The manufacturing method is as follows:
1. Wash the screened glutinous rice with water, steam it in a pot for about 1 hour, and take it out when it is cooked.
2. Then pour the steamed rice into a basin of warm water for scrubbing to prevent sticky rice from sticking to each other, and then pick it up and drain it.
3. When the temperature drops to about 40 degrees Celsius, grind a certain amount of sweet wine koji, and pour 80% of sweet wine koji into rice and mix well.
4. Put it in a pot or jar, and then sprinkle the remaining 20% sweet wine koji evenly on it. Take warm water at 35 degrees Celsius, slowly pour it into the pot, cover it and put it in into the pit or pot, and keep the temperature at 30 degrees Celsius for about two days.
