Irish whiskey's soft caramel-and-malt warmth sits against the bite of ginger beer and a squeeze of fresh lime, drinking like a Moscow Mule with whiskey where the vodka was. Built over ice in a frosty copper mug, it pours tall, spicy and easy, the lime keeping the ginger bright while the malt rounds off its heat.

No one is credited with inventing the Irish Mule — it took shape as a straightforward spirit swap, trading the Moscow Mule's vodka for Irish whiskey, and both an Irish buck and an Irish mule are now recognized as named members of that family. By structure it is a buck, a style of ginger highball reaching back to the early twentieth century, yet it travels under the "mule" label the 1941 Moscow Mule made famous, though even that parent's own beginnings are disputed. It has since become a St. Patrick's Day favorite that drinkers keep reaching for the rest of the year.
