Bourbon Barrel Smoking Wood: Are You Actually Tasting Bourbon?

Bourbon Barrel Smoking Wood: Are You Actually Tasting Bourbon?

Bourbon barrel smoking chunks sound damn good.

There’s oak. There’s fire. There’s bourbon. Put all three words on a bag and it practically sells itself.

But there’s one question nobody seems to ask:

When you throw pieces of an old bourbon barrel into your smoker, are you actually putting bourbon flavor into your food?

Not really.

You’re primarily smoking with oak.

And there’s a pretty important difference.

A Bourbon Barrel Starts as Oak

Real bourbon is aged in new, charred oak containers. That charred oak plays a huge role in developing the color, aroma and flavor we associate with bourbon.

The whiskey pulls compounds from the oak during aging. Oak lactones, vanillin and other compounds contribute notes we perceive as vanilla, wood, spice and other familiar barrel-aged characteristics.

In other words, the barrel helps flavor the bourbon.

That doesn’t automatically mean the process works backward when somebody cuts that empty barrel into chunks and throws it in a smoker.

A bourbon barrel isn't a flavor sponge waiting to give years of bourbon aging back to your brisket.

Bourbon Flavor and Wood Smoke Aren't the Same Thing

This is where the marketing gets ahead of the science.

Wood smoke develops as the components of the wood break down under heat. Lignin, cellulose and hemicellulose produce hundreds of compounds during combustion and pyrolysis, including the phenolic compounds responsible for much of what we recognize as smoke flavor.

That’s why wood species matters.

Oak doesn't taste like hickory.

Hickory doesn't taste like cherry.

Cherry doesn't taste like maple.

And bourbon isn't a wood species.

When bourbon-barrel wood burns, the dominant material creating your smoke is still oak.

Whatever whiskey aroma remains in an emptied barrel may smell fantastic when you open the package. That's not the same thing as delivering a meaningful, controlled bourbon flavor through combustion.

But I Can Smell the Bourbon in the Wood

Absolutely.

A recently emptied barrel can retain whiskey and aromatic compounds.

You may smell bourbon when you open the bag. You may even smell something different when the wood first heats.

But aroma coming off a piece of barrel wood before or during combustion isn't necessarily the flavor that deposits on your food during a several-hour cook.

Highly volatile compounds behave very differently once they're exposed to fire.

The smoke compounds that actually build barbecue flavor are largely being created by the wood itself.

So that expensive bourbon-barrel chunk?

It's still doing most of its work because it's oak.

And About That Char...

The blackened inside of a bourbon barrel looks impressive.

It also makes the product incredibly easy to market.

But char shouldn't be confused with some secret reservoir of bourbon flavor.

Char is part of what allowed the barrel to transform the whiskey during aging. Once you're standing in front of a smoker, however, your job is different.

You want controlled combustion and good smoke.

That's why we pay attention to things like:

Wood species.

Moisture.

Piece size.

Airflow.

Cleanliness.

And how that piece of wood actually burns.

The picture of a bourbon bottle on the bag doesn't control any of those things.

The Barrel Already Did Its Job

Here's the part I think gets completely backward.

The barrel existed to change the bourbon.

Bourbon spent its aging time interacting with that oak, extracting wood-derived compounds and developing flavor through a complicated combination of extraction, oxidation and time.

Then the bourbon was dumped.

Now we're taking the used barrel and selling it as though the barrel somehow became a better smoking wood because whiskey once lived inside it.

That's a hell of a story.

But a good story and good smoke aren't necessarily the same thing.

Is Bourbon Barrel Wood Bad for Smoking?

No.

And that's important.

If it's genuine, clean oak barrel wood, it can absolutely be used for smoking.

Oak is a fantastic smoking wood.

The issue isn't that bourbon barrel chunks are useless.

The issue is paying a premium because you expect them to turn a rack of ribs into some kind of bourbon-infused masterpiece.

If you like them, use them.

Just understand what you're actually buying.

Used oak with a really good backstory.

If You Want Oak Flavor, Start With Good Oak

I'd rather choose my smoking wood based on the characteristics that actually affect the fire.

I want to know the species.

I want clean hardwood.

I want properly sized pieces.

I want controlled moisture.

And I want predictable combustion.

That's what gives a pitmaster control.

At Tennessee Cooking Wood, that's why we obsess over the wood itself instead of trying to dress it up with a gimmick.

White Oak should be White Oak.

Red Oak should be Red Oak.

Hickory should be Hickory.

Cherry should be Cherry.

Each one already brings something different to the cook.

It doesn't need a bourbon label to make it interesting.

Want Bourbon Flavor? Use Bourbon.

This is the beautifully simple part.

If bourbon is a flavor you actually want in the finished dish, use bourbon as an ingredient where you can control it.

Put it into a sauce, glaze or another part of the recipe where the flavor has an opportunity to remain in the food.

Don't rely on burning an old barrel and hoping the word bourbon somehow survives the fire.

Then let your smoking wood do what smoking wood does best.

Build the smoke.

Build the bark.

Build the aroma.

And complement the food.

Because charcoal is fuel.

Wood is flavor.

And bourbon?

That's bourbon.
