Jameson Irish whiskey is produced from a mixture of malted and unmalted or "green" Irish barley, all sourced from within a fifty-mile radius around the distillery in Cork. The barley is dried in a closed kiln fired by natural gas (formerly anthracite coal). This is in contrast to the traditional method used in Scotch whisky production, which fires the kiln with peat, adding a distinctive peat flavour.
Originally one of the six main Dublin Whiskeys, Jameson is now distilled in Cork, and is by far the best selling Irish whiskey in the world
