This toasty cocktail comes with a shot of history—and improvisation.
Whatever it is you're toasting, Irish coffee fits the occasion. Originally created in Ireland more than 60 years ago to warm up the weary, this bracing drink traditionally contains coffee, sugar, whiskey, and cream. But ask any bartender and you'll find more ways to mix one than rhymes in a bawdy limerick.
Glass Normally served in a tall glass mug with a handle, Irish coffee also shows up in the occasional wineglass. Some bars, like Fado Irish Pub, heat the glass first.
Sugar A teaspoon or two of brown sugar may be traditional, but even San Francisco's Buena Vista Cafe—credited with bringing the drink across the pond—uses white sugar cubes.
Alcohol Purists shudder at the thought of using anything other than good Irish whiskey. But Baileys is a frequent addition, and, as John McCormack of the British Bulldog says, "Coffee with Jameson and Baileys is what 80 percent of the people expect."
Coffee House drip coffee is standard, but Solera will serve it with a caffè Americano if you ask.
Cream An Irish coffee wouldn't be the same without that signature float of cream. But should it whipped or not? Sweetened or not? Handmade or not? Unadorned or not? At Strings, the whip is gussied up with a touch of Kahlúa and Triple Sec, while other spots drizzle crème de menthe, a popular but heretical treat.
