What is the minimum ABV for bottling whiskey according to U.S. standards?

The minimum alcohol by volume (ABV) requirement for bottling whiskey in the U.S. is set at 40%. This threshold is established to ensure that the product is sufficiently alcoholic to meet both safety standards and consumer expectations for flavor and quality. At 40% ABV, whiskey can maintain its character and richness while also being palatable to the consumer market.

In addition, the requirement aligns with international standards, particularly those set by the European Union for spirits, which also recognizes whiskey as a product requiring a minimum of 40% ABV for it to be classified as such. This consistency across regions helps in trade and reinforces the quality expectations of whiskey worldwide.

The other options present higher thresholds that do not align with the established regulations in the United States for whiskey, making them incorrect.
