Dos Maderas PX 5 + 5 rum is made from a combination of rums from Barbados and Guyana. It is unique becuase of its triple ageding 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.

The Dos Maderas family of rums are produced by Bodegas Williams & Humbert, which is a well known Spanish winery founded by Sir Alexander Williams in the late 1800s. The region of Spain where the winery is located has a climate perfectly suited for wine and is known as Europe's wine cellar.
