1. After washing the grapes, dry or dry the cold water on the surface of the grapes.

2, into a container that can be sealed, (it is best not to break it easily) don't fill it and then seal it.

3, put it in the sun 1 month or so, (fermentation), open the closed container, be careful when opening it, otherwise the fermented gas will open the lid of the container at once, (at this time, all the juice in the grapes has come out) Filter off the grape skin with clean gauze, add white sugar, and decide how much according to your own taste.

4. Finally, seal the filtered grape juice 1 month.

Method 2:

Materials: grapes, sugar, sealed cans, gauze.

Practice: put grapes and sugar in a jar at a ratio of 3: 1 and crush them by hand. It is best to knead them until they are basically water-like except for the skin and seeds. Seal the jar and put it in a cool and dry place for about 20 days. Finally, filter off the skin and seeds with gauze and you can drink it. (Actually, you can do it without filtering).

Remarks: Don't always touch the oil on cans and food, or it will break. Don't open the jar for 20 days.
