The present invention belongs to the field of
brewing technology, and specifically relates to a green plum sparkling
wine and a preparation method therefor. The preparation method comprises the following steps: first adding a green plum fruit into
wine, introducing
carbon dioxide into the
wine, and sealing the wine; and after sealing, heating and pressurizing same, and then cooling same to
room temperature to obtain a green plum sparkling wine. According to the preparation method of the present invention, by introducing
carbon dioxide and heating under a sealed condition, the
carbon dioxide is incorporated into the green plum fruit to change the density thereof. In a sealed state, there is a certain pressure in the wine body and in the packaging gap, and the
solubility of the carbon dioxide is high under
high pressure. After opening, the space pressure is released, such that the carbon dioxide in the wine body is released outwards to form a large number of small dense bubbles, and an upward floating power is formed to drive the green plum fruit to float upwards and keep floating on the liquid surface of the wine body. The present invention not only retains the
flavor and characteristics of traditional green plum wine, but also improves the freshness preservation effect and the refreshing effect of the green plum sparkling wine by means of carbon dioxide.
