Tennessee Whiskey
Bourbon's rulebook plus the Lincoln County Process — made only in Tennessee.
Tennessee whiskey is a bourbon made within Tennessee's borders and filtered through sugar-maple charcoal before it enters the barrel. The state defines the category by two additions to the federal bourbon standard: place of origin and the Lincoln County Process. The result is a smoother, softer American whiskey that shares bourbon's DNA but develops a distinct mellowness from its mandatory charcoal-mellowing step.
Overview
Mash Bill
Tennessee whiskey inherits bourbon's ≥51% corn requirement, but the remaining grain mix varies by producer. Most Tennessee mash bills stay corn-heavy with a low-to-moderate rye percentage, though wheated and rye-forward versions exist. The grain profile sets the baseline flavor before charcoal and oak take over.
How Tennessee Whiskey Is Made
Tennessee whiskey follows the same core steps as bourbon — mash, ferment, distill, age in new charred oak — with one mandatory addition: the Lincoln County Process. This sugar-maple charcoal filtration happens before the spirit enters the barrel, and state law requires it for any whiskey labeled 'Tennessee whiskey.'
Aging
Unlike bourbon's 'straight' label requiring two years, standard Tennessee whiskey has no federal minimum age — state law only requires that the spirit mature in new charred oak. Most bottlings sit four to seven years in Tennessee's warm warehouses, where humid summers and cold winters drive aggressive extraction from the wood.
Flavor
Tennessee whiskey tastes close to bourbon at first sip — sweet, vanilla, oak — but the Lincoln County Process strips some of the corn oils and rough congeners before barreling, leaving a smoother, mellower spirit. The result is usually softer and cleaner than Kentucky bourbon, with less char bite and a rounder sweetness.
Proof & ABV
Tennessee whiskey follows the same proof rules as bourbon: distilled to no more than 160 proof, entered into the barrel at no more than 125 proof, and bottled at no less than 80 proof. Most standard bottlings land between 80 and 100 proof, with single barrel and barrel proof expressions pushing higher.
Rules & Regulations
Tennessee whiskey meets the federal bourbon standard of identity — ≥51% corn, new charred oak, no additives, bottled at 80 proof or higher — then adds two Tennessee-specific rules: it must be made in Tennessee and must be charcoal-filtered using the Lincoln County Process before barreling.
The Lincoln County Process
The Lincoln County Process is a mandatory pre-aging filtration that drips new-make spirit through a thick bed of sugar-maple charcoal before it enters the barrel. Tennessee state law requires it for any whiskey labeled 'Tennessee whiskey' — the step strips harsh congeners and delivers the category's signature mellow profile. One grandfathered exception exists, but the process defines the style.
History
Tennessee whiskey's story begins in the early 1800s when Scots-Irish settlers distilled surplus corn and experimented with charcoal filtration. The Lincoln County Process predates the state's 2013 statutory definition by nearly two centuries. Prohibition shut the industry down, and only a handful of distilleries rebuilt — leaving Tennessee whiskey a tightly held category until the 2000s craft revival.
Tennessee Whiskey vs Bourbon
Every Tennessee whiskey meets the federal bourbon standard — same grain bill, same barrels, same proof rules. The only two things separating them are geography and the Lincoln County Process. Tennessee producers chose decades ago not to label their product as bourbon, and state law now enforces that distinction.
