Do not add water in the middle, adding water will affect the fermentation process, destroy the taste and taste of the wine, which is not conducive to preservation. When making wine, add enough water at one time.

Extended data:

1, use a rice cooker to cook glutinous rice (ordinary rice is also ok), and the water is less than usual. Cook the rice well, but the grains are hard.

2. After it is completely cooled, put the glutinous rice into a basket, rinse it under the faucet and wash away the sticky things on the rice grains. (This step can be omitted if rice is selected.)

3. Put the glutinous rice into the container. Sprinkle some wine and medicine on each layer of rice. Sprinkle wine medicine and a little warm water on the top. (Or mix distiller's yeast with warm water, cover with rice and mix well.)

4. Compacte the glutinous rice by hand, and drill a hole in the middle of the rice so that the glutinous rice wine can come out.

5. Put the lid on the container into the oven, turn on the light of the oven, and you can smell the wine in a few hours. After 24 hours, it is enough to see glutinous rice floating in wine. (If you are not in a hurry to eat, you don't need an oven. Put it next to the heater in winter, and it will take about 3-4 days. Room temperature is enough in summer.)
