R.L. Seale & Co acquired the Doorly's brand in the 1970s, blending and bottling it for many years using rum produced by other local distilleries before moving production to Foursquare.

The Foursquare rum distillery is owned by R.L. Seale & Co, a family company with a traceable history of rum making in Barbados dating back to 1820. The modern company dates to the 1920s, when Reginald Leon Seale set up a distribution business in the island’s capital, Bridgetown. The company’s success brought expansion, and through the latter half of the 20th century it acquired brands such as ESA Fields and Doorly’s for its portfolio. In 1995 they opened the Foursquare distillery, converting an abandoned sugar factory in the Saint Philip parish. Operating as double retort pot still and a three-column continuous still, its first spirit was produced in 1996. Foursquare produces Single Blended rum, combining its pot and column distillate both before and after being barrelled, and under the direction of Sir David Seale and his son, Richard, has become one of the most revered producers in the world.

Launched in 2019, the Doorly's 14 year old is aged in American white oak bourbon casks and ex-Madeira wood.
