How to make red wine:

1. Buy fresh grapes from the market.

2. Wash the grapes with clean water and drain the water. When washing the grapes, you can add some starch or salt appropriately.

3. Crush the grapes with your hands, then put them into a glass container and add sugar.

4. Seal the glass container and wait for the grapes to slowly ferment.

5. After about half a month, use fine gauze to filter out the impurities in the glass bottle, seal it again, and wait for it to continue fermenting for about a month.

6. The fermented wine is ready to be enjoyed.
