For 20 liters of wine:
If you are sure that the grapes are clean, do not wash them: so wine yeast will remain on the berries. If you are not sure, it is better to rinse or wipe with a wet towel.
Mash the grapes with your hands in an enameled bowl to make the juice stand out. Then do the syrup. Pour water into a saucepan, pour sugar and put it on fire. Do not bring it to a boil, just wait for the sugar to dissolve.
Transfer the berry mixture into a glass bottle, pour the syrup, cover with a lid and put it in a warm place for 21 days. If the room temperature is above 20 ° C, two weeks will be enough.
Stir the mixture with a wooden spoon every morning and evening. If you do not interfere, the pulp (the remains of berries) will sour and spoil the future wine.
After 21 days, strain the wine and leave it in a cool place for a week. This is necessary for the yeast to settle.
In a week you will see a whitish sediment on the bottom. Using a hose or funnel, pour the wine into bottles or cans without touching the sediment.
Then put the wine in a dark, cool place for 6-12 months. The longer the wine stays, the richer its taste will be.
