well. I moved it to the shed, cold place. it has clouded up again, I can not see through the bottles. Is this normal? What causes this?

Could be chill haze...try moving a bottle back inside to see if it clears...if it does you must drink it...for quality assurance reasons...

 

[thrums1]

What is chill haze and will it go away?

 

[Clint]

I think it may be something to do with proteins in the beer.. someone who knows what they're on about will be along soon no doubt ..
Cure...something for future brews. Drink it hazy...if won't harm you.

According to Homebrewing For Dummies, chill haze is “a temporary cloudiness that forms in beer when it is refrigerated, caused by the combination and precipitation of protein matter & tannin molecules during secondary fermentation.... It does not affect the flavour and eventually settles out on its own. The beer also clears up if you allow it to warm up again.”

You can reduce chill haze by adding amylase enzyme to the wort, or by the use of clarifying agents. HfD recommends Polyclar as being particularly effective at combating chill haze, but since Polyclar is actually micro-beads of plastic (and therefore now on the ecological blacklist) you might want to try one of the more traditional clarifying agents.

Interesting. I have taken a bottle out and it is clearing. I don't want to use chemicals or plastics, if I wanted that I would by a mass-produced commercial beer.

Quite right too!
Some clarifying agents are not chemicals, though. Irish moss is a seaweed, for example. I’ve tried that, as well as isinglass (fish bladders!) with varying results. But I’m very happy to drink hazy, even cloudy, beer. Someone I know hates it, however, so I serve his beer in a ceramic mug.

I don't mind hazy beer. it cleared in the heat, so I have popped it into the fridge to see if it goes hazy again.

At the risk of clouding the issue and potentially going slightly off topic may I raise a slightly different aspect to this. If I put a bottle of two different brews I have in the fridge whilst I get 2/3 out clear but have to put the final 3rd into a separate glass as it come out cloudy through yeast lifting off the bottom of the bottle. If I just poured the whole lot in without paying attention I might think I had a hazy whole bottle. I am not over priming and am not getting gushes nor am I serving up young.I would be grateful if anyone can advise how I might avoid this and I wonder whether finings might make the yeast coating firmer in the bottle.

Some yeasts just settle than better others. For me GV12/Notty is one of the best. Other yeasts will cloud up as soon as you move the bottle, more so as you start pouring. So look for yeasts with a high flocculation rate. What may also help you is to keep your beer longer in the FV, better with a couple of days in a cold place at the end, all geared towards bottling pretty much clear beer. And even apparently clear beer will carb up, it just takes longer. As far as finings are concerned, some on here do use you them, I dont, so they can comment on that.

Ok thanks. I only do kits these days so just use the yeast supplied and am a bit surprised to be experiencing this problem with a MJ Helles lager as the yeast supplied is generally well regarded and it lay in the FV for 23 days.

That protein is part of the nutritional value the big brewers filter out and deprive you of.

Enjoy it.
