Is red wine that clings to the glass a good red wine?

Many people will carefully select when buying red wine, want to choose a red wine that is more to their taste. Whether red wine sticks to the glass is one of the important factors that many people consider when choosing red wine. Red wine legs refer to the traces left on the wall of the glass after the red wine is poured into it, which indicates that the red wine is more mellow and has a higher concentration. So, is the red wine that clings to the glass good wine?

1. If you know a lot about wine, you can judge the quality of a bottle of wine by the phenomenon of wine clinging to the glass. For example, a bottle of Australian Shiraz may smell not only heavier berry aromas, but also peach, apricot and fragrant floral aromas. You may have reason to guess that this wine is a blend of Shiraz and Viognier. In order to further confirm your judgment, you can draw a conclusion by observing its hanging cup situation. If the wine has more obvious legs than other wines and flows slowly, then it is most likely Viognier, a grape variety rich in glycerol.

2. On the contrary, if a bottle of Pinot Noir wine has a strong flavor left in the glass, it is not necessarily a good thing. Because Pinot Noir has a light body and elegant taste, if it leaves obvious residue on the glass, it means that the sugar content, glycerin content or alcohol content may be high, then this wine should be a relatively rough Pinot Noir.

Gently shake the wine glass to allow the wine to form a vortex and circle around in the glass for several times before stopping. This will cause the "red skirt" that was just spinning happily to suddenly stop dancing. The wine flowing down the upper wall of the glass at this time is not the so-called wine hanging on the glass. Instead, what you will see after a while is the protruding circle of residual water marks at the highest point of the "skirt" slowly sliding down the wall of the glass, as if a few lines of tears are slowly flowing. This is called wine hanging on the glass.

3. The degree of wine sticking to the glass directly reflects two issues: one is the viscosity of the red wine, and the other is its surface tension.

The so-called viscosity of wine means that wine contains not only alcohol and water, but also other trace substances such as sugar and glycerol, both of which will directly affect the viscosity of wine. The alcohol content affects the degree of surface tension of the wine. The higher the alcohol content, the faster the wine evaporates, and the greater the surface tension of the wine, and the stronger its adhesion to the wall of the glass. Therefore, the higher the sugar content, glycerol content and alcohol content of a bottle of wine, the better the wine will stick to the glass. In other words, we can see the above three little secrets of this wine at a glance from the wine's wine glass legs.
