Scotch whisky and Bourbon are both types of whiskey, but several key differences in their production methods, ingredients, and regional origins make them distinct. Scotch whisky, often referred to simply as Scotch, is produced in Scotland. Scotland is known for its long history of whisky production, and it has several distinct whisky regions, including Speyside, Islay, Highlands, Lowlands, and Campbeltown, each known for its unique style of Scotch. Bourbon is a type of American whiskey that must be produced in the United States to be considered Bourbon. While Bourbon can be made anywhere in the U.S., it is most strongly associated with Kentucky, often referred to as the world’s Bourbon capital.
Other distinctions between these two types of whiskey include:
Grains Used
- Scotch: Scotch is typically made from malted barley or a blend of malted barley and other grains such as wheat and corn. Single malt Scotch is made entirely from malted barley and produced at a single distillery.
- Bourbon: Bourbon must be made from a grain mixture that is at least 51% corn. The remainder of the grains used in Bourbon production can include malted barley, rye, and wheat.
Distillation
- Scotch: Scotch is often distilled using pot stills or a combination of pot stills and column stills. It is distilled to a lower proof than Bourbon, resulting in a lighter spirit.
- Bourbon: Bourbon is typically distilled to a higher proof than Scotch, often around 160 proof (80% alcohol by volume) or higher, and is usually distilled using column stills.
Aging
- Scotch: Scotch is aged in oak barrels for at least three years, although many Scotch whiskies are aged for much longer. The type of oak used for aging can vary, and some Scotch whiskies may be aged in used sherry or wine casks, which impart additional complex flavors.
- Bourbon: Bourbon must be aged in new charred oak barrels, contributing to its distinct caramel and vanilla flavors. Bourbon has no specific minimum aging requirement, but to be called “straight Bourbon,” it must be aged for at least two years. However, many Bourbons are aged for several years to develop their flavors.
Flavor Profile
- Scotch: Scotch often exhibits a wide range of flavors, which can vary based on the production region. Typical flavor notes in Scotch include peat smoke, heather, honey, fruit, and oak.
- Bourbon: Bourbon is known for its sweet and rich flavors, with notes of caramel, vanilla, oak, and sometimes hints of spice. The new charred oak barrels used for aging contribute significantly to Bourbon’s rich flavor profile.
Of course, within both Scotch and Bourbon categories, there are significant variations in flavor and style, depending on the specific distillery, aging process, and recipe used. These differences make exploring the world of whiskey a rich and diverse experience for enthusiasts.
