The new 5 star Mukul Resort in Nicaragua is owned by the same family that owns Flor de Cana. They give a short class in Rum, not unlike a wine tasting tour. They explain how their Rum is actually aged for years with imported barrels from Kentucky, etc. They mentioned that Bacardi Rum is only aged one week before shipping to stores.
