What is the maximum distillation proof for bourbon?

The maximum distillation proof for bourbon is indeed 160° (70.0% alcohol by volume). This specification is critical in the production of bourbon, as it ensures that the final spirit retains the distinctive flavors that characterize bourbon whiskey. Distilling at 160 proof ensures that while the spirit is concentrated, it does not strip away too many congeners, which are compounds that contribute to flavor and aroma.

To be classified as bourbon, the spirit must also be distilled from a mash bill that contains at least 51% corn and aged in new charred oak barrels. The combination of these factors helps preserve the integrity of the flavor profile that bourbon is known for.

In contrast, options concerning higher distillation proofs would lead to a product that, while potentially higher in alcohol content, might lack the typical characteristics of bourbon due to the increased removal of flavor components during distillation.
