Enjoyed widely across the world, this classic mix of coffee and Irish whiskey wasn’t invented until the early 1940s. The story goes that Joe Sheridan, chef at Foynes Port near Limerick, an airbase for transatlantic flights, added Irish whiskey to coffee to warm cold and weary passengers who had their flight delayed due to poor weather conditions. Irish coffee became a popular speciality at the airport and in the 1950s it became a huge hit in the United States.
