Tennessee Whiskey
What is Tennessee whiskey?
Tennessee whiskey is an American whiskey made in Tennessee that follows the same rules as bourbon, plus one extra requirement: before it goes into the barrel, it has to be filtered through a thick column of sugar-maple charcoal, a step called the Lincoln County Process. Legally, it is a subtype of bourbon under US federal law and the 1994 NAFTA trade agreement, with Tennessee state law codifying the charcoal-filtering step as a binding requirement in 2013. That filter step pulls out some of the rawer flavor elements before the spirit meets the oak, giving Tennessee whiskey a rounder, sweeter character than a typical bourbon. The category is small and brand-concentrated: Jack Daniel's, George Dickel, and Uncle Nearest are the names a new drinker is most likely to recognize.
Is Tennessee Whiskey the Same Thing as Bourbon?
Legally, yes. Tennessee whiskey meets every part of the federal definition of bourbon, which is why US law and international trade law both treat it as a kind of bourbon. What makes the category its own thing is a pair of extras on top of the bourbon rules: it has to be made in Tennessee, and it has to be filtered through sugar-maple charcoal before barreling. Everything else comes straight from the bourbon standard.
The simplest way to hold this in your head is "bourbon plus two rules." A bottle of Jack Daniel's uses a corn-majority mash bill, a new charred-oak barrel, and all the same distillation and proof limits a Kentucky bourbon has to hit. The only thing setting it apart is the place of origin and the charcoal-filter step.
| Rule | Applies to |
|---|---|
| At least 51% corn in the mash bill | Both |
| Aged in a new charred-oak barrel | Both |
| Distilled to no more than 160 proof (80% ABV) | Both |
| Entered into the barrel at no more than 125 proof (62.5% ABV) | Both |
| Bottled at no less than 80 proof (40% ABV) | Both |
| No additives or coloring | Both |
| Made in the United States | Bourbon |
| Made in the state of Tennessee | Tennessee whiskey only |
| Filtered through sugar-maple charcoal before barreling (the Lincoln County Process) | Tennessee whiskey only |
There is one named exception. When Tennessee wrote its 2013 state law, Benjamin Prichard's was grandfathered out of the Lincoln County Process requirement. Their bottles are legally Tennessee whiskey without the charcoal-filter step. Everyone else in the category has to do it.
So why don't producers call it bourbon? Mostly because they don't want to. The "Tennessee whiskey, not bourbon" framing is a producer and cultural preference, not a legal one. A Jack Daniel's bottle could accurately be labeled a bourbon under federal law. The company simply chooses not to, and has chosen not to for over a century. Every rule a bourbon has to meet is a rule Tennessee whiskey has to meet too, with the two Tennessee-specific additions layered on top.
What Does the Lincoln County Process Do?
The Lincoln County Process is a filtration step that happens between distillation and aging. Before the new whiskey goes into its barrel, it runs slowly through a thick column of charcoal made from burned sugar-maple wood. At Jack Daniel's, the charcoal column is about 10 feet deep and densely packed, and the spirit takes several days to pass through it, dripping in at the top and collecting at the bottom.
The charcoal pulls out some of the heavier, sharper flavor elements of the raw spirit. What comes off the filter is a cleaner, softer liquid than what went in. When that liquid then sits in a new charred-oak barrel for years, the result is noticeably rounder than a typical bourbon made from the same mash bill and aged the same way. The underlying recipe is the same as bourbon; the charcoal step takes the edges off before the oak gets involved.
This is a pre-barrel step, not a bottling step. It is not the same thing as the activated-carbon filtering some producers do at the end to clean up a spirit just before it goes into the bottle. The Lincoln County Process happens first, on the raw distillate, and its effect is then shaped and deepened by years in the barrel.
The technique is usually credited to Alfred Eaton, a Lincoln County distiller who was working in the 1820s. Tennessee distillers had been using a version of it for decades before anyone wrote it into a law, and it is the reason the category exists as its own thing rather than just "bourbon made in Tennessee." The mellowing effect the charcoal has on the spirit is the main thing the step is there to do, and sugar maple specifically is used because it burns cleaner and denser than other local hardwoods, giving a charcoal with more surface area per cubic foot.
What Does Tennessee Whiskey Taste Like?
Tennessee whiskey shares bourbon's core character: sweet corn, caramel, vanilla, and toasted oak from the new charred-oak barrel. What sets it apart is the rounding effect of the charcoal step. The same flavors are there, but the harder edges are softer and the sweeter notes come forward more.
Typical descriptors in the category include brown sugar, maple, baking spice, banana, and a soft woodsmoke note. The finish tends to be shorter and warmer than a comparable bourbon, with less of bourbon's sharp rye-heat on the way down. If you have been drinking Kentucky bourbons and you pour a Tennessee whiskey next, the first thing you notice is usually that the back end of the sip feels calmer.
Individual bottles still vary a lot. Jack Daniel's Old No. 7 is sweeter and more banana-forward than George Dickel No. 12, which leans drier and a little waxy. A cask-strength Uncle Nearest drinks closer to a straight Kentucky bourbon than either of them. The category signature is real, but it sits on top of the producer's house style, not underneath it.
The useful framing is "same flavor family as bourbon, but rounded and sweeter." Not a different spirit, and not a completely transformed one. A bourbon drinker poured a glass of Tennessee whiskey will recognize almost everything in it.
Did you know? In blind side-by-side tastings, experienced whiskey drinkers routinely struggle to tell Tennessee whiskey apart from bourbon. The Lincoln County Process softens the spirit noticeably, but it does not change the underlying bourbon character. The category tastes more like bourbon than either its producers or its fans usually acknowledge.
Most of the flavor Tennessee whiskey carries comes from the same two places bourbon's does: the corn in the mash bill and the new charred oak of the barrel. The charcoal step shifts how those flavors land on the palate rather than adding new ones.
Which Whiskeys Count as Tennessee Whiskey?
The category is small and brand-concentrated. Four bottles do most of the work of defining it:
- Jack Daniel's. By far the largest producer, responsible for most of the category's global volume. Distilled in Lynchburg and the reason "Tennessee whiskey" is a recognizable term outside the US at all.
- George Dickel. The other long-established name, distilling in Cascade Hollow since 1870. Uses a slightly different version of the Lincoln County Process (the spirit is chilled before it hits the charcoal) and comes off drier than Jack.
- Uncle Nearest. Launched in 2017, named for Nathan "Nearest" Green, the enslaved master distiller who taught Jack Daniel the craft. Its main bottles sit in a higher price tier than Jack or Dickel and drink closer to a Kentucky bourbon.
- Benjamin Prichard's. The grandfathered exception. Their bottles skip the Lincoln County Process and still qualify as Tennessee whiskey under the 2013 state law.
The category is also growing. A number of post-2010 Tennessee distilleries now bottle Tennessee whiskey, including Nelson's Green Brier, Leiper's Fork, Corsair's Tennessee line, and Company Distilling. None of them are close to Jack Daniel's volume, but they have added variety at the edges.
Not everything made in Tennessee qualifies, though. A Tennessee distillery that produces a whiskey without running it through the Lincoln County Process (and without Prichard's grandfathered exemption) has made an American whiskey, not a Tennessee whiskey. Place of origin alone is not enough. If you see a Tennessee-distilled bottle labeled "straight bourbon" or just "whiskey" rather than "Tennessee whiskey," that is usually why.
The roster of active Tennessee whiskey producers has roughly doubled since the 2013 law took effect, as new Tennessee distilleries have added their own bottles alongside the four anchor brands. And because the category is strictly tied to the state, a Canadian whisky like Crown Royal is not a Tennessee whiskey no matter how familiar the name is on an American back bar.
Tennessee whiskey is not a category that had to be defended against bourbon. It is a category that was formalized around a local technique its producers had already been using for nearly two centuries. The 2013 state law did not invent Tennessee whiskey. It put a fence around something Lincoln County distillers had been doing since the early 1800s, and called that fenced-off thing by its own name.
