Scotch is a type of whisky that is made in Scotland. It is typically distilled from malted barley and aged in wooden casks for at least three years. There are two main types of Scotch: single malt, which comes from one distillery and is made from 100% malted barley, and blended Scotch, which combines different whiskies from various distilleries. The production of Scotch is governed by strict regulations, including the requirement that it must be made in Scotland and adhere to specific aging and ingredient standards. Scotch is enjoyed worldwide and is often sipped neat or used in cocktails.
