What Is Straight Bourbon? Explained (2022 Updated)

Last Updated on November 6, 2022 by Lydia Martin

The US Congress has legally secured “Bourbon” under the US Law Title 27 of the Code of Federal Regulations since 1964. 

And to be considered straight bourbon, some criteria or requirements must be met. 

But what is straight bourbon in the first place, and what are the requirements to be called one? 

Let’s get to the bottom of it. 

What Defines Bourbon As Straight?

Straight bourbon is a type of whiskey that meets all of the requirements of bourbon according to US law. It must be aged for two years at the minimum.

Before a straight bourbon can be bottled, it must undergo various steps, such as chill filtering, batch whiskey making, and adding water to reduce the proof. 

This ensures that the alcohol content meets the minimum 80-proof requirement. No other blending or coloring agents are allowed.

History & Origin 

Straight bourbon is a type of American whiskey made from corn.

It’s derived from the French Bourbon dynasty, though its exact source of inspiration is unknown. 

Some examples of places named after the dynasty include Bourbon Street in New Orleans and Bourbon County in Kentucky.

In 1964, the US Congress recognized the distinct qualities of Bourbon, which is made from at least 51% corn. 

Since then, bourbon sold in the US must only be made within the country.

Also, US law states that it must be stored using new charred oak barrels, which is in effect until today. 

Straight Bourbon requirements 

Production Process

There’s a concentration limit of 160 proof or 80% ABV [1] during the distillation process, and it should be barreled at 125 proof. 

If blended, both spirits must be the same type, and adding colorings, flavorings, or any blending additives is not allowed. 

Most importantly, the mash bill of straight bourbon must comprise at least 51% corn, and the production process must only take place in the US. 

Maturation

Straight bourbon must be stored in new charred oak barrels.

During the maturation process, bourbon oxidizes and penetrates the wood, resulting in a straight bourbon. 

This process results in the extraction of various flavor compounds, such as sweet and smoky notes.

Age & Alcohol Content

Straight bourbon must mature for at least two years and must be bottled at no less than 80-proof or 40% ABV.

Does Straight Bourbon Have To Be Made In Kentucky?

Not necessarily, as bourbon can be made anywhere within the US. But 95% of straight bourbons are made in Kentucky. 

The state of Kentucky is known for its unmatched history of craftsmanship and is the spiritual home of bourbon. 

Its climate and water supply are ideal for distilling, but straight bourbon can be made outside the state. 

A straight bourbon can be from Indiana or Tennessee as long it meets the straight bourbon requirements. 

But to be called a Kentucky Straight Bourbon, the spirit must be made in Kentucky.
