Which whisky brand is recognized as an Irish whiskey?

Bushmill's is recognized as an Irish whiskey due to its origin. It is produced at the Old Bushmills Distillery in Northern Ireland, which was granted its license to distill in 1608, making it one of the oldest distilleries in the world. Irish whiskey is characterized by its triple distillation process, which typically results in a smoother and lighter style than some whiskies from other regions.

The other brands listed are not Irish whiskeys. Blanton's is a well-known bourbon whiskey from the United States, specifically from Kentucky. Jim Beam is another prominent American bourbon brand, also originating from the United States. Johnnie Walker is a famous Scotch whisky brand from Scotland, known for its blended whiskies. Each of these brands represents different styles and traditions of whisky, distinguishing them from the unique characteristics associated with Irish whiskey such as Bushmill's.
