I searched the forum for this, no hits.
I agree on the cost. Do those other clarifiers work on chill haze too?
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.
Trying a similar experiment right now with a split 10 gallon batch of Kolsch. Looking forward to seeing how well it worked. I have a friend with celiac's disease who is willing to be a test subject comparing the batches. I might try to get one of those kits to comapre. Did you measure the gluten content of the non-clarity fermed batch?
My question now is how clear did it come out compared to using some cheap gelatin. I'm about to order from BMW and currently thinking about dropping a 5 tube pack in my cart. Hmm might as well it's only $10. Plus maybe it'll help the wife out. She has a gluten sensitivity it seems.
Hi Amanda,
Clarity Ferm is currently being sold solely as a chill haze reducing agent. I have brewed with it and I have had a professional brewery use it on test batches and they are currently being tested for gluten. The results are still pending. I talked with Charlie Papazian, who also did some test brews with it and had his beers tested by an independent laboratory and they found the gluten content of his beers to be in the sub 5ppm range. I can't say that this will be true for any beer made with Clarity Ferm, but the observations so far have been promising. If you decide to use Clarity Ferm to make a gluten free beer, I would advise you to have that beer tested before giving it to anyone who suffers from any sort of gluten intolerance. Once we have done more thorough testing on this subject, we'll publish our results on our website, so keep an eye on it for more info.
As I understand it, Clarex is an enzyme derived from a mutated bacteria, a genetically modified organism or GMO.

According to the DSM website it says the enzyme they use is from a cloned strain of A. Niger. This is a mold that can cause serious lung infections in humans, especially immunocompromised. That being said, my friend is a gluten intolerant M.D. who has given up beer. I called her today and told her about Clarex and gave her all the info I could find. She said she would be the first in line to try the "gluten reduced" beer. She said she had tried the damm estrella with no side effects so the clarity ferm sounds promising. I'm going to split an 8 gal batch 5/3 with the clarity ferm for the 3 gal batch and send her a beer or two. If it works out she said she'll buy a 3 gal keg just to keep in her fridge.
I'm looking forward to positive feedback from her. This could be huge.
Thanks for clarifying that part. I forgot to mention it's harmless as a brewing adjunct.
I was going to email Chris @ White labs but it would appear you and Charlie could answer my question. Is there any harm in adding more clarity-ferm for higher OG's? Would I add the extra proportionately depending on the gravity or should I just add 2 vials for anything over 1.048.
Now that I think about it, 1 vial should work for 3 gal of 1.062 wort if you can scale it that way.
This is a great thread and I really appreciate all the effort you've put into this.
Thanks,

Here's the email response. Hope this helps everyone out.
Hi Mike,
The pitch rate is 1 5ml vial per 5 gallons, regardless of starting
gravity. The enzyme is very specific and only targets the protease protein
and it will continue working until there is no more protease left, then
stop. Adding more enzyme will simply make it work faster, but there's
really no advantage to it working faster so I would recommend sticking to 1
vial.

I am more concerned about the gluten-free aspects of this enzyme. I have 3 celiacs in my family and all of them would give the world to just get a good beer and a slice of pizza. Unfortunately I cant help them with the good pie, but if this stuff lets me make "normal" beer that they can tolerate, this would be AMAZING. I
just picked up a pack of this stuff today. Going to brew this Saturday. Will post back with results later. Does anyone have any idea how long it takes for this stuff to do its thing? Would it take longer than a 4 week primary/secondary timeline?
