Facts About Bourbon You Should Know

Some people assume that all whiskeys are the same, while others think bourbon can only come from Kentucky. In reality, bourbon has a very specific definition, a rich heritage, and a set of production rules that make it uniquely American.

In this guide, we’ll cover what bourbon is, how it differs from other whiskies, and 15 amazing facts that even seasoned enthusiasts may not know. 

Whether you’re a novice or a connoisseur, this will give you a fuller appreciation for America’s native spirit, and perhaps even inspire your next exploration with LiquorETC.

What is Bourbon?

For many, bourbon is a comforting companion at the end of a long day. For others, it’s a subject of fascination, a spirit with a story as rich and complex as its flavor.

Bourbon is a type of American whiskey, but not every whiskey can call itself bourbon. U.S. federal law lays out strict guidelines to protect its identity.

To qualify as bourbon, a whiskey must:

• Made in the United States

• Contains at least 51% corn in its mash bill

• Be distilled to no more than 160 proof

• Enter the barrel for aging at no more than 125 proof

• Be aged in new, charred oak barrels

• Contain no added flavors, coloring, or other additives

The 51% corn content is key. Corn provides natural sweetness, which differentiates bourbon from other whiskies. Rye-heavy or barley-heavy spirits tend to be spicier or more astringent, while bourbon offers a warm, smooth palate that is both approachable and complex.

The barrels play a crucial role as well. Charred oak barrels not only impart rich vanilla, caramel, and toffee notes but also interact with the whiskey as it ages, mellowing harsh alcohols and enhancing the overall flavor.

Because of these regulations, bourbon maintains a recognizable profile, yet each distillery still has room for creativity. The type of grains used, the yeast strain, the barrel char level, and aging time all contribute to the wide variety of flavors that bourbon enthusiasts can explore.

How Is Bourbon Different From Other Types of Whiskey?

Whiskey is a broad category encompassing multiple styles from around the world, but bourbon has specific characteristics that set it apart. Understanding these differences can deepen your appreciation of each sip.

1. Bourbon vs. Scotch Whisky

Scotch is produced in Scotland and typically uses malted barley as its main ingredient. Many Scotches are aged in used barrels, such as ex-bourbon or sherry casks, and can feature smoky or peaty flavors from malt kilns or peat fires. Bourbon, by contrast, is sweeter due to its corn content and gets much of its complexity from new charred oak barrels.

For example, a Laphroaig Scotch may have a distinct smoky, medicinal flavor, while a Maker’s Mark bourbon offers smooth caramel and vanilla notes with a gentle warmth. These differences illustrate the cultural and geographical influences that shape each spirit.

2. Bourbon vs. Rye Whiskey

Rye whiskey must contain at least 51% rye, which gives it a spicier, drier profile compared to bourbon. While bourbon leans toward sweet and mellow flavors, rye often delivers bold, peppery, and sometimes fruity notes.

For cocktail enthusiasts, this distinction matters. Rye tends to hold its own in a Manhattan, cutting through the sweetness of vermouth, whereas bourbon provides a smoother, rounder flavor profile that works beautifully in an Old Fashioned.

3. Bourbon vs. Tennessee Whiskey

Tennessee whiskey is technically bourbon in all but name but includes an extra step called the Lincoln County Process, where the spirit is filtered through charcoal before aging. This filtration softens the whiskey, giving it a smoother, slightly mellower character.

Jack Daniel’s is the most well-known example. While its flavor profile is similar to bourbon, the charcoal filtration and often slightly lower aging times create a distinctive signature.

4. Bourbon vs. Irish Whiskey

Irish whiskey is typically triple-distilled and often unpeated, producing a lighter, smoother spirit. Bourbon, in contrast, is usually distilled twice (sometimes once), which preserves more robust flavors from the grains and the barrels.

These differences highlight how ingredients, distillation methods, and aging techniques shape the character of each whiskey, making bourbon uniquely bold yet approachable.

15 Amazing Facts About Bourbon

Here are 15 fascinating facts that will deepen your appreciation for this iconic spirit:

1. Bourbon is America’s only native spirit 

Bourbon has earned recognition from the U.S. Congress as “America’s Native Spirit.” No other spirit has such a distinctly American identity enshrined in law.

2. Bourbon does not have to be made in Kentucky

While Kentucky produces about 95% of the world’s bourbon, it can be made anywhere in the U.S., as long as it follows the legal requirements. Kentucky is famous for its limestone water and favorable climate, which contribute to bourbon’s unique flavor, but the spirit itself is truly American.

3. Corn is the star ingredient 

Bourbon must contain at least 51% corn, but many distillers use 60–75% or more. Corn provides natural sweetness and balance, allowing other grains, like rye or barley, to contribute spice or complexity.

4. New barrels are mandatory

Unlike Scotch or Irish whiskey, bourbon must be aged in new charred oak barrels. This rule ensures a consistent flavor profile and explains why bourbon often carries rich vanilla, caramel, and toffee notes.

5. Char level matters

Barrels are not just toasted, they are charred. This caramelizes the wood sugars and creates compounds that interact with the spirit during aging. Different distilleries use varying char levels to produce signature flavors.

6. Age statements  are meaningful

If a bourbon has an age statement, it refers to the youngest whiskey in the bottle. For instance, a 10-year-old bourbon guarantees that every drop has been aged at least ten years.

7. Bourbon has no minimum aging requirement  

While many believe bourbon must be aged for years, the law only requires new barrels. To be labeled “straight bourbon,” however, it must age for at least two years.

8. Climate plays a huge role

Kentucky’s hot summers and cold winters cause barrels to expand and contract, forcing whiskey into the wood and back into the liquid. This interaction accelerates flavor development and adds depth to the spirit.

9. Bottled-in-bond is a mark of quality 

Bottled-in-bond bourbons must be aged at least four years, bottled at 100 proof, and come from one distillery in a single season. This designation was originally intended to ensure quality and authenticity in the late 1800s.

10. Proof impacts flavor

The higher the proof, the bolder the flavors. Barrel proof bourbons often exceed 120 proof, providing intense flavor and aroma. Adding a splash of water can open up the whiskey, revealing subtle notes that were masked by alcohol.

11. Small batch isn't legally defined

“Small batch” often implies artisanal care or limited production, but there’s no legal definition. It can range from a few barrels to hundreds, depending on the distillery.

12. Single barrel means unique 

Single-barrel bourbons are bottled from one specific barrel. No two barrels are exactly alike, meaning each bottle offers a unique tasting experience. Flavor profiles can vary dramatically, even within the same distillery.

13. Bourbon get its color naturally 

Bourbon never contains artificial coloring. Its rich amber hue comes entirely from the charred oak barrel. Longer aging generally deepens the color, though flavor and balance are more important than hue.

14. Older isn't always better 

While aging adds complexity, over-aging can make bourbon overly woody or bitter. Distillers carefully balance aging time with flavor profile, ensuring each release highlights the spirit’s best qualities.

15. Bourbon is incredibly versatile 

Bourbon shines neat, on the rocks, with a splash of water, or in cocktails. Classics like the Old Fashioned, Manhattan, and Mint Julep showcase bourbon’s flexibility, while modern mixologists continue to push creative boundaries.
