The Port Mourant distillery was built in 1732 and closed in 1955. Its double pot still built from Guyanese wood—Chlorocardium Rodiei (Greenheart), generally used for shipbuilding due to its good water resistance, which offers properties similar to copper for purifying sulphur compounds—was moved to Albion when Port Mourant closed, then Uitvlugt, and finally Diamond when Uitvlugt closed in 1999. It is known for producing a heavy, oily rum, bringing lots of relief to the famous navy rums so dear to the Royal Navy.

A single cask Port Mourant (#95) distilled in 1990 and bottled in 2007. Rightly considered one of the most important bottlers of his era, Silvano Samaroli was above all a spirits lover and pioneer. He began his career in the late 1960s, initially as an importer in Italy, where he distributed the Linkwood single malt and numerous blends. His bottling activities only began in the following decade with a cask strength bottling of Bruichladdich 10 Year Old 1965. At a time when single malts were far less popular than blends, Samaroli embarked on a meticulous selection and bottling project in close contact with distilleries and, more importantly, Scottish independent bottlers. A champion of single casks bottled at cask strength, he was also fascinated by ageing in bottle. A visionary in many respects, many of his bottlings, such as Bowmore Bouquet 1996 and the 1948 West Indies Rum, are today some of the most legendary spirits ever bottled. More than just a player in the bottling industry, Silvano Samaroli was one of its founding icons. A limited edition of 366 bottles.
