Abstract

The invention discloses a method for brewing turbid white beer. The method comprises the steps of saccharifying, filtering, boiling, fermenting and packaging. In the saccharification step, the protein interregna time can be directly skipped, heating by grading and insulation for a while can be carried out and then the filtering process is performed; in the fermentation step, yeast on 68 obg. German special wheat beer is selected and fermented at 18-20 DEG C, when residual sugar is decreased to 2.5-3.5 DEG P, the pressure is increased to 0.1-0.15MPa, fermentation is fully carried out for 3-5 days under the condition of keeping pressure and temperature, then cooling by grading, wine storage and yeast removal are carried out, the yeast amount in a broth is controlled at 0.2-1 million / mL; and the broth is not required for filtering and diluting, and is packaged to obtain the product. According to the invention, yeast on the wheat beer is used for fermentation, no filtering and diluting is required in the brewing technology, the prepared turbid white beer has the advantages of bitter taste, soft mouthfell, protrude ester fragrance and rich wine body, and the whole method has the advantages of simple and easy operation.

Description

technical field [0001] The invention relates to the technical field of beer brewing, in particular to a brewing method of turbid white beer. Background technique [0002] White beer (or cloudy white beer) is mainly brewed from barley malt and wheat malt, which is fermented by brewer's yeast and lactic acid bacteria. Because white beer is generally drunk in the form of draft beer, it is rich in yeast and lactic acid at the same time, which greatly improves the nutritional value of beer and meets the nutritional requirements of today's consumers. Compared with ordinary beer, the taste is softer and more refreshing. The range of 10°P flavor substances in ordinary beer is generally, acetaldehyde content ≤ 6.5mg / L, total higher alcohol content ≤ 100.0mg / L (including isoamyl alcohol content ≤ 73.0mg / L), alcohol-ester ratio ≤ 4.8; and turbid The most distinctive feature of white beer is that ethyl acetate is 10-15 mg / L higher than ordinary beer, isoamyl acetate is 2-3 mg / L higher ...
