What characterizes Straight Bourbon compared to regular Bourbon?

Straight Bourbon is specifically defined by legal regulations that dictate its production standards. One of the key characteristics of Straight Bourbon is that it must be aged for at least 2 years in new charred oak barrels. This aging process is crucial because it allows the whiskey to develop its flavors, color, and aroma, making it distinct from regular Bourbon, which may not have the same aging requirement.

While options like aging in Kentucky, having a unique flavor profile, or allowing color additives are relevant to understanding bourbon as a broader category, they do not specifically delineate Straight Bourbon from other types. Straight Bourbon is distinguished by its minimum aging requirement, ensuring a certain level of quality and complexity that comes with time spent in the barrel. Thus, option B accurately captures this defining feature of Straight Bourbon.
