Our 10 Year Old Single Malt is a nod to Tullamore D.E.W’s history in unbridled creation, being the only Irish Single Malt in existence matured to perfection in four different types of cask: old bourbon, dry oloroso sherry, port and madeira. Tasting notes: We age this bold single malt for ten years and finish it in old bourbon, dry oloroso sherry, port and madeira casks. Ageing in these specially selected casks enhances the flavour of the whiskey. The glorious Christmas cake taste that results is a unique flavour in Irish whiskey, one which begs further discovery.
