Which type of Irish whiskey is made from 100% malted barley?

Irish Malt Whiskey is specifically made from 100% malted barley, which is a key characteristic that sets it apart from other types of Irish whiskey. The production process for Irish Malt Whiskey generally involves mashing malted barley, fermenting it, and then distilling it in pot stills. This process enhances the flavor profile, often resulting in a smooth and rich taste that is reflective of the quality of the malted barley used.

In contrast, Irish Grain Whiskey typically contains a mixture of grains and is often produced using continuous column stills, leading to a lighter flavor. Irish Pot Still Whiskey, while made with malted and unmalted barley, does not meet the criterion of being made from 100% malted barley. Irish Blended Whiskey is a combination of different whiskey types, including both malt and grain whiskies, and therefore does not exclusively consist of malted barley. Thus, Irish Malt Whiskey is the only category among the choices that fully embraces the 100% malted barley characteristic.
