Embodiment 1

[0038] 1. Ingredients scheme: main and auxiliary material ratio (weight ratio): 60:40, 60% malt, 40% starch, 60% Australian malt and 40% domestic malt.

[0039] 2. Brewing process:

[0040] like figure 1 As shown, the brewing process of the present invention is divided into three steps, namely a saccharification step, a fermentation step and a filtration step.

[0041] 1) Saccharification step:

[0042] Put 5700KG of malt into the saccharification pot after being pulverized by a dry grinder and keep it at 48°C for 50 minutes for saccharification. Carry out heat preservation saccharification at 72°C. When the iodine reaction is complete, raise the temperature of the mash pot to 78°C. Use a filter press to filter the mash pot wort to the boiling pot. Use a temperature of 102°C to raise the pressure by 150mpa and lower the pressure by 50mpa for 6 times. The total time of stripping is 63 minutes. Low-pressure dynamic boiling, after boiling, pour it into the whirling tank for 25...

Abstract

The invention discloses a method for brewing beer with high concentration wort. The method comprises the steps of saccharification, fermentation and filtration, wherein in the fermentation step, sterile air is used to fill oxygen; and the cooling speed of wort is controlled, the temperature of wort is reduced from 98 DEG C to 8 DEG C, and the cooling time of wort is 50-60 minutes. By adopting themethod of the invention, the problem of high concentration wort that the oxygen-filling amount of wort is easy to be insufficient can be solved, and the normal dissolved oxygen content of high concentration wort can be realized.

Description

technical field [0001] The invention relates to a beer brewing method, in particular to a high-strength beer brewing method. Background technique [0002] At present, domestic beer high-concentration brewed wort exceeds 16 degrees. The general production process is: produce 14-15 degrees wort in the saccharification process, add some syrup or sucrose during the boiling process to increase the concentration to 16 degrees. This method is costly. Due to the characteristics of syrup production, the quality of beer fluctuates and tastes vary. [0003] There are generally two ways to produce high-concentration wort, one is to increase the amount of feeding, and the other is to add sucrose or syrup. In the first method, the amount of feed increases, which requires higher equipment, which increases the load on the equipment, and increases the viscosity of saccharification and gelatinized mash during production. If it is too high, the filtration speed will be slowed down and the re...
