1. Prepare fermented grains. Fermented grains that are not eaten for the time being can be stored or frozen in the refrigerator to avoid the deterioration of fermented grains.

2. Take a clean cloth bag, put the distiller's grains into the cloth bag, tie the mouth of the cloth bag tightly with a rope, and then hang it in a place to let the water in the distiller's grains flow out slowly, while retaining the fragrance in the distiller's grains.

3. When all the water in the mash flows clean, take out the cloth bag and store the remaining mash in a sealed bottle.

4. If you want to make the wine taste more pure, you can filter out the wine, put the filtered wine in a clean container, add some sugar and osmanthus, and then store the container in the refrigerator, which will make the wine more delicious.

The above are the specific steps of sweet wine filtration, I hope it will help you.
