Tennessee Whiskey is a premium spirit, distinguished by its specific geographic origin within the state of Tennessee and its adherence to a unique production method known as the Lincoln County Process. This process involves filtering the distilled whiskey through thick layers of sugar maple charcoal before aging, which imparts a smooth and distinctive flavor. By law, Tennessee Whiskey must be made from at least 51% corn, distilled to no more than 160 proof, and aged in new, charred oak barrels, ensuring its quality and consistency. This combination of location, ingredients, and craftsmanship not only defines Tennessee Whiskey but also sets it apart from other types of whiskey, including bourbon, with which it shares some similarities.

History of Tennessee Whiskey

The history of Tennessee Whiskey is deeply intertwined with the American spirit, tracing its origins back to the early settlers of Tennessee. These pioneers brought with them the tradition of distilling, which they adapted to the local resources, giving birth to a distinct type of whiskey. The Lincoln County Process, a defining feature of Tennessee Whiskey, emerged in the 19th century, setting it apart from other spirits. The era of Prohibition posed a significant challenge, halting production and pushing the industry into the shadows. However, the resilience of the distillers and the enduring appeal of Tennessee Whiskey led to a post-Prohibition revival. This period marked the resurgence of established brands and the emergence of new ones, solidifying Tennessee Whiskey’s place in both American history and the global spirits market.

Origins in the United States

The roots of Tennessee Whiskey stretch back to the early European settlers in Tennessee, who applied their ancestral distilling techniques to the abundant corn crops of their new homeland. This adaptation led to the birth of a distinct whiskey that would later be known as Tennessee Whiskey, a spirit deeply embedded in the cultural and agricultural fabric of the United States.

Prohibition’s impact

Prohibition, enacted in 1920, delivered a crippling blow to the Tennessee Whiskey industry, outlawing the production, sale, and transport of alcohol. Many distilleries were forced to close, while others resorted to operating clandestinely. This period significantly disrupted the tradition and continuity of Tennessee Whiskey production, casting a long shadow over the industry.

Post-Prohibition revival

The repeal of Prohibition in 1933 marked a turning point for Tennessee Whiskey. Distilleries began to reopen, and the industry slowly started to rebuild itself. This era witnessed the resurgence of traditional practices alongside innovations in distillation and marketing. The revival not only restored Tennessee Whiskey to its former glory but also set the stage for its evolution into a globally recognized and revered spirit.

Distinct Characteristics of Tennessee Whiskey

Tennessee Whiskey is celebrated for its unique characteristics that distinguish it from other types of whiskey. Central to its identity is the Lincoln County Process, a method where the whiskey is filtered through sugar maple charcoal, imparting a smoothness and distinct flavor profile. Legally, to be labeled as Tennessee Whiskey, the spirit must be produced in Tennessee, made from a mash of at least 51% corn, and aged in new, charred oak barrels. These stringent requirements ensure consistency and quality, preserving the heritage and authenticity of Tennessee Whiskey. Additionally, the spirit’s connection to its specific geographic origin adds to its unique identity, making it a cherished product of the state and a notable contributor to the global whiskey market.

Charcoal mellowing process

The charcoal mellowing process, also known as the Lincoln County Process, is a hallmark of Tennessee Whiskey. In this method, the distilled whiskey is filtered through a thick layer of sugar maple charcoal before aging. This unique step removes impurities and imparts a smooth, mellow character to the whiskey, distinguishing it from other spirits.

Lincoln County Process

The Lincoln County Process is not merely a technique but a tradition that defines Tennessee Whiskey. Beyond its role in flavoring and smoothing the whiskey, it represents a commitment to craftsmanship and quality. This process is so integral to the identity of Tennessee Whiskey that it is legally mandated for a whiskey to bear the Tennessee name.

Legal requirements

Tennessee Whiskey must adhere to specific legal requirements that govern its production. These include being produced in Tennessee, using a mash bill of at least 51% corn, undergoing the Lincoln County Process, and aging in new, charred oak barrels. These regulations ensure the consistent quality and distinctiveness of Tennessee Whiskey.

Specific to Tennessee

What sets Tennessee Whiskey apart is its geographic specificity. Unlike other whiskeys, which can be produced anywhere, Tennessee Whiskey must be crafted within the state’s borders. This geographic designation not only ties the spirit to its regional heritage but also contributes to its unique flavor profile, rooted in the local environment and tradition.

Production Process

The production process of Tennessee Whiskey is a meticulous journey that transforms simple ingredients into a complex and celebrated spirit. It begins with mashing, where a carefully selected mix of corn, rye, and barley is combined with water and cooked to convert starches into fermentable sugars. The fermentation stage follows, introducing yeast strains that convert sugars into alcohol, creating a beer-like liquid called “wash.” Distillation in copper stills then concentrates the alcohol and refines the flavors. The defining step, charcoal mellowing, involves filtering the distilled spirit through sugar maple charcoal, a process unique to Tennessee Whiskey that imparts smoothness. Finally, the whiskey is aged in new, charred oak barrels, where it develops its full flavor profile and amber color over time. Each of these stages is crucial, contributing to the distinctive taste and quality of Tennessee Whiskey.


Mashing is the first step in the production of Tennessee Whiskey, where a specific mix of corn, rye, and barley is combined with water. This mixture is then heated to break down the starches into fermentable sugars, setting the foundation for the whiskey’s flavor profile.

Corn, rye, and barley mix

The mix of corn, rye, and barley is carefully chosen to achieve a balance of sweetness, spiciness, and complexity in the whiskey. Corn contributes the majority, ensuring the whiskey qualifies under legal definitions, while rye and barley add depth and nuance to the flavor.


During fermentation, yeast strains are introduced to the mash, converting the sugars into alcohol. This stage is critical for developing the base flavors of the whiskey, with different yeast strains contributing various flavor profiles and aromas.

Yeast strains

Yeast strains are selected based on their ability to produce desirable flavors and tolerate high alcohol levels. Each strain imparts unique characteristics to the whiskey, influencing its final taste and complexity.


Distillation concentrates the alcohol and flavors, separating the desired spirit from the wash. Conducted in copper stills, this process is vital for refining the whiskey and ensuring its purity and taste.

Copper stills

Copper stills are favored for their ability to remove sulfur compounds and other impurities, enhancing the smoothness and quality of the whiskey. Their use is a testament to the tradition and craftsmanship in Tennessee Whiskey production.

Charcoal Mellowing

Charcoal mellowing, or the Lincoln County Process, is a defining characteristic of Tennessee Whiskey. The distilled spirit is filtered through sugar maple charcoal, smoothing the whiskey and imparting a unique flavor.

Sugar maple charcoal

Sugar maple charcoal is made by burning sugar maple wood, creating a charcoal that is both highly absorbent and flavorful. This charcoal is essential for the mellowing process, contributing to the whiskey’s smoothness and distinct taste.


Aging in new, charred oak barrels allows the whiskey to mature, developing a rich color, complexity, and depth of flavor. This process can last several years, with the wood interacting with the whiskey to create its final character.

New, charred oak barrels

New, charred oak barrels are used for aging, as the charring process caramelizes the wood sugars, infusing the whiskey with vanilla, caramel, and woody flavors. This step is crucial for achieving the signature taste of Tennessee Whiskey.

Differences Between Tennessee Whiskey and Bourbon

While Tennessee Whiskey and Bourbon share many similarities, key differences set them apart. The most notable distinction is the geographic designation; Tennessee Whiskey must be produced in Tennessee, whereas Bourbon can be made anywhere in the United States. Additionally, Tennessee Whiskey undergoes the Lincoln County Process, involving filtration through sugar maple charcoal before aging, a step not required for Bourbon. This process imparts a unique smoothness and flavor profile to Tennessee Whiskey, distinguishing it from its Bourbon counterpart. Despite these differences, both spirits must be made from a mash containing at least 51% corn and aged in new, charred oak barrels, underscoring their shared heritage and the nuances that define American whiskey.

Geographic designation

A fundamental difference between Tennessee Whiskey and Bourbon is their geographic designation. Tennessee Whiskey, as the name suggests, must be produced within the state of Tennessee, tying it intrinsically to the region’s culture and distilling traditions.

Must be produced in Tennessee

This requirement that it must be produced in Tennessee not only influences the identity of the whiskey but also ensures that the production methods and environmental factors unique to the region are preserved, contributing to the spirit’s distinctive character.

Charcoal mellowing

Another key distinction is the charcoal mellowing process, also known as the Lincoln County Process. This involves filtering the whiskey through layers of sugar maple charcoal before aging, a step exclusive to Tennessee Whiskey that enhances its smoothness and imparts a unique flavor profile.

Not required for bourbon

For Bourbon, the charcoal mellowing process is not required, allowing for a broader range of flavor profiles and production techniques. This difference underscores the specific traditions and legal definitions that distinguish Tennessee Whiskey from its Bourbon counterpart.
