Have you heard that rum improves with age? If so, it's probably important for you to know how to determine a rum's true age.
Because it's not always that simple. Many producers strive to state as high an age as possible on the bottle, which can lead to confusion and misleading information. Therefore, it is important to know how to determine a rum's true age and to read what is actually on the label.
In countries like Barbados, Jamaica, and Guyana, there are strict rules that state that the youngest rum in the blend must indicate the age on the bottle. In other countries, such as Martinique and Guadeloupe, the French V.S./V.S.O.P./X.O. system, also known from cognac, is used to describe a rum's age.
In many Spanish-speaking rum countries, the solera method is used. For solera-aged rums, the opposite principle applies – here, the age of the oldest rum in the blend is what's stated on the bottle. (Read more about aging rum). So, if a rum says '30 anos Solera', it simply means that only the oldest rum in the blend is 30 years old. And there is no requirement for what proportion of the blend the oldest rum must constitute.
Finally, whether a rum has been aged in a tropical or continental climate has a significant impact on its age. It is said that a rum ages 3 times faster in a tropical climate than it does in a continental climate. This means that a rum aged 8 years in a tropical climate can be compared to a rum aged 24 years in a continental climate.
Uncovering a rum's true age thus requires knowledge of the rules and methods used in different countries and regions. But now you know what to look for, so you are equipped to determine what you're getting for your money the next time you buy a bottle of rum.
