10 kg of grapes, 2 kg of rock sugar.
10 kg grapes need to put 2 kg of rock sugar. In the process of brewing wine, the ratio of grape to sugar is 5: 1. According to this ratio, 10 kg of grapes can put 2 kg of sugar, and the sweetness of the brewed wine is moderate.
Grapes should be mainly purplish red, full and mature, and free from diseases. After that, they should be disinfected and cleaned in salt water. After cleaning, drain the water on the surface of the grapes. Wear gloves to crush the grapes and put them in a wide-mouth glass bottle. The container needs to reserve 1/3 space to facilitate grape fermentation, and the bottle mouth should not be tightened to avoid explosion.
Brewed wine needs to be kept in a cool and dark environment. After three days, the bottle needs to be tightened. After about a week, the grape pomace can be removed with a filter, and the remaining wine can be stored in a new container.
