Dos Maderas PX 5 + 5 rum is made from a combination of rums from Barbados and Guyana. It is unique because of its triple ageing process where for 5 initial years the rum is aged in the Carribean in oak casks. Next PX 5 + 5 is aged in Spain for 5 years in sherry casks, and lastly for 2 more years in even older sherry casks. Sweet on the palate and very smooth
