Tennessee whiskey is an American whiskey made to the bourbon standard and then mellowed through a deep bed of maple charcoal before the barrel. Made only in Tennessee, it is rounder and softer for that step.
The closest match, measure for measure. It is made to the same rules, just without the maple-charcoal filtering.
Swaps in the same amount. It tastes sharper and spicier, though in a lemonade or mule the difference almost disappears.
"Jack Daniel’s is a bourbon"
No: it is sold as Tennessee whiskey, a legally separate category. It follows the bourbon recipe; the Lincoln County Process is what sets it apart.
