When diving into the world of spirits, many newcomers often ask: what is the difference between whisky and bourbon? While both are beloved types of distilled spirits, understanding their distinctions can enhance your appreciation and enjoyment. This beginner’s guide will take you through the essential elements that set whisky and bourbon apart, including their ingredients, production processes, and regional regulations.
What is Whisky?
Whisky, a broad term that encompasses a variety of distilled spirits, is made from fermented grain mash. The grains used can include barley, corn, rye, and wheat, and the choice of grain can significantly impact the flavor profile. Whisky is aged in wooden casks, typically oak, which contributes to its complex character.
Types of Whisky
There are several types of whisky around the world, each with its unique characteristics:
- Scotch Whisky: Made in Scotland, typically from malted barley.
- Irish Whiskey: Known for its smoothness, often triple distilled.
- American Whiskey: Includes bourbons and ryes, each with distinct regulations.
- Japanese Whisky: Often inspired by Scotch, known for its craftsmanship.
What is Bourbon?

Bourbon is a specific type of American whisky that adheres to strict regulations. To be classified as bourbon, the spirit must be made primarily from corn (at least 51%), aged in new charred oak barrels, and distilled to no more than 160 proof. Its sweetness and rich flavor make it a favorite among many whisky enthusiasts.
Key Characteristics of Bourbon
- Grain Composition: Must be at least 51% corn.
- Barrel Requirement: Aged in new charred oak barrels, which imparts a deep color and flavor.
- Distillation: Cannot be distilled higher than 160 proof, ensuring more flavorful compounds remain.
- Geographic Requirement: While often associated with Kentucky, bourbon can be made anywhere in the United States.
Comparing the Production Processes

Ingredients
One of the most significant differences when considering what is the difference between whisky and bourbon is the grain composition. While whisky can be made from various grains, bourbon must be made from a minimum of 51% corn. This requirement gives bourbon its characteristic sweetness, which is less prominent in other types of whisky.
Distillation and Aging
The distillation process also varies between the two. Bourbon must be distilled to a maximum of 160 proof, while other whiskies can be distilled higher. Additionally, bourbon’s aging process requires new charred oak barrels, which must be used only once. In contrast, other whiskies might use previously used barrels, leading to different flavor profiles.

When exploring the flavors of whisky versus bourbon, it’s essential to understand their unique qualities:
