Does Rum age in the bottle?

Does rum age in the bottle? Rum ages in the barrel, not the bottle. Ageing rum in a barrel helps to mellow out the spicy alcohol flavours, allowing more subtle notes of caramel, vanilla, oak and other nuances to come through. The ageing process takes place slowly over time as the liquid comes into contact with the wooden barrel or cask that it is stored in. As a rule of thumb, rum should be aged for at least 1 year in order to call it “aged” or “aged rum”, however, some may take much longer.

However, it’s worth noting that the flavour of rum can change when it is in the bottle, as it is subject to evaporation, oxidisation, presence of light, etc. This is why it is worth storing your rum in a cool, dry and dark place to ensure that the flavour is preserved for as long as possible.
