The IslandSlice Story
IslandSlice Rum brings the authentic flavors of the Caribbean to Scotland from our distillery in Dumbarton - affectionately known as "Rumbarton." Founded by Sylvester Herman, a fourth-generation rum maker from St. Lucia, IslandSlice crafts traditional Caribbean rums using methods passed down through generations. Our rum-making process honors the heritage of those who first developed rum in the Caribbean. Using traditional "muck and dunder" fermentation and a combination of column and pot still distillation, we create spirits that capture the true essence of Caribbean rum.
From our signature White Rum to our popular Scotch Bonnet Rum, Dark Rum, and Spiced Rum, each bottle represents the perfect fusion of St. Lucian tradition and Scottish craftsmanship.
