Seagram CEO Samuel Bronfman purchased a distillery named Long Pond from the Jamaican government. Among the buyers of raw rum from the Long Pond distillery was a Kingston pharmacy named Levy Brothers. The Levy family had been purchasing raw rum, adding medicinal herbs and spices, aging, and bottling it. Bronfman liked the rum product and bought the rights to it.
In the 1950s the governments of both the United States and its Puerto Rico commonwealth territory instituted a number of job creation programs in Puerto Rico. Taxes on rum entering the contiguous 48 states from Puerto Rico were made lower than those on rum coming from foreign countries. At this time both Seagram's and the Bacardi family built large new plants near San Juan. In 1985, Seagrams sold its rum distillery and manufacturing facilities in Camuy and Arecibo—and doing business as Puerto Rican Destillers—to Destilería Serrallés, a Puerto Rican concern that had been producing the Don Q brand in Puerto Rico since 1865. As part of the contract Seagrams also licensed to Serralles the rights to produce and distribute the "Captain Morgan" brand in Puerto Rico and the rest of the Caribbean until 2012.
