Bourbon is a type of whiskey that is produced exclusively in the United States. It has specific regulations that must be met for the product to be legally labelled as ‘bourbon’. So, what are these parameters? And what are the differences between bourbon vs. whiskey? Let’s break down the legislation.
All bourbon is whiskey…
According to the Alcohol and Tobacco Tax and Trade Bureau, American whiskey is any whiskey produced, aged, and bottled in the United States that meets the following requirements:
- Made from a fermented mash of grain
- Distilled at no more than 190 proof (95% ABV)
- Made in such a manner that the distillate possesses the taste, aroma, and characteristics generally attributed to whiskey
- Stored in oak barrels (except corn whiskey)
- No minimum time for storage/maturation
- Bottled at a minimum of 80 proof (40% ABV)
- Can include mixtures of such distillates for which no specific standards of identity are prescribed
- Does not need to be made in Kentucky (although most American whiskey is made in Kentucky)
…not all whiskey is bourbon
The above regulations are all-encompassing regulations for American whiskey. There are numerous different types of American whiskey including bourbon, straight, blended, light, oat, rye, wheat, malt, rye malt, corn, and spirit.
For clarity, let’s focus just on bourbon, straight bourbon whiskey, and bottled-in-bond straight bourbon whiskey.
Bourbon, according to the American Bourbon Association, must meet the following requirements:
- Made from a fermented mash that is at least 51% corn
- Other grains added can be rye, wheat, and malted barley
- Distilled at a maximum of 160 proof (80% ABV)
- Must be decanted into barrels at a maximum of 125 proof (62.5% ABV)
- No minimum aging period
- Must be matured in new charred oak barrels
- Must not contain any additives or coloring
- Distilled, matured, and bottled in the United States
To be labeled as ‘straight bourbon whiskey’, the bourbon must be aged for a minimum of two years.
For a bourbon to be labeled as ‘Bottled in Bond straight bourbon whiskey’, the whiskey must be distilled in a single season at one distillery (January-June or July-December). It must also be aged for a minimum of four years and bottled at 100 proof.
Other Types of American Whiskey
As mentioned above, there are numerous types of American whiskey, most of which are known by the ingredient that makes up the majority of the mash used in distillation (rye, wheat, etc…). These whiskies must meet the legal requirements for American whiskey but need not meet the requirements for bourbon. Some of the categories have their own requirements as below:
