Production method: 1, raw material treatment. Choose grapes with large particles, strong color, full maturity and no pests and diseases, wash them with clear water, remove the fruit stalks, put them in a clean aluminum pot, and crush them one by one by hand or with a flat-bottomed tea jar. 2. Preparation of fruit juice: aluminum pot containing raw materials is heated on a fire at a temperature of about 70℃. After 5 minutes, pour the broken pulp in the pot into the gauze covered with four layers, filter it and squeeze it by hand to increase the juice yield. 3. Post-treatment of fruit juice. Add 200-300g white sugar to the prepared grape juice per kilogram, stir well, put it on fire, and sterilize at 80-85℃ for 20 minutes. When sterilizing, put the bottle used to hold grape juice in another pot for sterilization. Sterilize the fruit juice, bottle it while it is hot, tighten the bottle cap, soak it in water at 80℃ for 20 minutes, take it out and naturally cool it.

3. pour the grapes, fill them up, add rock sugar, no need to add water. When the grapes are fermented into water, you can drink grape juice, which is the unique secret of "Diao Brothers". Note: although the grape juice is very good, it is also more than ten degrees. Beware of getting drunk!
