What Is Decanting? A Simple Guide to Decanting Young and Old Wine

Decanting sounds like one of those wine words that belongs in a formal restaurant.

But the basic idea is simple.

Decanting means pouring wine out of the bottle and into another vessel, called a decanter.

That is it.

The reason behind it depends on the wine. Sometimes you decant a young wine to give it oxygen and help it open up. Sometimes you decant an old wine to separate the clear wine from sediment.

In this Chuck Furuya Uncorked tutorial, Ariana Suchia and Chris Ramelb explain what decanting is, why it matters, and how to do it without making the process feel intimidating.

What Is Decanting?

Decanting is the act of transferring wine from its bottle into a decanter.

A decanter is usually a glass vessel with enough room for the wine to spread out and interact with air.

The process can serve two main purposes:

• To aerate young wine and help it open up.
• To separate older wine from sediment before serving.

The same tool can do both jobs, but the technique changes depending on the bottle.

Young wines usually need more air.

Old wines usually need more care.

Why Decant Young Wine?

Young wine can sometimes feel closed when first opened.

It may smell muted, tight, reduced, sharp, or less expressive than expected. The wine is not necessarily bad. It may simply need time and oxygen.

Chris compares it to waking someone up.

Sometimes a young wine needs to stretch out.

When you pour it into a decanter, you expose it to oxygen. That oxygen can help the wine become more expressive.

A young wine may begin to show more:

• aroma;
• fruit;
• texture;
• complexity;
• softness;
• and balance.

This is why people say a wine needs to “breathe.”

Wine Is Alive After Opening

One of the best ideas in the episode is that wine changes once it is opened.

As soon as you pull the cork or open the screw cap, the wine begins interacting with oxygen. From that point, the wine is on a clock.

Chris jokingly describes this as enjoying the wine’s decay. Ariana prefers to think of it as celebrating the wine’s life.

Both ideas point to the same truth:

Wine is not static.

It changes in the bottle, in the decanter, and in the glass.

That is part of what makes wine interesting.

Oxygen: Helpful but Not Always Safe

Oxygen can help wine.

It can wake up aromas, soften edges, and bring the wine into a more expressive place.

But oxygen can also eventually damage wine. Too much time with oxygen can make a wine taste flat, tired, or oxidized.

That is why decanting is not one-size-fits-all.

A young, structured wine may need oxygen.

An old, delicate wine may be hurt by too much oxygen.

The skill is knowing what the wine needs.

Why Decant Old Wine?

Older wines are often decanted for a different reason: sediment.

As wine ages, small particles can form and settle in the bottle. This sediment is not usually dangerous, but it can feel gritty and unpleasant in the mouth.

As Chris says, you want to drink your wine, not eat it.

Decanting older wine lets you pour the clean wine into a decanter while leaving the sediment behind in the bottle.

This is especially useful for aged red wines.

Be Careful with Older Bottles

Older wines can be fragile.

When you decant a young wine, you may want to give it oxygen and energy.

When you decant an old wine, you usually want to move slowly and gently.

Too much oxygen can speed up the wine’s decline. An old wine may have a shorter remaining life once opened, so aggressive decanting can make it fade too quickly.

That is why older bottles require more attention.

The goal is not to shake them awake.

The goal is to protect them while removing sediment.

The Two Main Reasons to Decant

The episode breaks decanting into two simple categories:

• Young wine: decant to add oxygen and help the wine open up.
• Old wine: decant to separate sediment and serve the wine cleanly.

This is the easiest way to remember the difference.

Young wine needs air.

Old wine needs careful handling.

Why Use a Candle or Light Source?

Traditionally, sommeliers use a candle when decanting older bottles.

The candle is not for drama, even though it looks dramatic.

It is used as a light source so the person pouring can see sediment moving through the neck of the bottle.

Ariana explains that you do not want the bottle sitting directly on top of the candle. You are not trying to warm the wine. You are using the light to watch the wine.

Today, you can use something more practical, like a phone flashlight.

The point is visibility.

How to Decant an Older Wine

When decanting an older wine, the process should be slow and controlled.

Use a light source under the neck of the bottle so you can watch the wine carefully.

Basic steps:

• Open the bottle carefully.
• Place a candle or phone light under the bottle neck.
• Hold the bottle steadily.
• Pour slowly into the decanter.
• Keep your eyes on the bottle the entire time.
• Watch for sediment moving toward the neck.
• Stop pouring when the wine becomes cloudy or murky.

The last bit of wine may stay in the bottle with the sediment.

That is normal.

It is better to lose a small amount of wine than to pour grit into everyone’s glass.

Do Not Take Your Eyes Off the Bottle

Ariana emphasizes that when decanting, especially an older wine, you should not take your eyes off the bottle.

Not for a second.

You are watching for sediment.

At first, sediment may look like a faint smoky layer. Then the wine near the neck may start to look murky.

That is your warning sign.

Once you see sediment approaching, stop pouring.

This is the part of decanting that requires focus.

Do Not Touch the Bottle to the Decanter

Another service detail: try not to let the bottle touch the decanter.

It is a small thing, but it matters in professional service.

No one wants unnecessary clinking sounds, and the movement should look clean and controlled.

At home, this is less formal, but the habit is still useful.

A steady hand makes the whole process smoother.

Why Bordeaux Bottles Have Shoulders

Ariana mentions that some people say the classic Bordeaux bottle shape, with high shoulders, was designed to help catch sediment.

Whether or not that is the only reason for the shape, the idea makes sense. The shoulders can help slow sediment as wine is poured.

This matters most with older red wines that have thrown sediment over time.

The bottle shape, the light source, and the slow pour all work together to help keep sediment out of the decanter.

How to Decant a Young Wine

Young wine is different.

If there is no sediment and the goal is oxygen, you do not have to be as delicate.

For a young wine, you can pour more directly into the decanter. You can give it a swirl. In some cases, you can even pour it between two decanters to increase aeration.

The goal is to expose the wine to air.

Basic steps:

• Open the bottle.
• Pour the wine into the decanter.
• Give it a gentle swirl.
• Let it sit and open.
• Taste it over time to see how it changes.

For a young wine, the decanter is like a stretching room.

It gives the wine space.

When Should You Decant?

There is no universal answer.

Chris points out that if you ask ten different wine people whether to decant a certain bottle, you may get ten different opinions.

That is because wine is alive, and every bottle is different.

Still, some wines are more likely to benefit from decanting.

You may want to decant:

• young structured red wines;
• young wines that smell closed or tight;
• wines with strong tannin;
• wines that feel reduced or muted;
• older red wines with sediment;
• serious wines that need time to show themselves;
• and wines you want to observe as they change.

You may not need to decant:

• simple everyday whites;
• very delicate old wines that may fade quickly;
• sparkling wine;
• light fresh wines meant to be drunk immediately;
• or bottles that already smell open and expressive.

The best rule is to taste first when possible.

What Happens If You Decant Too Much?

If you decant a wine too aggressively or too early, it can lose freshness.

This is most dangerous with older bottles.

An old wine may open beautifully for a short time, then fade. If you expose it to too much air, the aromas can flatten and the wine can feel tired.

With young wines, over-decanting is usually less risky, but it can still happen. Some wines are more delicate than they look.

That is why tasting matters.

A decanter is a tool, not a rule.

Decanting vs Letting Wine Breathe in the Bottle

Many people open a bottle and let it sit, thinking the wine is breathing.

That can help a little, but not much.

Inside the bottle, only a small surface area of wine is exposed to air. In a decanter, the wine spreads out and gets much more oxygen contact.

So if the goal is real aeration, a decanter works much better than simply pulling the cork and waiting.

If the wine needs air, give it space.

Do You Need an Expensive Decanter?

No.

A decanter can be beautiful, but it does not need to be expensive.

The most important things are:

• clean glass;
• enough room for the wine;
• easy pouring;
• and no unwanted smells.

Even a simple decanter can work well.

For young wines, the shape helps expose wine to air. For old wines, the vessel gives you a clean place to separate wine from sediment.

Decanting at Home

At home, you do not need to perform a formal sommelier ritual.

You can use simple tools:

• a clean decanter;
• a wine key;
• a phone flashlight;
• a steady hand;
• and clean glasses.

For young wine, pour and let it open.

For old wine, pour slowly and watch for sediment.

That is enough.

The point is not to look fancy. The point is to serve the wine better.

Common Decanting Mistakes

Avoid these common mistakes:

• decanting an old wine too aggressively;
• shaking a fragile bottle;
• ignoring sediment;
• using a dirty or smelly decanter;
• heating the wine over a candle;
• taking your eyes off the bottle while pouring;
• assuming every wine needs decanting;
• assuming no wine needs decanting;
• and waiting too long after decanting an older bottle.

Decanting should match the wine.

The better you pay attention, the better your results.

Final Takeaway

Decanting is simple, but the reason behind it matters.

For young wines, decanting gives oxygen. It helps the wine wake up, stretch out, and show more aroma and texture.

For old wines, decanting separates sediment. It lets you pour clean wine while leaving grit behind in the bottle.

Use a candle or phone light when you need to watch for sediment. Pour slowly. Keep your eyes on the bottle. Stop when the wine becomes cloudy.

For young wines, be less afraid to give the wine air. Pour it into a decanter, swirl it, and let it breathe.

The main lesson is this:

Decanting is not about being fancy.

It is about understanding what the bottle needs.

FAQ

What is decanting?

Decanting means pouring wine from its bottle into a decanter.

Why do people decant wine?

People decant wine either to add oxygen to a young wine or to separate sediment from an older wine.

Why decant young wine?

Young wine can be tight or closed. Oxygen can help it open up and show more aroma, texture, and flavor.

Why decant old wine?

Old wine can contain sediment. Decanting helps keep that gritty sediment out of the glass.

Is sediment bad for you?

Sediment is usually not dangerous, but it can feel gritty and unpleasant in the mouth.

Should old wine be decanted aggressively?

No. Older wines can be fragile, so they should be handled gently and poured slowly.

Why use a candle when decanting?

A candle helps you see sediment moving through the neck of the bottle.

Can you use a phone light instead of a candle?

Yes. A phone flashlight can work as a modern light source for watching sediment.

Should the bottle touch the decanter?

Ideally, no. In professional service, the bottle should not clink against the decanter.

Do all wines need decanting?

No. Some wines benefit from decanting, but others are better served directly from the bottle.

How do you know when to stop pouring an old wine?

Stop when you see sediment or cloudiness approaching the neck of the bottle.

What is the biggest lesson from this episode?

The biggest lesson is that young wines are decanted for oxygen, while old wines are decanted for sediment and must be handled carefully.
