How do you tell the age of a bottle of remy martin Louis xiii?

The age of a bottle of Rémy Martin Louis XIII can be determined by looking at the date of bottling, which is often printed on the label or the box. However, the spirit itself is a blend of eaux-de-vie aged from 40 to over 100 years, so the age refers to the youngest component. Additionally, if the bottle is part of a limited edition or special release, its packaging may provide further clues about its vintage. Collectors also refer to the bottle's design and any unique identifiers to help date it accurately.
