Scotch whisky is a type of whisky that is made in Scotland. It must be distilled from malted barley or grain and aged in oak barrels for a minimum of three years. There are two main types: single malt, made from 100% malted barley at a single distillery, and blended, which combines different whiskies from various distilleries. The production of Scotch whisky follows strict regulations, including the use of specific water sources and traditional methods. It is known for its diverse flavors, which can range from smoky and peaty to sweet and fruity, depending on the region and production techniques used.
