Introduction

I recently got a chance to review the brand new Woodford Reserve 12 Year American Single Malt. The American whiskey scene is booming—and evolving. While bourbon has long been the reigning monarch of American whiskey, a new contender is making waves: American Single Malt (ASM). With bold flavor profiles, deep roots in tradition, and a modern twist, ASM is becoming more than just a trend—it’s a movement.

In this in-depth article, we’ll explore how bourbon and American Single Malt stack up, what defines each category, where ASM is heading, and why it’s time to take this rising star seriously.

What Is Bourbon?

Bourbon is America’s signature whiskey, rooted deeply in the country’s history and law. To be legally considered bourbon, a whiskey must meet the following criteria:

• Made in the U.S.
• Distilled from at least 51% corn
• Aged in new, charred oak barrels
• Distilled to no more than 160 proof (80% ABV)
• Entered into the barrel at no more than 125 proof
• Bottled at 80 proof or higher
• No added flavoring or coloring

These regulations ensure consistency and a flavor profile that typically includes caramel, vanilla, spice, and oak. Kentucky is widely considered the bourbon capital of the world, but bourbon can be produced anywhere in the U.S.

What Is American Single Malt Whiskey?

Until recently, American Single Malt Whiskey lacked a formal legal definition—unlike Scotch or bourbon. However, in 2022, the Alcohol and Tobacco Tax and Trade Bureau (TTB) issued a notice of proposed rulemaking to officially recognize American Single Malt as its own category. As of 2023, it is now formally defined under U.S. regulations.

According to the TTB, American Single Malt must be:

• Made from 100% malted barley
• Distilled entirely at one U.S. distillery
• Mashed, distilled, and matured in the U.S.
• Matured in oak casks not exceeding 700 liters
• Distilled to no more than 160 proof
• Bottled at no less than 80 proof (40% ABV)

This codification brings American Single Malt in line with international standards like those for Scotch Single Malt but allows room for American creativity.

Key Differences: Bourbon vs. American Single Malt

Why American Single Malt Is Gaining Momentum

The demand for authenticity, craftsmanship, and unique regional expression has led to a surge in American Single Malt production. Whiskey enthusiasts and newcomers alike are seeking bold, expressive alternatives to bourbon—and ASM delivers.

Some reasons for the rise:

• Creative freedom: ASM distillers experiment with barley strains, aging techniques, and barrel finishes.
• Cultural shift: A new generation of whiskey drinkers is looking for something that feels both traditional and new.
• Global appeal: International markets familiar with Scotch are intrigued by America’s take on the single malt concept.

Distilleries Leading the ASM Revolution

A number of American distilleries have emerged as pioneers of the ASM category, producing world-class expressions that rival long-established Scotch brands. Here are some of the best known and most respected:

🏔️ Stranahan’s (Colorado)

One of the OGs of American Single Malt, Stranahan’s is known for its Rocky Mountain spring water and high-elevation aging. Their expressions like Stranahan’s Original and limited-edition Snowflake Series are cult favorites.

🌲 Westland Distillery (Seattle, WA)

A leader in pushing for official ASM recognition, Westland focuses on Pacific Northwest barley, unique malting processes, and even peated expressions. Their American Oak, Sherry Wood, and Garryana releases showcase complexity and terroir.

🌵 Whiskey Del Bac (Arizona)

Known for its use of mesquite-smoking techniques, Whiskey Del Bac delivers uniquely Southwestern single malts. Their Classic and Dorado expressions are must-tries for fans of bold, smoky profiles.

🥃 Balcones (Texas)

A Texas powerhouse, Balcones experiments with wild yeast strains and intense heat aging. Their Texas Single Malt is rich, bold, and distinctly American.

🌊 McCarthy’s (Oregon)

Using imported peat-smoked malt from Scotland and aged in Oregon oak, McCarthy’s makes a smoky, Islay-inspired single malt with Pacific Northwest soul.

ASM vs. Scotch: A Different Breed

While American Single Malt draws inspiration from Scotch, it’s not simply a copy.

• Climate: American climates vary more dramatically, leading to faster aging in some regions (especially Texas and Colorado).
• Barrel experimentation: Unlike Scotch, which mainly uses ex-bourbon casks, American Single Malts frequently explore new oak, wine casks, or even mesquite smoke.
• Flavor: ASM often leans bolder and richer, with a signature American intensity.

The Future of American Whiskey

With TTB recognition, ASM is poised for exponential growth. Expect to see:

• More shelf space: Retailers and bars are beginning to create separate ASM sections.
• Increased exports: International curiosity around ASM is rising.
• Cask-finished expressions: Expect port, sherry, wine, and stout cask finishes to become the norm.
• Craft distillery boom: More small producers are entering the space, adding diversity and creativity.

Should Bourbon Fans Care About ASM?

Absolutely. While bourbon offers consistency and tradition, American Single Malt brings adventure and nuance. Think of it not as competition—but as complementary. Many whiskey lovers are now keeping both on their shelves.

Pair your pour:

• Bourbon with BBQ or pecan pie.
• ASM with dark chocolate, smoked meats, or a fire on a cool evening.

Final Thoughts

Bourbon may be king, but American Single Malt is earning its crown. With formal recognition, passionate distillers, and a growing fan base, ASM isn’t just a trend—it’s the next chapter in American whiskey.

Whether you’re a die-hard bourbon fan or new to the whiskey world, give American Single Malt a sip—you might just discover your next favorite bottle.
