Why do people swirl wine?
Answer: Since most of the enjoyment of wine comes primarily from aromas, swirling the wine will aerate it slightly, potentially releasing more of those aromas. These will rest in the bowl of the glass as you raise it to your nose. For this reason, you do not need to constantly swirl a glass of wine (unless it needs heavy aeration), just enough to release aromas before your first sip.
How exactly does swirling work?
Swirling helps release the hundreds of different aroma compounds found in wine. These compounds are the reason why wine has such an array of aromas. For example, in a rich, powerful California Cabernet, you might find blackberry, cedar and vanilla–all at the same time. These compounds are tiny, so small that they float on evaporating alcohol into our noses; this is what delivers the aromas of wine into the olfactory system. We say aroma because a large part of wine enjoyment is found in our nose’s ability to smell.
If you want to prove the importance of aroma in wine to yourself, just plug your nose. All the aromas of fruit will disappear and the true taste (i.e. sour, bitter, sweet, and salty) and texture of wine will remain in isolation from the aromas.

How does one swirl? and not make a mess everywhere…
The easiest way to start swirling is to place your thumb and forefinger at the base of a stemmed wine glass while it’s siting on the table. Then, draw little circles on the table while gripping the base of the glass.
As you get better, you can try swirling without a table beneath your wine.
Wine Tastes Better in Better Glasses
To swirl wine well, you’ll need room in your glass. It also makes a difference what glass you choose. Find out which type of wine glass is best for you (P.S. They don’t have to be expensive).
