Problems solved by technology

[0003] Grapes need to be processed during brewing, and the grape seeds need to be separated from the pulp, but the grape seeds cannot be damaged. If the grape seeds are damaged and mixed into the pulp, the wine will become astringent and affect the taste.
The existing technology has poor effect on the separation of grape seeds and pulp, and the efficiency is not high

Abstract

The invention discloses tea polyphenol grape wine and a preparation method thereof. The tea polyphenol grape wine is mainly prepared from the following raw materials in parts by weight: 100 to 150 parts of fresh grape, 15 to 20 parts of tea, 30 to 60 parts of maltose, and 100 to 200 parts of water. As the effective component tea polyphenol of tea is added into grape wine, the tea polyphenol grapewine has the efficacies of maintaining beauty and keeping young, oxidation resistance and ageing resistance.

Description

technical field [0001] The invention belongs to the technical field of wine making, and in particular relates to a tea polyphenol wine and a preparation method thereof. Background technique [0002] Grape-flavored grape family woody vines, cylindrical branchlets with longitudinal ribs, glabrous or sparsely pilose, oval leaves, well-developed base branches, spherical or oval fruit, flowering period 4-5 months, fruiting period 8-9 months. Grapes are edible and can also be used to make wine, which is delicious and loved by the public. [0003] Grapes need to be processed during brewing, and the grape seeds need to be separated from the pulp, but the grape seeds cannot be damaged. If the grape seeds are destroyed and mixed with the pulp, the wine will become astringent and affect the taste. The prior art is not effective in separating grape seeds and pulp, and the efficiency is not high. [0004] On the other hand, how to use brewing technology to efficiently extract various ...
