Tullamore Dew Irish Whiskey originates from the town of Tullamore in Ireland and was launched in 1829. Tullamore Dew is the second best-selling whiskey in the world. Tullamore Dew Irish Whiskey is aged for 4 years in old oak barrels and then undergoes a unique production process involving triple distillation and drying in closed ovens. This process allows the whiskey’s natural, pure flavor to shine through in the finished product.
