What is the purpose of decanting wine?

• A. Decanting cools the wine quickly to preserve freshness.
• B. Exposing wine to air by pouring into separate vessel to soften tannins, release aromas, and accelerate complexity.
• C. Decanting increases carbonation.
• D. Decanting sterilizes wine.

Answer: (B)

Decanting is about aeration: exposing wine to air in a separate vessel so its aromas and flavors can unfold. Pouring into a wide, clean decanter increases the wine’s surface area and speeds the interaction with oxygen, which helps soften tannins in many red wines, release aromas that may be muted in the bottle, and generally make the wine seem more complex and lively. It can also separate sediment from older wines for a cleaner, clearer pour. This isn’t about cooling to preserve freshness, increasing carbonation, or sterilizing the wine, which is why those options aren’t correct.
