1. Prepare materials: grapes, rock sugar, glass jar.

2. Select grapes: If you want to make delicious wine, purple-red mature grapes are generally the most suitable. Common Kyoho grapes, raisins, and horse milk are all acceptable.

3. Cleaning grapes: This is also particularly important in the production method of wine. Because pesticides and other harmful substances will remain on the skin of the grapes, soak them in light salt water for about 10 minutes, and then rinse them with running water.

4. Dry grapes: Put the grapes into a leaky container and let them dry naturally to prevent the moisture on the grape skin from being brought into the wine, which will affect the taste of the wine.

5. Choose a container: Generally, choose a transparent wide-mouth glass jar, which can be used to observe the fermentation situation. Do not use plastic containers, because plastic containers are likely to interact with the components in alcohol. A chemical reaction that releases substances that are harmful to human health.

6. Put it into the container: After waiting for the grapes to dry naturally, wash your hands and put on gloves, then use a clean container to crush the grapes one by one, then put one layer of grapes and one layer of rock sugar, and so on. Put it into a glass jar and seal it for fermentation. . Note: What needs to be noted in this step is that when filling the bottle, be careful not to fill it too full. It is best to leave one-third of the space in the bottle. Because grapes will expand during the fermentation process, a large amount of gas will be produced. If it is filled too full, the grape juice will overflow and even cause the glass jar to break.

7. Fermentation for half a month: The temperature is high in summer, so the fermentation time is short, about a week. If you want a stronger taste, you can also choose to ferment for about ten days. In autumn, when the temperature is lower, it takes about half a month to ferment.

8. Filter and drink: After the fermentation is completed, you can filter it and drink it. Be careful to separate the grape seeds, grape skins and fermented grape pulp, usually using a filter. Disinfect before use to avoid introducing bacteria into the wine. After filtering is complete, you can drink it directly! .

9. Bottle and store: You can’t finish the grapes brewed at one time, so the excess wine must be bottled and stored. Pay attention to sealing when putting it in the bottle, and then put it in a cool and dry place. , available at any time when drinking.
