Bourbon that has an age stated on its label must be labeled with the age of the youngest whiskey in the bottle (not counting the age of any added neutral grain spirits in a bourbon that is labeled as blended, as neutral-grain spirits are not considered whiskey under the regulations and are not required to be aged at all).
Os bourbons que indican na etiqueta a súa idade deben levar a idade do whisky máis novo empregado na botella (sen contar a idade de calquera licor neutro de gran agregado nun bourbon que se etiqueta como blended, un licor neutro de gran non é considerado whisky polos regulamentos e non están obrigados a ser envellecidos).
