Cork has a long and storied history of distilling stretching back to the late 1700's. In 1867 four of these distilleries (Daly's, the Green, North Mall, and the Watercourse) merged to form the Cork Distilleries Company (CDC) which became a powerhouse in Irish distilling.
Originally licensed to distill by King James in 1608 there are records of distilling on the current site of the Old Bushmills distillery since the late 1700's. Located on the beautiful north Antrim coast, Bushmills has been synonymous with Irish whiskey for centuries. At one stage during the dark days for Irish whiskey it was one of only two operating distilleries on the island and was also owned by Irish Distillers/Pernod Ricard for a period of time.
Green Spot is a single pot still Irish whiskey, produced specifically for Mitchell & Son of Dublin by Irish Distillers at the Midleton Distillery in Cork, Ireland.
Redbreast is synonymous with the unique style of Irish whiskey making that is Single Pot Still. Impressively the Redbreast "round" (One of the collective nouns for a group of robins) is the fifth most popular Irish whiskey by volume (cases sold) in America.
Powers has always been regarded as the "Best" Irish whiskey of the big brands and from its founding in 1791 by James Power, an inn-keeper just outside the old walls of Dublin City it has always been known as an innovative brand.
Dublin, also known as "The Fair City," was a global distilling powerhouse back in the days when Irish Whiskey ruled the world. But as with the industry island-wide, these distilleries one-by-one shut their doors until only two remained in the 1960's - Powers and Jameson. Both of these distilleries closed their doors in the 1970's when their operations were moved to Midleton in Co. Cork as part of the formation of Irish Distillers Ltd. (IDL) along with Cork Distilleries Company.
