The Oliver & Oliver story begins with Juanillo Oliver in the mid-nineteenth century. A Catalan in the Spanish military, Juanillo ended his military service in 1868 and established himself in the idyllic Las Placetas in Cuba. Today Oliver & Oliver produce the Cubaney rum brand in the Dominican Republic. This company is known to purchase rum from other countries to mature the distillates themselves. Oliver & Oliver get their distillates from Guatemala, Trinidad, Nicaragua and Colombia.
During the entire aging period in the solera systems, the individual casks are followed and analyzed by the blenders. Oliver & Oliver are known for using different "rum components". They have, for example, a component called "mother rum" and a component called "compuesto". The mother rum is included in virtually all their bottlings and has an average age of 25 years. This adds a lot of depth and sweetness to the different series of rum. The compuesto is a very old rum with lots of oak flavor and bitter tannins, which in themselves are not comfortable to drink, but which adds a lot of complexity to the final blend.
