If you want to have as much juice as supermarket juice, you can add a certain proportion of water (cold boiled water or pure water) after 1.2 days, and then ferment. If the temperature is enough, it can be completely fermented into rice wine within 10 days.
Water cement ratio 1: 1.3
If you want to drink pure water, you can let it ferment with little or no water.
The degree of completion is about 10 degree. Personally, I like to add some medlar when adding distiller's yeast, and I can also beautify and tonify the kidney.
