In the 19th century, Irish whiskey ruled the world. But that didn’t last long… By the 20th century, Scottish malt had taken over as the world’s most popular whisky. Remarkably, at some point, Ireland only had three working distilleries. That’s on the change now, as smaller producers have joined the big guys (most notably Jameson and Bushmills) to vault Irish whiskey to the forefront again. Very little peat is used in Irish whiskey (although there is some) and the style is smooth and fruity, thanks in no small part to being triple distilled (although again, there are variations in the distillation process).
