Swirling a wine glass.
Swirling the glass and exposing the wine to more air helps oxidize the wine and bring out its aromas.
The greater the surface area of the wine exposed to the air, the more aromatic substances will be released and the greater the sense of aroma.
It is also said to have the effect of reducing the astringency of red wine.
One thing you can't miss when swirling the wine glass is the film of wine that forms on the inside of the glass. This film gives off a slightly fragrant, astringent, and dry aroma of the wine.
Swirling the wine glass around releases the aromatic substances in the liquid to the outside and distributes the wine evenly around the inside of the glass. This allows you to enjoy the delicious aroma of the inside of the glass once the wine has dried.
