What’s the difference between bourbon & whiskey?

Answered by Robert Flynn

Bourbon and whiskey are two popular spirits that have distinct differences in terms of the grains used and the production process. As an avid whiskey enthusiast, I have explored the nuances between these two spirits and can provide a detailed answer to your question.

1. Grain Composition:
– Bourbon: To be classified as bourbon, the mash (the mixture of grains used for fermentation) must contain a minimum of 51 percent corn. This high corn content gives bourbon its characteristic sweetness and smoothness. The remaining grains in the mash typically include barley, rye, or wheat, which contribute to the flavor profile.
– Whiskey: Whiskey, on the other hand, has a broader category and includes various types such as Scotch, Irish, rye, and bourbon. While bourbon is a type of whiskey, not all whiskeys are bourbons. Whiskey can be made from different grains such as barley, rye, wheat, or corn. The specific type of grain used will influence the flavor profile and characteristics of the whiskey.

2. Aging Process:
– Bourbon: One key requirement for bourbon is that it must be aged in new, charred-oak barrels. This aging process imparts rich flavors and color to the spirit. The charred oak barrels contribute to the caramel and vanilla notes often associated with bourbon. By law, bourbon must be aged for a minimum of two years to be called “straight bourbon,” although many premium bourbons are aged for much longer periods.
– Whiskey: While some whiskeys, such as Scotch, may also be aged in oak barrels, there are no specific requirements for the type of barrel or the aging process for whiskey as a whole. Each type of whiskey may have its own aging regulations and traditions. For example, Scotch whisky is often aged in used oak barrels, which can give it unique characteristics.

3. Geographic Origin:
– Bourbon: Bourbon is uniquely American and is often associated with Kentucky, although it can be produced anywhere in the United States. In fact, there are strict legal requirements for a whiskey to be labeled as bourbon in the U.S. These regulations ensure that bourbon is made according to specific standards and traditions.
– Whiskey: Whiskey, on the other hand, is produced globally, with different countries having their own distinct styles and regulations. For instance, Scotch whisky must be produced in Scotland, while Irish whiskey must be made in Ireland. Each region has its own production methods and flavor profiles, making whiskey a diverse and exciting category.

The primary differences between bourbon and whiskey lie in the grain composition, aging process, and geographic origin. Bourbon must contain at least 51 percent corn in its mash and be aged in new, charred-oak barrels, giving it a distinctively sweet and smooth flavor profile. Whiskey, on the other hand, encompasses a broader category of spirits made from various grains and aged in different types of barrels. It is important to note that while bourbon is a type of whiskey, not all whiskeys are bourbons. Exploring the world of bourbon and whiskey can be a fascinating journey, as each type offers its own unique characteristics and regional traditions.
