The sugar cane plantation they built virtually became a company town, and eventually had its own rail line, workers' housing, transportation fleet, commissary, and private—later public—airport (Ponce's Mercedita Airport).In that year, Juan Serralles Colon, who would go down as one of the most successful liquor salesmen in Puerto Rican history, imported a still from France, which enabled him to produce his first casks of rum.This acquisition increased the company's product line to include Palo Viejo, Ron Llave and Granado, and doubled the firm's sales.[4] The acquisitions included manufacturing facilities in Camuy and Arecibo plus the brand names sold by Seagrams locally such as: "Palo Viejo", "Ron Llave" and "Granado".[11] The company's flagship product, Ron Don Q, is currently sold in the United States, Mexico, the Virgin Islands, Spain, and a number of other countries.[13] The Captain Morgan Rum brand is owned by Diageo PLC but made by Destilería Serrallés in a different Puerto Rican distillery under a supply contract.
