Irish Coffee, a cocktail that originated in Ireland in 1943, has been a popular drink globally since then. The drink was introduced by Joe Sheridan, head chef at The Buena Vista restaurant in San Francisco, after a flight from Foynes, Ireland was forced to return due to severe weather. The cocktail made its way to the US ten years later, and has since become a popular staple at bars and restaurants worldwide. The secret to the drink's balance is Tullamore D.E.W. Irish whiskey, which has been aged for 48 hours and lightly whipped, according to experts at the Irish Whiskey Museum. Despite its popularity, experts predict it will be one of the top 20 cocktails of 2026.
