The Ron Matusalem brand originated in Santiago de Cuba, where it was founded in 1872 by brothers Benjamin and Eduardo Camp, together with their partner Evaristo Alvarez. The name "Matusalem" comes from the biblical figure Methuselah, who is said to have lived to be 969 years old, and symbolizes the long maturation process and quality of the rum. Over the years, Ron Matusalem has faced various challenges, including changes in ownership and production locations due to political and economic factors. After the Cuban Revolution in 1959, the brand changed hands and production was moved to the Dominican Republic, where it continues to flourish.

Insolito is aged for 3 years in ex-tempranillo soler barrels and then blended with the legendary 15 Solera Gran Reserva made in-house. The pink color results from the vewendete activated carbon filtration.

The Insalito still appears only in limited editions.
