Decanting & Breathing

When decanting helps, when it does not, and how oxygen can change young, mature and sedimented wines.

Decanting can separate wine from sediment or give a young wine more contact with air.

Decanting is useful for two different reasons: to separate a wine from sediment, and to expose a wine to oxygen. Those are related but not identical goals.

Decanting for air

Young, structured red wines can sometimes seem closed, tight or dominated by tannin immediately after opening. Pouring the wine into a decanter increases its contact with air and can help aromas emerge and the wine feel more expressive.

There is no universal rule for how long a wine should “breathe.” Some wines open noticeably over thirty minutes; others benefit from several hours. The safest method is to taste as you go.

Decanting for sediment

Older red wines can develop sediment in the bottle. In this case, decanting is less about aeration and more about separating the clear wine from those solids.

Stand the bottle upright in advance if possible, pour slowly, and stop when sediment approaches the neck. Mature wines can also be fragile, so aggressive aeration may cause them to fade rather than improve.

What about white wine?

Some full-bodied or complex white wines can also benefit from air, although decanting whites is less common. The principle is the same: if the wine seems muted, oxygen may help reveal more aroma and texture.

The Decanting & Breathing video on this page demonstrates the basic idea.

What to remember

  • Decant young wine to increase oxygen exposure.
  • Decant older wine primarily to separate sediment.
  • Mature wines can be delicate, so more air is not always better.
  • There is no perfect stopwatch: taste the wine as it evolves.
