Doorly’s Fine Old Barbados Rum. From the house of Martin Doorly no less. The rum is produced by R. L. Seale at the wonderful Foursquare Distillery. The Foursquare Distillery occupies the site of a former sugar factory that dates back to 1636 and, as one of the most modern and efficient rum distilleries in the world, is designed to be both highly energy efficient and environmentally friendly. The distillery produces light rums in a three-column vacuum still and heavier rums in a modern pot still.RL Seale is one of Barbados’ oldest trading houses, a family-owned business whose involvement in rum-making extends from father-to-son since 1820. Current head distiller, Richard Seale, is one of the region’s most innovative distillers and blenders and has a passion for producing perfect rum with great flavour
