Why do some of my bottled beer have chill haze?

[guitarguy6]

Hey guys, I recently brewed an all grain batch using BIAB method and some of my bottled beer has chill haze. Some bottles pour a clear golden color and some pour a darker opaque color. If you hold it up to a light you can see little floating things in it. Shouldn't all the bottles have chill haze? I didn't have my worth chiller handy and it took my about an hour of ice baths to cool down the wort. What would cause only some of the bottled beer to have chill haze?

It is temperature dependent.If You put beer bottles in the fridge(or any other cool place), the chill haze will appear but It will disappear when the temp of beer raises to room temp.

Chill haze is formed from dissolved proteins clumping together that'll settle out like a fog in about 3-5 days usually. That's another reason to give bottled beers a week's fridge time. Besides getting co2 into solution for better head & carbonation in the glass. Using Whirlfloc (1/2 tablet) in a 5 gallon batch the last 5 minutes of the boil will give clearer beer later as well.

The operative part of his post was, "What would cause only some of the bottled beer to have chill haze?"

Maybe those are the last ones bottled, when he was more likely to be picking up particles that had settled towards the bottom?

I can't imagine a way for only some bottles to have chill haze unless the bottles without chill haze have been in the fridge a lot longer than the bottles with chill haze.

Because the protein coagulates at lower temperature, if you store at lower temperatures, you can get chill haze to settle out. Bottles stored longer will have less.

But you are sure it is chill haze. It goes away as the beer warms? It could easily be the case that some bottles are more trubby than others or some bottles still have yeast in suspension.

I'll have to check and see if it clears as they warm. I have the bottles in my basement where they stay around 70F. I put them in the fridge a day or 2 before drinking them. I use irish moss tablets when I brew and also use gelatin finings in my secondary.

Both Irish moss and gelatin should work on protein haze and chill haze. Gelatin works best if your beer is below 50F when you add it. The colder, the better.

The only other things you can do is get good hot and cold breaks.

I'm hoping it's just yeast. My lagers and when I use kolsch yeast, the bottles tend to stay dusty-looking longer than when I use ale strains.
