Embodiment 1

[0033] Example 1 Microwave combined with water bath method to pretreat tea leaves to prepare tea beer

[0034] (1) Malt crushing: weigh the barley malt, crush it and sieve it.

[0035] (2) Saccharification: After the malt is crushed, put it in the mash pot, inject pure tap water into the barley malt crushed in step (1) at the ratio of material to water 1:3.5, and put it at 52°C for saccharification after the liquefaction is complete Saccharify in the instrument for 30 minutes, then saccharify at 63°C for 30 minutes, and then saccharify at 72°C until the saccharification reaction is complete as detected by iodine solution, and finally keep at 78°C for 10 minutes to terminate the reaction.

[0036] (3) Wash the grains: filter the mash obtained in step (2), wash the grains at a temperature of 78° C., wash the grains three times, and make the wort concentration at 11±1°P at the end of the washing.

[0037] (4) Wort boiling and hop addition: the total boiling time is 60 minutes, 0...

Embodiment 2

[0043] Example 2 Microwave combined with water bath method to pretreat tea leaves to prepare tea beer

[0044] The specific implementation method is the same as in Example 1, the difference is that step (6) adopts microwave combined with water bath method (pure juice fermentation) to carry out pretreatment to Laoshan green tea. In step (7), the tea water treated and filtered by microwave combined with water bath method is added to the cooled wort in an amount of 1:25 (v:v).

Embodiment 3

[0045] Embodiment 3 boiling method pretreatment tealeaves prepares tea beer

[0046] The specific embodiment is the same as Example 1, the difference is that step (6) adopts boiling method to carry out pretreatment to Laoshan green tea. Boiling method: the ratio of material to water is 1:20, boil for 10 minutes; step (7) add the boiled and filtered tea water to the cooled wort, the addition amount is 1:25 (v:v).

Abstract

The invention discloses tea beer with high antioxidant activity and a preparation method thereof, and belongs to the technical field of wine brewing. Laoshan green tea is used as a raw material, the tea is treated by microwave and water bath methods and fermented with residues, the tea is added in the cooling process of wort, and the following yeast is used for fermentation. The brewed tea beer has strong antioxidant ability, unique tea aroma, mellow taste and lasting foam. The method is simple and easy to operate, the prepared beer increases the flavor and nutrients of the tea on the basis ofmaintaining the flavor of the original whole malt beer, the beer is rich in polyphenols, and the antioxidant activity is significantly improved.

Description
