The present invention relates to a process for reducing haze in a beverage comprising adding a protein arginine deiminase and a proline-specific endoprotease during preparation of the beverage. The invention further relates to a wort or beer comprising a protein arginine deiminase and a proline-specific endoprotease.

A device for extracting aroma substances from vegetable aroma carriers into a brewing liquid includes a solids separating device for separating the vegetable aroma carriers from the brewing liquid in flow, the solids of the aroma carriers being held back in the solids separating device. The device comprises a heater for heating the suspension of brewing liquid and aroma carriers to an isomerization temperature at which the -acids contained in the aroma carriers are converted into iso--acids.

The invention relates to a brewing plant for continuously or discontinuously obtaining and treating a wort in the beer brewery or beverage industry; wherein the wort derived based on a surface filtration, is obtained continuously or discontinuously. In a second device the wort obtained as such, is set to a first temperature between 0 and 86 C. after completing of the thermal treatment of the wort; and an enzyme-containing substrate is added by means of an apparatus. Therein, the first apparatus for setting the temperature of the wort to a first temperature is arranged downstream to an apparatus for keeping hot or boiling of the wort. The apparatus is arranged downstream to the first apparatus for setting the temperature of the wort to the first temperature. Moreover, a corresponding method and corresponding uses are suggested.
