White Labs Clarity Ferm

White Labs Clarity Ferm (WLE4000) is an easy-to-use enzyme that helps prevent chill haze and reduce gluten levels in beers brewed with barley or wheat. When added at yeast pitch, it breaks down haze-forming proteins during fermentation, producing clearer, more stable beer without changing flavor, aroma, or head retention. It is widely used in homebrewing and small-batch production for reliable clarity improvement.

This enzyme offers two key advantages: it eliminates chill haze that can appear after cold storage and reduces gluten to below 20 ppm in most recipes, making many beers more accessible without altering the brewing process. Because it works during active fermentation, it integrates seamlessly into standard workflows and requires no additional steps after dosing.

Each 10 mL vial treats a 5-gallon batch, with a 20 mL dose recommended when using grists containing more than 20 percent wheat. The formulation remains stable for up to twelve months when refrigerated, ensuring dependable performance from batch to batch. Although Clarity Ferm reduces gluten significantly, gluten-sensitive brewers should evaluate results carefully, as brewing systems and ingredients can influence final levels.

White Labs produces Clarity Ferm using established, quality-controlled enzyme manufacturing methods, making it a trusted option for brewers seeking clearer beer and improved stability without affecting style or character.
