Jameson Irish Whiskey 1LJohn Jameson created Jameson Irish Whiskey in 1780. Today, it is still produced according to the founder's exacting standards, including the triple distillation process. Aging takes places in three different types of casks (Bourbon, Sherry and Port) to impart balance and complexity. With its notes of citrus peel, flowers, hay and honey, it is a versatile whiskey to be enjoyed neat or with your favourite mixer.
