1. Main ingredients: 10,000 grams of black raspberries. Other ingredients: 1,000-1,500 grams of white sugar or fine rock sugar.

2. Take clean fresh fruits picked on a sunny day, wash your hands and squeeze the fresh fruits into pulp.

3. Add white sugar or fine rock sugar according to the ratio of 10 to 1 to 1.5.

4. Clean the glass container containing the pulp with soju. The pulp takes up two-thirds of the bottle to leave space for fermentation.

5. Tightly seal the bottle cap and wait until it ferments naturally, the dregs float to the top, and the wine becomes clear. After opening the bottle and smelling the rich aroma of fruit wine, filter the dregs with three layers of gauze.

6. Separate and sterilize the wine bottles (please wash the bottles if you use 50% alcohol). After storing them for another week, you can drink sweet wine with an alcohol content of about 15%. A sour fruit wine.
