What is the purpose of swirling a glass of wine?

• A. To chill the wine
• B. To clear the glass
• C. To volatize the esters, releasing aroma & flavor elements in the wine
• D. To aerate the wine for faster oxidation

Answer: (C)

Swirling a glass wakes up the wine’s aromas by moving the liquid and increasing its contact with air. This agitation lowers the pressure around volatile aroma compounds, like esters, so they evaporate more readily into the headspace. When you sniff, you’re pulling those evaporated aromas into your nose, which makes the wine’s bouquet—and the perceived flavors on the palate—more expressive. It isn’t about chilling the wine, and while some oxygen exchange happens, the main point is releasing aroma and flavor elements rather than speeding oxidation.
