Appleton Estate Rare Casks 12 Year Old is a true expression of our Master Blender��s craft and passion. The rare, golden rums that make up Rare Casks are hand-selected, and have all been aged for a minimum of 12 years. The long years of tropical ageing give it its rich mahogany hue, confident woody character, and smooth robust taste all of which make a bold statement of extraordinary quality.
