Whiskey is a broad category of distilled alcoholic beverages made from fermented grain mash, typically including barley, corn, rye, or wheat, and aged in wooden barrels—most often oak. Known for its rich and complex flavour, whiskey can range from sweet and smooth to bold and smoky, depending on the grain used, distillation method, and aging process.

Originating in Scotland and Ireland, whiskey has since evolved into various regional styles, including Scotch whisky, Irish whiskey, American bourbon and rye, Japanese whisky, and Canadian whisky. Each style offers its own unique character, shaped by local traditions and ingredients. Common flavour notes include caramel, vanilla, spice, smoke, and dried fruit, and it is typically enjoyed neat, on the rocks, or in classic cocktails like the Old Fashioned and Manhattan.
