Irish whiskey is whiskey made on the island of Ireland. Most Irish pot still whiskey is distilled thrice, while most Scotch whisky is distilled twice. Peat is rarely used in the malting process, so that Irish whiskey has a smoother finish as opposed to the smoky, earthy overtones common to some Scotches. There are notable exceptions to these rules in both countries; an example is Connemara peated Irish malt (double distilled) whiskey from the Cooley Distillery in Riverstown, Cooley, County Louth. Irish whiskey was once the most popular spirit in the world, though a long period of decline from the late 19th century onwards greatly damaged the industry. Irish whiskey has seen a great resurgence in popularity since the late twentieth century, and has been the fastest growing spirit in the world every year since 1990.
