Flor de Caña Centenario 18 Years Old is matured for at least 18 years in selected small oak barrels, making it one of the brand's longest matured rums. The "SLOW AGED" designation, which Flor de Caña is exclusively authorised to use, has been approved by the strict US government authorities and indicates the natural and non-accelerated ageing process that takes place in the oak barrels.

This careful, slow ageing process produces a rum of the highest quality, whose flavours and textures are allowed to develop fully in a time-consuming process. Flor de Caña is the only rum brand in the world to be labelled "SLOW AGED", which gives it a unique selling point in the rum industry and makes it particularly attractive to connoisseurs and lovers of high-quality, long-matured rums.
