Irish whiskey is almost as famous as the single malts from Scotland. The marketing point for most Irish whiskeys is that they are triple distilled, making them ultra smooth (most Scotch is double distilled). There are various types, ranging from blended to single pot still to single malt.
A typical Irish whiskey has flavors of smoked peat, honey and even notes of dried fruit and blossoms. The finish is long and spicy, often with notes of oak and hints of pepper. Some examples are aged in sherry barrels and display more of a roasted nut and toffee character.
Irish whiskeys are very popular with consumers in the US market.
There is also a few distillers in Ireland that distill vodka and gin.
