WLN4000 White Labs Clarity Ferm / Brewers Clarex
Clarity Ferm, from White Labs, is an enzyme that breaks down proteins. It is used to prevent chill haze and to produce reduced levels of gluten in beers made from barley and wheat. This is a single vial of White Labs Clarity Ferm.
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.
CLARITY FERM/BREWERS CLAREX HAS BEEN DEVELOPED FOR TWO BREWING PURPOSES
1) To increase the collodial 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 ever 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.
