Tennessee Whiskey vs Bourbon: The Real Differences

Jul 10, 2026by Wooden Cork

All Tennessee whiskey is bourbon's close cousin, but not all bourbon is Tennessee whiskey. The two are often confused, and for understandable reasons: they share most of the same rules. The real difference comes down to one extra step and one matter of geography. Here is what actually separates them.

Key takeaways:
  • Tennessee whiskey must meet all the legal requirements of bourbon, plus more.
  • It must be made in Tennessee.
  • It must use the Lincoln County Process: charcoal filtering before barreling.
  • In short, most Tennessee whiskey is bourbon that takes an extra step.

What Makes a Bourbon

Bourbon has a strict legal definition. It must be made in the United States, from a mash of at least 51 percent corn, aged in new charred oak barrels, distilled to no more than 160 proof, barreled at no more than 125 proof, and bottled at a minimum of 80 proof. It contains no additives beyond water. Contrary to a common myth, bourbon does not have to be made in Kentucky, though most of it is.

What Makes It Tennessee Whiskey

Tennessee whiskey starts by meeting every one of those bourbon requirements. Then it adds two more. First, it must be produced in the state of Tennessee. Second, by state law it must use the Lincoln County Process, in which the new-make spirit is filtered through sugar-maple charcoal before it enters the barrel. That filtering step mellows the whiskey and is the defining signature of the style.

Does the Extra Step Change the Taste?

It can. The charcoal mellowing tends to smooth out some of the harsher notes of the raw spirit, which is part of why Tennessee whiskey is often described as especially smooth and rounded. Bourbon, without that step, can show a bit more raw grain character and spice depending on the producer. The differences are real but subtle, and brand-to-brand variation often matters more than the category line.
