The selection of grains is a pivotal factor that distinguishes bourbon from Scotch whisky, profoundly influencing the final flavor profiles of each spirit. The regulations governing each spirit mandate specific grain compositions, leading to distinct characteristics recognizable to both casual consumers and experienced connoisseurs. The differing use of grains is a primary cause of the divergence in taste, aroma, and texture between these two types of whisky.
Bourbon, by legal definition, must be produced from a grain mixture consisting of at least 51% corn. This high corn content imparts a sweetness and characteristic caramel-like flavor. The remaining grains in the mash bill, often rye, wheat, and malted barley, contribute complexity and spice. In contrast, Scotch whisky, particularly single malt Scotch, relies heavily on malted barley. This grain undergoes a malting process, where the barley is germinated and then dried, often using peat smoke, which imparts the smoky notes often associated with Scotch. Grain whisky in Scotland can utilize other grains, like wheat or corn, but it is the dominance of malted barley that defines many of the styles.
The importance of grain selection extends beyond mere flavor. It affects the entire production process, from fermentation to distillation and aging. The type of grain influences the efficiency of fermentation, the congeners produced during distillation, and the way the spirit interacts with the oak cask during maturation. Understanding these relationships is essential for appreciating the complexities inherent in bourbon and Scotch whisky. The grain selection differences represent a fundamental divergence in production philosophy, and ultimately defines the distinct character of each spirit.
3. Distillation
Distillation plays a crucial role in shaping the final characteristics of both bourbon and Scotch whisky.

These differences arise from variations in still types, number of distillations, and the cuts made during the process.
-
Still Types and Their Impact
Bourbon typically utilizes column stills, pot stills, or a combination of both. Column stills, offering continuous distillation, often produce a lighter spirit with fewer congeners. Pot stills, used more traditionally, allow for batch distillation, resulting in a spirit with more complex flavors and aromas due to higher congener content. Scotch whisky predominantly relies on copper pot stills. These stills contribute to the spirit’s flavor through copper interaction, removing undesirable compounds and promoting the formation of esters, which contribute fruity notes. The shape and size of the pot still further influence the character of the resulting spirit.
-
Number of Distillations
The number of distillations also differentiates bourbon and Scotch whisky. Bourbon is typically distilled to a lower proof, often not exceeding 160 proof (80% ABV), which preserves more of the grain’s character. Scotch whisky frequently undergoes two distillations, although some distilleries employ a triple distillation process. Each distillation refines the spirit, removing impurities and concentrating alcohol. The choice of distillation number is a key factor in determining the final product’s texture and complexity.
-
Cuts and Spirit Character
During distillation, distillers make “cuts” to separate the spirit into heads, hearts, and tails. The hearts, representing the purest and most desirable portion of the distillate, are collected for maturation. The heads (containing volatile compounds like methanol and acetone) and tails (containing heavier, less desirable oils) are typically discarded or redistilled. The precision of these cuts significantly impacts the flavor profile. Scotch distillers often favor wider cuts, resulting in a more robust and complex spirit, while bourbon distillers may opt for narrower cuts, producing a cleaner, smoother spirit. The distiller’s skill in making these cuts is paramount in shaping the character of the whisky.
