Can Tennessee whiskey also be called bourbon?

Yes, by law, Tennessee whiskey qualifies as a type of bourbon. It meets every federal requirement that defines bourbon and then adds one more: a filtration through sugar-maple charcoal before the spirit ever touches a barrel, known as the Lincoln County Process. The federal bureau that regulates alcohol labeling (the TTB) has formally recognized Tennessee whiskey as a type of straight bourbon. Almost no producer puts the word "bourbon" on the label anyway, because the state, the industry, and the big brands treat Tennessee whiskey as its own category. The result is a category whose legal identity and commercial identity disagree, which is why the question keeps coming up.

So, Does It Legally Qualify as Bourbon?

Yes. The federal standard of identity for bourbon (27 CFR 5.143) sets seven requirements, and Tennessee whiskey passes every one of them.

Bourbon has to be made in the United States from a grain mixture that is at least 51% corn (the "mash bill," the recipe of grains that gets fermented and distilled). It has to come off the still at no more than 160 proof (proof is double the alcohol-by-volume percentage, so 160 proof is 80% ABV). It has to go into the barrel at no more than 125 proof. The barrel must be new, made of oak, and charred on the inside. Nothing can be added back to it: no colorings, no flavorings, no sweeteners. And it has to be bottled at no less than 80 proof.

Tennessee whiskey, defined under Tennessee Code 57-2-106, requires all of the above, plus two things. It has to be made in Tennessee. And before it goes into the barrel, the new spirit has to be filtered through a bed of sugar-maple charcoal. That filtering step is the Lincoln County Process, named for the Tennessee county where Jack Daniel's was originally based. The charcoal strips out some of the heavier, oilier compounds from the distillate before aging begins.

Every one of those Tennessee-specific requirements is additive. None of them remove Tennessee whiskey from the bourbon standard. This is where the common "it's not bourbon because of the charcoal step" line gets it backwards. The charcoal filtering is permitted under the bourbon rules, not disqualifying.

The TTB (the Alcohol and Tobacco Tax and Trade Bureau) has taken the same position in writing. It recognizes Tennessee whiskey as a type of straight bourbon whiskey. International trade agreements reinforce that reading. NAFTA, and then its replacement USMCA, define Tennessee whiskey as "a straight Bourbon whiskey authorized to be produced only in the State of Tennessee." Bourbon is the genus. Tennessee whiskey is a species of it.

Read it top to bottom and the shape is clear: Tennessee whiskey clears every bar bourbon sets, and then adds two more of its own.

Why Don't the Bottles Just Say "Bourbon," Then?

Branding and regional identity. Not regulation.

Jack Daniel's is the anchor brand of the category, and its entire identity is built on the Tennessee Whiskey label. The brand's own slogan is "It's Not Bourbon. It's Jack." The distillery actively pushed for the 2013 Tennessee state law that codified what a Tennessee whiskey has to be, arguing that the category deserves the same kind of regional protection that Scotch has in Scotland or Champagne has in France. George Dickel, the other major Tennessee producer, follows the same convention.

For these producers, putting "Bourbon" on the front label would dissolve a regional identity they have spent decades building. Tennessee whiskey is positioned as its own American spirit, not a Kentucky one.

A more cynical reading sits alongside the branding one. Keeping "Tennessee Whiskey" as a separate shelf category lets the big Tennessee distillers avoid a direct shelf fight with Kentucky bourbons on Kentucky's home turf. Both readings are true at the same time. The legal status says "bourbon." The marketing says "don't." The industry follows the marketing.

Past the label, Tennessee whiskey and bourbon describe the same underlying spirit with Tennessee adding the charcoal-filtration step on top.

Are There Any Tennessee Whiskeys That Do Label Themselves Bourbon?

Yes. A small handful.

Uncle Nearest is the clearest example. Some of its releases carry both "Tennessee Whiskey" and "Straight Bourbon Whiskey" on the same bottle, and the brand has been public about its position: the product meets both definitions, so both names belong on the label.

Benjamin Prichard's is the other notable case, for a different reason. Prichard's is a Tennessee distillery that was explicitly grandfathered out of the Lincoln County Process requirement when the 2013 state law passed. Its whiskey skips the charcoal filtering step. That means it meets the federal bourbon standard but not the modern Tennessee whiskey standard, so it is, legally, bourbon made in Tennessee.

Prichard's also makes the geographic point on its own. Whiskey made outside Kentucky can still be bourbon, because nothing in the federal standard ties bourbon to a specific state.

The label on a Tennessee-made whiskey is a producer decision inside the bounds of what the spirit actually is. A distiller can lean on the bourbon side, lean on the Tennessee side, or put both on the front. The liquid does not change when the label does. The bourbon rules and the Tennessee whiskey rules both point at the same bottle.
