Is the quality of red wine hanging glasses good?

What is the phenomenon of hanging red wine glasses?
If you usually drink, pay attention to it. Before drinking, we will slightly shake the wine glass to make the wine emit more aroma and at the same time, it also plays a role in decanting.
After the wine glass is shaken, the wine in the glass slowly tends to be still. At this time, there is still part of the wine remaining on the wall of the wine glass. Under gravity, it flows down the wall, leaving a trail on the wine glass. The net-like or streak-like marks look a bit oily.
This is the phenomenon of hanging red wine glasses.


In fact, when we use wine glasses to taste wine, almost all red wine will "hang the glass." "Hanging cups" are also divided into "long hanging cups" and "short hanging cups" according to different types.

The so-called "long hanging cup" means that the flow of wine traces is relatively slow, while the "short hanging cup" means that the flow of wine traces is faster. Generally, wines with higher sugar or alcohol content are more viscous and have a thick and thick body. Therefore, a "long hanging cup" is formed.


So, is the quality of wine "hanging glasses" necessarily good? Not necessarily. But the alcohol concentration is definitely higher.
Because the number of red wine hanging glasses is related to two substances, namely alcohol content and sugar content. The most important factor affecting wine hanging glasses is the alcohol content of the wine.
Alcohol has strong adhesiveness. Since the volatilization speed of alcohol is faster than that of water, when the alcohol volatilizes, the surface tension of the water on the inner wall of the wine glass will become higher and higher.
Under the action of surface tension, the wine is pulled into a series of hanging cups and slowly slides under the action of its own weight.

Therefore, the degree of hanging the glass of red wine cannot directly reflect the quality of red wine. "Hanging the glass" is a normal manifestation of wine maturity. It will neither affect the quality of the wine, nor the fruity aroma and taste of the wine. It will not be harmful to the human body.
