Irish whiskeys are predominantly "blends", i.e. whiskeys from different distilleries. But there are also some Irish "single malts" like Wild Geese or Locke's. Another quality designation for Irish Whiskey is "Pure Pot Still". This means the sole use of a pot-still distillation plant.
When blending Irish whiskeys, in contrast to Scottish whiskeys, the combination of different ripening processes in different barrel types (sherry, bourbon, port wine barrels) is used to influence the taste of the whiskey. This form of blending is also called "Vatting" in Ireland.
And since Irish whiskey does not usually use an open peat fire to kiln the malt, so that the malt does not come into contact with the smoke, Irish whiskey is significantly milder (almost sweetish) than the mostly smoky Scottish whiskies. Traditionally, Irish whisky is also triple distilled, while Scottish whisky, with a few exceptions, is generally double distilled. Pot stills in Ireland are also much larger than in Scotland. There, the comparably large Coffey stills are only used for the production of the Scottish Grain Whisky.
