TENNESSEE WHISKEY
Tennessee whiskey is, by the rules, a bourbon — at least 51% corn, distilled low, aged in new charred oak — with two extra requirements: it must be made in Tennessee, and the fresh spirit must be filtered through sugar-maple charcoal before it goes into the barrel. That charcoal step, the Lincoln County Process, is what sets the style apart from Kentucky bourbon. So every Tennessee whiskey is a bourbon, but not every bourbon is a Tennessee whiskey.
- A bourbon made in Tennessee that also undergoes the Lincoln County Process.
- Shares the bourbon rules: ≥51% corn, distilled ≤80% ABV, new charred oak, bottled ≥40%.
- Lincoln County Process = filtering the new spirit through sugar-maple charcoal before barreling.
- Made a legal requirement by Tennessee state law in 2013 (one grandfathered exemption).
- The charcoal step is subtractive — it mellows the spirit, it doesn't add flavour.
- Jack Daniel's and George Dickel are the two largest producers.
The defining move happens before the barrel. Fresh off the still, the clear spirit is dripped or steeped slowly through several feet of charcoal made from burned sugar-maple — a technique known as charcoal mellowing, or the Lincoln County Process, after Jack Daniel's original home county. It's a subtractive step: under the same no-additives logic as bourbon, it removes rougher notes and rounds the spirit rather than adding anything, which is why Tennessee whiskey often reads softer than a comparable Kentucky bourbon even though the two share a rulebook otherwise.
Strip away the charcoal and the geography and Tennessee whiskey is bourbon — same grain, distillation and barrel rules. A 2013 state law added the two extras: the Lincoln County Process and production wholly within Tennessee.

Collector Note
Interest here tends to follow the producers and their small-batch or higher-proof releases — single-barrel and barrel-proof Tennessee bottlings, and the occasional aged or commemorative edition. Because the category shares bourbon's no-additives rules, what's in the glass is grain, charcoal and oak. As with any whiskey, keep them upright in a cool, dark spot, original packaging intact where it matters. Whiskey is stable in glass — what's bottled won't mature further, since an age statement counts barrel time only.
Recommended Serving
Tennessee whiskey takes well to neat or on-the-rocks pours, and its rounded character makes it a dependable base for classics like the whiskey sour, the old fashioned, and the highball. Higher-proof releases reward a few drops of water.
Production Methodology
Production follows the bourbon template: a mash of at least 51% corn (with rye, wheat or malted barley making up the rest), fermented, distilled to no more than 80% ABV, and matured in new charred oak. The Tennessee difference comes between the still and the barrel. The clear new-make spirit is passed through a deep bed of sugar-maple charcoal — Jack Daniel's burns its own maple to make it — in the step codified as the Lincoln County Process. Larger producers vary the details: George Dickel chills the spirit before filtering and lets it steep, while others drip it through. After mellowing, the spirit is barreled and aged in Tennessee, then bottled there, all as required by the 2013 state law.

Frequently Asked Questions
What makes Tennessee whiskey different from bourbon?
Tennessee whiskey meets every federal requirement for bourbon — at least 51% corn, distilled no higher than 80% ABV, aged in new charred oak, bottled at 40% or more — and then adds two things: it must be made in Tennessee, and the new-make spirit must be filtered through sugar-maple charcoal before barreling, a step called the Lincoln County Process. So all Tennessee whiskey is bourbon, but not all bourbon is Tennessee whiskey.
What is the Lincoln County Process, and what does it do?
It's charcoal mellowing: before going into the barrel, the fresh spirit is filtered slowly through several feet of sugar-maple charcoal. Named for Jack Daniel's original home county, it became a legal requirement for the "Tennessee Whiskey" label under a 2013 state law, with one grandfathered exemption. The filtration is subtractive — it rounds and mellows the spirit before aging rather than adding flavour — and it's the main thing that sets the style apart from Kentucky bourbon.
