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 -7 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.

Can you use clarity firm if you plan to bottle condition your beer ?
rich edson on May 23, 2018

I use Clarity Ferm in all of my beers to lower Gluten, as I have a sensitivity to it. I add it with my yeast when pitching and I almost exclusively bottle condition. I have never had any problems with it.
This CellarScience clearzyme is saying that 1/4 tsp is enough for a 5g batch of beer, but Clarity Ferm says that you need 10ml (which is about 8x this amount). Is this more concentrated or are the recommended dosages off?

I think it makes my beer extra malty
I used this for a year on many batches. All my beers seemed extra malty, but since I had a new system I tried to eliminate all the other issues until I finally settled on this ingredient as the reason for it.

I could be wrong, I've had professionally brewed beers that use clarity ferm and do not taste extra malty, perhaps it is me or my system. I stopped using it.

Takes care of my gluten allergy.
Seems to work for my newly diagnosed dermatitis herpetiformis. Any beer I make from now on will have this in it. Would like more beer to carry the 1 liter size as is much cheaper. The shelf life is about 1 year( when stored refrigerated ) so the 1 liter size is tremendously cheaper and can be bought directly from white labs.

What Chill Haze?
Ever since I started using this my beer is crystal clear. NO chill haze! It ONLY gets rid of chill haze, your beer must be clear at room temp.

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!
