White Labs Clarity Ferm – 10 mL

White Labs Clarity Ferm is a highly specific brewing enzyme designed to reduce chill haze and improve finished beer clarity. Added at the beginning of fermentation, Clarity Ferm breaks down haze-active proteins that can combine with polyphenols and create haze when beer is chilled. It can also significantly reduce gluten levels in beers brewed with barley and wheat.

Clarity & Brewing Performance

Clarity Ferm contains a proline-specific endoprotease that targets haze-forming polypeptides during fermentation. By breaking down these proteins before they can form larger haze-producing complexes, Clarity Ferm helps produce beer that remains bright and clear when chilled.

The enzyme is designed to target the proteins associated with chill haze without negatively affecting important beer characteristics such as color or head retention. It is suitable for use with a wide range of malted barley and other brewing ingredients.

Gluten Reduction

In addition to improving clarity, Clarity Ferm can significantly reduce gluten in beers produced with barley and wheat. Properly treated beers can test below 20 ppm gluten. Because the beer is still produced from gluten-containing grains, however, it should be considered gluten-reduced rather than inherently gluten-free.

Use & Applications

• Reduce or eliminate chill haze
• Improve finished beer clarity and stability
• Reduce gluten levels in beers brewed with barley or wheat
• Suitable for ales and lagers
• Can be used with a wide variety of malt bills and beer styles
• Useful for brewers seeking clearer beer without traditional post-fermentation fining treatments

How to Use

Add Clarity Ferm to cooled wort at the beginning of fermentation. Add the enzyme during knockout or immediately before pitching yeast so it can mix thoroughly throughout the wort.

Dosage requirements can vary depending on batch size, original gravity, malt composition, and whether the primary goal is chill haze reduction or gluten reduction. Follow the manufacturer dosage guidance for your batch size and intended application.

Brew Tips

• Add Clarity Ferm to cooled wort before or at the time yeast is pitched.
• Ensure the enzyme is thoroughly mixed into the wort for even treatment.
• Follow White Labs dosage guidance rather than estimating the required amount.
• Dosage may vary depending on grain composition, gravity, batch size, and intended application.
• For gluten reduction, remember that treated beer is produced from gluten-containing ingredients and should not automatically be described as gluten-free.
• Keep refrigerated at 39-46°F (4-8°C) for extended shelf life.
