Wine aeration – is it necessary and how to aerate wine?

Posted on November 9, 2023 by Chris Larkin

Aerating, or exposing wine to air, is something you can do before serving as it can enhance a wine’s flavours and aromas, making it more enjoyable to drink.

Red wine is a popular choice for aeration, often described as “opening up” after exposure to air. However, wine aeration isn’t necessary for all red wine – here’s our guide to the benefits and drawbacks of aerating wine.

What is wine aeration?

Aerating wine simply means exposing the wine to air – often described as letting it ‘breathe’ – before drinking it.

This can be done by decanting, swirling the wine in the glass or using a specialised aerator tool. Exposure to oxygen in the air can help soften a wine’s flavours, enhance its aromas and make it more enjoyable to taste.

Which wines need aerating?

While not all wine needs to be aerated – young, full-bodied red wines with lots of tannins generally benefit most from aeration – some red wines that are described as ‘tight’ or ‘closed’ when a bottle is first opened should be aerated. This is because the wine’s tannins can be quite noticeable when first poured, giving a slight bitterness or dryness.

Aeration goes some way to softening these tannins, making the wine taste smoother and more balanced. It can also help to release the wine’s full range of aromas and flavours. Red wines such as Cabernet Sauvignon, Syrah/Shiraz, Nebbiolo, Barbera, Bordeaux, Merlot and Malbec can benefit from an hour in a decanter.

There’s no need to aerate many lighter-bodied reds, such as Beaujolais or a fruity Pinot Noir, as they are meant to be enjoyed from the first pour.

White wines typically don’t need aerating, though there are exceptions. A few complex, full-bodied whites from Bordeaux, Alsace, Burgundy, and other full-bodied, oak-aged Chardonnays can benefit from aeration.

How do you aerate wine?

Opening a bottle and letting the wine sit uncorked or uncapped isn’t enough for wine aeration.

A wine bottle’s narrow neck doesn’t allow enough contact with the air to improve the taste.

The good news is that there are several easy ways to add aeration to your wine-drinking routine:

  • Aerator – If you want to get serious about wine aeration, consider splashing out on a wine aerator. This attaches to the top of a wine bottle or is inserted into the glass before pouring. It creates tiny bubbles in the wine as it’s poured, helping to expose the wine to oxygen.

  • Decanting – This means pouring wine into a separate container, such as a decanter or glass jug, before serving, helping expose the wine to air.

  • Funnels and filters – Wine funnels and filters serve the same purpose as aerators but work slightly differently. A wine funnel helps push the wine against the decanter’s side as it’s poured, letting more air interact with the wine through a bigger surface area. Look for funnels with built-in filters, which can help remove sediment and aid aeration.

  • Swirling – Simply swirling your wine in the glass can help encourage exposure to the air. A good bet is gently swirling the glass for several seconds before sipping.

Benefits of aerating wine

  • Improved flavour – Aeration can help enhance the wine’s overall flavour.

  • Enhanced aromas – Aeration can also help fully release a wine’s aromas.

  • Better texture – Aeration can improve the texture of red wine by softening the tannins and creating a smoother texture. This can make the wine feel more velvety and luxurious in the mouth.

Drawbacks of aerating wine

  • Over-aeration – It is possible to overdo aeration. If a wine is aerated for too long or too aggressively, it can lose some fruitiness and become flat or dull.

  • Unnecessary for simple wines – Some wine experts argue that aeration is unnecessary for everyday, young red wines because of their lack of complexity. They believe that these wines should be enjoyed immediately after opening without aeration.

  • Personal preference – Whether you aerate a wine or not is a matter of personal preference. Some people enjoy the enhanced flavours and aromas of aeration, while others prefer the taste of red wine straight out of the bottle.

How long do you aerate wine for?

The length of time to aerate depends on the type and age of the red wine, and there are a few things worth knowing that can influence whether you go short or long on the aeration:

  • Young, tannic red wines – These wines can benefit from a few hours of aeration before drinking. Decant the wine into a decanter a couple of hours before serving to open up the wine as much as possible.

  • Older, delicate red wines – These wines can be more sensitive to oxygen and may only need to be aerated for a few minutes before serving. Too much exposure to air can cause the wines to lose their characteristic flavours and aromas.

Your personal preferences play a role, too. It’s important to remember that the wine aeration time can vary depending on personal tastes.

Some prefer their wine to be more heavily aerated, while others prefer something more subtle. It’s also worth considering the specific characteristics of your wine and adjusting the aeration time accordingly. Try experimenting with different aeration times and methods to find what works best for your choice.

How to choose the best wine aerator

Several types of red wine aerators are available, but most work by creating tiny bubbles in the wine as it’s poured, mixing air into the wine. Wine aerators use three methods: waterfall, vortex or aeration chamber.

Each type has a different way of introducing air to the wine, resulting in a unique effect on the wine’s flavour and aroma.

  • A waterfall aerator has a simple design that works by pouring the wine through a funnel, then passing it through a series of narrow slits where the wine is exposed to the air.

  • A vortex aerator has a more complex design that swirls the wine as it passes through. This swirling motion helps to mix the wine with air more thoroughly, resulting in more intense and complex flavours.

  • At the top end are models that use an aeration chamber to introduce air to the wine. Wine is poured into the top of the device, and as it flows down into the chamber, it is exposed to air. The wine then passes through a narrow spout, which helps to release any remaining air bubbles and further enhances the wine’s flavour and aroma.

Waterfall aerators are the simplest and most affordable option, while vortex and aeration chamber aerators are more complex and tend to be more expensive.

If you’re choosing a wine aerator (they make an ideal gift for the wine lover in your life), buy one that will bring out the best in your wine. Look for:

  • Design and functionality – Choose a design that is easy to use and functional. The aerator should fit securely on the bottle with no leaks or splashes.

  • Material – Select a device made from high-quality materials, such as stainless steel or glass.

  • Aeration Process – Each method – waterfall, vortex or aeration chamber – has a unique effect on the wine, so it’s essential to consider which one you prefer.

  • Cleaning and maintenance – Aerators need to be regularly cleaned and looked after, so opt for a device that is easy to clean and has clear maintenance instructions.

Using a wine aerator

Using a wine aerator is easy. Connect it to the top of the wine bottle or insert it into the wine glass, depending on the model you’ve selected, and pour the wine through it. An aerator can be used with any serving of wine, from a single glass to an entire bottle.

Make sure you clean the aerator between uses and ensure it is thoroughly dried before using – you don’t contaminate the wine flavour or risk diluting the wine with water.
