After the wine is directly put into the refrigerator for a period of time, the temperature of the whole cup/bottle of wine becomes the same low; When a proper amount of ice cubes are put into the glass, the temperature of the wine around the ice cubes is lower, and the farther away from the ice cubes, the higher the temperature of the wine, which means that the temperature of the whole glass of wine is uneven.

Moreover, the taste is better, and the glass with ice can meet the requirements of different people on the temperature of the wine.
