If you want to dry grapes, you need to put them in a dry tray and expose them to the sun for about 65,438+00 days. When a part of the surface is dry, you can turn them all over and put them on the surface to continue drying until two-thirds of the fruits are dry. When there is no grape juice oozing out by hand, you can fold the drying tray and dry it in the shade for a week. On sunny days, the total drying time is about 20 ~ 25 days. After the grapes are washed, they can be dried naturally or blown by a fan to control the water faster. A small amount of clean water is not a big problem. Do not touch the fermented raw water.

It is best to control the water content of grapes used for homemade wine after washing. This kind of drying is not that there is no water on the grape skin, but that it is enough to pick grapes without dripping water. It is difficult without water, but there is too much raw water, which contains a lot of miscellaneous bacteria, which will pollute raw materials and affect the development of fermentation to normal alcohol production. Adding some salt in the early stage of fermentation can solve it.
