DARACLAR® 920 is used for the selective adsorption of haze-forming proteins from beer. DARACLAR® 920 is added either together with the filter aid or by a separate dosing system to the beer during the filtration stage. The dosage used depends on the desired stability of the beer but lies, in general, from 40-120 g/hl. DARACLAR® 920 is recommended if fast filtration speed is required. DARACLAR® 920 complies completely with the German Beer Purity Law (Certificate of Compliance issued by Prof. L. Narziß of Weihenstephan). DARACLAR® 920 is free from beer damaging organisms.
