Method for brewing wheat beer by using ungerminated wheat for matching with wheat malt

Abstract

The invention relates to a method for brewing wheat beer by using ungerminated wheat for matching with wheat malt, which comprises the steps of pasting, mashing, filtration of wheat juice, boiling of the wheat juice, precipitation of the wheat juice, fermentation and filtration of the beer. The pasting process adopts rice which accounts for 30-40% of total weight of dry materials and wheat which accounts for 25-35% as raw materials, and 180-200ppm of high-temperature-resistant amylase, protease pentopan, xylanase and gypsum during the pasting process. The method takes the ungerminated wheat as an auxiliary material for brewing the beer, thereby reducing the production cost. The pentopan and the protease are added during the pasting process, the temperature is rapidly increased to the temperature of inactivating oxidase for carrying out pasting and liquefaction after the transient pentosan and protein stop, thereby overcoming the phenomenon that the wheat is added in a mashing kettle, the oxidase promotes the oxidation of pigment substances because that the process is not processed at high temperature, thereby blackening the wheat juice.

Description

technical field

[0001] The invention belongs to the field of beer brewing, and in particular relates to a method for brewing wheat beer with unmalted wheat and wheat malt. Background technique

[0002] Traditional German wheat beer is a top-fermented beer made by using at least 50% wheat malt and adding commonly used barley malt, with an original wort concentration of at least 11°P. The amount of wheat malt in American wheat beer is 30-50% of the grain, and it is produced by the upper fermentation method or the lower fermentation method, and its original wort concentration is 9-13°P or higher. According to my country's drinking wine classification standard GB / T17204-1998, wheat beer is a kind of beer made from wheat malt as the main raw material and fermented from above or below. Compared with barley and rice, making beer with wheat as raw material has the advantages of cheap raw material price, convenient source of raw material, high yield of raw material and good foam per...
