CLARITY-FERM is used to increase the collodial stability of beer by reducing chill haze. It is also used for producing gluten reduced beers in beers made from barley and wheat. An easy way to eliminate chill haze in your finished beer or to produce gluten reduced beer is to add one vial of Clarity Ferm to your fermenter prior to the onset of fermentation. Use 1 vial per 23 litre batch. Does not alter beer flavor or aroma. Has no effect on head retention.
