Swirling

When swirling, the glass is moved in small circles so that the drink runs along the glass wall. The surface area increases, volatile aroma compounds evaporate more easily, and the scent becomes more strongly perceptible.

It is usual with wine and also with spirits. It should be done calmly and with a glass that is not filled too high so that nothing is spilled. With sparkling wine and beer it is avoided because carbonation would escape. The streaks that run down the glass, sometimes called legs or tears, give only rough hints about alcohol and sugar.
