Ron Zacapa rums are made from sugar cane harvested in southern Guatemala, which is pressed into virgin sugar cane honey. The fermentation process (which takes approximately 5 days) uses a yeast strain (saccharomyces cerevisae) isolated from pineapples to transform sugars within the cane honey into alcohol. After fermentation, the fermented ‘wine’ is distilled in a single continuous column.
Zacapa rums are matured using a complicated process they call ‘Sistema Solero’. The subject of my review, Ron Zacapa Centenario 15, is produced from rums which range in age from 5 years to 15 years. The barrels used for aging are a mixture of American Whisky casks, and Sherry and Pedro Ximenez wine barrels. The combination of high altitude aging and the variety of reused oak barrels creates a complex rum with a rich aroma and flavour. This rum is bottled at 40 % alcohol by volume, and available through the duty-free trade (at major airports).
Ron Zacapa is owned by Rum Creation and Products Inc. (RCP), who have signed a global distribution and joint marketing agreement with Diageo.

The El Dorado 25 Year Old Vintage Reserve Rum is a blend of aged rums created to mark the turn of the millennium. It is blended from 25-year-old rum stocks which have been aged in used bourbon oak casks. This is quite different from those rums which feature a solera style age statement which highlights the oldest rum in the blend but also usually includes a high percentage of rum which is much younger.

Just so we are clear, there may be additional benefits gained by resting a spirit in airtight vats; however, it is widely accepted that no further maturation of the spirit occurs in an airtight container. Pumpkin Face 23 is (according to the information provided) a 23 Year Old Rum based upon how long it was resting in oak barrels; the 10 years the rum spent in the stainless steel vats are not included in the age statement.
