Oliver & Oliver is a Cuban company that originates in Cuba and buys Rums from 5 Caribbean countries. Located in the Dominican Republic, they release several Rums including the Opthimus. All rum for the Opthimus comes from the Dominican Republic. They leave this traditional Spanish-style Rum to mature long before they release it. The 18 year old is a wonderful example of this. They are limited editions; each bottle is numbered by hand.
