Bourbon vs Whiskey

Bourbon and whiskey are both distinguished members of the distilled spirits family, with rich histories and diverse flavor profiles.

While all bourbon is whiskey, not all whiskey is bourbon.

Understanding the differences between these two types of spirits is key to enhancing your appreciation of their unique qualities.

Whiskey is a broad category for a type of spirit distilled from a fermented grain mash, which includes various grains such as barley, corn, rye, and wheat.

These grains, along with the distillation process and aging conditions, play vital roles in shaping the characteristic flavors of the whiskey.

Bourbon, a type of American whiskey, has specific legal requirements that set it apart.

It must be made with at least 51% corn, which lends a sweeter taste to the finished product.

Furthermore, it has to be aged in new, charred oak barrels, a factor that imparts bourbon with its distinctive vanilla and caramel notes.

The aging process must take place in the United States, and no artificial coloring or flavoring can be added.

These criteria are rigorously enforced by law to ensure the quality and consistency that bourbon enthusiasts have come to expect.

When selecting a bottle for your collection or a glass to enjoy, consider the nuances of bourbon and whiskey.

Whether served neat, on the rocks, or as the foundation for a classic cocktail, each offers a unique experience.

Bourbon often presents a more robust sweetness and full-bodied complexity due to its corn content and aging process, while whiskeys, depending on their grain composition and geographic origin, can range from smooth and mellow to rich and peaty.

Your preference will guide you, but knowledge of what distinguishes bourbon from other whiskeys will enrich your tasting journey.

Defining Bourbon and Whiskey

When you explore the world of spirits, you’ll find that bourbon and whiskey are distinct, though related, types of alcoholic beverages.

Whiskey is a broad category of spirits distilled from fermented grain mash, which may include barley, rye, wheat, and corn. The aging process takes place in wooden barrels which impart unique flavors. Whiskey’s sub-types are often regionally defined, such as Scotch whisky (notably spelt without the “e”), which hails from Scotland, or Irish whiskey, with its smooth finish.

Bourbon, on the other hand, is a type of American whiskey with stringent production regulations.

To qualify as bourbon, the mash must contain at least 51% corn, lending it a distinctive sweetness.

It must also be aged in new charred oak barrels which contribute to its vanilla and caramel notes.

Unlike the broader whiskey category, bourbon must be distilled to no more than 160 proof (80% alcohol by volume) and entered into the barrel for aging at no more than 125 proof (62.5% alcohol by volume).

Main IngredientVaried grains (barley, rye…)Minimum 51% corn
Aging BarrelsCan be new or usedNew, charred oak barrels only
Distillation ProofNo specific regulationMax 160 proof
Entry ProofNo specific regulationMax 125 proof

Other American whiskies include Tennessee whiskey—which is essentially bourbon that undergoes additional filtering—and rye whiskey, which, like bourbon, has specific requirements but is made predominantly from rye grain instead of corn.

Outside America, Japanese whiskey has gained recognition, drawing inspiration from Scotch and often adhering to their production practices.

Historical Origins

Your understanding of bourbon and whiskey begins with their distinctive pasts, deeply rooted in location and culture. These spirits have storied origins that reflect their development through time and their cultural significance within their respective regions.

Bourbon History

Kentucky, a state synonymous with bourbon, is often considered its birthplace, though the precise location of bourbon’s origin within the state remains a topic of debate.

Bourbon County, a name that echoes the French Bourbon dynasty, is frequently cited as the namesake for the whiskey.

The history of bourbon whiskey is, in many ways, the history of the United States.

It’s widely believed that the spirit gained its name in the 1850s. The use of corn, a staple crop in the U.S., distinguishes bourbon from other whiskeys.

Whiskey Evolution

The history of whiskey spans several countries, most notably Scotland and Ireland, where the terms “whisky” and “whiskey” respectively took root.

The name itself has Celtic origins, derived from the Latin word aqua vitae, interpreted as “water of life” in the Gaelic languages.

The Scottish and Irish methods and traditions of whiskey-making have evolved over centuries, influencing its production across the world, particularly in what developed into the distinct American styles.

Production Processes

When you explore the nuances of whiskey and bourbon production, key processes such as distillation and aging play pivotal roles in defining each spirit’s unique profile and taste.

Distillation Process

The process begins with a mash bill, a specific mixture of grains that ferment to create alcohol.

Whiskey can be made from a variety of grains, including rye, wheat, barley, and corn, but for a spirit to be labeled as bourbon, the mash bill must contain at least 51% corn.

The mixture of fermented grains is then distilled to increase the alcohol content.

Distillation typically takes place in two main types of stills:

  • Pot stills, generally used for single malt whiskies.
  • Column stills, often preferred for bourbon and other American whiskies, as they allow for continuous distillation.

This process separates the alcohol from the fermented mixture by heating it into a vapor, which then recondenses back into liquid form, increasing the purity and alcohol content.

Aging and Maturation

After distillation, whiskey and bourbon undergo an aging process in wooden barrels, which significantly influences their flavors and textures.

  • Bourbon must be aged in new, charred oak barrels, which impart a distinct sweetness and notes of vanilla, caramel, and oak to the spirit.
  • While whiskey can also be aged in wooden barrels, regulations concerning the type and treatment of the barrels vary widely depending on the style and region of production.

The interaction between the spirit and the oak barrel during aging introduces additional complexity, softens harshness, and can also deepen the color of the whiskey.

The aging process in charred oak barrels is essential in bourbon production as it is responsible for much of the bourbon’s final character, while in whiskey production, the variety of barrels, including those that are uncharred or previously used, offers a broader spectrum of flavors and maturity levels.

Legal Standards and Regulations

In the world of spirits, the distinctions between bourbon and whiskey are not just a matter of taste but are defined by strict legal standards. These regulations govern everything from the base ingredients to the aging process, ensuring quality and consistency.

United States Laws

The United States maintains precise legal requirements for spirits to be labeled as bourbon. Here are the key criteria you should be aware of:

  • Composition: Bourbon must be made with at least 51% corn.
  • Aging: If aged less than four years, bourbon must inform you about how long it has been aged on the label. However, to be classified as straight bourbon, it needs to be aged for a minimum of two years.
  • Volume: When distilled, bourbon must enter the barrel at no more than 125 proof (62.5% ABV). Moreover, it should not be bottled at anything less than 80 proof (40% ABV).
  • Geography: It must be produced in the U.S. without any specific requirement for it to be made in Kentucky, which is a common misconception.

International Standards

While bourbon is a product distinct to the United States, whiskey, in general, has a set of international standards which vary by country of origin. Here’s what you should know:

  • Criteria: International whiskies often have their regulations, like Scotch or Irish whiskey, which stipulate their unique production methods.
  • ABV: Most countries require a minimum alcohol by volume of 40% ABV for whiskey.
  • Regulations: Criteria such as the types of stills used, aging process, and the use of peat (for flavor) are some of the factors that distinguish international whiskey categories.

Flavor Profiles

Understanding the distinct flavor profiles of bourbon and whiskey is essential for appreciating their unique characteristics.

Characteristic Tastes

When you sip bourbon, expect a sweet flavor that’s deeply rooted in its corn-based mash.

Your palate is likely to detect vanilla and caramel, owing to the charred oak barrels used for aging.

The sweetness may be accompanied by a full-bodied richness and noticeable hints of fruit.

In contrast, whiskey’s flavor spectrum can range from spicy to tart.

For example, rye whiskey offers a sharper spice, akin to black pepper or baking spices, while scotch may introduce peaty flavor nuances.

The intensity of these flavors can vary, with some whiskeys presenting a notable cocoa or a subtler sweet characteristic.

Contributing Factors to Flavor

Barrel Aging:

  • Bourbon’s aging in new charred oak barrels imbues it with vanilla and caramel notes.
  • Whiskey aging in used barrels has subtler wood influences, diversifying its flavor profile.

Grain Choice:

  • Bourbons with a high corn mash (>70%) lean towards a sweeter taste.
  • Whiskeys made predominantly with malted barley or rye may exhibit fruitier or spicier notes, respectively.

Distillation Techniques:

Your bourbon’s flavor profile gets shaped during the distillation process, which can either concentrate or soften the sweet and creamy characteristics.

Lastly, the distiller’s choice in yeast strains affects the prevalence of flavor notes of fruit and floral or buttery essence in both bourbon and whiskey, rounding out their distinct palettes.
