Which of the following is a requirement for a bourbon to have its age stated on the label?

For a bourbon to have its age stated on the label, it is a requirement that the bourbon is aged less than 4 years. This regulation ensures that consumers are aware of the age of the spirit, particularly when it is relatively young, as age can influence the flavor profile and quality of the bourbon.

If a bourbon is aged for 4 years or longer, it does not need to have an age statement on the label; however, if it is aged for a shorter period, stating this age is mandatory. This requirement provides transparency for consumers, as it helps them make informed choices based on their preferences and the understanding of potential flavor differences in younger versus older bourbons.
