PVPP will get rid of it. But then you will also have to filter as that is the only way to make sure it is all out.

Yo would need to drop below 2.5microns, but I don't think you are going to be able to get your hands on the PVPP as it not something I would see a HBS carrying.

[S.F.B.]

Chill haze is a non issue as far as I'm concerned. It only effects the appearance. Unless I was putting my beer into a competition I wouldn't worry about it.

Very cold conditioning(35 F) for a long time - 2 months or so - I've read will also greatly reduce chill haze. The chill haze proteins come out of solution and settle out of the beer. You have to rack the beer off of the sediment because when it warms up it is possible for the proteins to go back into solution.

thanks for the info. To convert a few non-believers I have thought
of going the extra mile and make the beer look more like they are accustomed to seeing.

I always use Irish Moss and find it works fairly well. I also tried some Polyclar and it worked very well, but I found it a bit of a hassle to work with.

Like others mentioned, I don’t really worry about the haze, Irish moss is good enough and easy to use. Plus, once the beer hits the glass the condensation on the glass makes the beer look a little hazy anyhow.

Poly-Clar is cool but it contains PVPP in amounts from 20% on up and IIRC it must be filtered to remove the PVPP.

Funny note on Poly-Clar for all you "Purists" out there. This is a process aid and is allowed under the German Purity Laws (rheinheitsgebot). It will aid in the precipitation of proteins and removal of polyphenols known to cause filtration probelms and chill haze.

Brewmonkey,

Thanks for the tip on the polyclar. There is nothing on the packaging indicating that you need to filter…that is kind of scary. I wasn’t planning on using it again, but I definitely won’t now.

Curious, what are the negative affects of PVPP?

What's PVPP?

There's also Claro K.C. finings (SuperKleer, I think?), which is a two part thingie that works OK. It does tend to strip out some of the flavor, too, though.

This page has some info:

An interesting article on beer and additives (http://www.orahsaddiqim.org/Kashrut/Beer.shtml)

PVPP is PolyVinylPolypyrrolidone and aids in clarification by precipitating proteins and absorption of polyphenols.

[Fast_Eddy]

The wizard in this months BYO says that PPVP will settle and you can rack off of it - so it doesn't necessarily need to be filtered out.

Man, that seems like alot of trouble to filter out all the stuff that makes beer so good in the first place....
