Product Details
Chill haze is caused when proteins and tannis (polyphenols) bind together and become insoluble during cold storage. Clarity Ferm prevents chill haze by breaking down the proteins involved thus preventing protein/polyphenol complexes from forming. Clarity Ferm also significantly reduces gluten content in finished beer. Treated beers usually test below 20ppm gluten, the current gluten free standard. Each vial contains 10mL of Clarity Ferm - enough to treat one 5 gallon batch of beer. Simply add to cooled wort when pitching yeast.

A welcome development
This is as easy as it gets. Beer comes out cleaner than otherwise, particularly for cold lagered beers. The added benefit of precipitating gluten with the other proteins has made my gluten avoiding friends pretty happy as well. The only negative is the price but I have hope that it will come down with volume sales.

A Celiac, and brewing again
After I found out I was Celiac, I thought my Brewing hobby was over. The existence of this product has enabled me to brew a dozen batches of beer that I can tolerate without symptoms.
One vial is enough for a 5 gallon batch. Add to primary. Zero effect on flavor!

Does a good job of clearing beer. The factory stamped dates on the back are poorl labeled and confusing. First date is manufactured date, the second one in a Use By date. Best stored in the refrigerator.

Clarity Ferm
I have been using it for a while now and can't tell the difference, although my gluten free friends certainly can:)

Reduces gluten while adding clarity to the beer
My wife loves beer but the options available on the market for those who are allergic to gluten are limited. I can basically make the style of beer she prefers and add the White Labs Clarity Ferm to reduce gluten to approximately less than 20 ppm on a 5 gallon batch. This worked succesfully on an amber ale I made her in the spring and I now have a batch of caribou slobber brown ale the is in the secondary fermenter. My wife has been able to enjoy without any allergic reactions. I have noticed that the beer is also clearer than what I brew for myself.

Clarity Ferm
Very easy to use! This is the first batch of beer I have brewed with Clarity Ferm to reduce the gluten content. The batch will be bottled near Labor Day (2016). I'm looking forward to the results!

Celiac disease sufferers rejoice!
The value of this product (to me anyway) is that gluten levels are reduced in my homebrew. I had some celiac friends sample beers brewed with Clarity Ferm and to date, every beer has passed the test, and those friends are even more friendly now! I'm sure part of it is that my beer tastes so good, but more importantly, they can drink beer without discomfort. For that reason alone, a vial of Clarity Ferm will be in every batch of beer I brew going forward.

Works as advertised!
This stuff eliminates chill haze, exactly as advertised. Just pitch the vial along with your yeast. It also nearly eliminates gluten, if that's important to you. It won't help drop out other haze material from your beer the way Whirlfloc does. I use Whirlfloc in the kettle, and Clarity Ferm in the fermenter, and my beers are very clear.

On a two fermentation product, would it be just as good to add it to the second fermentation?
A shopper on Nov 28, 2016
BEST ANSWER: It says you should add it during primary. I think this may be that the enzymes are more effective when there is no alcohol present. I have seen this scenario with other enzymes used in the fermentation process.
can I use samll amounts of this in my one gallon small batches?
A shopper on Oct 26, 2017
BEST ANSWER: Yes. I used a full vial for a 5 gallon batch so you could use about 1/5 and get the same results. Works very well! Cold crashing will help as well. Cheers!
Are you supposed to just pour it in right before pitching yeast, or does it need to be stirred in before pitching yeast??
Matthew F on Feb 24, 2018
BEST ANSWER: Just pour it in after pitching the yeast. Do not stir. I used it and it seems to work but I have also used gelatin finings which work great at a fraction of the cost. If you have not purchased clarity ferm then I suggest you don't. The gelatin gets used after secondary fermentation when racking to a brite tank for 3 days in a cooler. The gelatin will also remove yeast, clarity ferm will not.
Will this product affect those with shellfish allergies?
A shopper on Nov 15, 2017
BEST ANSWER: Sorry...I cannot answer your question about shellfish allergies, but am highly doubtful that Clarity Ferm would work for that. I read an amazing article about how Clarity Ferm works to reduce the gluten content of beer. Basically, "gluten" is a specific protein chain. People with Celiac's disease (gluten intolerance) are allergic to this specific protein chain. Clarity Ferm works by snipping this protein chain in two via an enzyme. Once the protein chain is snipped, it is no longer "gluten" and does not affect people with Celiac's. The two halves of the gluten protein are not the same as the single whole. Sort of amazing really. Because the protein snipping is so specific to gluten, I doubt it would work with whatever causes shellfish allergies.
What affect does this have on the taste of the beer?
Antonio L on Mar 5, 2016
BEST ANSWER: It acts mostly to remove gluten and inhibit chill haze. This may have very subtle impacts on taste, but is not something that is noticeable.
Can this be used in addition to Whirlfloc as well?
Neil K on Feb 24, 2016
BEST ANSWER: Yes, you can use this with Whirlfloc for extra help in clarification.
Will this eliminate gluten levels in any of the beer kits on this site? I'm still very new to this. I would like to make a brew my wife can enjoy with me (gluten allergy).
J A on Feb 10, 2016

Well, this product will definitely reduce the amount Gluten, and it can even reduce the levels of gluten to below what is measurable in some labs. However, technically I don't think it can eliminate it altogether, and a lot is going to depend upon how sensitive a person is to gluten. At least, that's my understanding. As far as I know, Clarity Ferm's effectiveness at reducing gluten has less to do with the kit/recipe being brewed, and more to do with how it is used and how sensitive a person is. I have a lot of friends who are gluten intolerant, and I've done some research into it myself. The most insightful thing I've come across is this podcast about an experiment a professor did at a college in Michigan:


However, I would also like to refer you to White Labs themselves:


This link has plenty of info and other links to the way professional breweries use it.


I see the label says to pitch with liquid yeast - what about dry yeast?
John R on May 26, 2016
BEST ANSWER: It will work with dry yeast too.
