WLN4000 Clarity Ferm/Brewers Clarex


1) To increase the colloidal stability of beer by reducing chill haze.
2) Producing gluten reduced beers in beers made from barley and wheat.

It is available in a variety of packages for every size brewery 


Chill haze in beer results from the precipitation of complexed polyphenols and proteins during cold storage. This haze develops over time and, initially, is reversible (haze disappears when the temperature of the beer increases). Eventually this chill haze can become permanent.

Clarity Ferm will prevent the precipitation of complexed polyphenols and proteins by hydrolyzing the sensitive (haze-active) polypeptides in the region where such hydrogen bonding occurs. The specificity of the enzyme ensures that no other beer parameters are affected.

This easy-to-use enzyme can be used on all types of brewing materials and is a cost effective product to replace silica gel or PVPP. Simply add when pitching yeast, and Clarity Ferm will do its work during fermentation. When fermentation is complete, chill haze has already been addressed.

In addition to eliminating chill haze, Clarity Ferm significantly reduces the gluten content in beers made with barley and wheat. A Clarity-Ferm treated beer made from barley or wheat usually tests below 20 ppm of gluten, the current international standard for gluten free. White Labs offers gluten testing for beers, this test will allow brewers to know the gluten level of the beers it produces, but brewers are not allowed to use this value on their labels until the FDA completes its validation.

*Made with Brewer's Clarex by DSM
