At Merser & Co, we have brought back to London the craft of rum blending – the way rum used to be made. We source the very best of rums from Jamaica, Barbados and Dominican Republic aged for up to 12 years before blending them together with skill, care and pure London Rum passion. Our rum is then stored in barrels in small batches in London for a period of six months – each barrel has just enough for 400 bottles of rum. This process is called “Double Barrel” allowing the different flavours and aromas of the rum to gently harmonize together for a smoother, refined finish – the way rum should be made and enjoyed. Merser & Co is London’s first Rum Blending House for more than 100 years and marks a return to rum blending by the Hayman Family, best known not only for their eponymous range of gins, but also as one of London’s original rum merchants. Merser Rum. Distilled in the Caribbean. Made in London.
