At what ABV must rum be bottled according to US regulations?

According to US regulations, rum must be bottled at a minimum alcohol by volume (ABV) of 40%. This standard helps ensure that the spirit maintains its character and quality, as well as aligning with the regulations that govern the labeling and classification of distilled spirits in the United States. The 40% ABV requirement is consistent with the threshold set for many types of spirits, including whiskey and vodka, thereby providing a uniform standard across various distilled beverages. This regulation aims to protect consumers by ensuring that they receive a product that meets the expected potency typical of spirits.
