When Two Spirits Traditions Share Casks
Mossburn built the Cask Collaboration Series around one question: what happens when two entirely different spirits traditions borrow each other's casks? For the first release, the answer came from Foursquare — the Barbados distillery counted among the world's most respected rum producers — which supplied American oak casks from its own St. Philip distillery. Mossburn's master blender married mature Speyside single malts into a nutty, honeyed vatting and finished it in those rum casks, adding rich muscovado depth to the malt.
Tasting Notes
Dark cane sugar, molasses, and banana on the nose give way to ripe banana and tropical sweetness on the palate, with caramelized sugar and orchard fruit beneath. The finish is warm, sweet, and long — the Speyside malts enhanced, not transformed, by the rum casks.
How to Enjoy
Neat with a drop of water to lift the tropical notes, or over one large cube as an after-dinner Scotch whisky. The 57.7% strength carries through dilution beautifully.
