Irish whiskey is distilled and matured at least three years on the island of Ireland. It is the lightest and softest corner of the whisky world: clean, fruity and all but smokeless.
It is the lightest of the whiskies, so any swap adds weight — smoke, oak or corn sweetness — and the drink gets heavier rather than different. In an Irish Coffee that matters most, since the whiskey is there to be soft under the cream.
Made in Scotland and sometimes peated, where the Irish is rarely smoky, and in an Irish Coffee the smoke fights the cream, which is why the recipe names the softer one.
Corn and new charred oak make bourbon sweeter and fuller. In an Irish Coffee or a sour the drink gets heavier and picks up vanilla, and the light fruity clarity of the Irish is gone — take less sugar with it.
Triple distillation — one pass more than in Scotland — is where the softness comes from, though it was never a rule.
