Embodiment 1

[0050] A kind of preparation method of nobleman muscat botrytis wine, concrete steps are as follows:

[0051] (1) Preparation of nobleman muscat raw materials

[0052] ①Picking: When there is fog at night and the humidity is high in the morning, noble rot bacteria will grow and multiply on the surface of the grape fruit, penetrating through the skin. When the weather is dry and hot at noon, the bacteria can infect the fruit, causing the surface of the grape skin to be covered with small holes. , leading to the volatilization of water in the fruit, the concentration of sugar, organic acid and other components, the peel shrinkage occurs, and the color of the fruit also changes from yellow to orange and then to brown. When the sugar content of the fruit reaches 28°Brix, the titratable acidity reaches 7mg / L. It can be picked, and it needs to be harvested manually multiple times.

[0053] ② Destemming: The grapes that have been sorted by ear are sent to the destemming machine thro...
