What does the term "barrel strength" indicate about the distillate?

The term "barrel strength" indicates that the distillate has had no water added after it has been drawn from the barrel. This means it is bottled at its natural proof, which can be significantly higher than typical bottled offerings that are often diluted before bottling. By retaining this strength, barrel strength spirits present a more intense flavor and aroma profile, showcasing the character imparted by the aging process in the wood barrel. Understanding this term is crucial for appreciating the richness and complexity of the flavors found in such bourbons, as they reflect the unaltered essence directly from the barrel.
