What must be true for bourbon to be labeled "straight"?

For bourbon to be labeled "straight," it must be aged for a minimum of two years. This requirement is integral to establishing the quality and characteristics associated with straight bourbon. Aging in charred oak barrels allows the spirit to develop complex flavors, contribute to its color, and enhance its overall profile, aligning with the traditional expectations of bourbon consumers.

While there are other factors that influence bourbon’s identity, such as being made from at least 51% corn and being distilled at or below 160 proof, the specific requirement of a two-year aging period is crucial for the legal classification of "straight." It ensures that the spirit has had adequate time to mature, creating the depth and character expected from straight bourbon. Additionally, if a straight bourbon is aged less than four years, it must also carry an age statement on the label.
