Abstract

In a clarification method for a beverage liquid, in particular for producing beer, the beverage liquid, after it passes through a fermentation stage, is subjected to a clarification which serves for removing active haze components from the beverage liquid, and fed to a maturation vessel in which the beverage liquid is stored for a maturation time. In a further method step, the beverage liquid is charged with at least one pectin-containing clarification agent for increasing a filtration performance. In this case it is provided that the pectin-containing clarification agent is introduced into the beverage liquid on the path from the fermentation stage to the maturation vessel and the pectin present therein, before the feed to the maturation vessel, is at least for the most part removed again from the beverage liquid.
