The preparation method of the raspberry
wine comprises the following steps: S1, pretreating raw materials: cleaning raspberries and litchis, freezing for later use, unfreezing before crushing, and mixing and pulping; washing
red rice, cooking, and cooling for later use; s2, saccharifying: adding sweet distiller's
yeast and Maotai-
flavor yeast into the
red rice, adding
purified water, uniformly stirring, and fermenting to obtain a saccharified product; s3, performing enzymolysis: adding
pectinase into the mixed fruit pulp of the raspberries and the litchis, and performing extraction to obtain enzymolysis fruit pulp; s4, main
fermentation: preparing a suspension from active dry
yeast and
distilled water, activating in a constant-temperature water bath, and adding the activated yeast liquid into a mixture of the saccharification product and the enzymolysis fruit pulp for low-temperature
fermentation; s5, separation and post-
fermentation: after the main fermentation is completed, separating sake from fruit paste and yeast, and performing post-low-temperature fermentation on the sake; and S6,
ageing and filtering:
ageing the
wine liquid after the secondary fermentation, naturally clarifying, filtering, and taking supernate, so as to obtain the raspberry
wine. The invention solves the problems of
nutrition loss, single
flavor and unstable quality of the existing raspberry wine.
