Preparation materials: distiller's grains: appropriate amount, wooden barrel: one, large bowl: one, aluminum pot: one bite, towel: appropriate amount, water: appropriate amount.

1. First, prepare a clean and waterless wooden barrel, and then pour a proper amount of distiller's grains to flatten it.

2. After the distiller's grains are discharged, put them into a clean, waterless and oil-free bowl.

3. Put the barrel containing distiller's grains into the pot, and then surround the mouth of the barrel with a towel.

4. Put a clean and waterless aluminum pot on the towel, and pay attention to make the inside of the barrel airtight, so as not to leak.

5. Pour a proper amount of clean water into the aluminum pot, then bring it to a boil. Change the water when it is a little hot.

6. After changing the water, burn it until it is hot again, and then take out the big bowl in the wooden bucket, so that the liquor is ready.
