1, prepare 2500 grams of rotten wild grapes.
2, the whole bunch of grapes should be washed, and the water should be controlled. It is necessary to control the water in multiple leaky pots. The water is not easy to control, and it takes about 3-4 hours, and it is best to control it for a long time.
3. After controlling the moisture, pick the grapes one by one and crush them by hand. The more crushed the grapes, the better, so that the wine yield is high.
4. Take a large bottle, a layer of grapes and a layer of rock sugar and put them in a glass bottle.
5, don't put it too full, avoid the grape juice overflowing after fermentation, and deflate it every 2-3 days in the middle. After 20 or 30 days, if you see clear liquid and deposited grape residue in the bottle, you can filter it with clean gauze and then put it into a glass bottle for storage.
Extended data
Wild Vitis amurensis has small fruit, thick skin, thick pigment, low sugar content, high acidity and high tannin content. Like wild Ganoderma lucidum and ginseng, it is very rich in nutrients. Taking Vitis amurensis growing in Changbai Mountain as an example, because it grows in the special ecological environment of deep mountains and old forests, it provides unique conditions for the accumulation of intrinsic nutritional functional substances of Vitis amurensis and the formation of wild tastes.
Create that unique quality of wild wild wild grape. The total content of resveratrol in the original wine of Vitis amurensis is 5. 86mg/L, while that in the original wine of Cabernet Sauvignon is 2 .52mg/L, the former is more than twice as much as the latter.
The content of trace elements in the original wine of Vitis amurensis is1.5-2 times higher than that in the original wine of Cabernet Sauvignon, and the content of flavonoids in the original wine of Vitis amurensis 1435mg/L is three times higher than that in the original wine of Cabernet Sauvignon, and the content of anthocyanins in the original wine of Vitis amurensis more than double that in the original wine of Cabernet Sauvignon.
Vitis amurensis is a real green food without chemical fertilizer and only sprayed with pesticides. For example, Tongtian Mountain wine produced by Tongtian Liquor Industry has passed the Grade A standard of green food in China.
