Problems solved by technology

[0003] In the prior art, the methods of eating kudzu root are mostly in the forms of brewing, soaking in water, and grinding into powder, etc., but these eating methods are relatively single, the taste is not good, and it is impossible to meet the different needs of various groups of people, especially after using kudzu root for wine making. , the kudzu root taste is too strong and sour, which affects the taste. In addition, the extraction rate and conversion rate of the active ingredients of kudzu root itself are not good, which will also affect the nutritional quality of the finished wine itself.

Embodiment 1

[0028] The preparation method of kudzu root north ice red mountain grape fermented wine is as follows:

[0029] 1) Use a fruit juice press to crush and destem the fully mature Arctic Red Mountain grapes and squeeze the juice to obtain Arctic Red Mountain grape pulp 2L, for subsequent use; and use Aspergillus sweetpotato strains that do not produce toxins to strengthen subculture on PDA medium, Then transfer under aseptic conditions to the Erlenmeyer flask that packs into 500ml pre-sterilized Arctic Red Mountain grape pulp and cultivate and activate to obtain the mold slurry, which is for subsequent use;

[0030] 2) Take another 500ml of Arctic Red Mountain grape pulp, put it in an autoclave and sterilize it at 120°C for 20 minutes, and when the temperature is naturally cooled to 30°C, use a circular inoculation needle to pick out the pulp that is already at room temperature in the ultra-clean workbench. Put the Angel brand active dry yeast strain for 2-3 hours, transfer it int...

Abstract

The invention provides a preparation method of kudzu root / Beibinghong amur grape fermented wine. The method comprises the following steps: (A) crushing Beibinghong amur grapes to obtain a Beibinghong amur grape pulp for later use; culturing an Aspergillus batatae strain in a culture medium, inoculating in a certain amount of the Beibinghong amur grape pulp, and culturing and activating to obtain a mold slurry for later use; (B) inoculating Angle-brand active dry yeast in part of the rest of Beibinghong amur grape pulp, and culturing and activating to obtain a microzyme slurry for later use; and (C) boiling kudzu root, naturally cooling to obtain a kudzu root fermentation substrate, adding the mold slurry, degrading for some time, adding the rest of Beibinghong amur grape pulp and the microzyme slurry, and fermenting for 10-20 days. The kudzu root / Beibinghong amur grape fermented wine prepared by the preparation method has the advantages of high nutritive value, sour and sweet mouthfeel and pleasant fragrance, and adapts to demands of different consumers.

Description

technical field [0001] The invention relates to the field of fermented fermented wine, in particular to a kudzu root and Beibinghongshan grape fermented wine and a preparation method thereof.
