Are Whiskey and Bourbon the Same? No, but they’re closely related. Whiskey is a broad category of distilled spirits made from fermented grain mash, while bourbon is a specific type of American whiskey with strict production requirements. All bourbons are whiskeys, but not all whiskeys are bourbons. The key differences lie in their ingredients, production methods, and legal regulations. Bourbon must be made in the USA, contain at least 51% corn in its mash, and age in new charred oak barrels, among other requirements. This guide will explore the nuances that set these beloved spirits apart and provide insights for both novices and connoisseurs.
Are Whiskey and Bourbon the Same?
What is Whiskey?
Definition and General Characteristics
Whiskey, derived from the Gaelic term “uisce beatha” meaning “water of life,” is a distilled alcoholic beverage made from fermented grain mash. According to the Alcohol and Tobacco Tax and Trade Bureau (TTB), whiskey must be distilled to no more than 190 proof (95% alcohol by volume) and bottled at no less than 80 proof (40% alcohol by volume).
Varieties of Whiskey
The whiskey family encompasses several distinct types, each with its own production methods and flavor profiles:
- Scotch Whisky: Produced in Scotland, known for its often peaty and smoky flavors.
- Irish Whiskey: Typically triple-distilled, resulting in a smoother taste.
- American Whiskey: Includes bourbon, rye, and Tennessee whiskey.
- Canadian Whisky: Often lighter and smoother than its American counterparts.
- Japanese Whisky: Inspired by Scotch but with its own unique characteristics.
Distillation Process and Key Ingredients
The whiskey production process involves several key steps:
- Malting: Grains are soaked in water to germinate, then dried to stop the process.
- Mashing: The malted grains are mixed with water and heated to convert starches to sugars.
- Fermentation: Yeast is added to convert sugars into alcohol.
- Distillation: The fermented liquid is heated in stills to separate the alcohol.
- Aging: The distilled spirit is matured in wooden barrels, often oak.
The choice of grains, water source, and aging process all contribute to the final flavor profile of the whiskey.
What Makes Bourbon Different from Whiskey?
Definition and Legal Requirements
Bourbon is a type of American whiskey, but with specific legal requirements as defined by the Federal Standards of Identity for Distilled Spirits:
- Must be produced in the United States.
- Made from a grain mixture that is at least 51% corn.
- Aged in new, charred oak containers.
- Distilled to no more than 160 proof (80% alcohol by volume).
- Entered into the barrel for aging at no more than 125 proof (62.5% alcohol by volume).
- Bottled at 80 proof or more (40% alcohol by volume).
- No additives allowed other than water for proofing.
The Role of Corn in Bourbon Production
The high percentage of corn in bourbon’s mash bill (at least 51%) contributes significantly to its flavor profile. Corn imparts a natural sweetness to the spirit, which is further enhanced during the aging process as the whiskey interacts with the charred oak barrels.
Chemical Processes Distinguishing Bourbon
The unique production process of bourbon leads to specific chemical reactions that contribute to its distinct flavor:
- Caramelization: The charred oak barrels cause sugars in the whiskey to caramelize, creating flavors of vanilla and caramel.
- Esterification: Acids and alcohols in the bourbon react to form esters, which contribute fruity and floral notes.
- Oxidation: Exposure to oxygen through the barrel’s pores leads to the development of nutty and woody flavors.
