An easy way to eliminate chill haze in your finished beer is to add one vial of Clarity Ferm to your fermenter prior to the onset of fermentation. Use 1 vial per 5 gallon batch.
For the beer geek (but still simplified!):
Chill haze is caused in your fermenter during aging when polyphenols and polypetides bond together. Clarity ferm cleaves polypetides (a protein fraction) so they cannot bond with polyphenols (tannin). This product is also known as Brewer's Clarex.
There are also discussions and testing being done with this product, finding that it reduces gluten levels in beer. Gluten is the protein that Gluten-Intolerant (Coeliac) folks need to avoid or greatly reduce consumption of. Always consult a Doctor first before use in this application.
  • An enzyme that is effective at preventing chill haze
  • Increases shelf-life and product consistency
  • Does not alter beer flavor or aroma
  • Has no effect on head retention
  • Can produce gluten-reduced* beers made with barley (*The majority of beers test below 10ppm gluten when used in the correct dosage)
Shelf life is 6 months.

Trying to make a Gluten Reduced beer for a friend
Nathan Chaney on Mar 16, 2018
Reducing Gluten for the consumption concerns of all but my Celiac friends is good to do, and a relatively inexpensive addition to the total cost of a brew, and it doesn't affect the flavor at all, IMO. I don't know why any brewer ever wouldn't do this.

Can you use clarity firm if you plan to bottle condition your beer ?
rich edson on May 23, 2018
BEST ANSWER: Absolutely. I use it routinely and I typically bottle about 1/3 of my batch and keg the other 2/3. It really does help reduce chill haze. (It is not added as a fining agent after primary fermentation is complete; You add the clarity ferm to your cool wort at the start of fermentation.)

If you or someone special in your life is gluten sensitive, these are a must have.
It was a dark and stormy night. The keezer was humming, the IPA on tap at home was perfect, but something wasn't quite right. There was a commotion, and some gassy shame. It turns out, the love of my life is gluten sensitive. What was I to do? I'm a home brewer. Beer is life. Did I need to make little tiny batches now and drink alone behind the garage? No, no I didn't! Thanks White Labs! Clarity Ferm has reduced the gassy sadness that I thought was my future. Rock on you gluten reducing legends!

Almost Perfect
It definitely makes beer drinkable for Gluten intolerant people. I have a friend that has a severe Gluten intolerance and she has been able to drink all 3 batches I’ve made with Clarity Ferm. I would have given it a 5 star rating but it doesn’t clarify a beer like I had hoped. The claim is that you don’t need to use any finish agents with it, but I think that you still should based on the results of my three beers.

Response from MoreFlavor
We're happy to hear you have a gluten allergic friend willing to try, with success. Folks with food allergies should still proceed with caution. Thanks for the review!

Good product
I have family that are gluten intolerant and I use this regularly to reduce the gluten in my beer. So far no one has had any issues after drinking my beer.

Does not change any about the taste. It helps to reduce chill haze but does not clarify a cloudy beer. You will need to fine post fermentation with something else.

Gluten Free Barley Beer
This product is GREAT. In addition to helping clarify the brew, it virtually eliminates gluten proteins. This means my daughter who has Celiac disorder and other gluten sensitive folks can safely drink my brews. I use it in everything I brew.

Amazing and can help drop out the Gluten for my GF wife.
This product is great and I have been using it for years. My wife who gets sick from Gluten can now drink my beers and not have issues because this stuff drops enough out of the beer. Even another friend who has narcolepsy and has episodes from gluten had the guts to try my beer and she had no issues. The other benefit is that it also clarifies my beer and is super easy to use. Just dump it in the primary fermenter. That's it! I talked about this on the Brewing Network when I stopped in for a show.
