What does letting wine breathe do and is it really necessary?

You’ve probably heard the phrase “let the wine breathe” at some point. But what does it actually do?

What does letting wine breathe do and is it really necessary?

What Does Letting Wine Breathe Mean?

Letting wine breathe, or aerating, is the process of exposing wine to air before drinking it. The idea is that by allowing oxygen to interact with the wine, its aromas are enhanced, and its flavors are softened, making it more enjoyable to drink.

Common methods for letting wine breathe include:

Opening the Bottle: This is the simplest method, but it exposes only a small surface area to air, so it’s less effective.

Using a Decanter: Pouring wine into a decanter increases the surface area exposed to air, allowing more effective aeration.

Swirling in a Glass: Swirling wine in your glass helps release its aromas quickly.

Using a Wine Aerator: This device instantly aerates the wine as you pour it.

What Happens When Wine Breathes?

When wine is exposed to air, several reactions take place that can change its taste and aroma:

1. Oxidation: Oxygen reacts with compounds in the wine, softening tannins (the bitter compounds in red wines) and enhancing flavors. This process can make a young, tannic wine taste smoother and more balanced.

2. Release of Aromas: Exposing wine to air allows volatile compounds to evaporate, releasing the wine’s bouquet. Swirling the wine in a glass can help bring out these aromas, making the wine smell richer and more complex.

3. Softening of Harsh Flavors: Wines that are very young or have been recently bottled can have sharp or “closed” flavors. Letting the wine breathe can help mellow these flavors, making it taste more rounded and integrated.

When Is Letting Wine Breathe Necessary?

Not all wines benefit from breathing. Here’s when it’s helpful:

Young, Tannic Reds (like Cabernet Sauvignon or Syrah): These wines often benefit the most from aeration, which helps soften their tannins and enhance their flavors. Letting them breathe for 30 minutes to an hour is usually sufficient.

Full-Bodied Reds (like Bordeaux or Barolo): These complex wines also benefit from some air exposure, usually about 1 to 2 hours.

Older Wines: Aged wines may need only a brief exposure to air, around 15 to 30 minutes, to release their aromas. However, too much air can cause them to lose their delicate flavors.

Whites and Sparkling Wines: Most do not need to breathe. Their flavors are more delicate, and prolonged exposure to air can cause them to lose their freshness.

How Long Should You Let Wine Breathe?

Here’s a quick guide:

Young Reds: 30 minutes to 1 hour.

Full-Bodied Reds: 1 to 2 hours.

Older Reds: 15 to 30 minutes.

Light Reds and Whites: Usually don’t need breathing time.

Remember, these are just guidelines. Taste the wine periodically to decide when it has reached its best flavor.

Conclusion

Letting wine breathe can enhance its flavor and aroma, especially for young, tannic reds or complex full-bodied wines. However, it’s not always necessary, particularly for whites and sparkling wines. Knowing when and how long to let wine breathe can help you get the most enjoyment from every bottle. Cheers!
