I'd never even heard of it until your post.

Looking into it, the product Brewers Clarex is intriguing and I can definitely see some advantages of using it on a commercial scale. On a homebrewing scale, I'm not as sure it's worth the retail prices I've found for it ($2/5 gallon batch) if the goal is to improve clarity, as other products like gelatin, PVPP, polyclar, etc. are much cheaper, and cold crashing for a few days does wonders as well. Shelf stability isn't really a problem I've run into.

I agree on the cost. Do those other clarifiers work on chill haze too?

Yes. I typically use whirlfloc at the end of the boil, then before packaging I add gelatin and cold crash for a few days that tends to drop out most of the stuff that causes chill haze. I rack to the bottling bucket when the beer is still cold to be sure those proteins don't get back into suspension.

Great. Thanks. For schnitsandgiggles I'm going to try some, I'll let you know how it worked out.

If this is in fact Brewers Clarex, the more interesting aspect is that it might be able to help reduce gluten in beer making it more drinkable for celiacs. For $2 a pop, that is worth it for a 5 gallon batch instead of brewing a meh sorghum beer.

Is anyone able to buy this from a HBS??? Where can I find official info that shows that this reduces the gluten to less than 5ppm? I'm really interested in this, and I am willing to be a guinea pig and to post the results on here. I'm trying to find good GF recipes, and it's getting difficult. However, if I could get a hold of this stuff, I would be very happy to try it out.

I ordered some and it arrived today. I plan to test it as a gluten reducing agent in a stout that I am making for a friend with gluten intolerance. There has been some discussion about it on ***************.

http://www.***************.com/board/f65/brewers-clarex-liquid-yeast-t7726/.

It isn't being labeled as "gluten reducing" or "gluten-eliminating" in the US. But there are a couple breweries in Europe that are using it in barley beers labeled as gluten-free. So far, the homebrew jury is still out on it though. I figure worst case, if it doesn't work, I will just have to drink this failed experiment myself. . .

Polyclar (PVPP) is the only additive product of which I am aware which can reduce chill haze.

In my opinion, the best way to reduce haze is to use proven techniques which don't allow haze precursors (high-molecular-weight proteins and polyphenols) to form in the first place. I dislike additives where good technique and ingredient selection can perform the same function.

Procedures like:

If you use a protein rest in the mash, don't let it go on too long.
Do not oversparge.
Ensure a vigorous boil, which promotes break formation (use Irish Moss in the boil).
Add hops after you start to see hot break.
Completely separate the bitter wort from break at knockout (well, as completely as you can).
Chill the bitter wort as rapidly as possible.
Cold-condition the fermented beer for at least seven days (as close to freezing as you can get the beer).

Ingredients:

Use of a pale malt which is lower in nitrogen and proteins (<11%).
A small amount (~10% of the grist) of adjunct such as flaked maize or rice is a confirmed nitrogen diluent.

Cheers,

Bob
