The invention relates to the field of
wine brewing, and provides mulberry
wine and a
brewing method thereof, an
earthworm breeding by-product and a preparation method thereof. The mulberry
wine brewing method comprises the following steps: crushing mulberry raw materials, adding
pectinase, uniformly mixing the crushed mulberry raw materials and the
pectinase and conducting
hydrolysis so as to obtain juice, and adding
sugar until a
sugar content of the juice is 24%; adding
sugar liquid activating distiller's
yeast, and implementing fermenting so as to obtain mulberry
vinasse; pumping out clearliquid from the bottom layer of the mulberry
vinasse, so as to obtain a mulberry wine body of a first
alcohol degree; distilling dry
vinasse which is obtained after the
clear liquid is pumped out, soas to obtain waste vinasse and a mulberry wine base of a second
alcohol degree; and blending the mulberry wine body and the mulberry wine base, so that mulberry wine of a third
alcohol degree is obtained. With the application of the brewing method, a health-care effect of the mulberry wine is improved; and meanwhile, the purity and taste of the mulberry wine are improved. In addition, as for the
earthworm breeding by-product and the preparation method thereof, earthworms are bred and the by-product is processed by virtue of residual waste vinasse obtained from the mulberry wine brewing method,so that the reasonable utilization of the waste vinasse is achieved; and resource is saved and environmental
pollution is prevented.
