Brewing method of tea beer with characteristic substances of Lu'an Guapian tea reserved

Abstract

The invention belonging to the technical field of tea beer provides a brewing method of tea beer with characteristic substances of Lu'an Guapian tea reserved. The brewing method of the tea beer comprises the following steps: performing crushing, performing saccharifying, filtering wort, boiling the wort, and carrying out cyclotron precipitation; performing standing, separating coagulum, cooling wort, inoculating yeast, and performing fermenting; carrying out primary fermentation for 8-10 days at a temperature of 25-38 DEG C, carrying out secondary fermentation for 8-12 hours at a temperature of 4-6 DEG C, simultaneously controlling the blood glucose reducing amplitude, removing part of bottom-layer yeast, keeping the number of yeasts remaining in the wine liquid in the tank to be 4-8 million, then not discharging the yeasts, carrying out cold insulation storage for 1-3 days at a temperature of 3 + / -1 DEG C after the secondary fermentation is finished, and carrying out in-situ secondaryfermentation. And in the in-situ secondary fermentation process, a mixed tea sugar solution is added into a fermentation tank, secondary in-situ fermentation is carried out at 0-3 DEG C, 0.2-0.8 g / Lpullulanase is added after fermenting for 60-85 hours, and fermenting is carried out for 5-9 days to obtain the finished product Lu'an Guapian beer. According to the invention, the content of characteristic substances of the Liuan Guapian tea in the tea beer can be remarkably increased, the tea aroma of the beer is rich, and the market value is extremely high.

Description

technical field [0001] The invention belongs to the technical field of tea beer, and in particular relates to a brewing method of tea beer which retains the characteristic substances of Lu'an Guapian. Background technique [0002] The output of Lu'an Guapian is the largest in Lu'an City, accounting for more than 80% of the total output. Among them, the annual output of Lu'an Guapian in the high mountain area of ​​Lu'an Tea Valley has reached 25,000 tons. Lu'an Guapian contains protein, carbohydrates, amino acids, alkaloids, tea polyphenols and other nutrients. Drinking it regularly can clear the heart, relieve heat, relieve heat, refresh the mind, reduce inflammation, anti-aging, and lower blood fat. It is an ideal tea for summer heat and thirst. drink. However, due to the special picking method of Lu'an Guapian, only fresh single leaves are picked, resulting in a large amount of big-leaf tea being wasted. By using these large-leaf teas as raw materials for deep processing...
