đŸ„ƒ Bourbon vs. Tennessee Whiskey vs. American Single Malt: What’s the Difference?

May 8, 2025by Wooden Cork

When it comes to American whiskey, many drinkers are familiar with names like Jack Daniel’s, Maker’s Mark, and Westland. But behind the labels lie distinct styles shaped by geography, ingredients, and process. If you’ve ever wondered about the difference between Bourbon, Tennessee Whiskey, and the rising star American Single Malt, this guide breaks it all down—whether you're a collector, casual sipper, or new to whiskey altogether.

What Is Bourbon?

  • Made in the U.S. (not just Kentucky!)
  • Mash bill must contain at least 51% corn
  • Aged in new, charred oak barrels
  • Distilled to no more than 160 proof
  • Entered into the barrel at no more than 125 proof
  • Bottled at a minimum of 80 proof

The result? A sweet, full-bodied whiskey with notes of caramel, vanilla, and oak.

Popular Brands: Buffalo Trace, Blanton’s, Woodford Reserve, Four Roses

What Is Tennessee Whiskey?

Tennessee whiskey is technically bourbon—but with a key twist: the Lincoln County Process, where the spirit is filtered through sugar maple charcoal before aging.

  • Meets all the criteria of bourbon
  • Must be produced in Tennessee
  • Must undergo charcoal filtering before aging

This charcoal mellowing softens the spirit and creates a smoother finish.

Popular Brands: Jack Daniel’s, George Dickel, Uncle Nearest

Fun Fact: All Tennessee whiskey is bourbon, but not all bourbon is Tennessee whiskey.

What Is American Single Malt?

American Single Malt is inspired by Scotch but uniquely American, made with 100% malted barley at a single U.S. distillery. There’s no federal legal definition yet, but an industry standard is emerging.

  • Made from 100% malted barley
  • Distilled at a single U.S. distillery
  • Aged in oak barrels (charred or uncharred)
  • Often pot-distilled like Scotch

Popular Brands: Westland, Stranahan’s, Balcones, Copperworks

Trending: American Single Malt is expected to become an officially recognized category soon.
