Embodiment Construction

[0012] Select the wild mountain grape varieties produced in the Changbai Mountain area. The harvesting method is to delay the harvesting period. The mountain grapes are frosted on the branches and air-dried for 8 days, and the sugar content is measured to be above 32 Brix. The temperature during harvesting is -10°C and harvested at night. Juicing is to remove the stems, deicing debris, crush and squeeze the harvested mountain grapes at a temperature below 7°C to keep the ice crystals in the grapes from melting and breaking, and add 80ppmSO immediately after juicing 2 . The fermentation temperature is controlled at 28°C, and the yeast carried on the grape skin is fermented, and the fermentation period is 15 days. Surveying its sugar content is 18Brix, and when the alcohol content is 10% (v / v), stop fermentation, and carry out skin dregs separation. Use heat exchange settings to cool down, quickly drop the fermented juice below 12°C, and add 170ppm SO in the fermented juice 2...
