What is the "original" International Coffee Drink invented by Joseph Sheridan?

The original International Coffee Drink invented by Joseph Sheridan is Irish Coffee. This drink combines hot coffee, Irish whiskey, sugar, and a layer of cream on top, creating a unique blend of flavors and textures. Joseph Sheridan, a bartender in Ireland, is credited with developing this drink in the 1940s to warm and comfort transatlantic travelers arriving at the Foynes airport. The combination of the robust flavor of coffee with the rich taste of Irish whiskey, along with the creamy top layer, distinguishes Irish Coffee from other coffee drinks, making it an iconic and internationally recognized beverage in the coffee category.

Other options mentioned, such as the Espresso Martini, Café Americano, and White Russian, while popular in their own right, do not have the historical significance or the unique combination of ingredients that define Irish Coffee as the first International Coffee Drink created by Sheridan.
