Which of the following is allowed in blended bourbon?

Blended bourbon is a category that allows for more versatility in production compared to traditional straight bourbon. By its definition, blended bourbon can include the use of coloring, flavoring, or other spirits alongside the primary bourbon component. This means that whereas straight bourbon must adhere strictly to regulations regarding its production and contents, blended bourbon has the flexibility to incorporate these additional elements to achieve a desired flavor profile or appearance.

The incorporation of coloring agents or flavoring allows producers to create a consistent product despite variations that may arise from different batches. Other spirits can also be blended with bourbon to create a unique final product, which broadens the possibilities for distillers aiming to appeal to varying consumer preferences and tastes. Thus, the inclusion of these elements is what makes blended bourbon distinct from pure or straight bourbon, adhering to the regulations established for this specific category of spirits.
