Blends (such as those popularized by Jameson and Bushmills) typically combine grain and malt whiskeys.
Irish single malts, like their Scottish counterparts, must be distilled from a mash of only malted barley at a single distillery and then aged in oak for three years.
Irish grain whiskeys remain a relatively new category and involve the distillation of corn, wheat, rye or barley, or a combination of these grains.
Most recognizable and exclusive to Ireland, though, are single pot or pure pot still whiskeys, which employ a mix of malted and unmalted barley. Originally, the addition of unmalted barley was for economics, but the resulting taste revealed a spicier character that caught on. That pure pot still method is a classic way to produce Irish whiskey.
