What is "Irish whiskey"?

Irish whiskey is a type of whiskey that is distilled and aged in Ireland. It is made from a blend of grains, typically including malted and unmalted barley, as well as other grains such as corn or wheat. Irish whiskey is distilled three times, which gives it a smooth and mellow flavor profile. It is then aged in oak casks for a minimum of three years, which imparts flavors of vanilla, caramel, and wood. Irish whiskey is available in a variety of styles, including single malt, blended, and pot still whiskey, which is made using a combination of malted and unmalted barley. Irish whiskey is often consumed neat or on the rocks, and is also used in cocktails such as the Irish coffee and the whiskey sour.
