What must bourbon meet to be classified as Bottled In Bond?

To be classified as Bottled In Bond, a bourbon must indeed meet several specific criteria that ensure its quality and authenticity. First, it must be produced in a single distillery during a single distillation season, which means it cannot be a blend from multiple distilleries or different years. This requirement maintains a distinct flavor profile associated with that distillery.

Additionally, Bottled In Bond bourbon must be aged for at least four years. This aging process is critical; it allows the flavors to develop and mature, contributing to the complexity and character of the bourbon.

Lastly, to bear the Bottled In Bond label, the bourbon must be bottled at exactly 100° proof (50% alcohol by volume). This higher proof level assures consumers of the potency and robustness of the spirit.

Given these criteria, it is clear that all these requirements work together to define what Bottled In Bond means, emphasizing quality and authenticity in the production of bourbon. Thus, the choice that states all of these conditions must be met is the correct one.
