Bourbon
Is Jack Daniel's a bourbon or whiskey?
Jack Daniel's is both, depending on which law you read. The bottle says Tennessee whiskey, and that's correct under U.S. state law. The same bottle is legally classified as a straight bourbon whiskey in Canada and under NAFTA-era trade agreements, and that's correct too. Federally, Old No. 7 ticks every box on the bourbon checklist (American-made, more than 51% corn, distilled and barreled within the legal proof limits, aged in new charred oak, no additives), so the U.S. door to "bourbon" is open. The brand has simply chosen not to walk through it.
So is Jack Daniel's bourbon, legally?
Federal bourbon rules are a checklist of six items. A spirit that hits all six can carry the word "bourbon" on the label; missing any one disqualifies it. Jack Daniel's Old No. 7 hits all six.
| Federal bourbon requirement | Jack Daniel's (Old No. 7) |
|---|---|
| Made in the United States | Meets (Lynchburg, Tennessee) |
| Grain bill at least 51% corn | Meets (80% corn, 12% rye, 8% malted barley) |
| Distilled to no more than 80% ABV (160 proof) | Meets (around 70% ABV off the still) |
| Aged in new, charred oak containers | Meets |
| Bottled at 40% ABV (80 proof) or higher | Meets (80 proof for Old No. 7) |
| No additives (color, flavor, or otherwise) | Meets |
The mash bill alone clears the corn requirement by a wide margin: 80% corn is well above the 51% minimum. The aging is done in new, charred American oak barrels, the same kind a Kentucky distiller would use. Nothing is added before bottling.
The result is that the spirit qualifies as bourbon by federal definition. The reason it doesn't say so on the bottle is that the brand and the state of Tennessee have built a separate category around it, and the brand uses that category by choice.
What is the Lincoln County Process, and does it disqualify bourbon?
Before the spirit ever touches a barrel, Jack Daniel's is dripped slowly through a thick column of sugar maple charcoal (the column at the distillery is around ten feet deep). One filtration takes several days. The industry term is charcoal mellowing, and the local name is the Lincoln County Process, after the Tennessee county where the distillery originally sat.
Mechanically, the charcoal absorbs some of the harsher compounds in the raw spirit (the rough new-make notes that mature whiskey loses on its own with time). The result is a softer entering spirit, before the barrel does its work.
Many people assume this step would disqualify the bourbon label, on the grounds that bourbon is supposed to be aged on its own merits with nothing taken away. The U.S. Alcohol and Tobacco Tax and Trade Bureau (the TTB, the federal regulator) has not held that view. Charcoal filtration is allowed under the bourbon rules, and a few bourbons use it. Brown-Forman's own Cooper's Craft is labeled as a Kentucky straight bourbon and uses a similar charcoal filtration step. If filtering through maple charcoal disqualified a spirit from being bourbon, Cooper's Craft could not legally carry the word.
So the Lincoln County Process is not the legal blocker. It is the Tennessee whiskey requirement, but it is not a bourbon disqualifier. Jack Daniel's could keep the process, change nothing about the liquid, and put "Bourbon" on the label tomorrow.
What's actually different about Jack Daniel's compared to a Kentucky bourbon?
Most of the process is the same. The mash bill is in the same family as a typical high-corn Kentucky bourbon. Both use sour mash (a portion of the previous fermentation's residue is added to the new mash to keep the yeast environment consistent). Both age in new charred American oak barrels. Both come off the still in a similar proof range.
| Step | Kentucky bourbon (typical) | Jack Daniel's |
|---|---|---|
| State | Kentucky | Tennessee |
| Grain bill | Around 70% corn, with rye or wheat and malted barley | 80% corn, 12% rye, 8% malted barley |
| Sour mash | Common (most large Kentucky distillers use it) | Yes |
| Charcoal mellowing before barreling | Rare (Cooper's Craft is the well-known exception) | Yes (Lincoln County Process) |
| Barrel | New, charred American oak | New, charred American oak |
| Where it ages | Kentucky rickhouses | Tennessee rickhouses |
The differences come down to two things. One is the state, which matters for the labeling category but not for the spirit itself. The other is the charcoal mellowing step, which sits in the workflow between distillation and barreling. Everything else (the grain, the yeast, the still, the cask) lines up with what a Kentucky bourbon would look like.
If you took the same Jack Daniel's mash bill, ran it through the same stills, and aged it in the same casks in Kentucky without the charcoal filtration, you would have a legal Kentucky bourbon. The Tennessee version adds the charcoal step and gets a different legal name for it.
Why is Tennessee whiskey its own category, then?
Tennessee whiskey is defined by Tennessee state law. The 2013 statute says that to be sold as Tennessee whiskey, a spirit has to:
- Be made in Tennessee.
- Meet every federal requirement for bourbon (the same checklist above).
- Be filtered through maple charcoal before going into the barrel.
- Be aged in new charred oak barrels in Tennessee.
In other words, the state-law definition is "federal bourbon, plus the Lincoln County Process, made and aged here." Every Tennessee whiskey is a bourbon under federal law, with one extra mandatory step layered on top.
There is one grandfathered exception. Prichard's Distillery, which predates the 2013 statute and never used the Lincoln County Process, was carved out and is still allowed to sell its whiskey as Tennessee whiskey without filtering. Every other Tennessee distillery has to run the spirit through the charcoal.
The category exists because Brown-Forman pushed for it. The 2013 law codified what Jack Daniel's was already doing and prevented any new Tennessee distillery from selling Tennessee whiskey without the charcoal step. The state defined the term tightly around the existing practice, and the brand gained a category it could plausibly claim to anchor.
Is Jack Daniel's called bourbon anywhere?
Yes. Under Canadian law and the NAFTA-era trade agreements that govern how spirit categories cross borders, Tennessee whiskey is defined as "a straight bourbon whiskey produced in the state of Tennessee." The same bottle that sits on a U.S. shelf as Tennessee whiskey is legally classified as a kind of bourbon in Canada and treated as bourbon under the trade agreement.
This is not a loophole. It is the international trade view of what the spirit actually is. The U.S. trade representative agreed to this language because it reflects the reality: Tennessee whiskey is a straight bourbon with a specific filtration step and a state of origin attached, and there is no point pretending it is a different product class for trade purposes.
The bourbon-vs-Tennessee-whiskey split is a labeling and identity decision, not a difference in what's in the glass. Federal law says the spirit qualifies as bourbon. The Tennessee state law and the bottle's label say it is Tennessee whiskey. International trade law says it is bourbon again. The liquid wears two labels depending on which legal frame you read it through, and the liquid itself doesn't care.
