White Labs WLN4000 Clarity Ferm (10 ml)
White Labs WLN4000 Clarity Ferm (10 ml)
1 White Labs WLN4000 Clarity-Ferm 10 ml Vial -- A highly specific "endo-protease" to prevent chill haze in your homebrew.

From White Labs:

"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 10 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.

The TTB has issued interim labeling guidelines for beers made with gluten containing grains, and it states:

"TTB will allow use of the statement 'Processed or Treated or Crafted to remove gluten,' together with a qualifying statement to inform consumers that: (1) the product was made from a grain that contains gluten; (2) there is currently no valid test to verify the gluten content of fermented products; and (3) the finished product may contain gluten."

White Labs WLN4000 Clarity Ferm (10 ml)

  • Clarity Ferm can be used with any type of malt or other raw materials.
  • Add at the beginning of fermentation, after the wort has cooled.
  • Entire content per 5 - 7 gallons of wort.
  • Recommended Storage Temperature 68 - 78F

  • Clarity Ferm will increase the colloidal stability in beer by reducing chill haze.
  • Produces gluten reduced beers in beers made from barley and wheat.

During cold storage, chill haze results in the precipitation of complexed polyphenols in beer. The haze develops over time, which initially, can be reversed when increasing the temperature. Eventually chill haze can become permanent.

Clarity-Ferm prevents the precipitation of proteins and polyphenols by hydrolyzing the sensitive (haze-active) polypeptides in the region where the hydrogen bonding occurs. This ensures that no other beer parameters are affected by the specificity of the enzymes.

Simply add Clarity-Ferm when pitching yeast and it will do it's work during fermentation. When fermentation is complete, the chill haze has already been addressed.
