Bourbon vs. Scotch: A Whiskey Comparison

You probably already know by now that all whiskey isn’t the same. There are many types of whiskey, including but not limited to bourbon and Scotch. Bourbon and Scotch, two of the world’s most celebrated spirits, have captured the hearts of enthusiasts and connoisseurs for centuries. While there are some basic similarities between these spirits, there are still some notable differences. In this comprehensive guide, we’ll compare bourbon whiskey to Scotch whisky, shedding light on what makes them distinct and exceptional. 

The Great Whiskey Divide: Bourbon vs. Scotch

Bourbon is a type of American whiskey made from at least 51% corn in its grain mixture. It is one of the most sought-after whiskeys in the world, and it’s typically known for its sweet and bold flavor profile. Bourbon is deeply embedded in American history, with a heritage that dates back to the late 18th century. It was named after Bourbon County, Kentucky, where it was first distilled. 

The production of bourbon comes with a set of strict rules that distilleries must abide by. Bourbon must be produced in the United States, the mash bill should contain at least 51% corn, be distilled at no more than 160 proof (80% ABV), have no additives, and be aged in new charred oak barrels.

Scotch, on the other hand, hails from the rugged landscapes of Scotland, where the art of whisky-making can be traced back to the early 15th century. Scotch whisky contains more malted barley than any other ingredient and is aged in oak casks for at least three years. It should be produced in Scotland and distilled at a minimum of 80 proof (40% ABV).

Ingredients matter: The Mash Bill vs. The Grains

The ingredients used in the production of bourbon and Scotch play a crucial role in shaping the flavor and characteristics of these spirits. 

In bourbon production, the primary grain used is corn, and the mash bill must contain at least 51% of this ingredient. As the dominant grain, corn gives bourbon its sweet and mellow flavor. It contributes to the spirit’s characteristic sweetness and often lends notes of vanilla and caramel. The remaining grains can include a combination of rye, wheat, and barley. When rye is included in the mash bill, it imparts a spicy and peppery character to bourbon. Wheat helps to soften the texture of the spirit, while barley aids in fermentation. 

Scotch whisky allows for greater variation in terms of the grains used, and the grains can vary depending on different types of Scotch. Many Scotch whiskies are made primarily from malted barley, especially single malt Scotch. Others include grain whisky, which can be made from a mixture of grains like corn, rye, wheat, and barley. In some regions of Scotland, peat is also used in the malting process. Peat gives the spirit a distinctive “smoky” and “peaty” flavor profile. 

Distillation Techniques: Bourbon’s Sweet Simplicity vs. Scotch’s Complexity

The distillation techniques used in bourbon tend to result in a sweeter and more straightforward flavor profile. Many distilleries use column stills (also known as continuous stills) for distillation. Column stills allow for efficient and continuous distillation, resulting in a smoother and more refined spirit. Some distillers, however, use pot stills, which often result in a more robust and complex character. Additionally, bourbon is distilled no higher than 160 proof (80% ABV). This distillation proof contributes to the spirit’s characteristic flavors. 

In contrast, Scotch whisky has a wider range of distillation techniques, which can lead to greater complexity and diversity in flavor. Many Scotch whiskies, especially single malts, are distilled in pot stills. Pot stills are known for preserving the character of the raw materials, resulting in a more complex flavor profile. Other whiskies undergo multiple distillations, which can result in a lighter and smoother spirit. Scotch whisky is distilled and bottled at a minimum of 80 proof (40% ABV). 

Barrel Influence: New Oak vs. Aged Oak 

The choice of barrel type plays a significant role in shaping the flavor profiles of both bourbon whiskey and Scotch whisky. Bourbon is typically aged in new, charred oak barrels, which impart oak-driven flavors such as vanilla and caramel to the whiskey. Scotch whisky, often matured in aged oak barrels, gains complexity from interacting with the remnant of previous barrel contents. 

Aging Process: The Role of Time in Whiskey Maturation

Bourbon can be aged for any amount of time. However, there are some exceptions to this, bottled-in-bond whiskey has to be aged for at least 4 years, and straight bourbon whiskey must be aged for a minimum of 2 years. The aging period for bourbon allows it to retain a significant amount of its grain character and imparts flavors from the new oak barrels. 

Scotch whisky, especially single malt Scotch, is known for its extended aging periods. It’s not uncommon for Scotch to be aged for 10, 15 or more years. The prolonged maturation allows for a gradual development of flavors and complexity. Over time, the spirit interacts with the wood and the previous contents of the barrels, resulting in a rich and nuanced flavor profile. 

Flavor Profiles: Tasting Notes and Palate Differences

Bourbon vs scotch - Flavor Profile

Bourbon and Scotch whisky have distinct flavor profiles and tasting notes due to differences in production methods, ingredients, and aging. Bourbon tends to be sweeter with flavors like caramel, vanilla, toasted oak, and honey. You may detect notes of cinnamon and black pepper. Some bourbons have fruity undertones, such as cherry or apple. 

Scotch is known for its complexity and layered flavors, which can include hints of toffee, spices, and nuts. Depending on the region, Scotch can have floral and fruity notes such as citrus, apple, or dried fruits. Some Scotch whiskies, especially from Islay, have a pronounced smoky and peaty character. 

On the palate, bourbon tends to have a smoother and denser texture, often described as “velvety,” while Scotch whisky can vary in texture, ranging from light and delicate to oily and full-bodied.
