Embodiment 1
[0032] A brewing process of cold-resistant wine grape de-alcoholized wine, comprising the following steps:
[0033] S1: Raw material processing: select mature and healthy cold-resistant wine grapes, which require loose and strong fruit stems, uniform fruit size, dark purple color, and thick fruit powder; destem the above-mentioned cold-resistant wine grapes , After crushing, a mixture of grape skins and juice is obtained;
[0034] S2: Canning: fill the bottom of the tank with CO in advance before filling 2 , add CO to the surface of the mixture of grape skins and juice after canning 2 Gas, Baozheng grape skin juice directly contacts CO when it is put into the tank 2 Gas, the mixture obtained in S1 is filled into cans, and after the canning is completed, CO is added to the surface of grape skins and juice 2 Gas, to ensure that the surface of the grapes is above 7cm of CO 2 under the gas shield;
[0035] S3: Fermentation: immerse the mixture of grape skin and juice at 10°C ...
