Which type of bourbon must be made from at least 51% corn and aged for at least 1 year in Kentucky?

The correct answer is that Kentucky Bourbon must be made from at least 51% corn and aged for at least one year in the state of Kentucky. This specification is rooted in the regulatory definitions set forth by the Bourbon industry, where geography plays a crucial role in defining the characteristics and authenticity of the whiskey produced.

Kentucky Bourbon is recognized as a designation that emphasizes its origin from Kentucky, which has a long-standing tradition of bourbon production. While it must contain at least 51% corn to qualify as bourbon, this type also adheres to the broader regulations governing bourbon production, including other ingredients and aging processes.

Other types such as Straight Bourbon may also meet the corn requirement but include additional stipulations regarding aging and production processes, while Blended Bourbon involves a combination of straight bourbon with other spirits, which alters the classification. Small Batch Bourbon refers to a specific production method rather than a strict composition of ingredients and aging. Thus, the unique requirement of being produced in Kentucky under these parameters distinctly identifies Kentucky Bourbon.
