Tullamore Dew: The Legendary Irish Whiskey. Triple distilled. After triple distillation, Tullamore Dew is matured in selected oak barrels, where it develops its delicate flavour over a period of six to eight years, and acquires its unmistakable character through careful blending. The special malt drying process gives Tullamore Dew a soft bouquet that differs from the smoky peat taste of scotch. 40% vol. 700ml.
